Description
Boyacky Butsukusa, also known as Boyakki, is the Doronbo Gang's technology expert and mecha designer. Tall and slender, he has prominent buck teeth, a large nose, and a mustache, typically wearing a green uniform that leaves his midsection exposed.

His personality combines intelligence with lecherous tendencies, marked by an obsession with gaining admiration from high school girls. He frequently makes advances toward the gang's leader, Doronjo, while desiring genuine mutual relationships. Despite his technical skills, his mecha designs often overlook critical details, like easily triggered self-destruct buttons, contributing to the gang's repeated failures. His catchphrase, "Pochittona," uttered when activating his inventions, became a recognizable element in Japanese pop culture.

Boyacky initially aspired to be a noodle chef in Koriyama, supported by his girlfriend Ohana who gifted him a special rolling pin. Culinary failures confined him to dishwashing, driving him toward crime and eventual membership in the Doronbo Gang. He severed ties with Ohana out of shame. Designing giant mechas for the gang's global missions to collect Skull Stone fragments for their boss Dokurobei, Boyacky's efforts consistently ended in defeat by the Yatterman duo, followed by punishment from Dokurobei.

After the gang disbands, Boyacky reconciles with Ohana, marries her, and establishes a successful noodle shop in Kokubunji; they reportedly have a daughter named Happy. Fourteen years later, Doronjo and Tonzura seek his help for a race in *Time Bokan: Royal Revival*. Initially reluctant due to his peaceful life, Boyacky rejoins them when they face imminent defeat, aiding their victory. He later designs a transformative mecha capable of evolving through life stages, including a high school girl form reflecting his fixation.

In subsequent reunions like the 2008 series, Boyacky resumes his role with the Doronbo Gang, continuing their pursuit of Skull Stone pieces. His obsession with high school girls intensifies, causing internal conflict when he briefly gains their admiration. During a film arc, he is manipulated into building a world-threatening mecha by the false promise of becoming a "minister of high school girls," revealing his deeper wish to transform into one.

Following another disbandment, Boyacky intends to return to Ohana but ultimately rejoins Doronjo and Tonzura. His activities later funded the gang's short-lived "social reform" initiatives through massive gambling winnings in Las Vegas.

In the distant future of *Yatterman Night*, Boyacky has passed away; his descendants are exiled from the Yatter Kingdom. His descendant, Voltkatze, adopts the Boyacky alias and joins a rebellion against the oppressive regime.
