==Voice Cast and Characters==
==Characters==
===Protagonists===
* (voiced by Scott Wolf) - The half-Japanese main protagonist of the series who is the son of Ken Okamoto and Janet Pierce-Okamoto. He lives on the central California coast in the city of San Campion with his mom and paternal grandfather. His creature partner is Tatsurion the Unchained. Raiden's natural ability to befriend the creatures comes from his father Ken Okamoto (who The Choten converted into Saguru) and his birth in the Creature Realms when Ken and Janet were hiding in the Nature Civilization from The Choten.
* (voiced by Kari Wahlgren) - A girl who has been friends with Ray since their childhood, she has a wealthy father but does not act like a stereotypical rich girl. She is fiercely independent and extremely adventurous. Her creature partner is Scaradorable of Gloom Hollow. Her mother Piper ran away before her tenth birthday, although the reason has not yet been explained.
* (voiced by Phil LaMarr) - A friend of Ray, he is more direct than most people, but is honest and true. His creature partner is Reef Prince Glu-urrgle. He later meets Sasha, Channeler of Light who becomes his second partner. Following the fight at The Choten's base and the treachery of Master Nigel, Gabe is later chosen as the temporary Duel Master of the Light Civilization (due to his connection with Sasha) until the Duel Masters can find a suitable replacement for Nigel.
===Duel Masters===
* Master Hector Chavez (voiced by Freddy Rodriguez) - A Duel Master and expert on the Fire Civilization, Master Hector Chavez is always on the front lines of Earth, where he fights any creatures that come through the tears in the Veil. His creature partner is Gilaflame the Assaulter. During both "Heart Of Darkness" episodes, he has given hints that he has a crush on Master Nadia. By the episode "The Rising" Pt. 2, Master Jaha tells Master Chavez and Master Nadia to admit their feelings towards each other as they both kiss.
* Master Jaha (voiced by Dee Bradley Baker) - An elderly dwarfish female Duel Master, she is the most resourceful of the group and an expert on the Darkness Civilization. Her creature partner is Black Feather of Shadow Abyss. Master Jaha collects secrets kept hidden on both sides of the Veil. She was the Darkness Duel Master when The Choten was still in the order. In the episode "Heart of Darkness" Part 2, Megaria the Collector and Master Jaha reveal that they have known each other for a long time. Master Jaha may once have been Megaria's protege. Master Jaha says that her walking cane was a part of Megaria's brother. In the episode "The Rising" Pt. 1 during the fight at The Choten's base, Master Jaha sides with The Choten. When Master Chavez asks Master Jaha why she sided with Choten, Master Jaha says, "I'm sorry, Chavez. This is the way of darkness." She orders the freed Black Feather of Shadow Abyss to attack Master Chavez. In "The Rising" Pt. 2, it turns out that this is a ruse to knock out Master Nigel as she quotes to Master Chavez "those who work with darkness works in mysterious ways." In "Siege," Master Jaha was aged by Megaria during the Choten's siege of the Duel Master's temple. In "The Evolution Will Not Be Televised," Master Isao Okamoto uses his mana to keep Master Jaha alive. When the Spell of Radiant Purification is cast by Raiden, the curse on Master Jaha is undone as she finds herself younger, (and taller), than she was before.
* Master Benjirou Kimora (voiced by Andrew Kishino) - A sumo-like Duel Master and expert on the Nature Civilization, Master Benjirou Kimora serves as the front man for the martial arts dojo that hides the Duel Masters Temple. His creature partner is Mighty Shouter. He succeeds the previous Nature Duel Master Ken Takahashi Okamoto (Ray's father).
* Master Nadia Lobachevsky (voiced by Grey DeLisle in a Russian accent) - A female Duel Master and expert on the Water Civilization, she has spent years studying the Creature Realms and the Veil that protects the Creature Realms and Earth from each other. In the past, when The Choten was a Duel Master at the Kaijudo Temple, Nadia was an acolyte. Her creature partner is Aqua Chaser, Rusalka. During both "Heart Of Darkness" episodes, Master Chavez has shown signs of having a crush on Master Nadia. By the episode "The Rising" Part 2, Master Jaha tells Master Chavez and Master Nadia to admit their feelings towards each other as they both kiss.
===Evil Forces===
* The Choten (voiced by Oded Fehr) - The primary antagonist of the series. His real name is August. The Choten is an evil genius and a former Duel Master that went rogue to pursue his own goals. He may have been the former Water Civilization Duel Master, preceding Master Nadia. His main creature partner is Aqua Seneschal, and he has a secondary creature partner named Trox, General of Destruction. Both creatures help the Choten with his plots. From his hideout in the Skidbladner ship, the Choten has many allies to help him in his goals to enslave the creatures and take over Earth once the Veil that separates both worlds is brought down. The Choten seeks the artifacts of the Five Civilizations in order to control the creatures and take over Earth. When the Choten finally collects all five relics of the Five Civilizations, he announces that it is time for the Creature Kings to rise. In the episode "The Rising" Part 1, the Choten goes to great lengths to capture the Duel Masters' creatures in order to prevent them from interfering with his plan of summoning the Creature Civilization Monarchs. He succeeds in awakening them and summons King Tritonus to him. In "The Rising" Part 2, the Choten summons Infernus the Immolator, Almighty Colossus, Queen Kalima, and Eternal Haven to him in order to take down the Veil. When the Veil is restored, The Choten and his base end up in the Creature World alongside Master Nigel, Fingers, and Heller. The Choten plans to make his army within the Creature World. He starts by using the Helm of Ultimate Technology to control King Tritonus in order to use Water Civilization technology to repair and upgrade the Skidbladner. Upon obtaining the horns from some of the Rumbling Terrasaurs, the Choten forms an alliance with Megaria. In "Siege," the Choten uses the Weapon of Mass Evolution on the Null Zone to evolve the creatures in the radius of its explosion in order to control them. He also uses a large saw made up of some Rumbling Terrasaur horns to open a portal to San Campion. In "The Evolution Will Not Be Televised," the Choten captures the Light Mystic so that he can have an endless battery source. When Raiden gets through to his father, the Saguru/Humonculon webs up the Choten. With his plans thwarted, the Choten escapes by banishing the Saguru/Humonculon.
* Joseph "Fingers" (voiced by Jason Marsden) - Joseph is a duelist who is nicknamed "Fingers" because of an injury in which he lost two of the fingers on his right hand following an incident with an unknown creature. He is an ally of the Choten, for whom he gathers corrupted creatures to help build the Choten's army. Joseph infiltrates the Duel Masters Temple as a newcomer acolyte in order to obtain some tablets. While the other Duel Masters are fighting Flametropus (who Fingers releases from the vault part of the Kaijudo Temple's creature stables), Ray, Gabe, Allie, and Master Chavez manage to repel Fingers, who manages to escape. In the fight against the Choten at his hideout, Fingers is sucked into the Creature World with the Choten, Master Nigel, and Heller.
* Heller (voiced by John DiMaggio) - Heller is a notoriously quick-tempered thug who works as a thief. One of the things he steals is one of the Choten's Duel Gauntlets. He discovers its power when he unknowingly summons Shaw K'Naw to Earth and uses it to commit a crime spree throughout San Campion. He encounters Ray, Gabe, and Allie, and Shaw K'Naw temporarily blinds Ray, then injures Master Nigel in a second encounter. When Ray comes to the museum, he uses Master Jaha's Fumes to combat Heller and Shaw K'Naw. When Ray and Fumes break Heller's gauntlet, Shaw K'Naw turns on Heller. Ray tells Shaw K'Naw that revenge isn't part of the Light Civilization's way and returns him to the Creature World. Heller is knocked out by Fumes as Ray leaves Heller for the police. While in jail, Heller is approached by the Choten, who "offers him a job," which Heller accepts. In the fight against the Choten at his hideout, Heller is sucked into the Creature World with the Choten, Master Nigel, and Fingers.
* Master Nigel Brightmore (voiced by John DiMaggio in a British accent) - A Duel Master, he is an expert on the Light Civilization and a master strategist. His creature partner is Ra-Vu, Seeker of Lightning. As the leader of the Council of Masters, Nigel guides the Order of the Kaijudo Duel Masters in their efforts to maintain the Veil to protect Earth from the Creature World and from the Choten. Unimpressed with Ray and his friends, he is appreciative of their talents (especially Gabe's intelligence). He was the Light Duel Master when the Choten was still in the order. By the episode "The Rising" Part 1, Master Nigel decides to side with The Choten because of his strong belief in the original Duel Master code of conduct between humans and Kaiju. He could not allow the creatures to enter Earth, and he would rather accept the Choten's flawed motivations than deal with the chaos that has resulted from breaking the code. Ray, Allie, and Gabe have violated the Duel Master code on several occasions in order to do what is good and logical, rather than what is lawful to the code. His attachment to the rules has blinded him to what is really important in life. As a result, he chooses to join the Choten. Master Nigel is defeated by Master Jaha and is sucked into the Creature World with the Choten, Fingers, and Heller. Afterwards, Gabe is elected to be Master Nigel's temporary successor due to his connection with Sasha, Channeler of Light, until other arrangements can be made. In the episode "Caught in the Spotlight", Master Nigel evolves Ra-Vu into Ra-Vu the Stormbringer so that the Choten can demonstrate the Evolution Serum's effect to Alex. During the fight at Carnahan Family house in the woods, Master Nigel is surprised to find that Ra-Vu has the power of speech in this form. Master Nigel secretly regrets having to evolve his creature under The Choten's orders. In "The Evolution Will Not Be Televised," Master Nigel turns against the Choten since Master Nigel only wanted order in the Duel Masters. This led to his fight with Master Tiera where both of them ended up falling into the transportation ley lines in the Duel Master Temple taking each of them to another location.
* Alexander "Alex" Carnahan (voiced by Andrew Kishino) - Alex is the father of Carny and helps to run the city of San Campion. Alex is continuously disappointed at Carny when he gets into trouble at school. When Ray plans to use Tatsurion the Unchained to set Alex straight, Tatsurion and Ray are surprised that Alex knows everything about them when Alakshmi and the Choten's henchmen arrive. Alex reveals that he is the Choten's largest benefactor and one of his silent partners. When Ray and Tatsurion the Unchained end up in the Fire Civilization with Carny, Alex is surprised that Carny has come with them. After Carny is returned to Earth, he returns to his dad, who decides that Carny is ready for his gift—one of the Choten's Duel Gauntlets. At the end of the episode "Boosted," the Choten introduces Alex to Nigel as his chief financial benefactor. He directs him to one of Alex's chemical factories, which provide Nigel with a chemical that he places in the Duel Masters' spy system so that they would not spot the Choten and/or his allies. In the episode "Caught in the Spotlight," the Choten discusses Alex's plot to be a war profiteer by mass-producing his Evolution Serum. After Lucy leaks footage of Carny and Simian Trooper Grash on the Internet, Alex tries unsuccessfully to reach Carny, and sends Fingers and Heller to bring Carny to him. When Ray fights hard against Fingers, Heller, and Master Nigel, Alex breaks up the fight with Sword Horned. He orders Carny into the car so that the Choten can have Carny return to his base to be further trained and disciplined.
* "Carny" Carnahan (voiced by Phil LaMarr) - Carny is a school bully who often picks on Ray, Gabe, and Allie. When Carny and his friends corner the three friends in an alley, Ray unknowingly summons a Rumbling Terrasaur, which scares off Carney and his friends. In the episode "Like Father, Like Son," it is revealed that Carny is verbally abused by his father Alex. When Carny ends up with Ray and Tatsurion the Unchained in the Fire Civilization, Carny and Ray form a truce in order to evade Lord Skycrusher's bounty hunters and return to Earth. After Carny is retrieved from the Fire Civilization by Master Nadia Lobachevsky and Master Benjirou Kimora, he runs off. Ray lets him go as he tells the two Duel Masters that Carny's dad is one of The Choten's benefactors. Carny returns to his dad, who decides that Carny is ready for his gift—one of Choten's Duel Gauntlets. In the episode "The Unbearable Being of Lightness," Carny is trained by Alakshmi in the operation of the Duel Gauntlets. When Carny plans to target Sasha, Channeler of Light, he ends up fighting Gabe. Carny is defeated by Gabe and gets away. In the episode "Caught in the Spotlight," Carny accidentally gets Simian Trooper Grash sighted by Lucy, compelling him to flee before his father can deal with him. While hiding out in the Carnahan Family's house in the woods, Carny is defended by Ray when Heller, Fingers, and Master Nigel target Carny. The battle is broken up by Alex, who has Carny sent to The Choten's base to be further trained and disciplined.
* Master Tiera (voiced by Kari Wahlgren in armored form, Alanna Ubach in normal form) - She was the Fire Duel Master before Master Hector Chavez and the girlfriend of The Choten. In "Duel Hard," Saguru receives a memory fragment from the Choten. In this memory fragment, Master Tiera is seen jumping off a cliff after her partner Meteor Dragon betrays her. It is presumed that she has perished while the circumstances of Meteor Dragon's betrayal are unknown. It turned out that she is alive and had been placed in a cursed mana-dampening armor when she tried to control the Fire Mystic. Upon resurfacing as a prisoner of Lord Skycrusher, she has taken Alakshmi in as an apprentice following the destruction of the Volcano Warship in the first part of the Fire Civilization's war with the Water Civilization. Both of them were recaptured a second time following the conflict at Black-Ridge Volcano. Lord Skycrusher plans to make use of Alakshmi and Master Tiera. In "Bring Me the Head of Tatsurion the Unchained," Master Tiera has trained Alakshmi to cross the Veil. Following Moorna's failure to destroy Tatsurion, Alakshmi uses her veil-crossing ability to get her and Master Tiera away from Lord Skycrusher before he can have Vorg cook Master Tiera. In "Unmasked," Master Tiera joins Alakshmi Verma when she steal a Choten Minion's transport and brings her to the Choten's ship as one of her attempts to free Master Tiera from her mana-dampening armor. When this was a success, Master Tiera stops Alakshmi from taking her revenge. It was revealed that Meteor Dragon "betrayed" Master Tiera when she was unable to control its evolved form and she was thought dead when she actually summoned a smaller creature to save her. Before the Fire Mystic placed a mana-dampening armor on Master Tiera where she remained in the Fire Civilization for 20 years, it repaired her damaged gauntlet. Following Alakshmi being taken out of the Choten's base by Master Isao, Ray, Gabe, and Allie, Master Tiera stays by the Choten's side. In "The Evolution Will Not Be Televised," Master Nigel turns against The Choten which led to his fight with Master Tiera where both of them ended up falling into the transportation ley lines in the Duel Master Temple taking each of them to another location.
* Choten Minions (Various Voices) - The generic foot soldiers of the Choten. The Choten Minions come in large numbers from everywhere on Earth. They always carry out the errands of the Choten.
===Supporting characters===
* Ken Takahashi Okamoto/Saguru (voiced by Andrew Kishino) - Saguru is a mysterious person with a missing right eye who has the knowledge to navigate around the Creature Realms, including the knowledge of hundreds of passages through the Realms. His creature partner is Humonculon. Because of his unknown past, Saguru is working for The Choten in exchange for The Choten's help in discovering his past. The first memory that Saguru recovers is when he came from Earth after he handed over the Sword of Fiery Cataclysm to The Choten. In the two-part episode "The Deep End," Saguru helps Ray, Allie, and Gabe get to the Water Civilization so that Ray can get his memories back from the Mother Virus after Choten's Memory Swarm removed Ray's memories. Once inside the capital of the Water Civilization, Gargle has the guards remand Saguru to the dungeon. During the group's escape, Ray has Saguru freed. While the guards are busy chasing after Ray's group, Saguru makes his way to the Mother Virus as Aqua Seneschal tells him that the Memory Swarm used by Choten is not associated with the Mother Virus. After The Choten fails to gain control over the Helm of Ultimate Technology, Saguru helps him and Aqua Seneschal escape the Water Civilization in exchange for his next memory. The second memory that he recovers is that he is a former Nature Civilization Duel Master and an old friend of The Choten. In the episode "The Nature of Things" Part 2, Saguru poses as a Snow Faerie in order to enter the Nature Civilization's tournament where the prize is the Shield of Unity. During the final round, Aqua Seneschal crashes the round and steals the Shield of Unity, causing Ray, Tatsurion, Saguru, and the other Nature Civilization creatures pursue him. After the Shield of Unity falls into the Darkness Civilization during the scuffle, The Choten is not pleased with Saguru failing in the tournament and crushes one of the Memory Swarms. Saguru realizes that The Choten is not the friend he knew in the past. Saguru is forced to work with him for his remaining memories. In the episode "Duel Hard," Choten sends Saguru to help Alakshmi and Heller hold up a bank, where the two pieces of the Helm of Ultimate Technology are held. Saguru succeeds in his mission, and Alakshmi and Heller fail. When Saguru asks why they have to fight the Duel Masters, The Choten tells them that they are misguided, and he gives Saguru the Memory Swarm that contains the memories about what happened the day that Master Tiera was betrayed by Meteor Dragon (the creature she has chosen), and the day when Master Toji lost part of his left leg to Snapclaw. The Choten also returns to Saguru his Duel Gauntlet. In the episode "Betrayal," Saguru accompanies The Choten, Alakshmi, Fingers, and Heller to attack Ray's apartment. When The Choten plans to have the apartment taken down, Saguru objects and secretly destroys the Summoning Inhibitor. Saguru saves Ray, Gabe, Allie, and Sasha, Channeler of Light when The Choten summons Flametropus to level Ray's apartment building and brings them to his place in the Nature Civilization. Saguru informs Ray that The Choten holds his memories hostage, and gives Ray the coordinates of The Choten's base in San Campion Bay, telling him that he was one of the Duel Masters. At the Nexus point of the Five Civilizations, Tatsurion the Unchained and Sasha, Channeler of Light collapse as Saguru saves the lives of the humans. Saguru gets Sasha, Channeler of Light away from the Nexus and claims the Heart of Light from her. He hands it over to The Choten, and is given the Memory Swarm that reveals the memory that he was once Ken Okamoto, married to Janet Pierce-Okamoto and that Ray is his son. Devastated to realize that via The Choten's using him he has betrayed his own child, Saguru retaliates, is knocked out by Trox and incarcerated. In the episode "The Rising" Part 1, Saguru uses Humonculon to break open his helmet and free Tatsurion. Aqua Seneschal intervenes and shoots Saguru, Tatsurion the Unchained, and Homonculon with the evolution serum where Humonculon's evolution binds him to Saguru. When Ray enters The Choten's hideout, he finds Saguru in his hybrid state (referred to in the cards as Humonguru) until The Choten arrives. Saguru rises to his feet and helps Ray fight a mind-controlled Tatsurion the Unchained. While Ray tries to get through to Tatsurion, Saguru deals with The Choten until The Choten uses the Shield of Unity to order Humonculon to throw Saguru back into the cargo bay. Crashing to the cargo bay floor, Humonculon is banished to the Creature Realm, taking Saguru with him, since they are bound together. In the episode "The Rising" Part 2, Saguru and Humonculon lie comatose at the shores of the Water Civilization as Saguru's body is placed in a special underwater suit before being dragged underwater by a Water Civilization creature. In "The King's Speech" episode, Saguru is revealed to be alive. He helps Finbarr get Ray, Gabe, and Allie to the Darkness Civilization when King Tritonus' is under The Choten's control. The Water Civilization creature that found Saguru in a coma works for Finbarr and it is revealed that Saguru has just awakened from a coma. Ray works with Saguru and Reef Prince Glu-urrgle to infiltrate the Choten's ship to expose The Choten's control of King Tritonus. After the failed mission, Saguru tells Ray that he cannot return to Earth, since Humonculon binding to him has made him more creature than human. Ray vows to find a way to return his father back to normal, which leads Ray to seek out each of the Creature Mystics to find one of them who might know a spell that can separate Saguru from Humonculon. Over time, the fusion of Saguru and Humonculon causes more of Humonculon to slowly take over Saguru's mind and body. In "Bargain," The Choten tricks Raiden into giving him the Spell of Liquid Compulsion from the Water Mystic in exchange for the antidote for the Evolution Serum to be used on Saguru (who is almost transformed into a humanoid spider-like creature). Unfortunately, the antidote doesn't work on human/creature hybrids as The Choten uses the spell to take control of Saguru much to the dismay of Master Nigel Brightmore and Master Tiera. During that time, Saguru is seen trying to fight Humonculon's control. In "The Evolution Will Not Be Televised," Saguru fights the Choten's control and helps to subdue him. Though the Choten escapes upon banishing Saguru. By the end of the episode, Raiden summons Saguru and Humonculon where he uses the power within him to restore both of them to normal. Afterwards, Ken is reunited with his family.
* Janet Pierce-Okamoto (voiced by Grey DeLisle) - Janet is Ray's mother. The episode "Betrayal" reveals that Janet was once a Kaijudo practitioner when Choten and his minions laid siege to Ray's apartment. After Ray frees Janet from a Cyber Virus, she tells Ray that his father was a Duel Master and that he taught her how to duel in the Nature Civilization where Ray was born. In the episode "The Rising" Part 1, Janet tells the Duel Masters about Master Ken Takahashi Okamoto, the Nature Duel Master before Master Kimora. Master Ken was Janet's husband who married her while he was a Duel Master. While Janet was pregnant with Ray, The Choten and his forces attacked their home. Master Ken's gauntlet was damaged in the fight, but he was able to open the Veil and took Janet with him to escape. Janet gave birth to Ray in the Nature Civilization and when Ray was a toddler, Master Ken was able to repair the Gauntlet. As the family was preparing to return to Earth, The Choten found them and attacked. Master Ken opened the Veil to Earth and Janet and baby Ray went through, but Master Ken closed the Veil to prevent The Choten from following them. In the episode "The Rising" Part 2, Janet pilots the Rumbling Terrasaur when she joins up with the other Duel Masters.

* Piper Underhill (voiced by Kari Wahlgren) - Allison's mother. A picture of her with her husband and Allison is seen on the yacht Allison's father maintains. In an encounter with the Choten in episode 16, Allison is told by him that her mother ran away from home and that her father was weak. Piper's fate is currently not clear. In "Duel Hard", it is revealed that Allison does not like her mother. In the episode "Heart of Darkness" Pt. 1, it is revealed that Allison was young when Piper ran away. In addition, Megaria the Collector assumed Piper's form in order to get Allie on her side, but Megaria ultimately fails. By the end of the episode "Heart of Darkness" Pt. 2, Allison makes peace with her mother by peeling the packaging tape off from Piper in the family picture on her bedroom wall. In "Gargle, Gargle, Toil and Trouble," Piper returns into Allie's life and tries to reconnect with her. Arthur Underhill later convinces Allie to give her a chance where she left Allie a present containing a mask.

Her creature partner is Razorkinder Puppet of Miasma Pit. Alakshmi is a formidable threat to the effort of keeping the balance between human and creature kind in place. She is a very single-minded Kaijudo duelist, cool and calculating with a definite dark side. Not only is Alakshmi skilled in battle and a serious challenge for the heroes, but her beauty is intimidating and distracting to the boys, which is very irritating to Allie. In the episode "Heart of Darkness" Part 2, it is revealed that Alakshmi's mother Padma may have sold Alakshmi to The Choten. In the episode "Heavenly Creatures," Alakshmi has personal issues with the Light Civilization, because one of its creatures destroyed her ancestral village. In the fight against The Choten at his hideout, Alakshmi turns against The Choten in order to reverse the mana flow. Following the fight to restore the Veil, Alakshmi is sucked into the Creature Realm and is a prisoner of the Fire Civilization. During Alakshmi's time as a prisoner of Lord Skycrusher, she is trained by a full armored, hooded robed human that turns out to be Master Tiera following the destruction of the Volcano Warship in the first part of the Fire Civilization's war with the Water Civilization. Both of them are recaptured following the conflict at Black-Rim Volcano. Lord Skycrusher plans to make use of Alakshmi and Master Tiera. In "Bring Me the Head of Tatsurion the Unchained," Alakshmi has been used by Lord Skycrusher to summon fleeing spies for captures while learning the veil-crossing spell. She is then ordered to use Moorna into leading Tatsurion into a trap by capturing Headstrong Wanderer (though Alakshmi did tip of Ray beforehand). After Moorna's plot to have Brutalus get revenge on Tatsurion didn't work, Alakshmi used the veil-crossing spell to rescue Master Tiera as they successfully escape from Lord Skycrusher's castle. In "Unmasked," Alakshmi steals a Choten Minion's transport and takes Master Tiera to The Choten's ship in order to use the technology their as an attempt to get the mana-dampening armor off of Master Tiera. Following a power surge, Alakshmi arrives and uses Razorkinder to pin down the Choten in order to get her revenge on him. This was thwarted by Master Tiera as Master Isao gets her and the children away from the Choten. In "Dueling Partners," Alakshmi comes to the Duel Masters Temple for help when she is being hunted by the Choten's minions. Alakshmi helps Allie when it comes to stopping Master Nigel Brightmore into using a Cyborg Samurai with a Rumbling Terrasaur horn on its drill bit to break through the Veil and flood the Darkness Civilization. After that plot was thwarted, Alakshmi ends up becoming a probationary acolyte of the Duel Masters Temple.
===Creatures===
The following creatures, which come from the five different civilizations, were either originally featured in the original Kaijudo franchise in recolored and renamed form, or are exclusive to this franchise.
====Creature Partners====

It's revealed that his mother Headstrong Wanderer is from the Quillspike Tribe of the Beast Kin and his father Napalmion the Conquering is from the Armored Dragons. His brothers in his Quillspike family, Razor-Hide and Prickle-Back, nicknamed him Bare-Bottom (most likely a reference to the fact that he has so few quills). He is also revealed to be a fugitive of the Fire Civilization with a bounty on his head after he attacked a dragon that was attacking the Nature Civilization (more specifically the Quillspike Tribe). Before the final attack on The Choten's base, Tatsurion is captured by the Choten's summoning machine. He is later injected with the Choten's evolutionary serum, which evolves him into Evo Fury Tatsurion. In this form, Tatsurion sprouts wings that grant him flight.

The progress of the further combination causes Humonculon to slowly take over Saguru's mind and body. Eventually, the final process turns both of them into a humanoid spider-like creature.

====Creature Monarchs====
The Creature Monarchs are the rulers of the five Creature Civilizations. The Creature Monarchs are shown to be immune to the effects of the Null Zone (a neutral area between the Five Creature Civilizations that can drain mana from any creatures). They banded together with Five Wizards when a war between the humans and the monsters threatened both worlds. The Creature Monarchs sacrificed some of their Mana so that the original Duel Masters can create a veil that has since separated the human and creature worlds. With little energy left, the Creature Monarchs fell into a deep slumber. It appears the plan was originally to allow the Creature Monarchs to recover their strength and awaken before sending them across the Veil so they might rule their civilization again. At some point in the Creature Monarchs' history following the two worlds being separated, the Order of the Kaijudo Duel Masters betrayed the Creature Monarchs' trust where they periodically siphoned off their mana and kept them in hibernation for a millennium as experienced when Ray used his mana on the Fire Civilization's King. This information surprised Master Hector Chavez and Master Benjirou Kimura. If the Veil collapses, the Five Creature Monarchs will be reawakened and continue what they began thousands of years ago. The Choten later awakened the Creature Monarchs in a plot to bring down the Veil. This plan was thwarted when the Duel Masters and their allies concentrated their Mana to repair the Veil and send the Creature Monarchs back to the Creature World.
* Infernus the Immolator (voiced by John DiMaggio) - A giant Armored Dragon that is associated with the Fire Civilization. His wings are large enough to shade an entire city in their shadow.

When Allie claims the Sword of Fiery Cataclysm, Ray returns it to Infernus the Immolator. Infernus remembers Ray and agrees to duel with him to stop the Choten. When the Veil is restored, Infernus the Immolator is returned to the Fire Civilization as he tells Lord Skycrusher to send word to all Fire Civilization Creatures that they are going to war. Following the incident with the Water Civilization in the first part of the war, Infernus the Immolator has pardoned Tatsurion the Unchained of his previous crimes in return for saving Lord Skycrusher from his falling volcano warship and for Ray returning his sword.

Upon being awakened by the Choten, King Tritonus is summoned to the Choten. When the Veil is restored, King Tritonus is returned to the Water Civilization.

The Choten even used King Tritonus to form the Loyalty Police, had Milporo incarcerated, and Reef Prince Glu-urrgle exiled from the Water Civilization.

Due to the seeds of suspicion sewed by the Choten, Queen Kalima decides to go to war with the Light Civilization and sets up a foothold in San Campion. In "Brainjacked", Queen Kalima starts her campaign to invade San Campion with Gregoria leading the invasion. Allie leads Ray, Gabe, and Master Jaha into a meeting with Queen Kalima where Allie uses the Cloak of Dark Illusion to get Queen Kalima to listen to her. With help from Sasha, Allie convinces Queen Kalima to call off the invasion where Allie returns the Cloak of Dark Illusion to her. Afterwards, Queen Kalima shows some respect for Allie and calls off her invasion of San Campion, for now. She is referred to as Queen Kalima of the Infinite Dark in the TV series.
