Season 1
Gargantua Punisher Entity
An mysterious entity that only appears to those who receive the Gargantua Punisher card. All that's seen of it is a pair of draconic eyes against a starfield. It also has some connection to Tasuku, who first used the card.
- Enigmatic Empowering Entity: With one exception, it only appears when someone receives the Gargantua Punisher card, which is unique in-universe. The one exception is when it appears in a Bad Future to heal Jack and power up his Deadly Upgrade into something stronger and safer to use. Its identity is never revealed, but it's clearly not Garga, who originally wielded the sword in the distant past.
- Supernatural Gold Eyes: All we see of it are draconic eyes with gold sclerae.
- The Chooser of the One: To Tasuku, whom it refers to as the "young boy of destiny." This is never really elaborated on.

A trio of criminal fighters who try to steal cards. Akaoni and Aooni are first introduced being chased down by the Buddy Police. Kurooni is introduced as a third member of their team in the Gaen Cup.
Akaoni's Buddy was Axe Dragon Dorcas before he got arrested by Tasuku. Aooni's Buddy Clash Dragon Gaelcorga ditches him before his fight with Noboru. Kurooni gets Sibling Dragon Foonbaltes as a temporary Buddy during Buddyfight Hundred. All three of them use Danger World decks.

- Fat Bastard: Kurooni.
- Red Oni, Blue Oni: Akaoni is more hotheaded that Aooni. Their names and appearances even reflect this trope.

- Affectionate Nickname: He calls Drum and Gao "Drumkins" and "Gaowow" respectively.
- Ambiguously Gay: He's rather effeminate and extremely clingy and friendly with Drum. His card's flavor text also mentions him looking for "his prince." As well, his appearance in the Japanese Buddyfight Card of the Day on the official website refers to him as a "her".

- Detect Evil: His hair lets him detect Hundred Demons.
- Elemental Punch: Capable of doing this despite his human appearance as part of his Omni Lord powers.

- Hot-Blooded: Like the other Raging Spirits, though all of them are more level-headed than Ban Enma himself.

In truth, he is Variable Cord himself.
- Affably Evil: He's the head of an illegal Buddyfight club where losers' Buddies are stolen, but he's never rude.
- Actually, I Am Him: Initially deflects suspicion from himself by pretending to just be the guy who hands out invitations to Buddyfight Club. In the dub, he also affects a Deep South accent and mannerisms.
- Also, Variable Cord isn't his buddy, but his true identity.
- Amnesiac Hero: Variable Cord fought Yamigedo alone and then had Dynamis recruit the Omni Lords, but suffered memory loss due to being damaged. Before he went back to the future to heal, he asked Dynamis to re-recruit him as if they'd never met.
- Awesome, but Impractical: Variable Cord's ability can put a large number of cards in its soul but doing so can deplete the player's hand.
- Big Good: To Dynamis. Recruiting the Omni Lords was actually his idea.
- Eyes Always Shut: Suzaku’s eyes are closed most of the time.
- The Four Gods: His three deus monsters resemble the other three gods. He, himself, is named after the Vermillion Bird.
- Get Back to the Future: His objective is to return to Star Dragon World.
- Irony: Never wanted to fight in the first place and wanted to go home. He was the first to fight Yamigedo and asked Dynamis to recruit the Omnilords.
- I Lied: As it turns out, he never had any intention of helping seal Yamigedo and lied to Tasuku about him being tested. He just want to use Jack's power to return to Star Dragon World.
- Jerkass: Well, he does run an illegal Buddyfight club that has "The winner takes the loser's most precious thing and can do whatever they want with it" as a rule. And then, there's him being willing to abandon his role as an Omni Lord to go back to his own world using Jacknife's powers which could have caused the latter to lose his life.
- My God, What Have I Done?: Once he regains his memories.
- Nice Job Breaking It, Hero: Abandoning his post as Omni-Lord to go back home to Star Dragon World caused a doomed timeline where Yamigeddo conquered the world causing Star Dragon World to no longer exist.
- Stealing the Inverse Omni Lords to help Kyoya stop Yamigedo backfired spectacularly, getting all of the heroes Taken for Granite.
- Our Dragons Are Different: Variable Cord has retractable wings instead of arms as well as multiple tails. He's also from the future and has the ability to assume human form.
- Perpetual Smiler: The times he's not smiling could be counted on one hand. He even constantly sounds amused as variable cord.
- Refusal of the Call: He's already saved the world from Yamigedo once, now all he wants is to go home. Ironic since he was the one who put out the call in the first place.
- Secret Test of Character: His offer to save Jack if Tasuku threw the fight turned out to be this... or not.
- Time Travel: Due to being from Dragon World's future. He is trapped in the present due to having been recruited to defeat Yamigedo and uses a severely injured Jack to go back.
- Trapped in Another World: Ever since Yamigedo was sealed, he and the three deus monsters were left unable to return to Star Dragon World and had to remain on Earth. At least, until Star Guardian, Jacknife came.
- He's still trapped due to his future no longer existing. When he finds this out, he agrees to help bring Jack back to the present and help fight Yamigedo again.

He becomes the ninth Omni Lord during a tag match with Kazane after realizing what it means to be a hero.

- Declaration of Protection: Swears to protect Kazane during their tag match against Captain Answer's Superpowered Evil Side and a possessed Kemura. It allows him to become the ninth Omni Lord in Captain Answer's place.
- 11th-Hour Ranger: He gets Captain Answer's Omni Lord emblem after realizing what it means to be a hero.
- Glory Hound: He wants to become an Omni Lord and defeat Yamigedo to gain prestige and glory and be recognized as a hero. To achieve that goal, he isn't above using underhanded methods in order to obtain an Omni Lord emblem.
- Ineffectual Loner: At least partly due to his Glory Hound tendencies.
- Oral Fixation: He can usually be seen with a toothpick in his mouth.
- Took a Level in Badass: Becomes an Omni Lord after realizing that a real hero is defined by protecting others, not seeking glory.

- Walking the Earth: Describes himself as a wanderer.

- Red Oni, Blue Oni: Doble is the red to Meglax's blue while Drum is the blue to Alliot's red.

- Put on a Bus: He is arrested by the Buddy Police after losing to Gao. The Buddy Police appearently got a tip about him from an anonymous source that was totally not from Kyoya.
- The Bus Came Back: Briefly reappears to give testimony against J Genesis. Then he returns near the end to challenge Tasuku, now working for Kyoya instead of against...
- Sadistic Choice: After giving Bal a drug that would erase his memory and turn him into a mindless beast, he gave Gao two options. Either let Zodiac eat Bal, or allow Bal to rampage and hurt his friends. Unfortunately for Gara, he didn't count on The Dragon Force.

- Would Hurt a Child: After capturing Bal, when Bal wouldn't come out of his egg, Doctor Gara tried breaking the egg open with a drill and a chainsaw. Luckily, that egg shell is Made of Iron.
- He then tricks Bal into taking a drug that would wipe his mind and turn him into a feral beast so he could feed Bal to Zodiac.
Star Deity Dragon, Zodiac
An artifical monster created by Gara. Zodiac is also a Dual Card, a monster belonging to two different worlds: Legend World and Star Dragon World in its case. Zodiac is the buddy monster of both Gara and Kakeru Futaboshi. Makes sense since they're the same person.

His buddy is Giant Tanuki and he uses both a Divine Guardians deck and a Searing Executioners deck, both named "Heaven or Hell."
- Bowdlerize: His decks' name is "Heaven or Hell" in the Japanese dub. The English dub changed it to "Nirvana or Gehenna" to keep the theme while still toning the name down.
