Badō Nails, a chain-smoking freelance information broker and photographer, sports red hair and an eyepatch concealing a scar from Richter Berthein’s assault seven years ago—an attack that claimed his brother Dave’s life. This tragedy drove him to adopt smoking as a coping mechanism and pursue his brother’s investigative career, fueled by a vendetta against the underground organization behind the incident. His temperament fluctuates with nicotine levels: calm when supplied, lethally volatile when deprived. Though reckless, he clings to pragmatic survival instincts, balancing cowardice with unexpected combat prowess when cornered.

Partnering with Heine Rammsteiner on missions for Grandma Liza, their dysfunctional yet loyal dynamic earns them the alias “White Hair and Eyepatch.” Badō favors Ingram MAC-10s but switches to Glocks or M1911A1s when necessary. His alliances include a teasing friendship with information broker Mimi, a distant rapport with retired assassin Mihai Mihaeroff (“old man”), and an obsession with confronting Berthein, whose hypnotized forces hunt him relentlessly.

Investigations often entangle him with “Lost Children”—genetic experiments—sparking clashes with criminal factions that require Heine’s intervention. His name, a nod to Nine Inch Nails, blends Japanese pronunciation (“bah-doh”) and French origins (“bah-doo”), reflecting the series’ European-inspired dystopia.
