Hybrid

### Distinction

* An amalgamated species that possesses the combined traits and abilities of two or more supernatural species.

**Hybrids** are a cross-breed of two or more different supernatural species. The term is commonly used to describe a werewolf turned into a vampire due to the fact that they were the first supernatural hybrid to be introduced in the series. However, since the werewolf-vampire hybrid's creation, there have been other cross-breed hybrids revealed in the series' universe, such as Siphoner turned witch-vampire hybrids, werewolf-witch hybrids, and, in the unique case of Hope Mikaelson, a witch-werewolf-vampire tribrid.

Hybrids possess both the strengths and some of the weaknesses of their parent races, along with powerful attributes unique to themselves alone due to their combined heritage. For werewolf-vampire hybrids, this includes Day Walking and being able to transform into a wolf without the Full Moon's influence. For siphoner-vampire hybrids, they retain their ability to siphon magic and their own vampirism as a power source for their use in witchcraft; as they did not possess their own magic as humans, this is a skill that makes them powerful.

## Creation of Werewolf-Vampire Hybrids

To become a werewolf-vampire hybrid, a werewolf must have either Klaus or Hope's Blood in their system before they are killed so they can awaken a short time later in transition. Because no regular vampire has ever attempted to use their own blood to turn a werewolf into a hybrid, it is likely that such an attempt would be unsuccessful. After a werewolf dies with Klaus' blood in their system, their transformation will be successful only if the wolf completes his/her transition by drinking the blood of a human doppelgänger. If a werewolf is turned with Hope's blood, her blood can also be used to complete their transition as well, just as a doppelgänger's blood would. So far, all hybrids have been created by Klaus; with the exception of Dwayne, Hayley, and Henry Benoit, who were created by Hope Mikaelson.

Only one hybrid, Niklaus Mikaelson, has been turned into a hybrid before triggering his werewolf gene. (This excludes his daughter Hope Mikaelson, who was born a hybrid). However, since Klaus is the Original hybrid and was turned into a hybrid with dark magic performed by his mother Esther as opposed to being turned by another hybrid's blood, it is unknown if untriggered werewolves can be turned into hybrids successfully via the normal procedure. If it were possible, the werewolf would presumably trigger their werewolf gene during their first kill as a vampire following the completion of their transition by feeding on the blood of a doppelgänger or Hope Mikaelson. However, this has never been done before and concrete details are still unknown.

If a newborn hybrid feeds on regular human blood to officially complete their transition, the hybrid will become unstable, causing them to bleed from the eyes, become rabid, and eventually die in pain. This result was demonstrated during Klaus' first attempt to turn werewolves into hybrids in *The Hybrid*, after he sired Paige's Pack. However, it is unclear why that happens. It might be a reaction to being fed the wrong blood in transition in addition to feeling the effects of the full moon overhead. After Klaus sired Paige's pack, they all began to experience unbearable pain and profuse bleeding from their facial orifices until they either killed each other, were mercy-killed by Klaus, or dying of failed transitions combined with exsanguination.

It was initially believed that since the doppelgänger (Elena) was resurrected, that the ritual wasn't fully complete, which is why Klaus' first batch of hybrids failed in transition. Bonnie Bennett, an experienced witch, initially confirmed this. However, after Matt Donovan received a message from the ghost of his sister Vicki, who had contacted the witch who created the Hybrid Curse, Klaus realized that the Original witch had been playing him. A short time later, Klaus assumed that the original witch would never help him and gave Tyler Lockwood Elena's blood as a hunch when he awoke in transition, because even if it didn't work, he'd die without a successful transition anyway. Klaus' hunch ended up being correct, and Tyler then became Klaus' first successful hybrid since Klaus broke his own Hybrid Curse.

Afterward, Klaus revealed that the Original witch who cursed Klaus had a fail safe - the doppelgänger had to die in the ritual to turn Klaus, but her blood was needed to turn any hybrids he tried to make. This was put in place in order to avoid the creation of new hybrids if Klaus were to ever break the curse. Klaus believes it was done as the Original witch (who was later revealed to be his own mother, Esther Mikaelson) hated him.

Klaus can still turn humans into vampires, as can his hybrid progeny. Before it was revealed that Klaus' child can make hybrids, every previous hybrid has been directly created by Klaus.

It has also been revealed that Klaus, as a werewolf who was turned into a hybrid with magic rather than by hybrid blood, can have children thanks to his werewolf side. Additionally, Klaus' child's mother, Hayley Marshall was a full blooded werewolf at the time of the child's conception, and her father is the original hybrid, so the child, Hope Mikaelson, is a witch-werewolf-vampire tribrid, having inherited the ability to practice witchcraft from her paternal grandmother Esther, her werewolf gene from both her parents, and vampire heritage from her father. Immediately after Hope's birth, Hayley was killed, but because Hope's blood was still in her system, she reawakened in transition, and eventually drank another drop of Hope's blood to complete her transition to stay in her life.

It has been proven that tribrid blood is a powerful binding agent similar to doppelgänger blood. This eliminates the need of doppelgänger blood during transition, though only the tribrid's blood can finish the transition of a new hybrid, thus the hybrid race still depends on a single and rare supernatural creature.

## History

### The Original Hybrid

The first hybrid, Klaus, was conceived when his mother Esther had an affair with the Alpha of their village's werewolf pack, Ansel. Her affair was kept a secret from everyone, as well as Klaus' werewolf heritage. However, when Klaus made his first human kill after being turned into a vampire, he triggered his werewolf gene, which turned him into a the world's first hybrid and revealed that he was the illegitimate child of the Alpha of the same pack whose member was guilty of killing Esther and Mikael's son, Henrik.

When Mikael, Klaus' step-father, learned about his wife's infidelity, he set out and killed Ansel and his whole family, which began the feud between vampires and werewolves which has been perpetuated across the ages and, to some extent, to this day. Being a hybrid, Klaus has additional powers that his siblings and father do not. However, Esther, the Original witch, cast a spell on him to suppress his werewolf side and prevent him from accessing the powers that came with his father's heritage, both as a duty to Nature (to balance his powers) as well as a way of atoning for her affair. She bound the curse with the blood of the Tatia, the first Petrova doppelgänger, and the moonstone, and then turned her back on him, a move that resulted in her violent murder at Klaus' hands.

In 15th century England, Klaus, now a nobleman in England, along with his brother Elijah, came across Katerina Petrova, later to be known as Katherine Pierce, a Petrova doppelgänger who had recently relocated after being banished from Bulgaria. When he recognized her as being the doppelgänger of Tatia, Klaus wooed her while secretly planning to use her to break the curse. However, upon learning the truth behind Klaus' desire for her, Katerina stole the moonstone and fled with help from Trevor, and ended up tricking Rose-Marie into turning her into a vampire, which put a damper on Klaus' plans to break the curse for over 500 years. In order to get back both the Petrova doppelgänger and the moonstone as soon as possible, Klaus spread a false rumor about a supposed "The Sun and Moon Curse" which limited the vampires' and werewolves' powers. In so doing, he set both vampires and werewolves, two warring species, into searching for a Petrova doppelgänger and the moonstone, knowing that any news of their discovery would eventually come back to him.

In 2010, Klaus enlisted a witch called Greta Martin to break the curse by sacrificing Jules, the werewolf, Jenna Sommers, who had been turned into a vampire, and Elena Gilbert, the Petrova doppelgänger. He succeeded in breaking the curse, but as he was in transition, Bonnie Bennett, a witch who had harnessed the power of a hundred dead witches, attacked Klaus with the force of nature and pushed him to the brink of death. Klaus' older brother, Elijah, attempted to kill him for having daggered and disposed of their family, but Klaus revealed that the bodies of their siblings were safe and that he could take him to them. Elijah helped Klaus escape, despite Bonnie's threat to kill them both even if it meant death herself. Klaus completed the transition and turned into a wolf for two days, killing many and remembering the kills. He later noticed that the fact that he had stayed a wolf after the full moon meant he could change into wolf form at will.

Klaus is more powerful than any other hybrid both because he is an Original vampire with over 1,000 years of experience as well as being able to turn into a wolf and kill any vampire with a single venomous bite. The difference between him and his pure vampire siblings are that Klaus cannot be neutralized by the dagger coated in white oak ash. Also important, unlike other hybrids or vampires, Klaus can also compel other vampires and hybrids. Klaus' blood is also the only thing that can cure a vampire from a werewolf bite's venom, as shown when he saved Damon in exchange for Stefan's loyalty.

### A New Species

Klaus wanted to become a hybrid in order to create his own species, to be used as soldiers that would aid him in anything he would face; in his words, "You don't build an army when war has been declared. You create an army so large that no one dare pick a fight." However, in truth, he really wanted a new family, one that was obedient and loyal to him, unlike his own siblings, who he alienated out of fear that he was unloved. Klaus brought Stefan, who he had coerced into being his right hand man by curing Damon of his werewolf bite and bringing back his blood-lust by forcing him to gorge on human blood for the first time in centuries. Klaus and Stefan traveled all around the country in pursuit of werewolves who Klaus could turn into hybrids. They found Ray Sutton, a werewolf and caught up with him at a bar, where they tortured him until he admitted the location of his werewolf pack. Klaus fed Ray his blood before killing him, beginning his transition from a werewolf to a hybrid. From there, Klaus had Ray bring him and Stefan to a werewolf pack in the mountains. He fed and killed all of those werewolves as well but as he did, all of them, including Ray, showed strange symptoms. They'd turn pale and sickly and feel sick, their eyes bleeding all of which Klaus had thought would fade away quickly but they did not. This turned all of them rabid and feral, so Klaus had to kill every last one of them, hugely disappointed by the failure of his hybrids. He traveled to Chicago to meet an old witch friend, trying to figure out what went wrong. When he learned that Elena, one of the sacrifices to unleash his dormant werewolf side, ended up living through the ordeal, he was furious about being tricked and though he, Stefan and Klaus' sister Rebekah assumed it was because she was still alive that Klaus couldn't mass produce hybrids, Klaus wanted to be sure before he took action.

He realized the Original Witch, his mother, had planned that if he did manage to break the curse on his body, then the Doppelgänger would have to die, so Klaus realized this was another trap by his mother and decided to do the opposite of the obvious. Instead, he decided Elena being alive was essential and that it was her Doppelgänger blood hybrids had to drink to survive the transition. With this hypothesis, Klaus turned Tyler Lockwood into a hybrid and with the help of Elena's blood, Tyler survived the transition and became the first successful hybrid. Successful hybrids had a built in sire bond to Klaus, feeling loyal and thankful to him for releasing them from the torment of having to transform on every full moon.

His victory was short lived, though. When Klaus heard rumors that his father, Mikael, was back and searching for him again, he fled. However, he took his time away from Mystic Falls to continue to build his power, turning packs of werewolves into hybrids with bags of Elena's blood he had managed to get before leaving. On these trips, he turned two of his most trusted hybrid lieutenants, Tony and Mindy, bringing all of his hybrids back to Mystic Falls when he heard that his father had been daggered by Elena. Throwing a party at Tyler's house, with all his hybrids as his backup, Klaus celebrated his father's daggering only to discover it was a trap. He expected as much, however, telling his hybrids that if anyone tried anything to hurt him, to tear that person apart. Mikael himself appeared having been able to use his compulsion on Mindy since she was still half vampire. Mikael threatened Klaus, telling him he was a coward to hide behind his hybrids. Mikael threatened to kill Elena if he didn't come outside, and Klaus called his bluff, so Mikael stabbed her. While Klaus was stunned at Elena bleeding out, Damon took that opportunity to try to stake Klaus to death, but misses his heart. Katherine revealed herself, having been posing as Elena, and she attacked the group of Klaus' hybrids with wolfsbane grenades to give Damon more time to kill Klaus. However, Stefan saved Klaus and giving him the opportunity to kill Mikael, knowing that the hybrids would kill Damon if he succeeded in killing Klaus. In thanks, Klaus freed Stefan from being compelled to serve him. Stefan, appreciative of being released from his control, took revenge by stealing the coffins that contained his siblings, including a locked coffin that couldn't be opened.

The loss of his family's bodies made Klaus tighten his grip on Mystic Falls even more, deciding he wanted to settle there, in the place where he lived a thousand years before. His hybrids quickly began building a large mansion for his new home, which he hoped his family would soon live in as well. More than anything, he wanted his family back and was willing to hurt people if he didn't get his way. Tony, Klaus' right hand man, stalked Elena and after a scheme that nearly killed both her brother and Alaric Saltzman, Tony was beheaded and killed by Jeremy Gilbert. Klaus sped up his search for his family, having his hybrids search all over town, one of them being killed by Stefan and Damon when he was close to discovering the coffins' location at the old witch house. Stefan decided he had to hit Klaus back hard for what he did, so after ordering Klaus to pack up and leave, he killed Mindy to show he was serious. Daniel Warren became Klaus' new favored hybrid, being there when Klaus was making his power play and solidifying himself into Mystic Falls by promising Mayor Lockwood that the hybrids would protect the town. Stefan complicated things, though, attempting to kill Daniel but was interrupted by Damon who saw the futility of killing all the hybrids, knowing it would only make Klaus even angrier.

Klaus then trusted Daniel Warren with an important task again, sending him off to threaten Bonnie's newly discovered mother, Abby Bennett Wilson, and when a deal was finally reached that involved the Salvatore's turning over his three brothers' coffins, Klaus seemed victorious. However, while standing by the coffins, saying that he'd un-dagger them once Stefan was out of the way, Daniel's heart was suddenly ripped out by Elijah, who had been un-daggered by Damon before being returned to Klaus. Elijah un-daggered the rest of the family and Klaus seemed to put his family first, focusing on them over his hybrids for a brief time.

### A Sire Bon

Having been sired by Klaus, like all the other hybrids, Tyler felt instinctively loyal to him. He would do whatever Klaus asked without a second thought, even helping in nearly killing Jeremy during the struggle over the Originals' coffins. Klaus had also ordered Tyler to bite Caroline Forbes, Tyler's own girlfriend, which would be lethal to her and when Tyler refused, it seemed he had finally thought for himself. However, the sire bond made him unwittingly bite her anyway the first moment he had a chance, showing that he truly had no free will anymore. This showed Tyler that being a hybrid really had its pitfalls, and after a lesson in trying to overcome the sire bond from Caroline's dad, fled town to try and figure out how to break it. He went out to the mountains where he transformed into a werewolf over and over, a hundred times, breaking all of his bones, because once he could own his pain, he would no longer owe Klaus for ending the misery of turning at every full moon. He had help from a young werewolf girl named Hayley and after months of self-torture and teaching himself control, Tyler felt comfortable enough to go home.

Tyler returned to Mystic Falls, telling Caroline that he believed that he was finally free from Klaus' sire bond but he couldn't be sure until he tested it out. Caroline told him to lay low as it was too risky and if Klaus found out the bond was broken, he'd no doubt kill him. Tyler disobeyed her after learning Klaus had shown romantic interest in her. He went to the school's 20s Decade Dance where he realized first hand that he no longer had to do what Klaus said, but kept up the illusion that he was still sired. He dropped the charade, however, when Elena was captured by Klaus who was trying to flee town since Alaric Saltzman had been transformed by Esther into a vampire with a White Oak Stake that could kill him. Tyler tried to free Elena, disobeying Klaus' direct orders but was caught by Klaus who tried to kill him since he was no longer loyal. Tyler fought back though and with the help of the Salvatore's and Bonnie's magic, they managed to desiccate Klaus' body, draining it of all of his blood and neutralizing him.

They planned on dropping his body in the ocean and being rid of him which overjoyed Tyler. However, when Alaric pursued them, wanting to fulfill Esther's plan of killing the Originals. They knew that since Klaus sired their vampire bloodline, that they would all die if Klaus died, and they knew that Alaric would go after Klaus first now that he was neutralized, so with their lives at risk, Bonnie performed a spell to transfer Klaus' soul into Tyler's body. This saved Klaus even when Rick staked him with the white oak stake. He remained in Tyler's body for a brief period before Bonnie returned him to his charred but healing original body.

### The Revolution

Shockingly to all, Elena had been killed by Klaus's sister Rebekah, with vampire blood in her system, turning her into a vampire. This made her blood useless to use in turning werewolves into hybrids so Klaus was forced to rely on the three blood packs he had left when he tried to kill her by draining her blood. Rebekah crushed these packs, though, in a fit of anger after learning Klaus wasn't actually dead, and feeling betrayed because he chose to save Caroline over her. She accused her brother of trying to replace his real family with his hybrids, when he had her this whole time. This made it impossible for Klaus to make anymore hybrids, and in his own fit of anger, disowned Rebekah as his sister and snapped her neck.

After a new vampire hunter came to town and had tried to kill Tyler, Klaus ordered a few of his remaining hybrids to protect Tyler, citing that since hybrids were an endangered species now, he didn't want any more to die. Klaus learned that this new hunter, Connor Jordan, was a member of the Brotherhood of The Five and that this group of hunters was the key to finding a cure for vampirism. This cure gave him hope that he'd be able to return Elena to being a human and use her blood to fuel his hybrids once more. He took Connor captive, interrogating him for information and compelling Jeremy, who was the only one to see his Hunter's Mark, to sketch it, as the tattoo was a map to the cure. The tattoo grows with every vampire killed, so at the time it was only a partial map.

After receiving a vague sketch from Jeremy, Klaus had one of his hybrids, Nate, watch over Connor to make sure he didn't escape. Connor did just that, though, using his chains to rip off Nate's head, killing him. He brought Nate's head back to his trailer, where he extracted Werewolf Venom from his mouth to use against the other vampires he wanted to hunt. With Connor out on the loose and Klaus flying off to Italy to find a sword that would help find the cure, he sent one of his most trusted hybrids, Dean, to capture Connor alive. Hayley, the werewolf who had helped Tyler break his sire bond found him in Mystic Falls and together, they plotted to help free the other hybrids from their sire bonds.

They tried to convince Dean that he shouldn't go after Connor, knowing it might mean death but his loyalty to Klaus made him go anyway. Connor had taken hostages at the Mystic Grill so Dean tracked him down there, entering the building cautiously. However, Connor had set up a trip mine that was connected to an explosive containing a lot of nails. Dean set off the trap, being caught in the explosion and pierced by dozens of the nails all over his body. Disoriented and wounded from the blast, Dean crawled up to his knees only to find Connor waiting for him, blowing a hole in his chest with gun, shooting out his heart and killing the hybrid, much to Tyler and Hayley's sadness and disappointment.

Despite Dean's death, Tyler and Hayley continued their efforts to free their hybrid friends. They would bring them to isolated areas and have them transform into their wolf forms repeatedly, dissipating the appreciation hybrids had for Klaus freeing them from their werewolf curse. They managed to free a hybrid, Chris, who helped them when Elena was suffering from the Hunter's Curse after she had killed Connor. However, when Chris was panicking, wanting to leave since he knew he'd die if Klaus found out he was no longer sired, Jeremy Gilbert arrived and killed Chris in order to activate his membership into The Five and save Elena from the Hunter's Curse.

This infuriated Tyler, upset that his high school friends would so ruthlessly murder one of the hybrids, especially one who was no longer loyal to Klaus. Tyler and Hayley continued their efforts, breaking the sire bond of twelve other hybrids, including Kimberley and Adrian. However, once there was no longer any loyalty to Klaus, their werewolf instincts made it so there had to be an alpha of the pack, a leader. Kimberley made her bid to lead, kidnapping Tyler's friends but Tyler nearly ripped her heart out, telling them all that he was the alpha and that he would offer them retribution for Klaus' crimes. They all followed Tyler, accepting them as their leader and his plan to rebel against Klaus began.

Tyler's plan came to fruition during the Winter Wonderland party the town was throwing. The plan was that the hybrids would all ambush Klaus and using the body jumping spell Klaus had always favored, and had used to possess Tyler a few months prior, have Bonnie plant Klaus' soul back into Tyler's body. They'd then bury Tyler's body in concrete, but only so long that the now freed hybrids would have a chance to scatter to the far reaches of the planet, far from the master they had betrayed. Despite his friends and mother not wanting him to go through with it, Tyler was adamant that it was necessary for his friends' survival. Good news arose, when Caroline and Bonnie brought up that they could put Klaus into Rebekah's daggered body instead, not needing to use Tyler.

This made Tyler extremely happy but little did he know, his partner-in-crime, Hayley, had her own plans. She had been working with Atticus Shane, to help him complete the three sacrifices that he needed in order to create enough energy to fuel his plan to awaken the ancient immortal, Silas. Shane had promised her that Silas would be able to bring back her parents from the dead so Hayley agreed to help him gather twelve lives to kill in the second sacrifice(the first being the Town Council). She had Tyler gather all of the hybrids in one place but then, unknown to Tyler, told Klaus that his hybrids were no longer sired. Klaus, infuriated by the news, found the twelve un-sired hybrids in the woods.

He started by ripping out Adrian's heart before unleashing his wrath on his former pack, using his sword to behead and impale them. Kimberley managed to escape to the Lockwood cellar but Klaus followed her, realizing this failed attempt at a coup was Tyler's doing. He asked her where Tyler was but she tearfully told him she didn't know. He cut off her head, shattered by knowing that he now had no more loyal hybrids. He had stopped the uprising that Tyler had sparked but the cost of losing his followers made him want nothing more than to see Tyler dead. In retaliation he murdered Tyler's mother while Tyler discovered the bodies of all of his friends. Soon after, he found his mom's body as well, realizing his revolution had crumbled and Klaus had won, leaving the two of them as the only hybrids left on the planet.

### The New Generation

Tyler was emotionally drained from the loss of his mother and pack at the hands of Klaus. Luckily for him, Klaus was too busy trying to find the cure to bother finishing off Tyler. However, after Elena and Jeremy had killed Klaus' brother, Kol, and Bonnie had trapped Klaus in the Gilbert House, Tyler came face to face with his mother's murderer again. Gloating about the fact that his friends would get the cure and bring it back so he could shove it down Klaus' throat and kill him, Tyler was confident that Klaus' bloodline would be gone once he cured him, so there was no risk of dying when he killed Klaus. However Tyler was simply Making a mockery of Klaus, and he does not have any physical evidence, to back up this statement.

A new hope came for the hybrid race when it was revealed that they can have children with werewolves as Klaus impregnated the werewolf Hayley and now she is carrying his child. It was confirmed by witches that Klaus was the father through a spell one of them cast. This child is probably one of Klaus' only ways of making more hybrids until he obtains Katherine's blood. It is unknown if Klaus can have children, with humans, or witches, or if non-Original male hybrids can have children, with werewolves, humans, or witches.

When Tyler came New Orleans for revenge against Klaus for what he had done to him, he began by kidnapping Hayley and tested a theory if the baby's blood could be used to turn hybrids it worked and he believed that Klaus would use the baby to sire more hybrids. With the tool of his revenge in front of him, he attempted to kill Hayley, but she escaped and Klaus arrived. There was a face off between the two hybrid and Klaus emerged as the winner. He didn't kill Tyler, but let him live in return so Tyler could still suffer even more now that he has failed.

In *Dance Back from the Grave*, the baby is revealed to have inherited witch abilities from Klaus, due to his mother, Esther.

In *From a Cradle to a Grave*, the baby is born and her mother is killed mere seconds afterwards. However, due to the baby's blood in her system, she wakes in transition. Later, Hayley drinks a drop of her baby's blood so that she can complete the transition, becoming the first Hybrid of the new generation.

In *Home*, Tyler is stripped of his vampirism by the Travelers, leading to his death. After his resurrection, he is no longer a hybrid because he died as a werewolf. This leaves Klaus, Hayley and Hope as the last remaining hybrids in the world.

### Aberrations of Nature

The first witch-vampire hybrids, were originally a subset of mutated witches known as Siphoners. Considered to be unnatural for their ability to steal magic from other supernatural species (witches, vampires, werewolves, etc) or magical objects, they were cast out of their Coven. The original six then became known as the Heretics, making their way to Europe, where they eventually met Lillian Salvatore. Lily had been massacring several thousand people in Europe in the years after she turned in 1858. After meeting Lily, a Ripper vampire, and her lover Julian, they quickly became close friends and a family.

Sometime later with a fallen out with Julian, Valerie dies with Lily's blood in her system. Valerie recounts that she drew herself a bath, laced her tea with laudanum, and went quietly to sleep (possibly drowning as well), then by virtue of pure happenstance, she became the first Heretic both witch and vampire. Lily would eventually turn the rest into vampires so they could remain together forever as a family. However, because their unusual Siphoner abilities had not been accounted for during the creation of Nature's laws, the Heretics quickly found that, as vampires, they could not only still siphon magic from other objects and beings, they could also siphon the magic that made them immortal and use it as a power source. They even found that their siphoning abilities could allow them to cure themselves of the deadly werewolf venom (which would be fatal to any ordinary vampire who was unable to ingest Klaus' blood as a cure) by siphoning the magical basis of the werewolf venom.

## Powers and Abilities

### Werewolf-Vampire

Non-Original werewolf-vampire hybrids have the powers and abilities of both werewolves and non-Original vampires, both physically enhanced powers and abilities of mind compulsion. Non-Original werewolf-vampire hybrids will grow stronger with age due to their vampirism and will also increase in strength when enraged, due to their werewolf side. Their strength will also increase during a full moon.

* **Super Strength:** Non-Original werewolf-vampire hybrids are stronger than Werewolves, Evolved Werewolves, non-Original Vampires, Supernatural Hunters, Immortals and Humans. Due to their vampire side, they also get stronger with age. The full moon will boost their strength and aggression. Older non-Original vampires may be stronger and more challenging for many newborn non-Original werewolf-vampire hybrids. However, if a non-Original werewolf-vampire hybrid fights a non-Original vampire closer to their age range, the non-Original werewolf-vampire hybrid will win. Ray Sutton (a dying transitioning, unsuccessful non-Original werewolf-vampire hybrid) was shown to be very strong and nearly killed Damon, a non-Original vampire more than 170 years old, until Stefan saved him. Non-Original werewolf-vampire hybrids are even capable of putting up a fight against non-Original vampires well above their age range as seen when Tyler was able to gain the upper hand and bite Nadia, a 500 year old non-Original vampire. It should be noted that Nadia did manage to overpower Tyler eventually and escape, implying that she had equal or slightly superior strength. Julian, while possessing Tyler's body, was able to fend off both Caroline and Stefan and even managed to kill the latter through heart extraction. A non-Original werewolf-vampire hybrid in werewolf-form will be immensely powerful and may be a slight challenge for even an original vampire.
* **Super Speed:** A non-Original werewolf-vampire hybrid's intensified quickness, agility, reflexes, and endurance makes them faster than any werewolves, evolved werewolves, non-Original vampires, supernatural hunters, immortals and humans. Non-Original werewolf-vampire hybrids can use this ability in human or werewolf form. As with strength, non-Original werewolf-vampire hybrids get faster with time. The full moon will increases their speed and being in werewolf form will make them even faster. Tyler was particularly fast as a non-Original werewolf-vampire hybrid, being fast enough to surprise Klaus and stake him.

* **Super Agility:** Non-Original werewolf-vampire hybrids possesses much more superhuman stamina, flexibility, reflexes, agility and dexterity than immortals, non-Original vampires, werewolves, evolved werewolves and humans. They can move, jump, climb, and run incredibly fast without difficulty or exhaustion.

* **Super Senses:** Non-Original werewolf-vampire hybrids have extremely keen senses of hearing, sight, touch, and smell that exceed those of non-Original vampires, werewolves, evolved werewolves, and humans. Since they're a supernatural crossbreed between werewolves and non-Original vampires, non-Original werewolf-vampire hybrids have the combined senses of both species thus making their ability extremely effective, Tyler Lockwood has been seen to use his super senses on multiple occasions such as when he overheard Katherine (in Elena's body) say that Caroline slept with Klaus or when he was able to hear Nadia compelling Matt but a prime example of this ability is in "Home", when Tyler is resurrected and hugs Caroline but then he tells her that it felt different, because he was no longer a non-Original werewolf-vampire hybrid.

* **Super Durability:** Non-Original werewolf-vampire hybrids can bear a lot of trauma. They also hardly ever get tired or fatigued. Non-Original werewolf-vampire hybrids can take far more trauma than any non-Original vampires, werewolves, evolved werewolves and humans, without much discomfort or injury. Stakes and arrows can not kill a non-Original werewolf-vampire hybrid when they are struck in the heart, they merely become unconscious, they are able to resist the bullets created by The Brotherhood better than non-Original vampires as Stefan said to Tyler, that if he was a normal vampire he would be dead.
* **Enhanced Healing Factor:** Non-Original werewolf-vampire hybrids have the combined healing capabilities of both non-Original vampires and werewolves, rendering them practically invincible to anything but fatal wounds that can seriously impair their healing capabilities like decapitation or heart-extraction. They can recover/heal/regenerate from any injury much quicker and more effectively than any non-Original vampires, werewolves, evolved werewolves and humans. They also seems to heal much more quickly when exposed to vervain, wolfsbane, or wood. Human blood has also known to make the healing process faster.
* **Immortality:** Non-Original werewolf-vampire hybrids stops aging the moment they transition. They become immune to all conventional diseases, toxins, poisons, viruses, illness, infections, and injuries.
* **Day Walking:** Due to their werewolf heritage, non-Original werewolf-vampire hybrids are immune to the lethal effects that u.v. rays and sunlight have on non-Original vampires and original vampires. Allowing them to walk in daylight without the use of a day ring.
* **Emotional Control:** Due to their vampire heritage, non-Original werewolf-vampire hybrids are able to exert certain control over their own emotions, e.g. They can turn off their humanity.
* **Enhanced Emotions:** Because of their vampiric and werewolf traits, non-Original werewolf-vampire hybrids experience emotions more powerfully than humans and non-Original vampires. Particularly emotions such as anger, rage, aggression and violence due to their werewolf heritage. Non-Original werewolf-vampire hybrids are more prone to violence and rage than non-Original vampires. However, emotions such as love, joy, and happiness are intensified for them as well, allowing them to live life more intensely. This ability allows them to feel emotions at their peak regardless of their age.

* **Lycanthrope Enhancement:** Non-Original werewolf-vampire hybrids are capable of using their werewolf features to further supplement their powers and abilities. Non-Original werewolf-vampire hybrids can grow claws from their nails and werewolf fangs from their teeth even when they are still in their human forms. When Klaus was in Tyler's body, it was shown that a non-Original werewolf-vampire hybrid's claws are sharp enough to penetrate a non-Original werewolf-vampire hybrid's very durable skin. Also non-Original werewolf-vampire hybrids can display both sets of vampire and werewolf fangs. Their eyes also change into those of their werewolf form, presumably granting them better eyesight. Due to their werewolf heritage, a non-Original werewolf-vampire hybrid's strength and speed are heightened further during a full moon and at its peak in their werewolf forms.

* **Mind Compulsion:** A non-Original werewolf-vampire hybrid can compel the minds of Humans. They cannot, however, compel original vampires, non-Original vampires, Supernatural Hunters, Witches or Werewolves.

* **Shapeshifting**/**Transformation Control:** Non-Original werewolf-vampire hybrids have the ability to transform into their werewolf forms at will. Most of them avoid transforming at all due to the pain it causes. They have complete awareness, but they still, however, have no control of their actions in werewolf form. They can also perform partial transformations, manifesting single features of their werewolf forms. Elijah informs Klaus that he remained a werewolf for two days, even when the sun was up. Showing that a non-Original werewolf-vampire hybrid can stay in werewolf form longer than a normal werewolf. As seen with Klaus when he bit Katherine, a non-Original werewolf-vampire hybrid can transform partially, displaying their werewolf eyes and teeth.

* **Sire Bond:** Non-Original werewolf-vampire hybrids seem to be sired to the source of their creation. Non-Original werewolf-vampire hybrids turned by Klaus had a deep sense of gratitude and commitment to him causing them to obey his every command. When Hope Mikaelson's blood was used to turn a werewolf into a non-Original werewolf-vampire hybrid it obeyed Hayley's plea for help as she was still pregnant with Hope and in danger. It is later revealed that Hope's blood like Klaus' carries a powerful sire bond effect causing any non-Original werewolf-vampire hybrid created from her blood to protect and obey her. A non-Original werewolf-vampire hybrid is capable of breaking a sire bond, if they transforms into their werewolf forms an excess of 100 times in a row. Transforming so many times in a row causes them to no longer feel pain from transforming into a werewolf and they no longer feel a sense of gratitude, commitment or loyalty to their creator breaking the sire bond. Like non-Original vampires/original vampires, non-Original werewolf-vampire hybrids can form a sire bond if the human they turn into a vampire has feelings for them before being turned. Although like non-Original vampires/original vampires, this is extremely rare.
* **Telepathy:** Non-Original werewolf-vampire hybrids have the ability, albeit a weak variant, to enter the minds of others as long as theirs is stronger than them. Normally, this ability works in a tactile fashion and the non-Original werewolf-vampire hybrid requires physical contact in order for it to work successfully. Hayley have also been shown sharing her memories with others. Like their physical attributes, their mental strength increases with age.
	+ **Dream Manipulation:** Non-Original werewolf-vampire hybrids can control dreams and subconscious like non-Original vampires/original vampires. They can produce and modify dreams, bestow nightmares or lucid dreaming. Other effects of this ability is the distortion of reality and trapped in the dreams.
	+ **Illusions:** Non-Original werewolf-vampire hybrids have the power to trick the minds of others into seeing/feeling things that aren't actually happening.
* **Werewolf Bite:** Due to their werewolf heritage, non-Original werewolf-vampire hybrids and Klaus have venom which is fatal to non-Original vampires and they themselves are immune to werewolf venom. Non-Original werewolf-vampire hybrid venom seem to take effect much faster than a normal werewolf venom.
* **Immunity to Silver:** Due to their werewolf heritage, magic bonded to silver doesn't affect non-Original werewolf-vampire hybrids. Weapons made of silver might wound them, but the wound heals at super-normal rates than regular wounds.

### Witch-Vampire

A hybridization of a witch and a vampire has long been thought to be impossible. However, a subsection of mutated witches with the ability to siphon magic known as Siphoners have shown to bypass this rule. A group known as the Heretics consists of these hybrids.

They always have the advantage of superior strength in direct combat with a human. Their other feats include single-handedly lifting grown men high off the ground by the throat and snapping their necks, cutting off a person's head with their bare hands, and ripping out internal organs such as hearts with little to no effort. Their strength is also more powerful than that of Werewolves and Evolved Werewolves in human form. Their strength allows them to jump higher and further than any natural creature.
* **Super Speed:** Non-Original witch-vampire hybrids possess the same speed as non-Original vampires; able to accelerate their movements to cover short distances in an instant, faster than the human eye can see. When running across long distances, they appear as vibrating blurs of motion. Their reflexes are similarly heightened. Like their strength, their speed increases with age.
* **Super Agility:** Non-Original witch-vampire hybrids possess superhuman agility. They have shown that they can move, jump very high, climb, and run incredibly fast without difficulty or exhaustion. They can jump with their super speed too. These abilities increase with age.
* **Super Senses:** Non-Original witch-vampire hybrids possess extremely keen senses of hearing, sight and smell that far exceed those of humans and werewolves.
* **Super Durability:** Non-Original witch-vampire hybrids can take a great amount of physical damage without being slowed down.

* **Healing Factor:** Non-Original witch-vampire hybrids possess the ability to recover tissue from any form of physical damage to their bodies in seconds, but still feel the pain of a wound before it heals. Vampires can snap their bones back into place after being broken and have been seen to fully recover from gunshots, stab wounds, and torso impalement.
* **Immortality:** Non-Original witch-vampire hybrids stop aging once turned. Upon their transformation, they become immune to all conventional illness, diseases, viruses and infections, though the exception is cancer, which can only be exacerbated by vampirism.

* **Day Walking:** Due to their Siphoner heritage, non-Original witch-vampire hybrids are be immune to the lethal effects that u.v. rays and sunlight have on non-Original vampires and original vampires. Allowing them to walk in daylight without the use of a daylight ring.
* **Enhanced Emotions:** Non-Original witch-vampire hybrids experience emotions more powerfully than humans. Emotions like love, joy, and happiness are magnified for vampires, allowing them to live life more intensely.
* **Emotional Control:** Non-Original witch-vampire hybrids have the supernatural ability to remove or dull their emotions by "turning off" or "switching off" their humanity which is directly connected to their emotions. Doing so allows them to block out their more negative emotions, such as fear and guilt, allowing them to feed and kill without remorse.

* **Mind Compulsion:** Non-Original witch-vampire hybrids have the ability to influence and control thoughts, emotions, and behavior and can alter or erase memories.
* **Sire Bond:** Although rare among them, sire bonds can be formed when a human is turned with the blood of the vampire whom they had strong human feelings for.
* **Telepathy:** Non-Original witch-vampire hybrids have the ability, albeit a weak variant, to enter the minds of others as long as theirs is stronger than them. Normally, this ability works in a tactile fashion and the vampire requires physical contact in order for it to work successfully.

When their true face is revealed, the sclera of their eyes turns blood-red, dark veins appear under their eyes as the blood pumps forcefully through them, and their canine teeth extend into razor-sharp fangs. Their true face can be revealed whenever they wish, but it will appear against their will whenever they are aroused by the scent of blood, or are feeling intense emotions such as anger, lust, sadness, etc. Their fangs are extremely sharp which gives them the ability to tear into almost any substance (including and especially flesh) and tear off limbs. Their true face will appear for the first time, either while they drink human blood for the first time or shortly afterward. With the fangs come the darkened veins under the eyes as well.

### Witch-Werewolf

Niklaus Mikaelson and Millicent Lockwood are the only two known witch-werewolf hybrids known throughout the franchise, though Klaus was untapped prior to becoming an original vampire, later the Original hybrid.

* **Channeling:** Witch-werewolf hybrids have the power to invoke extra forms of energy by focusing on external forces.
* **Potion Brewing:** Witch-werewolf hybrids have the power to brew and concoct potions, remedies and elixirs that have supernatural properties.
* **Spell Casting:** Witch-werewolf hybrids have the power to change and control events through the use of incantations and more.
* **Divination:** Witch-werewolf hybrids have the power to divine future, past, and present events based off extrasensory perception.
* **Super Strength:** Witch-werewolf hybrids have the same strength as werewolves and are noticeably much stronger than Supernatural Hunters, Immortals and Humans. There have been several occasions to suggest that untriggered werewolves possess more strength than any average humans, which would indicate some form of enhanced strength even before the activation of their curse. However, werewolves in their human form are not as strong as a vampire, and have been shown to be far weaker. When they are in their wolf form, their powers amplify to a degree that excels that of the non-Original vampires, making them more powerful than non-Original vampires. In wolf form, a werewolf can overpower and kill any non-Original vampire with ease, and can also defeat an Original Vampire in small groups.
* **Super Speed:** Witch-werewolf hybrids possess the same speed as werewolves; they possess this ability both in and out of transformation with an animalistic quickness; however, the power is faster at night than in the day, due to the moon's presence, and their speed increases greatly when the werewolf is transformed during the full moon. In wolf form, however, while under the influence of the full moon, they can use their speed to swiftly chase down their choice of prey; even vampires.
* **Super Durability:** Witch-werewolf hybrids can take far more trauma than humans without nearly as much discomfort or injury, however, not as much as vampires. They can also exert themselves for longer periods without tiring.
* **Healing Factor:** Witch-werewolf hybrids possess superhuman regenerative abilities, meaning that if they are physically injured, their bodies will heal rapidly. Like Vampires, werewolves can heal from the most grievous of injuries, even in human form, albeit more slowly in comparison to vampires. However, unlike vampires, when a werewolf’s neck is broken, they stay dead.
* **Super Senses:** Witch-werewolf hybrids have the extremely keen and heightened senses of smell, sight, taste, hearing and touch inherent in all canines. Because they are supernatural and have powers that exceeds their wolf counterparts, they can hear, see, and smell better than that of regular canines.
* **Lycanthrope Enhancement:** Witch-werewolf hybrids are able to make their eyes glow when angry or threatened, but only for a short amount of time. When a werewolf is furious or forced to defend themselves, their anger increases all their power and abilities for a short period of time, which allows them to access some of their powers to give them an edge.
* **Shapeshifting**/**Transformation Control:** During a full moon, they will unwillingly transform from their human forms and into their wolf forms. However, if a female witch-werewolf hybrid is pregnant, they will not turn for nine months as the transformation would kill the baby.
* **Werewolf Bite:** A witch-werewolf hybrid's venom is extremely lethal to non-Original vampires. While an Original vampire cannot die from the venom, they are not wholly immune to the effects of the venom. For non-Original vampires, the venom acts as an poison of sorts that will enter the bloodstream and deliver the toxin throughout the body, producing discomfort and weakness. All vampires who are bitten will ultimately develop uncontrollable hunger that progresses to delusions, hallucinations, rabid rage, and dementia. After that point, non-Original vampires will finally die, though many are "mercy-killed" before that point.
* **Full Moon:** A witch-werewolf hybrid's strength, speed, agility, and all their powers are enhanced to their peak during a full moon.
* **Immunity to Silver:** Witch-werewolf hybrids are immune to magic bonded to silver. Weapons made of silver might wound them, but the wound still heals at supernatural rates and will not be fatal to them.

### Original Hybrid

Klaus has the powers and abilities of both werewolves and original vampires, both physically enhanced powers and abilities of mind compulsion. Klaus will grow stronger and faster when he is using his lycanthrope enhancement due to his werewolf side. His strength and speed will also increase during a full moon. Klaus is slightly more physically powerful than his maternal half-siblings, even more so when enraged, using his lycanthrope enhancements or when he is in his werewolf form; due to his werewolf heritage.

* **Super Strength:** Klaus is much stronger than immortals, Supernatural Hunters, non-Original vampires, werewolves, Evolved werewolves, non-Original werewolf-vampire hybrids and humans. He is able to decapitate other species with a single chop and shatter windows and doors with small objects. He is even slightly physically superior to the Original vampires, even more so when enraged, using his lycanthrope enhancements or when he is in his werewolf form, due to his werewolf heritage; Elijah and Kol have displayed the ability to fight Klaus on almost equal terms, though not enough to defeat him. Elijah has been able to fight Klaus to a stalemate and has even defeated him once, while Rebekah has been easily subdued, though unlike Elijah, Rebekah very rarely fights back. Klaus' strength is enough that he could kill twelve non-Original werewolf-vampire hybrids single-handedly, and was able to fight and kill twenty four non-Original vampires on his own with only some difficulty as well as kill six evolved werewolves with little difficulty. Klaus has also been able to put up more of a fight against beings who have overpowered his siblings in strength, such as holding Alaric to a standstill over the White Oak Stake when he had become an Enhanced Original vampire whereas Rebekah was easily overpowered. In *The Devil Comes Here and Sighs* and in *Where Nothing Stays Buried*, Lucien, an Upgraded Original vampire, was proved to be much stronger than Klaus in their confrontations.
* **Super Speed:** Klaus' intensified quickness, agility, reflexes, and endurance makes him much faster than immortals, non-Original vampires, werewolves, evolved werewolves, non-Original werewolf-vampire hybrids, supernatural hunters and humans, he is slightly faster than his Original Vampire maternal half-siblings, as he once said, "I'm faster than your average vampire", even more so when he is using his lycanthrope enhancements or when he is in his werewolf form; due to his werewolf heritage. He is able to stop other supernatural species in their tracks and run miles in mere minutes. His reflexes are similarly heightened, as he once caught Connor's arm before the latter could stab him with a small stake; he later saved both himself and Connor from an explosion intentionally triggered by Connor to kill both them and Damon. Only Marcel and Lucien, as Upgraded Original vampires, have been able to surpass his speed.
* **Super Agility:** Klaus possesses much more superhuman stamina, flexibility, reflexes, agility and dexterity than any immortals, non-Original vampires, werewolves, evolved werewolves, non-Original werewolf-vampire hybrids, and humans, even slightly more than original vampires. He can move, jump very high, flip, climb and run incredibly fast without difficulty or exhaustion.
* **Super Senses:** Klaus has a more enhanced sense of hearing, sight and smell that far exceeds those of any immortals, original vampires, non-Original vampires, werewolves, evolved werewolves, non-Original werewolf-vampire hybrids and humans.
* **Super Durability:** Klaus can take far more trauma than any immortals, original vampires, non-Original vampires, werewolves, evolved werewolves, non-Original werewolf-vampire hybrids and humans, without much discomfort or injury. However, like with his maternal half-siblings, he has never been dismembered throughout the series, implying that his durability may be close to invincibility though he can still be hurt. Wood, and White Oak Ash Daggers do not weaken him, making him virtually indestructible.
* **Enhanced Healing Factor:** The injuries of Klaus heal faster than those of supernatural hunters, original vampires, non-Original vampires, werewolves, evolved werewolves, non-Original werewolf-vampire hybrids and humans. He also seems to heal much more quickly when exposed to vervain, wolfsbane, or wood. He can heal/recover/regenerate from any and all injuries in a matter of seconds. Vervain or wolfsbane laced liquid has also been shown to weaken him, though he recovers from the effects much more quickly. Human blood has also known to make the healing process faster.
* **Immortality:** Klaus is even more immortal than his maternal half-siblings. With the last White Oak Stake destroyed, no physical weapon on earth can kill Klaus. Nothing but immense magical power worth a hundred witches summoned by an exceptionally powerful witch can kill Klaus. Despite the extent of his immortality, Klaus still needs to feed otherwise he will desiccate and become immobile just like any other immortals, original vampires, non-Original vampires or non-Original hybrids. It is unknown if the bite of the Beast could kill him due to his werewolf heritage, but both Marcel and Lucien believed so.

* **Day Walking:** Due to his werewolf heritage, Klaus is immune to the lethal effects that u.v. rays and sunlight have on vampires. Allowing him to walk in daylight without the use of a day ring.
* **Emotional Control:** Due to his vampire heritage, Klaus is able to exert certain control over his own emotions, e.g. He can turn off his humanity.
* **Enhanced Emotions:** Because of his vampiric and werewolf traits, Klaus experience emotions more powerfully than humans, original vampires and non-Original vampires. Particularly emotions such as anger, rage, aggression and violence due to his werewolf heritage. Klaus is more prone to violence and rage than original vampires and non-Original vampires. However, emotions such as love, joy, and happiness are intensified for him as well, allowing him to live life more intensely. This ability allows him to feel emotions at his peak regardless of his age. Klaus has been shown experience emotions as powerfully today as he did 1,000 years ago.

* **Lycanthrope Enhancement:** Klaus is capable of using his werewolf features to further supplement his powers. Klaus can grow werewolf claws and fangs even when he is still in his human form. Klaus can display both sets of vampire and werewolf fangs. His eyes also change into those of his werewolf form, presumably granting him better eyesight. Due to his werewolf heritage, Klaus' strength and speed are heightened further during a full moon and at its peak in his werewolf form.
* **Mind Compulsion:** Klaus can compel the minds of most sentient creatures; humans, non-Original vampires and non-Original hybrids. He cannot compel supernatural hunters that are members of the Five due to them being immune to mental manipulation. Klaus cannot compel werewolves, evolved werewolves, and original vampires. His inability to compel werewolves was even confirmed by Ray Sutton.
* **Shapeshifting**/**Transformation Control:** Klaus has the ability to transform into his werewolf form at will. Elijah informs Klaus that he remained a werewolf for two days, even when the sun was up. Showing that Klaus can stay in werewolf form longer than a normal werewolf. As seen with Klaus when he bit Katherine, Klaus can transform partially, displaying his werewolf eyes and teeth.
* **Sire Bond:** Non-Original werewolf-vampire hybrids turned by Klaus had a deep sense of gratitude and commitment to him causing them to obey his every command.
* **Telepathy:** Klaus has the ability, albeit a weak variant, to enter the minds of others as long as his is stronger than them.

	+ **Illusions:** Klaus has the power to trick the minds of others into seeing/feeling things that aren't actually happening.
* **Werewolf Bite:** Due to his werewolf heritage, Klaus has venom which is fatal to non-Original vampires and Klaus himself is immune to werewolf venom. Klaus' venom seem to take effect much faster than a normal werewolf venom and a non-Original werewolf-vampire hybrid venom.
* **Werewolf Bite Cure:** Klaus' blood is the only cure for a normal werewolf or a non-Original werewolf-vampire hybrid venom, this ability seems to be unique only to Klaus and his daughter, Hope. Klaus' blood won't cure a bite from the Beast.
* **Immunity to Silver:** Due to his werewolf heritage, magic bonded to silver doesn't affect Klaus. Weapons made of silver might wound him, but the wound heals at super-normal rates than regular wounds.
* **Procreation:** Sophie explained that Klaus was only able to procreate due to being the Original hybrid — a born werewolf, turned into a vampire by magic — Nature's loophole. This has since been made impossible.

### Tribrid

Hope Mikaelson is the only known witch-werewolf-vampire tribrid known throughout the franchise, and the first hybrid of all three supernatural species, the full extent and limits of Hope's powers are currently unknown. According to Dahlia, Hope's werewolf temper and vampire blood would possibly taint her witch side. Also according to Dahlia, as a firstborn of her bloodline, Hope will inherit great, but unstable power.

* **Werewolf Gene:** Being part werewolf, Hope's body contains the werewolf gene that provides her with standard werewolf attributes provides her with enhanced senses, such as hearing, sight, and smell, as well as heightened aggression. In *The Tale of Two Wolves*, Klaus states, in response to Caroline's question, that Crescent wolves and by extension, Hope, cannot control their first transformation despite being able to control their shifts with Transformation Control as evolved werewolves. However in *This is the Part Where You Run*, Hope accounts to Landon that her ability to control her transformation stems from her tribrid status, as like with other werewolf-vampire hybrids. Currently, whether it's the former or latter which grants her transformation control, or additional abilities, remains unknown.

* **Vampire Gene:** Being part vampire, Hope's body produces vampire blood which is constantly running through her system, tainted with dark magic.
	+ **Enhanced Healing Factor:** Hope can heal from injuries with a speed comparable to normal vampires. Her blood also retains the vampiric ability to heal others as Hope was able to heal her mother while in the womb.
	+ **Siring:** Hope's blood has the ability to turn werewolves into hybrids as long as they first drink her blood during the transition.

* **Werewolf Bite Cure:** Hope's blood is the only cure for a normal werewolf or a non-Original werewolf-vampire hybrid venom; this ability was inherited from her father, the Original hybrid, Niklaus. Like Klaus' blood, Hope's blood cannot cure a bite from the Beast.
* **Malivore Mud Bullets Cure:** Unique to Hope, as her status of being one of Nature's loopholes, her blood is also a curative to Malivore mud bullets, weaponized by Triad scientists; this was proven when her blood healed Josie's wound.

* **Desiccation:** Being completely drained of blood or the heart stopping will cause an original werewolf-vampire hybrid to desiccate due to their vampire side, losing most of it's strength and any ability to move. This process can be replicated artificially by magic.
* **Invitation:** Due to their vampire heritage, original werewolf-vampire hybrids are unable to enter a home without an invitation.
* **Magic:** Original werewolf-vampire hybrids are susceptible to the powers of witchcraft. This is inclusive of mystical objects such as the Starling Necklace, Gilbert Device, Papa Tunde's Blade, Cursed Stake and Dark Objects. It is possible, but equally as unlikely that a Siphoner can also siphon the magic from an original hybrid.
* **Physical Trauma:** Minor physical injuries such as gunshots, stab wounds and broken bones will cause an original werewolf-vampire hybrid pain and also slow them down. However, this is momentary as they will heal completely within seconds. It seems physical trauma can hurt them anywhere on the body (ex-eye gauging, drowning).
* **Poison:** There have recently been various poisons shown invented by people such as Dr. Wes Maxfield and Aya that are capable of incapacitate or desiccate a vampire when administered. Klaus also used a poison to kill Tim that not even vampire blood could cure. Davina used a spell that made her blood toxic to Klaus, paralyzing and rendering him unconscious. It is unknown what effect any of these poisons would do if ingested by an original werewolf-vampire hybrid.
* **Vervain:** Vervain prevents an original werewolf-vampire hybrid from compelling anyone who takes it and burns them on touch. Original werewolf-vampire hybrid will heal very quickly from vervain wounds however.
* **Wolfsbane:** When ingested, wolfsbane causes an original werewolf-vampire hybrid to become severely weak and feverish. Also, If an original werewolf-vampire hybrid's skin is exposed to wolfsbane, it will burn them. Original werewolf-vampire hybrid will heal very quickly from wolfsbane wounds however.

* **Disbelief:** The act of denying or disbelieving in one's potential could cause Hope to inadvertently suppress their magical power.
* **Distraction:** Denying Hope from concentrating or giving full attention to her spells, may render them ineffective.
* **Emotions:** Hope's magic is subject to the influence of her emotional state and may fluctuate according to them when untrained. According to Sheila Bennett, strong emotions such as worry and anger can fuel a witch's power while emotions such as fear may prevent a witch from properly accessing their powers.
* **Herbs:** Ingestion of certain herbs can cause a witch to lose consciousness and prevent them from using magic for a undetermined amount of time. The Lobelia flower prevents concentration and the practice of magic and can be used to weaken a witch as one would weaken a vampire with vervain. Being part werewolf and vampire, she may also acquire the adverse effects of wolfsbane and vervain as well.
* **Huntress' Blood:** Consumption of a supernatural huntress' blood will cause a witch to lose their ability to use magic. Prolong exposure poisons them, leading them to get sick and some brands will appear in their body and may eventually lead to death. According to Alex and Rayna Cruz, Rayna's blood can't be reversed for anything and all the attempts to make a cure were unsuccessful. It is unknown what effect Rayna's blood has on Hope.
* **Magic:** Hope is still susceptible to the powers of witchcraft. This is inclusive of mystical objects such as Papa Tunde's Blade, her bracelet and Dark Objects. A siphoner can siphon the magic from a witch where prolong exposure may lead to death.
* **Mortality:** Despite her mystical attributes, Hope is still human and share many of the same weaknesses as non-supernatural beings (e.g. age, decapitation, disease, heart-failure, suffocation, snapped neck, etc.)
* **Overexertion:** The excessive use of magic could lead to disorientation, nose bleeds, unconsciousness, and if taken to the extreme, death.
* **Unique Physiology:** Being born with aspects of all three species, Hope's nature are somewhat at odds with each other. Dahlia deduces that without proper guidance, Hope's potential as a firstborn of her family's bloodline will prove destructive and unstable when mingled with vampire blood and werewolf aggression.
	+ **Death:** Having been born with vampire blood constantly produced in her system, Hope has the potential for vampirism upon death.
	+ **Murder:** Having been born with the werewolf gene, Hope has the potential for lycanthropy when she kills someone.
