Hybrid

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 hybrids, 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 siphoners; this is a skill that makes them powerful.
==Creation==
===The Original Hybrid===
Niklaus Mikaelson was conceived when his mother Esther had an affair with Ansel, the Alpha of the North East Atlantic werewolf pack. Her affair, as well as Klaus' werewolf heritage, was kept a secret from everyone. However, when Klaus made his first human kill after being turned into an Original vampire, he triggered his werewolf gene, which turned him into the world's first hybrid. However, his werewolf nature was bound by Esther with the the Hybrid Curse, causing it to become dormant.
===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 their transition by drinking the blood of a human Petrova doppelgänger. After Elena transitioned into a vampire, her blood became useless to Klaus and he could no longer create more hybrids. If a werewolf is turned with Hope's blood, her blood must be used to complete their transition. Since Hope's transition into a tribrid, her blood has never been used to create any new hybrids or vampires. 
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. Klaus learned of these results when he first attempt to turn werewolves into hybrids in The Hybrid after he sired Paige's Pack. However, it is unclear why this happens. After being sired, they all began to experience unbearable pain and profuse bleeding from their facial orifices until they killed each other, mercy-killed by Klaus, or died of failed transitions combined with exsanguination.
===Siphoner-Vampire Hybrids===
 & Heretics
The hybridization of witches and vampires is impossible. Witches are servants of Nature while vampires are aberrations of Nature. When a witch transitions into a vampire, they lose their connection to Nature and are unable to practice magic. However, a subsection of aberrant witches, known as siphoners, are unique to this. Siphoners have no magic of their own, yet possess the ability to siphon magic from others. When they are turned into a vampire, the siphoner witch retains their ability to siphon magic and, as a vampire, access to siphon from themselves to cast spells. Lillian Salvatore found and befriended a group of siphoners that were cast out from the Gemini Coven. Eventually, she turned them into siphoner witch-vampire hybrids—her "family", the Heretics.
===The Tribrid===
The birth of Hope Mikaelson was one of Nature's loopholes. Sophie Deveraux explained that Klaus was only able to procreate due to being the Original hybrid; he was a born werewolf, turned into a vampire by magic, as opposed to transitioning by vampire blood. Tyler also explained that when he broke the curse that kept his werewolf side dormant, certain parts were now able to trump his vampire side—like the ability to pass on the werewolf gene. At the time of Hope's conception, Hayley Marshall was a triggered werewolf while Klaus was the Original hybrid. Hope Mikaelson was born as a living 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 blood from her father. Though a tribrid, she was still required to activate her werewolf curse by killing another human as well as dying and transitioning into a fully activated tribrid.
Immediately after Hope's birth, Hayley was killed, but because Hope's blood was still in her system, she reawakened in transition. To complete her transition as a werewolf-vampire hybrid, she had to drink another "drop" of Hope's blood. Since becoming a fully activated tribrid, it is unclear if her blood can still create hybrids, similar to how Elena's undead blood become useless for Klaus.
===Vampire-Dragon Hybrid===
Though an unconventional and unique "hybrid," Kaleb Hawkins was transformed by the golem Malivore by transferring a dragon into him while as a non-Original vampire. Malivore used him as a thrall to which he could directly control to do his bidding. When Hope stabbed Kaleb in the dragon's soft spot, Kaleb temporarily died and later revived. Though the effects of Malivore's control and the possessing dragon were gone, he retained some of his dragon abilities, describing himself as only "part" dragon. For a lack of a better description, he is classified as a vampire-dragon hybrid, though the term "hybrid" was never used. Furthermore, Kaleb doesn't fully understand his new dragon-nature. He also refers to the duality of abilities as his "monster" side, which in some situations seems to be able to take over to the extent to where he can't control himself.

==Powers and Abilities==
<tabber>
|-|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. These 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, fighting a non-Original vampire closer to their age range, the hybrid will win. Ray Sutton, a dying, unsuccessful hybrid, was very strong and nearly killed Damon, a non-Original vampire more than 170 years old until Stefan saved him. Such hybrids are even capable of putting up a fight against non-Original vampires well above their age range such as when Tyler gained the upper hand and bit Nadia, a 500-year-old non-Original vampire. Nadia did, however, 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.
*Super Speed: A non-Original werewolf-vampire hybrid's intensified quickness, agility, reflexes, and endurance makes them faster than many other human and supernatural beings. They can use this ability in either human or werewolf form. As with strength, hybrids get faster with time, while the full moon or being in wolf form will make them even faster. Tyler was particularly fast, fast enough to surprise Klaus and stake him.
*Super Agility: Non-Original werewolf-vampire hybrids possess much more superhuman stamina, flexibility, reflexes, agility, and dexterity than many humans and supernatural beings. 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 other supernatural beings and humans. As hybrids, their senses are superior to the individual species, making their ability extremely effective. Tyler has used 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. A prime example of this ability is in "Home"; after Tyler is resurrected, he tells Caroline that it felt different, because he was no longer a hybrid.
*Super Durability: Non-Original werewolf-vampire hybrids can bear a lot of trauma. They also hardly ever get tired or fatigued and can take far more trauma than other supernatural beings and humans, without much discomfort or injury. Stakes and arrows cannot kill them 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; Tyler even states to Stefan that he would be dead if he was a normal vampire
*Enhanced Healing Factor: Non-Original werewolf-vampire hybrids have superior healing capabilities and can recover from most injuries much quicker and more effectively than their individual species. This renders them practically invincible to anything but fatal wounds that can seriously impair their healing capabilities, such as decapitation or heart extraction.. They also seem to heal much more quickly when exposed to vervain, wolfsbane, or wood. Human blood has also been known to make the healing process faster.
*Immortality: Non-Original werewolf-vampire hybrids stop 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 UV rays and sunlight have on non-Original vampires and Original vampires. This allows them to walk in daylight without the use of a daylight ring.
*Emotional Control: Due to their vampire heritage, non-Original werewolf-vampire hybrids are able to exert certain control over their own emotions, such that they can turn off their humanity.
*Enhanced Emotions: Non-Original werewolf-vampire hybrids experience emotions more powerfully than humans and non-Original vampires. Particularly due to their werewolf heritage, they are more prone to emotions of anger, rage, aggression, and violence. However, emotions such as love, joy, and happiness are also 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. They can grow claws from their nails and werewolf fangs from their teeth even when they are still in their human forms. When Klaus possessed Tyler's body, he demonstrated that their claws are sharp enough to penetrate their own very durable skin. They can also 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, their 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 other supernatural beings.
*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, such as displaying their werewolf eyes, teeth or claws. Elijah informs Klaus that he remained a werewolf for two full days, much longer than a normal werewolf.
*Sire Bond: Non-Original werewolf-vampire hybrids become sired to the source of their creation. Those turned by Klaus had a deep sense of gratitude and commitment to him, causing them to obey his every command. They are, however, capable of breaking a sire bond if they transform into their werewolf forms an excess, repeatedly, i.e. 100 times in a row. Transforming as such 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 thereby breaking the sire bond.
*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 requires physical contact in order for it to work successfully. Hayley has shared 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. They can produce and modify dreams, bestow nightmares, or lucid dreaming. Other effects of this ability are the distortion of reality and trapped in dreams.
**Illusions: Non-Original werewolf-vampire hybrids have the power to trick the minds of others into seeing and feeling things that aren't actually happening.
*Werewolf Bite: Due to their werewolf heritage, non-Original werewolf-vampire hybrids have venom which is fatal to non-Original vampires. It is assumed they are immune to werewolf venom. Their venom also seems to take effect much faster than a normal werewolf's venom.
*Immunity to Silver: Due to their werewolf heritage, magic bound 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=
The hybridization of a witch and a vampire has long been impossible. However, a subsection of aberrant witches with no power of their own, yet the ability to siphon magic from others, known as siphoners, are unique to this rule. When turned into a vampire, the siphoner witch retains their ability to siphon magic and, as a vampire, access to siphon from themselves to cast spells. A group known as the Heretics consisted of these hybrids.
*Siphoning: Non-Original witch-vampire hybrids possess the rare ability to absorb magic, in many forms, from another source.
*Spell Casting: Non-Original witch-vampire hybrids, after having absorbed magic, possess the ability to cast spells like any witch.
*Telekinesis: Non-Original witch-vampire hybrids, after having absorbed magic, possess the ability to move objects and people with the mind like any witch.
*Pain Infliction: Non-Original witch-vampire hybrids, after having absorbed magic, possess the ability to inflict excruciating migraines like any witch.
*Pyrokinesis: Non-Original witch-vampire hybrids, after having absorbed magic, possess the ability to create and control fire like any witch.
*Divination: Non-Original witch-vampire hybrids, after having absorbed magic, possess the ability to divine future, past, and present events based on extrasensory perception like any witch.
*Super Strength: Non-Original witch-vampire hybrids have the same strength as that of non-Original vampires and are noticeably much stronger than Supernatural Hunters, immortals and humans and slowly grow stronger with time. 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 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. Even vampires who have been shot with wooden bullets have been seen to continue fighting, as long as they were not shot in the heart, or the head. As they get older they become more powerful.
*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 immune to the lethal effects that UV 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" 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. Like their physical attributes, their mental strength increases with age.
**Dream Manipulation: Non-Original witch-vampire hybrids can control dreams and subconscious. They can produce and modify dreams, bestow nightmares or lucid dreaming. Other effects of this ability is the distortion of reality and trapping people in their dreams.
**Illusions: Non-Original witch-vampire hybrids have the power to trick the minds of others into seeing/feeling things that aren't actually happening.
*True Face: A non-Original witch-vampire hybrid's true face is the appearance they are hiding under their normal human face. 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 Vivianne Lescheres are the only two known witch-werewolf hybrids, though Klaus was untapped prior to becoming an Original vampire, and 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 on extrasensory perception.
*Super Strength: Witch-werewolf hybrids have the same strength as werewolves and are noticeably much stronger than Supernatural Hunters, immortals and humans, though to a lesser degree than vampires. When they are in their wolf forms, their powers amplify to a degree that exceeds that of the non-Original vampires and can overpower and kill them with ease.
*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.
*Super Durability: Witch-werewolf hybrids can take 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. They can heal from many non-fatal injuries, even in human form, albeit more slowly in comparison to vampires.
*Super Senses: Witch-werewolf hybrids have the extremely keen and supernatural heightened senses of smell, sight, taste, hearing and touch inherent in all 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 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 a 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, then finally death.
*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, though non-fatal wounds will still heal at supernatural rates.
|-|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 many other supernatural beings 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. Both 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 other supernatural beings.
*Super Durability: Klaus can take far more trauma than other supernatural beings without much discomfort or injury. However, like with his maternal half-siblings, he has never been dismembered, 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: Klaus heals and recovers faster from any and all injuries than those of other supernatural beings. He also seems to heal much more quickly when exposed to vervain, wolfsbane, or wood than the individual species. 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 been known to make the healing process faster.
*Immortality: 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, or the bite of an Upgraded Original vampire, 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 immortal or vampire-based species.
*Day Walking: Due to his werewolf heritage, Klaus is immune to the lethal effects that UV rays and sunlight have on vampires thus allowing him to walk in daylight without the use of a daylight ring.
*Emotional Control: Due to his vampire heritage, Klaus is able to exert certain control over his own emotions and can turn off his humanity.
*Enhanced Emotions: Because of his vampiric and werewolf traits, Klaus experiences emotions more powerfully than humans and other supernatural beings. Particularly due to his werewolf heritage, he experiences emotions such as anger, rage, aggression, and violence more deeply and more prone to violence and rage than the other 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.
*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, or any of the other 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 informed Klaus that he remained a wolf for two days, even when the sun was up. He can transform some features 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 he is stronger than them. Normally, this ability works in a tactile fashion and requires physical contact to work successfully. Klaus has also been able to share his memories with others.
**Dream Manipulation: Klaus can control dreams and subconsciousness. He can produce and modify dreams, bestow nightmares, or lucid dreaming. Other effects of this ability are the distortion of reality and trapped in the dreams.
**Illusions: Klaus has the power to trick the minds of others into seeing or 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 seems 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. However, Klaus' blood won't cure a bite from the Upgraded Original vampire.
*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 and 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. Furthermore, as a firstborn of her bloodline, Hope will inherit great, but unstable power. As of See You On The Other Side, Hope completed her transition into a fully activated tribrid, giving her access to all of her abilities.
*Werewolf Nature: Being part werewolf, Hope's body contains the werewolf gene that provides her with standard werewolf attributes and provides her with enhanced senses, such as hearing, sight, and smell, as well as heightened aggression. Hope even demonstrated that she can tell when someone is lying to them by listening to their heartbeat. 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 explains to Landon that her ability to control her transformation stems from her tribrid status, as with other werewolf-vampire hybrids. Currently, whether it's the former or latter which grants her transformation control or additional abilities, remains unknown.
*Vampire Nature: Being part vampire and prior to transitioning, Hope's body naturally produced vampire blood, constantly running through her system, tainted with dark magic. As a fully transitioned tribrid, she seemingly possesses all the abilities of at least a non-Original vampire, such as compulsion. In I Thought You'd Be Happier To See Me, Hope compelled a vampire bartender who was sent by Triad Industries to spy on her, and later, compelled a much older vampire in Follow the Sound of My Voice.
**Enhanced Healing Factor: Hope can heal from injuries with a speed comparable to non-Original 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 werewolf-vampire hybrids as long as they drink her blood before dying and after, completing the transition, such as with Henry Benoit. She can also sire vampire-witch hybrids without the need for them to drink her blood after such as with Lizzie Saltzman, having completed her transition by feeding on Rupert Vardemus.
*Witch Nature: Being part witch, Hope can channel vast amounts of mystical energy. According to Dahlia, as a firstborn of her bloodline, Hope has the potential for great, but destructive magic. As a fully activated tribrid, she can still practice magic and cast spells.
**Channeling: Hope has the power to invoke extra forms of energy by focusing on external forces.
**Potion Brewing: Hope has the power to brew and concoct potions, remedies and elixirs that have supernatural properties.
**Spell Casting: Hope has the power to change and control events through the use of incantations and more.
**Divination: Hope has the power to divine future, past, and present events based on extrasensory perception.
*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 Upgraded Original vampire.
*Malivore Mud Bullets Cure: Unique to Hope, as her status of being one of Nature's loopholes and a tribrid, her blood is also a curative to Malivore mud bullets, weaponized by Triad scientists. Though Lizzie could not siphon Josie's wound, Hope's blood was a curative. Her blood is also lethal to Malivore himself and what caused his ultimate destruction while possessing Landon.
|-|Vampire-Dragon=
Kaleb is, for a lack of a better description, a vampire-dragon hybrid, though the term "hybrid" was never used. Kaleb describes himself as only "part" dragon. Under the thrall of Malivore, he transferred a dragon into Kaleb's body and used him to do his bidding. When Hope stabbed Kaleb in the dragon's soft spot, Kaleb died, though when he revived, he retained some of his dragon abilities. Understandably, an unusual conception to create a hybrid.
*Vampire Nature: As a vampire, Kaleb possesses all the abilities of a non-Original vampire.
*Dragon Nature: When possessed by a dragon, transferred into him by Malivore, Kaleb, rather the possessing dragon, possessed all the abilities of a dragon, such as fire-breathing and, at least, partial transformation. The dragon only demonstrated the ability to produce wings from Kaleb's back. After Kaleb revived, and Malivore was defeated, he still felt like himself, but could breath smoke from his nostril and he believed he was still part dragon. The full extent of this is unknown.

==Weaknesses==
<tabber>
|-|Werewolf-Vampire=
*Broken Neck: Breaking a non-Original werewolf-vampire hybrid's neck will result in their temporary death, though they will revive a short time later.
*The Cure: If a non-Original werewolf-vampire hybrid takes the cure, they will revert back to being a werewolf again. Once taken, the cure prevents them from being immortal again, causing the body to reject vampire blood.
*Decapitation: Dismembering or removing the head of a non-Original werewolf-vampire hybrid will result in instant death.
*Desiccation: Being completely drained of blood or the heart-stopping will cause a non-Original werewolf-vampire hybrid to desiccate due to their vampire side, losing most of its strength and any ability to move. This process can be replicated artificially by magic.
*Heart Extraction: Removing a non-Original werewolf-vampire hybrid's heart will result in instant death.
*Hybrid Bloodline: If Klaus dies, then all the non-Original werewolf-vampire hybrids he created will die along with them. This, however, has been broken due to the sireline unlinking spell cast upon him.
*Invitation: Due to their vampire heritage, non-Original werewolf-vampire hybrids are unable to enter a home without an invitation.
*Magic: Non-Original werewolf-vampire hybrids are susceptible to the powers of witchcraft. This is inclusive of mystical and dark objects.
*Physical Trauma: Minor physical injuries such as gunshots, stab wounds, and broken bones will cause a non-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 give them pain and weaken them anywhere on the body (i.e. eye gouging, drowning, etc.).
*Poison: There are various poisons invented by Dr. Wes Maxfield and Aya, to name a few, that are capable of incapacitating or desiccating a vampire when administered. Klaus also used a poison to kill Tim that not even vampire blood could cure. It is unknown what effect, if any, any of these poisons would have if ingested by a non-Original werewolf-vampire hybrid.
*Vervain: Non-Original werewolf-vampire hybrids are affected by vervain and they can't compel anyone on vervain.
*Wolfsbane: Non-Original werewolf-vampire hybrids are affected by wolfsbane like their werewolf counterparts.
*Wood: Wounding non-Original werewolf-vampire hybrids with a wooden weapon such as wooden bullets will incapacitate for a shorter time than a non-Original vampire.
|-|Witch-Vampire=
*Broken Neck: Breaking a non-Original witch-vampire hybrid's neck will result in temporary death, though they will revive a short time later.
*The Cure: If a non-Original witch-vampire hybrid takes the cure, they will revert back to being a witch again. Once taken, the cure prevents them from being immortal again, causing the body to reject vampire blood.
*Decapitation: Dismembering or removing the head of a non-Original witch-vampire hybrid will result in instant death.
*Desiccation: Being completely drained of blood or the heart-stopping will cause a non-Original witch-vampire hybrid to desiccate due to their vampire side, losing most of their strength and any ability to move. This process can be replicated artificially by magic.
*Distraction: Denying a non-Original witch-vampire hybrid from concentrating or giving full attention to their spells, may render them ineffective.
*Emotions: A non-Original witch-vampire hybrid's magic is subject to the influence of their 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. This may be made more intense due to a vampire's heightened emotions.
*Heart Extraction: Removing a non-Original witch-vampire hybrid's heart will result in instant death.
*Herbs: Ingestion of certain herbs can cause loss of consciousness and prevent them from using magic for an undetermined amount of time. The Lobelia flower prevents concentration and the practice of magic and by witches can be used to weaken a non-Original witch-vampire hybrid as one would weaken a vampire with vervain.
**Vervain: Due to their vampire aspect, vervain causes a non-Original witch-vampire hybrid to become severely weak and feverish with exposure to or ingestion. Also, If a non-Original witch-vampire hybrid's skin is exposed to vervain, it will burn them. Furthermore, they can't compel anyone on vervain.
*Huntress' Blood: Consumption of a supernatural huntress' blood will cause a non-Original witch-vampire hybrid to lose their ability to use magic. Prolong exposure poisons them, leading them to get sick. When scabs begin to appear on their body, it eventually leads 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.
*Hybrid Bloodline: If an Original vampire dies, then all the non-Original witch-vampire hybrids they created will die along with them.
*Invitation: Due to their vampire heritage, non-Original witch-vampire hybrids are unable to enter a home without an invitation.
*Magic: Non-Original witch-vampire hybrids are susceptible to the powers of witchcraft. This is inclusive of mystical and dark objects.
*Overexertion: If too much power is siphoned from a non-Original witch-vampire hybrid's blood at a time, they may begin to desiccate and ultimately die. Overtaxing themselves can also lead them to experience physical symptoms, such as nosebleeds.
*Physical Contact: Non-Original witch-vampire hybrids need physical contact with their source in order to siphon from them.
*Physical Trauma: Minor physical injuries such as gunshots, stab wounds, and broken bones will cause a non-Original witch-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 (i.e. eye gouging, drowning, etc.).
*Poison: There are various poisons invented by Dr. Wes Maxfield and Aya, to name a few, that are capable of incapacitating or desiccating a vampire when administered. Klaus also used a poison to kill Tim that not even vampire blood could cure. It is unknown what effect, if any, any of these poisons would have if ingested by a non-Original witch-vampire hybrid.
*Werewolf Bite: Non-Original witch-vampire hybrids are still susceptible to the bite of a werewolf. However, they are able to siphon the magic from the venom, disabling its effects.
*Wood: Stakes can harm and kill a non-Original witch-vampire hybrid.
*Cancer: Although vampires cannot catch diseases and illnesses such as cancer, if a human has active cancer and is turned into a vampire, the effects of cancer will increase. The regenerative properties of vampire blood will speed up the replication of cancer cells and exceed normal stages of the condition. The effects on non-Original witch-vampire hybrids would most likely be affected the same way as non-Original vampires.
|-|Witch-Werewolf=
*Blood Loss: If a witch-werewolf hybrid is severely wounded and bleeds out before they can heal, they can die.
*Broken Neck: Breaking a witch-werewolf hybrid's neck will result in instant death.
*Decapitation: Decapitation will result in instant death for a witch-werewolf hybrid.
*Disbelief: The act of denying or disbelieving in one's potential could cause a witch-werewolf hybrid to inadvertently suppress their magical power.
*Distraction: Denying a witch-werewolf from concentrating or giving full attention to their spells, may render them ineffective.
*Emotions: A witch-werewolf hybrid's magic is subject to the influence of their 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.
*Fire: Fire can presumably kill a witch-werewolf hybrid. It can also hurt them.
*Heart Extraction: Ripping a witch-werewolf hybrid's heart out will result in instant death.
*Herbs: Ingestion of certain herbs can cause a witch-werewolf hybrid to lose consciousness and prevent them from using magic for an undetermined amount of time. The Lobelia flower prevents concentration and the practice of magic and can be used to weaken a witch-werewolf hybrid as one would weaken a vampire with vervain.
**Wolfsbane: Due to their werewolf aspect wolfsbane causes a witch-werewolf hybrid to become severely weak and feverish when ingested. Also, If a Witch-werewolf hybrid's skin is exposed to wolfsbane, it will burn them.
*Huntress' Blood: Consumption of a supernatural huntress' blood will cause a witch to lose their ability to use magic. Prolonged exposure poisons them, leading them to get sick. When scabs begin to appear on their body, it eventually leads 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 witch-werewolf hybrids.
*Magic: Witch-werewolf hybrids are susceptible to the powers of witchcraft. This is inclusive of mystical and dark objects. A siphoner can siphon the magic from a witch-werewolf.
*Mortality: Witch-werewolf hybrids can die of old age and share many of the same weaknesses as non-supernatural beings (e.g. suffocation).
*Overexertion: The excessive use of magic could lead to disorientation, nose bleeds, unconsciousness, and if taken to the extreme, death.
*Physical Trauma: Minor physical injuries such as gunshots, stab wounds, and broken bones will cause a witch-werewolf hybrid pain and will also slow them down. However, this is only temporary, as they will be able to heal from most minor physical injuries.
|-|Original Hybrid=
*Broken Neck: Breaking an original werewolf-vampire hybrid's neck will result in temporary death, though they will revive a short time later.
*The Cure: If an Original werewolf-vampire hybrid takes the cure, they will revert back to being a werewolf again. Once taken, the cure prevents them from being immortal again, causing the body to reject vampire blood.
*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 their 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 and dark objects such as the Starling Necklace, Gilbert Device, Papa Tunde's Blade, Cursed Stake.
*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 (i.e. eye gouging, drowning, etc).
*Poison: There are various poisons invented by Dr. Wes Maxfield and Aya, to name a few, that are capable of incapacitating or desiccating a vampire when administered. Klaus also used a poison to kill Tim that not even vampire blood could cure. It is unknown what effect, if any, any of these poisons would have if ingested by a non-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 hybrids 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.
|-|Tribrid=
*Disbelief: The act of denying or disbelieving in one's potential could cause Hope to inadvertently suppress her 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 it 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 an 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. When scabs appear on their body, it eventually leads 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 would have on Hope.
* Magic: Hope is still susceptible to the powers of witchcraft. This is inclusive of mystical and dark objects. A siphoner can siphon the magic from a witch where prolonged exposure may lead to death, albeit perhaps prior to transitioning into a fully activated tribrid.
*Overexertion: The excessive use of magic could lead to disorientation, nose bleeds, unconsciousness, and if taken to the extreme, death. As a fully activated tribrid, death seems temporary.
*Broken Neck: Breaking Hope's neck will result in her temporary death, though she will revive a short time later.
*Invitation: Due to her vampire heritage, Hope, as a fully activated tribrid, is unable to enter a home without an invitation.
*Desiccation: Being completely drained of blood or the heart-stopping will cause a Tribrid to desiccate due to their vampire side, losing most of their strength and any ability to move. This process can be replicated artificially by magic.
*Unique Physiology: Being born with aspects of all three species, Hope's nature is 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.
*Wood: A wooden stake through the heart will desiccate Hope and temporarily "kill" her. However, wood from a Red Oak tree can permanently destroy Hope as Nature created a balance near the site of the tribrid's birth through the sapling that she, Lizzie and Josie created. In the Therapy Box simulation, Cleo tested her theory and Hope was stabbed and immediately turned to ash. The validity of this, however, has not been tested outside of the simulation. The tree, however, was chopped down and rendered to ash.
*White Oak Ash Daggers: A collection of enchanted silver daggers dipped in the ash of the white oak tree will neutralize Hope when stabbed through the heart, causing her to desiccate. However, the effects are only temporary and they will wear off in a short amount of time. It's unknown if Hope directly overcame the desiccation, and pulled the dagger out, or if the desiccation slowly receded, revived and then removed the dagger. Due to her werewolf-nature, magic bonded to silver likely doesn't affect her or, in this case, only temporarily weakens her.
*God Spear: Smithed by Jen, it is a divine weapon forged with god magic and Red Oak ash. It is a lethal combo for Hope, provided it's stabbed into her heart. Since it's forged with god magic, it also renders her witchcraft useless. Injuries from this weapon causes the poisonousness effects of the Red oak to make its way through her bloodstream, though given Jen's claim, it is unlikely to kill her outright. This poisonousness effect can be reversed by siphoning.
|-|Vampire-Dragon=
*Vampire Nature: As a vampire, Kaleb possesses all the standard weaknesses of a non-Original vampire.
*Dragon Nature: When possessed by a dragon, transferred into him by Malivore, Kaleb, rather the possessing dragon, possessed all the standard weaknesses of a dragon such as soft spot vulnerability. However, since Kaleb the host of the dragon was a vampire, this seemingly only killed the possessing dragon and Kaleb revived, albeit still part dragon.
</tabber>
==Former Weaknesses==
*Doppelgänger Blood Magic: If blood from the last pair of doppelgängers is used in the Magic Purification Spell, all hybrids created with non-Traditional magic will have their powers stripped from them little by little. If the hybrid is vampire based, they will be brought back to the last stage of their werewolf or siphon witch life which is death. They will then relive the way they died when they went into transition to the point where they die again. It is assumed that a witch-werewolf hybrid will revert to their state prior to triggering their curse. Since Kai absorbed the magic of the magic purification spell that once surrounded Mystic Falls, this is no longer a concern for a weakness.
===Original Hybrid===
*Golden White Oak Ash Dagger: A weapon originally forged by witches and transmuted by Kol and Davina using Kemiya as a way to subdue Niklaus since he is unaffected by White Oak Ash Daggers. If dipped into the White Oak ashes and then stabbed into Klaus' heart, he will be neutralized and desiccate and will remain that way for as long as the dagger stays in place. As of Ashes to Ashes, the dagger was melted and destroyed by Dahlia.
*White Oak Stake: The White Oak Stake was the only weapon on Earth that could permanently kill Klaus. As of When The Saints Go Marching In, Klaus and Elijah used the last remaining stake to stake each other.
*Enchanted Thorns: Magically infused thorns created by the Hollow, that were grown in the ground laced with Marcel's blood, an Upgraded Original Vampire. A single scratch from these thorns will kill an Original; as of Phantomesque, the rosebush and thorns have all been destroyed.
