Boyacky Butsukusa, also known as Boyakki, serves as the Doronbo Gang’s chief mechanical engineer and cunning strategist. Notorious for his lecherous inclinations, he nurses an insatiable craving for admiration from high school girls—a fixation intensified in modern retellings. His lanky silhouette sports a wiry mustache, protruding buck teeth, and a green uniform that exposes his midsection.

Though initially drawn to culinary ambitions, aspiring to master noodle craftsmanship with a cherished rolling pin gifted by his childhood love, Ohana, repeated kitchen disasters pushed him toward crime. His technical brilliance fuels the gang’s signature mecha designs, though his creations frequently conceal critical weaknesses, such as self-destruct systems prone to accidental activation. He wields the multipurpose Tokkae gun, adaptable as a laser, flamethrower, or adhesive sprayer.

His chronicle weaves through multiple eras: recurring defeats by heroic rivals invite brutal reprisals from the gang’s leader, yet brief respites see him retire to marry Ohana and operate a noodle shop. This tranquility shatters in *Time Bokan: Royal Revival*, where he resurfaces to thwart rival villains and later clashes with icons like Gatchaman and Casshan.

The 2008 reboot amplifies his fixation on schoolgirls, trapping him in a scheme to build a cataclysmic mecha under false pretenses. Post-crisis, he contemplates reuniting with Ohana but ultimately gravitates back to the gang’s chaotic fold. Expanded universes reveal post-gang exploits, including a Las Vegas gambling spire funding short-lived "reform" initiatives. His legacy echoes through *Yatterman Night*, where descendant Voltkatze inherits his defiance against tyranny.

A blend of intellectual vanity and slapstick bumbling, Boyacky oscillates between delusions of grandeur and desperate bids for validation. Beneath his blunders lies steadfast loyalty, repeatedly drawing him back to the gang’s madcap schemes despite fleeting chances at redemption.
