Fabris rules as king of the Light Tribe, commanding their forces in the enduring war against the Shadow Tribe. He is the father of Maria and grandfather of Mew, showing protective concern for his family lineage despite his aggressive actions towards others. Physically, he sports short brown hair that greys in later years, brown eyes, and fair skin. He suffers the severing of his right arm during a confrontation with Astral, who intervenes to stop Fabris from assaulting Sharon. In his future appearance, he wears a distinctive red crown.

An exceptionally skilled and experienced knight, Fabris surpasses the combat abilities of both Kaiser and Sharon from the Shadow Tribe. His obsession with Sharon ignites after witnessing her battle prowess, driving him to make multiple attempts to violate her. In the anime, he actively attempts to rape her on the battlefield after defeating her, halted solely by Astral's intervention. Within the original game, he employs an aphrodisiac-coated dagger to incapacitate Sharon, successfully wounding her with it.

Fabris initiates large-scale assaults against the Shadow Tribe, including attacks that result in the capture of Light Tribe prisoners like his own daughter, Maria. Following Astral's disappearance and return two decades later with amnesia, Fabris manipulates him by exploiting this memory loss. He identifies Astral as the legendary swordsman Pollux, using him to breach the Shadow Tribe's defenses in pursuit of a decisive victory. After this time skip, Fabris remains active as the Light Tribe ruler, ordering Astral's execution upon his return – a plan that fails. His role then diminishes significantly during later events focused on uniting the tribes, with no further character development or major actions documented.
