|Bisuketto Oriba (ビスケット オリバ)|
|Debut (Anime):||Public Enemy Zero|
Biscuit Oliva is a gigantic man with such musculature as to look overweight when wearing a suit. His muscles are dense enough to repel close range shotgun blasts and he boasts that the only training he needs is to keep his muscles in check all day. He was capable of easily breaking the spine of a Kaioh known for his toughness. It's worth noting that he is one of the few people that Yujiro has respect for.
HistoryOliva is first encountered by Baki in prison, as Baki's purpose at the prison was to fight him. Oliva shows off his lavish lifestyle that he has and has Baki thrown back in with the general population. Not long after, he defeats Che Guevara in a difficult fight, making Baki the next challenger. He tries to propose turning it into a sporting event, but Baki is impatient and wants the fight then. For the actual fight, he brings out his wife he's been ranting about and she turns out to be morbidly obese. Baki manages to defeat him in a tough fight and is released, as Oliva wants. He is clearly able to leave the prison at any time he wants and literally seems to be in charge of the place.
He takes part in the Kaioh tournament, at first just because he's watching after the now harmless Dorian who is obligated to participate. You Kaioh is angry that his opponent didn't fight back and challenges Oliva who easily crushes him. He then fights the Iaijutsu user Ron Shun Bun and wins with massive headbutts despite taking a lot of damage.
- Biscuit Oliva's appearance and name are based on the former Mr. Universe and three-time Mr. Olympia, Sergio Oliva.
