Baki Hanma Season 2

In Hanma Baki’s first season, the fighter Baki — the strongest high schooler in the land — trained in a prison against fellow inmates, defeating a giant praying mantis and formidable opponents like Biscuit “Mr. Unchained” Oliva and Jun “Mr. Second” Guevaru. Now, Baki is back and gearing up to battle Pickle, a perfectly preserved prehistoric man so powerful, he once preyed on dinosaurs. If Baki can take down Pickle, his final matchup will be with his all-powerful father, Yujiro Hanma.
