Description
Boyacky Butsukusa is the Doronbo Gang's primary inventor and mechanical designer, creating their mechas and gadgets. His signature catchphrase "Pochittona" accompanies button presses, becoming notable in Japanese pop culture.

Originally depicted as a 25-year-old with a lecherous personality, his primary ambition is gaining admiration from high school girls; he planned to use the Dokuro Stone's fortune for plastic surgery to achieve this. He frequently makes advances toward gang leader Doronjo but genuinely desires a consensual relationship with someone who reciprocates. His personality includes snarky remarks toward others, though he refrains from targeting fellow gang member Tonzura. He occasionally engages in crossdressing.

As the gang's strategist and location expert, Boyacky designs mechas and controls their combat gadgets. His tendency to overlook critical details often leaves the gang vulnerable, particularly due to easily triggered self-destruct buttons he installs.

After the original gang disbanded, Boyacky married his high school sweetheart Ohana, opened a successful Kokubunji noodle shop, and had a daughter named Happy. Fourteen years later, Doronjo and Tonzura recruited him for the "Royal Revival" OVA race. Initially declining to protect his new life, he rejoined to rescue his trapped comrades, designing an advanced evolving mecha for the conflict.

The 2008 series reboot reimagined his backstory: aspiring to be a noodle chef in Koriyama, he failed despite receiving a special rolling pin from Ohana. Career limitations led him to crime and the Doronbo Gang, though he maintained emotional ties to Ohana. His obsession with high school girls intensified, causing a moral dilemma when he briefly gained their admiration during a mission. He wielded the versatile "Tokkae gun" in direct confrontations. The 2008 movie revealed his deeper wish to become a high school girl, manipulated by villain Pa-Zulu into constructing a dangerous hammer mecha. Post-series, he planned to reconcile with Ohana but ultimately chose to continue with the gang.

Later, Boyacky's Las Vegas gambling resulted in a massive financial windfall, funding the Doronbo Gang's short-lived "social reform" initiatives in "Heisei Time Bokan." Deceased by the events of "Yatterman Night," his descendant Voltkatze inherited his alias and role in the reformed Doronbo Gang's rebellion.
