Donatello, a once-elite warrior in the Top Ranker unit alongside Kaburagi, honed his skills against Gadoll threats. Seven years earlier, teammate Mikey defied warnings about the banned limiter release protocol, activating it despite the risks of bodily destruction and corporate retribution. His subsequent execution for insubordination collapsed their team and banished Donatello to the Bug Correctional Facility, where he seized command of imprisoned dissidents labeled "bugs."

As the facility’s unruly patriarch, he ruled over inmates like Turkey, Jill, and Sarkozy, his volatile blend of aggression, combat obsession, and unyielding loyalty mirroring his hatred for the corporate order that jailed him. This bitterness fueled his alliance with Kaburagi’s rebellion—less for idealism than vengeance and a craving to dismantle the system through calculated havoc, inadvertently propelling its downfall.

His physique broadcasts his martial legacy: a towering human form with violet-hued skin, sharp green eyes, and cropped white hair shorn on the left, mirrored by a cyborg body armored in purple plating, a yellow head fin, and a left-arm pink energy cannon. While his post-revolution fate remains unrecorded, the fractures he carved into the hierarchy endured, reshaping the world’s power dynamics.
