Baki the Grappler (2001)

Baki Hanma is an exceptionally strong young man. He spends every waking moment training and fighting so that he may someday surpass the fighting abilities of the strongest being on Earth--his father Yujiro, a cruel man who lives only to fight and hurt people. On his path to becoming the strongest, Baki fights and trains with masters of various fighting styles, always looking for new ways to increase his own strength and fighting technique.
