Humans

Kyoya Gaen

Dragon Ein (Season 1), Dragon Zwei (Triple D), Dragon Drei (Triple D)

Voiced by: Satoshi Hino (JP), Ben Rose (EN)

The young head of the Gaen financial group and leader of Disaster. His buddy is Azi Dahaka of Darkness Dragon World. He used to play a Dragon World deck in the past. His current deck however is special. It uses the Flag Card "Dragon Ein", which allows him to use any card with with a Dragon attribute.


  • Affably Evil: He is never impolite, even when telling Nobari that he's no longer of use.
  • Badass Longcoat: Wears one when the Disaster Force is activated.
  • Big Bad: As the leader of Disaster, he is this for the first season. He's also this for the third season as well.
  • Deity of Human Origin: What he sought to become in DDD. He achieved it briefly.
  • Evil Cannot Comprehend Good:
    • His master plan to open a portal to Darkness Dragon World by combining the power of his and Gao's Disaster Forces fails because he doesn't realize that Future Force is a fundamentally different ability from Disaster Force; Gao's Future Force seals the portal instead of opening it.
    • Azi Dahaka points out that his unwillingness to divulge his entire plan to his buddy meant his aspirations, those involving buddyfighting and Godhood, meant they never fully had a chance of being completed.
  • Fusion Dance: The end result of his Project Triple D has him forcibly assimilate Azi Dahaka in order for Kyoya to become a deity.
  • Godhood Seeker: His plan during the third season is to become a deity. He eventually succeeds, at least until he's beaten by Gao again.
  • Heel–Face Turn: After losing to Gao he accepts the world isn't ready to change and becomes friends with Gao. Subverted when Hundred reveals he didn't change at all.
  • Hellish Pupils: His pupils are reptilian-looking slits. Bonus points for his eyes already being red.
  • Hijacked by Ganon: Tries to pull this near the end of Hundred by expoiting the Yamigedo crisis and come off of it as the hero. It backfires and causes Yamigedo to become even more powerful.
  • I Am Not Left-Handed: Thought Kyoya would be done for once the twenty Life he has because of Zwei's effect are depleted ? Nope, here comes Dragon Drei, giving him an additional 5 Life to continue the fight.
  • Karma Houdini: He doesn't suffer any repercussions for his actions during the first and second season despite his plans being foiled. He's finally arrested in DDD, where he made it clear on live television his plans to rule the world as a god.
  • Never Recycle Your Schemes: Subverted. Near the end of Hundred he's trying to pull off coming off as the Hero of the crisis, but this time he isn't the one who's causing it in the first place.
  • No-Sell: Anticipated that Tasuku was just pretending to be on his side, and modified Tasuku's Dark Core Deck Case so that its Disaster Force would be ineffective on Darkness Dragon World monsters.
  • Oh, Crap!: When Drum gets a new form through the Future Force. Granted, that is the proper response to that sort of thing.
  • Red Eyes, Take Warning: Has them by default, but they gain slit pupils with the Disaster Force.
  • Screw the Rules, I Make Them!: Does this fairly blatantly during the Gaen Cup. Namely, he allows the Konmae Brothers to compete despite the tournament supposedly being for children, handwaving it with the excuse that they might have reformed and because he said so. He also allowed Tasuku to compete as the Purgatory Knight despite his true identity being unknown at the time.
  • Story-Breaker Power: He has the Dragon Ein Flag card, which allows him to use any card with a Dragon Atribute, and start the fight with 12 Life Points, though in exchange his starting hand is four. He also has the "Dragon Throne" set spell, which not only prevents any of his Item and Spell cards including Dragon Throne itself from being destroyed, nullified, or returned to his hand, it allows him to increase his max monster size by 4 and summon Size 4 Monsters!
    • Does it again with the Dragon Zwei Flag card. This time, it allow him to use any Dragon Attribute Monster instead which means the Dragon Throne spell does not come into effect and he still starts off with 4 cards. The Game Breaking part comes with his starting life which is 20.
    • And should that massive amount of Life be depleted, Kyoya can use another Flag card, Dragon Drei, to give himself an additional 5 life at the cost of all the cards on his field. This may not sound too bad, except that by having this flag lets him transform into Demonic Dragon Deity of the Black Sun, Gaen, a size 10 monster with 15000 Power, 12000 Defense, a critical of 5 that cannot be destroyed, returned to the hand or have its abilities nullified. On top of that it also prevents the opponent from drawing during their next turn after this card is transformed into, destroys any monster they have when it attacks and allows Kyoya to discard any two Size 3 monsters he has in hand to gain another 5 Life.
  • Tempting Fate: When his victory is all but assured, he taunts Gao by saying even he can't control the future. Immediately afterward Gao's future self gives Gao the card he needs to win the battle through the power of the Future Force.
  • The Bus Came Back: Though only in a brief cameo, Kyoya is shown to be watching Gao's match in episode 26, stating that just as he was supposed to lose to Kyoya but won, he would do so in his fight with Ikazuchi. As Kyoya predicts, he does.
  • This Cannot Be!: He's shocked when Tasuku overcomes the Dark Core he gave to him.
  • Villainous Breakdown: Sort of. His plans were based on Gao's potential of using the Future Force which he believed was the same as his Disaster Force, when he discovers that the portal is closing he finally loses his calm composure.
  • Villainous Friendship: Claims that the other members of Disaster are the closest he has to friends, with Rouga being such for the longest. That said, he sees them more as means to an end than anything else. For all his manipulations of Rouga, the two seem to finally be on good terms as of the end of Triple D.
  • Villain with Good Publicity: He has a good reputation as the head of the Gaen financial group and makes use of it during the Gaen Cup to make the public accept the Dark Core and Disaster Force. It helps that he's charismatic enough to defuse tensions with the audience, and specifically made an effort to make sure the fights were entertaining for the audience. This is why he's remained a Karma Houdini for so long.
  • You Have Outlived Your Usefulness: After Terumi loses her fight against Tetsuya, he has Sofia takes her buddy and memories away.
    • Does nothing to help Sueroku and Seiichi when the Buddy Police try to regain control, citing he doesn't need the Buddy Police anymore now that Tatsuku has joined Disaster.
    • Episode 59 has him doing this to Rouga of all people. A flashback reveals Kyoya made a mistake during a Buddyfight, calling Phalanx Dragon when he didn't have enough gauge to pay it's cost, but Rouga stayed silent. Turns out it was intentional, as he wanted to test him. Now that he's calling him out on his master plan, Kyoya states that Rouga is no longer the friend he knew and cuts all ties with him, raising heavy implications that he only used Rouga because he wanted someone who would blindly follow orders without question.

Rouga Aragami (Wolf)

Danger World

Voiced by: Minoru Hirota (JP), Daegan Mann (EN)

An 8th-grader at Aibo Academy who is ranked first in his grade who believes that victory is the only thing that matters. He works alongside the student council president for a monster called Azi Dahaka and its mysterious master.

He uses a Danger World deck, focusing on Armorknights. His buddies are Armorknight Eagle and Armorknight Cerberus, who later evolved to Armorknight, Cerberus "A". In Buddyfight Hundred, he is searching for the eighth Omni Lord and once the latter is awakened, includes him in his deck. In Buddyfight DDD, he enters the WBC knowing the national round is one an island Kyoya owned and told him was important. He uses a Tyrant deck now.


  • Beneath the Mask : His reason for joining Disaster and becoming a criminal fighter, it's all for his friend, Kyoya.
  • The Bus Came Back: Rouga does this at least once per season.
    • First, at the end of episode 24 of the first season.
    • And again in Hundred when Tasuku investigates the Buddyfight Club, finally staying around after adding Grangadez to his deck.
    • And during DDD at the start of the WBC Japan tournament.
  • Childhood Friends: With Kyoya who he thinks of as a brother.
  • Curbstomp Battle: Deals one to Tetsuya. Gao quickly pays him back with a One-Turn Kill.
  • Even Evil Has Standards: He responds with disgust when Raremaro sneaks a hate card in Kemura's deck to specifically target Genma, saying that it was "a cheap way to win".
    • He even prefers to utterly crush his opponent as opposed to doing underhanded tactics, as well as resorting to solid strategy if needed.
  • Evil Sounds Deep: His voice by far, is one of the deepest voice among Buddyfight's human characters, only outdone by members of the Seifukai.
  • Forced into Evil: In DDD, he attempts to have Kyoya abandon his plans but is forced into a Buddyfight with the condition that Rouga will become Kyoya's Friend if Rouga loses. He is then Curbstomped by Kyoya offscreen. Official material shows that Rouga has now returned to using his Wolf mask.
  • Friendly Enemy: During episode 37, it is shown Rouga is disturbed at the fact that Kyoya wants Gao to join Disaster. And then episode 43, he helps Gao by telling him Kiri's location.
  • Heel–Face Turn: After Kyoya throws him away. It sticks during Hundred especially as one of the Omni Lord users. He is however Forced into Evil in DDD by Kyoya.
  • Hot-Blooded
  • Paper-Thin Disguise: As Wolf. Tasuku easily see through it; the only reason the Buddy Police can't arrest him is a lack of evidence and the fact that his registered Buddy is different.
  • Put on a Bus: After losing to Gao in episode 6, he dropped out of Aibo Academy and hasn't made any appearence ever since.
  • Second Place Is for Losers: His attitude to Buddyfighting, which isn't as expressed as often nowadays.
  • Undying Loyalty: To Kyoya, who is more than willing to use and manipulate Rouga's feelings. Rouga is surprisingly forgiving of this.

Magoroku Shido

Darkness Dragon World

Voiced by: Kenta Zaima (JP), Cole Hanson (EN)

The president of Aibo Academy's Middle School Division student council. He works alongside Rouga and Sofia for Azi Dahaka. In Buddyfight 100, he and Sofia are now working for Ikazuchi, with Shido taking on the identity of Death Shido.

He uses a Danger World deck and an Ancient World deck but his true deck is a Darkness Dragon World one focusing on the Death monsters and their Shadow Dive ability. His Buddies are Bluechase Dragon, Garg (Danger) and Silver Dragon, Adelaide (Ancient), but his real Buddy is Death Ruler, Gallows (Darkness Dragon). In Hundred, he also uses several different deck when partnered with one of the Hundred Demons under the guise of Death Shido, before going back to His Darkness Dragon World deck that mixes Death and Deep monsters.


  • Absurdly Powerful Student Council: It's gone to his head. He uses his powers to order a check of the Seifukai's deck so that he has the advantage during the ABC Cup.
  • Butt-Monkey: His schemes usually end in failure, he lost all but two of his fights, and his own buddy monster doesn't respect him.
  • Cheaters Never Prosper: He uses various unfair methods in order to ensure that he (and by extension the middle school) will be the winner of the ABC Cup. It doesn't work.
    • His father tries to cancel his fight with Zanya during the Gaen Cup right as the latter is about to finish Magoroku off. Apparently Kyoya didn't agree with the decision as Zanya's finisher hits both Magoroku and his old man.
  • Child Prodigy: Claims to be one... but he really isn't.
  • Demoted to Extra: In DDD.
  • Dirty Coward: So very much.
  • Epic Fail: His match against Zanya in the Gaen Cup. It starts with him promising a one-turn victory, but one Gilligan Cut later, Zanya is about to finish him off. Paruko even calls it an epic fail.
  • Extreme Doormat: In Hundred, where he is constantly pushed around by Sofia, the Hundred Demons and even Davide.
  • Hero Killer: Manages to defeat Genma with his true deck, although it should be noted that his playstyle specifically counters Genma's and that his opponent had never heard of the world Shido was using before.
  • Hoist by His Own Petard: Noboru beats him with the very card Shido gave him as a bribe last year.
  • Humiliation Conga: First he loses to Noboru (using the card Shido gave him last year), then all the middle school representatives are beaten by the elementary school, then Genma escapes his prison and drags him out in front of the school to be punished, and he finally gets curbstomped by Genma.
    • His Buddyfight against Captain Answer (actually Genma in disguise) is one that sees every one of his "strategies" fail, him getting bitch-slapped twice by Genma and blasted off a building by Sofia, only to be saved by Genma before he hits the ground, all of which happened on his birthday.
  • I Just Want to Have Friends: Genma declares in his in "The Reason You Suck" Speech to Shido, in that he wants power and friends. The issue Genma had is that he doesn't care about the students, and only became council president for these reasons.
  • Long-Haired Pretty Boy: His hair grows longer when he activates the Disaster Force. His dad doesn't think it's a good look for him.
  • The Mole: He was spying on Ikazuchi on Kyoya's orders.
  • Oh, Crap!: Near constantly in Hundred.
  • Smug Snake: Thinks very highly of himself and looks down on everyone. His track record quickly shows that he has little ability to actually back up his claims.
  • Spoiled Brat: It's obvious that his father hasn't been a good influence on him. He expects to win every time, has a very over-inflated opinion of himself and looks down on those around him, much like his old man.
  • Student Council President: Of Aibo Academy's middle school division.
  • Verbal Tic: In the japanese version, he always ends his phrases with desu-shi.
  • Villain Decay: Went from a critical threat in the ABC Cup to the weakest villain in the show.
    • It's Zig-Zagged with him though. On one hand, see Hero Killer above, when he fights using his own deck and has his head on straight, he's very scarily competent due to the deck's control aspects. Another good example is his fight with Gratos, where he manages to utterly play him using cards that switch Gratos' positions around along with Shadow Dive, before finishing him by forcing him to exhaust his soul, before using his new Impact card that can revive units.

Sofia Sakharov

Her buddy is Star Celestial, Astraios and she uses a Legend World deck revolving around the Star attribute. In the second season, she also used different deck when partnering with some of the Hundred Demons under the guise of Death Shido. She later obtains a Star Dragon World deck from Kyoya and gets the Inverse Sixth Omni Storm Lord, Catastrophe Cord to use as her buddy.


  • Chekhov's Gunman: Originally starts off as Shido's quiet sidekick. Come Shido's losses in the ABC Cup, she becomes more active, and eventually ditches Shido.
  • The Corrupter: She tempts Genma, Kiri, Shosetsu, and Gao with a Dark Core deck case and puts Doai into a berserk rage with one.
  • The Dragon: She serves as one to Kyoya. Though she later works for Ikazuchi in Hundred she's revealed to still be working for Kyoya.
  • Evil Counterpart: To Tasuku. Her use of the Disaster Force opposes Tasuku's Future Force. Hammered home in Hundred where she gets Catastrophe Cord, Variable Cord's evil clone.
  • Hyper-Competent Sidekick: She's this to Shido. Until she leaves the student council.
    • She becomes this again when the two start working for Ikazuchi.
  • Karma Houdini: Unlike Rouga, she doesn't even bother with a Paper-Thin Disguise, yet she suffers no repercussions for her actions.
  • Kick the Dog: She shows no remorse for (and even relishes in) teleporting Gao and Drum into the air, where they could fall to their deaths. She also has no qualms taking Terumi's Buddy away right after they started bonding.
  • Laser-Guided Amnesia: She has the ability to erase memories using Disaster Force.
  • The Mole: She was spying on Ikazuchi on Kyoya's orders.
  • Psychotic Smirk: The rare occasions that she does show emotion are usually her doing this.
  • Star Power: Her deck is comprised of cards with the Star attribute.
  • Stating the Simple Solution: In a passive way. Points out that as long as Death Shidou is the fighter, they'll never win, motivating Izkauchi to get off his ass
  • The Stoic: She rarely shows emotions.
    • Not So Stoic: Asmodai is able to push her buttons enough to make her absolutely flip.
  • Verbal Tic: Her frequent use of "Da" becomes this in episode 41 of Hundred while she's under the control of Yamigedo.
  • Villain Override: In episode 41 of Hundred, Yamigedo takes control of her to force her to fight Tasuku.
  • White Hair, Black Heart: One of the three members of Disaster with white hair and one of its most dangerous members after Kyoya.

Elf Kabala

One of the members of Disaster, Kyoya's group. He is a teacher at Aibo Academy.

Terumi Kuchinawa

Legend World

Voiced by: Mai Todo (JP), Angie Beers (EN)

One of the members of Disaster, Kyoya's group. She also attends Aibo Academy and is the new Student Council vice-president. She uses a Legend World deck with cards based on Greek Mythology, including her buddy Gorgon Three Sisters, Medusa.


  • Amnesiac Lover: Has no memories of Tetsuya following her memory wipe, although she does decide to watch his match against Sofia.
  • Classical Mythology: Her deck contains cards named after characters from greek myths.
  • From Nobody to Nightmare: According to her backstory, this was what happened when she joined Disaster.
  • Known Only by Their Nickname: "Terumi Kuchinawa" is actually a name Kyoya came up with, because her real name wasn't impressive or flashy.
  • Laser-Guided Amnesia: Has her memories of her time with Disaster erased by Sofia after she loses to Tetsuya.
  • Loss of Identity: When her memories get erased by Sophia.
  • Luminescent Blush: Blushes after looking at Kyoya.
  • Serious Business: How she treats Buddyfight. This is because Buddyfight gave her an identity; she feels that she would have nothing if she wasn't good at this game. Her biggest piece of character development comes from Tetsuya and Asmodai teaching her that Buddyfight should be fun, and that he doesn't have nothing when she has friends.
    • Both of those traits are lost when she loses her memory.
  • Ship Tease: With Tetsuya.
  • Star-Crossed Friends: With Tetsuya.

Davide Yamazaki

Darkness Dragon World

Voiced by: Akio Suyama (EN), Chris Cook (EN)

One of the members of Disaster, Kyoya's group. He uses a Darkness Dragon World Deck, focusing on Black Dragons monsters such as his buddy Death Dragon, Deathgaze Dragon.


  • Cheaters Never Prosper: He still couldn't defeat Gao despite cheating.
  • Combat Pragmatist: Even when he's not cheating, his deck centers around countering strategies by directly destroying creatures, items and even set spells.
  • The Corrupter: He's the one who gives Kiri his Dark Core deck case and gets him to accept its power.
  • Evil Counterpart: To Rouga as of Hundred due to them both using Danger World decks at the time. He also gets Grangadez's evil clone Devilgadez.
  • Hero Killer: Easily defeats Kazane, not helping in universe that Darkness Dragon World was just recently discovered. It wasn't until episode 40 that cards from the world start appearing, so nobody knew what it was capable of, and there's the fact he cheated during the fight.
  • Jerkass: He is rude and insulting to everyone. Even deliberately tripping the Castle Card Shop owner and then mockingly apologizes. He even mocks Gao and his deceased brother! Apparently he does this to all his opponents so he can distract them while he cheats. Tasuku even says someone like him has no business being a Buddyfighter. Also is willing to kill as mentioned below.
  • Jerk Ass Has A Point: Despite being a cheater as well as an all-around unpleasant person, he does have a point when he says that Gao is the reason that Kiri turned evil.
    • When Tasuku calls him out about destroying his own monsters, he retorts that it's not so different from Tasuku turning Jack into a mindless weapon.
  • The Power of Creation: Has enough control over the Disaster Force to make his cards' effects real.
  • Sore Loser: After Gao defeats him, instead of keeping his word and telling him what he knows about what happened to Kiri, he instead activates Disaster Force and tries to kill Gao! He would have succeeded if Gao didn't suddenly gain access to Future Force.
  • The Bus Came Back: He returns in episode 31 of Hundred as an Evil Counterpart to Rouga.
  • You Have Outlived Your Usefulness: He is not above sacrificing his own monsters if it means, he'll win the fight. His impact card even requires him to do so in order to be cast.

Gremlin/Retsu Omori

Darkness Dragon World

Voiced by: Kenjiro Tsuda (JP), Joel Crichton (EN)

One of the members of Disaster, Kyoya's group, who serves as their deckbuilder. He uses a Darkness Dragon World deck with a focus on cards with the Deep attribute such as his buddy Black Dragon of Demise, Death Tallica.


  • Boring, but Practical: It's been called out as this In-Universe, to everyone's frustration. Ultimately how his Deep Deck and Buddy Death Tallica are, using Tallica's special Soulguard note  and Double Attack.
  • Deadpan Snarker
  • Evil Counterpart: As Disaster's deck builder, he is this to Baku. They are also cousins. Also, while Baku builds decks to suit the Buddyfighter, Gremlin wants Fighters to play suited to the decks he builds.
  • Evil Redhead: He has red hair and is one of the antagonists.
  • Mister Exposition
  • Pride: The part of his personality that his dark core amplifies is the pride he takes in his work as a deck builder. As a result, he is arrogant and condescending toward regular Buddyfighters.
  • Only Known by Their Nickname: 'Gremlin'. Though his real name is Retsu.
  • "Stop Having Fun" Guy: He gets really prissy when Buddyfighters don't play their decks like he wants them to.

Monsters

Demonic Demise Dragon, Azi Dahaka/Great Demonic Dragon of Demise, Azi Dahaka/Black Sky Sun Dragon, Azi Dahaka Daeva

Voiced by: Kinryuu Arimoto (JP), Tony Valdez (EN)

Kyoya Gaen's Buddy. A demonic dragon from Darkness Dragon World who is working with Kyoya to usher in a new world. He is unique among monsters in that he is size 4.

In Triple D, he is shown to have a connection to Bal. This is due to the fact that he fought Balle Soleil on Earth centuries ago and considers his arch enemy. After being defeated by Gao and Bal, Kyoya upgrades him to Great Demonic Dragon of Demise, Azi Dahaka. After training during the battles of the World Buddy Cup and against Gaito and Abygale, he becomes Black Sky Sun Dragon, Azi Dahaka Daeva.


  • Alliterative Name: Demonic Demise Dragon.
  • Archenemy: To Bal. When one of them defeats the other, they both hibernate until it is time for them to fight again.
  • Badass Boast: Gives these every time Kyoya calls him.
  • Beam Spam: Its attack is one that destroys all monsters and items in play due to its Erasure Of History ability.
  • Belly Mouth: Has a mouth full of razor-sharp teeth which is part of a face that covers his entire torso.
  • But Now I Must Go: After being defeated by Gao and Bal, he has to hibernate until it's time for them to fight again.
  • The Dragon: Seems to be this very literally to Kyoya Gaen.
  • Dragons Are Demonic: It's in the name and he's got the personality to match.
  • Evil Sounds Deep: Very deep.
  • Eyes Do Not Belong There: Azi Dahaka Daeva has eyes everywhere.
  • Four Is Death: The only size 4 monster in the series.
  • Large Ham: All of his lines are pure ham.
  • Named After Someone Famous: Azi Dakaha is the alternate name of an evil figure known as Zahhak in Iranian mythology.
  • One-Winged Angel: Black Sky Sun Dragon, Azi Dahaka Daeva barely even looks like a dragon anymore.
  • Our Dragons Are Different: Has three heads.
  • Purple Is Powerful: The most powerful Buddy Monster in the first season is reddish purple. His second form is more of a bluish purple.
  • Red and Black and Evil All Over: Azi Dahaka Daeva's color scheme.
  • Red Eyes, Take Warning: Has two red eyes on each head and another pair on his chest regardless of form.
  • Sealed Evil in a Duel: His battles with Balle Soleil are apparently this. One wonders why nobody has found a more reliable way to contain him, since he's caused mass extinctions on the occasions that he's won.
  • Sleep-Mode Size: His mini form, insofar as it can be called such, is just smaller versions of his three heads floating next to each other.
  • Spikes of Villainy: He is absolutely covered in spikes.
  • Story-Breaker Power: Its Attack and Defense are 10,000 each. That's the not even the worst part, when it attacks, it hits all monsters on the enemy fighter's field, the enemy fighter, and if it deals damage, destroys the opponents currently equipped item card. Destroying him just allows Kyoya to equip the item card "Demonic Demise Sword, Aqulta Gwaneff" from his deck, which has 12,000 Power, a Critical of 6, nulls Soulguard and makes him immune to solo attacks.
    • So Last Season: In the first episode of Triple D', he gets curbstomped by Bal, while the new Impact Monster machinic, combined with it's own No-Sell of Null effects, bypassed Aqulta Gwaneff's effect.

Armorknight Eagle

Rouga's official Buddy, though he takes a backseat to Cerberus. An Armorknight from Danger World


Armorknight Cerberus/Armorknight Cerberus "A"/Tyrant Cerberus

Rouga`s true partner and closest friend. An Armorknight from Danger World.


Death Ruler, Gallows/Gate Guider, Gallows Gestus/Bone Master, Rebel Gallows

Voiced by: William Scott (EN)

Magoroku Shido's Buddy. A skeletal, serpentine demon that has absolutely no respect for Shido. He was eventually upgraded to Gate Guider, Gallows Gestus as a side effect of Yamigedo's presence. As of X, he has once again obtained new power and become Bone Master, Rebel Gallows.


  • Dem Bones: He's some kind of serpentine skeleton, with the exception of his Rebel Gallows form.
  • Giggling Villain: Constantly gives an evil chuckle, which also serves as his Verbal Tic.
  • People Puppet: As Rebel Gallows, he has the ability to force the opponent's monster in the center to attack their own player which in the anime is shown as him using marionette strings to take control of said monster.
  • Took a Level in Badass: Gets an upgrade as a side effect of Yamigedo's power. Appaers to have taken another one between seasons by becoming Rebel Gallows.
