Bitool appears exclusively in "Code Geass: Lelouch of the Re;surrection" as the warden of a major prison facility in the Kingdom of Zilkhstan, having previously operated as a bandit.

He possesses an exceptionally tall, hunched frame. His distinctive features include magenta hair reaching his chest, black eyes, and red facial markings on both cheeks, contributing to an overall feline-inspired design.

Bitool rules with ruthless sadism and corruption. He openly relishes torturing prisoners and directs graphic threats toward female captives like Kallen, referencing past violence against women. His primary drive is financial gain, displaying consistent greed that supersedes other concerns. Despite this, he exhibits loyalty and obedience to superiors, especially Princess Shamna. He shows brief grief when Kallen kills his subordinates in battle, but quickly shifts focus to demanding higher payment.

Significant physical agility allows him to perform high jumps, and his strength enables him to overpower skilled fighters such as Kallen. He is also a proficient Knightmare Frame pilot.

During the film's events, Bitool actively opposes Lelouch's allies. He captures Kallen after subduing her during the prison assault. Later, he participates in the final battle at Zilkhstan's capital, witnessing his subordinates' deaths. He does not appear in other Code Geass media like television seasons, OVAs, or spin-off materials.
