Hamma Jamma is a Hammer Bro. who fights in the Glitz Pit in Paper Mario: The Thousand-Year Door. He fights with Bamma and Flare. It is possible that Bamma and Flare are his brothers.

Hamma often talks about his grandfather; coincidentally, Mario may have actually met this highly talked of grandfather, as Hamma once said his grandpa's turf was "World 7-1". He also constantly tells Mario about his other family members (whom he apparently left), such as his father, the only known Business Bro.

He and his teammates are ranked 3rd in the Glitz Pit when Mario starts his Fighter career.
