Fistleo

Fistleo the Predatoroid is the guardian of the burning city (that he set on fire), Area G.

Appearance
Fistleo is a lion-style Pseudoroid with a bulky scarlet body evoking the look of a muscular fighter. He also has an orange mane that can ignite itself, green lights on his upper body and clawed hands and feet.

He has a fragment of Biometal Model F inside his head, granting him flame powers and allowing him to produce fire with his fists. In battle, he combines this power with his own blend of kenpō named "Reioh-ken" ("Reiouken" in the manga).

A Pseudoroid with a fierce personality, Fistleo is only interested in honing his skills and increasing his strength. He will do anything to gain power, which is the reason he joined Serpent's ranks. He despises weaklings.

History
Promised the power of a god by Serpent, Fistleo accepted the proposition to be transformed into a Pseudoroid. He received half the data of Biometal Model F, with Flammole receiving the other half. He leads a Maverick assault on Area G, kidnapping people and setting buildings ablaze even though this interferes with his training. He confronts the Mega Man Model ZX expecting a great warrior, but is disappointed to find the Chosen One is still a child. Fistleo is defeated and his half of Model F is taken, but he is later revived for the final battle in Slither Inc.'s head office. Though he loses a second time, he claims that his spirit will continue to fight and believes that by becoming one with Model W, he is finally obtaining the power he sought. In Aile's storyline he has a similar role, although he also implies that anyone spared from a Maverick attack were spared deliberately for the purposes of the Game of Destiny.
