The mother and ruler of the Melzard Tribe.
  • Big Bad: The ruler of the Melzard Tribe and the one behind their assault on the surface.

First Son Dinosaur Warrior Raija

Portrayed by: Akira Ooka
The first son and prehistoric war-leader of the Melzard Tribe.
  • Came Back Strong: He's a whole lot stronger after coming back from the dead, to the point where he and Dezzle easily overwhelm the B-Fighters in their first outing with their new forms.
  • The Dragon: The first born son of Mother and the commander of the Melzard Tribe's invasion.
  • The Heavy: Since Mother herself is immobile, Raija is the one who leads the attacks against the surface, alternating this role with his brother Dezzle.

  • Red Is Violent: Is mostly red, and an evil warlord who commands an army of vicious monsters.

The fish-like second son of the Melzard Tribe, who competes for power with his older brother Raija.
  • All-Encompassing Mantle: He wears a wide black cape in his revived form.
  • The Brute: He's much more of an eager and brute force fighter than his brother.
  • Came Back Strong: Like Raija, he comes back much stronger after returning from the dead.

  • Off with His Head!: Inverted. His head is the only part of his body that remains after he's obliterated by the B-Fighters for the first time.

  • Designated Girl Fight: Whenever she takes to the battlefield she'll most often find herself battling the lone female of the B-Fighters, Tentou. In the Final Battle, she faces Tentou one last time and gets slain by her, making her the only major villain in the series whose death Kabuto didn't at least play a part in.
  • Master Swordsman: As her title would suggest she's very formidable with the rapier.
  • Undying Loyalty: To Raija, to the point where even after he's slain for the first time, she takes his body back to Melzardos and spends the next few episodes watching over it.

Rock Shell Chamberlain Dord

Portrayed by: Hiroshi Masuoka
The seashell-like younger brother and assistant of Dezzle.
  • Evil Genius: Don't let his demeanor fool you, he can be quite a cunning and crafty planner.
  • Laughably Evil: Of the Melzard generals, he's the only who's more goofy than serious and tends to be played for comedy most of the time.
  • Yes-Man: To Dezzle, repeating whatever he says.
A team of Evil Counterparts created by Mother Melzard from Insect Medals to be Melzard's equivalent to the B-Fighters. They consist of Descorpion, Mukadelinger, Killmantis and Beezack.

  • The Psycho Rangers: Created from the Insect Medals, the same power source the New B-Fighters use, and intended specifically to counter the B-Fighters.
  • Quirky Miniboss Squad: They're a team of distinct villains tougher than your average Melzard Monster and the Monster of the Week fights gradually get replaced with encounters with them starting from their debut, although you can replace "quirky" with "dangerous" moreso.


The leader of the team. A red warrior based on a scorpion
  • The Dragon: Descorpion becomes Mother's favored enforcer soon after his creation, and rivals this role with both Raija and Dezzle.
  • Harpoon Gun: Has one mounted on his wrist.
  • Noble Demon: Has shades of this during his last few appearances. He prefers direct combat with the B-Fighters and sees his destruction at their hands as a noble outcome.

  • Scary Scorpions: His motif.


A black warrior based on a centipede.
  • Blade on a Stick: Uses a spear with two edges.

A green warrior based on a mantis.


A warrior resembling a bee.
