Baki Hanma is the son of Yujiro Hanma the world's strongest creature. Baki pushes himself to become to a better fighter, so that he can one day defeat his father.
A skilled fighter training to beat his father Yujiro Hanma. His mother, Emi Akezawa, helps him along the way by hiring trainers by providing him throughout his life with the best Martial art teachers, personal gym trainers, and sport equipment that money can buy.
Baki at one point realizes that non of what his mother is supplying him is enough, and destroys his home gym. this is due the fact that he lost a fight against 100 guys in an alley, thinking that his father would have done a better job. he later goes on a journey to find better ways to advance his fighting skill after getting knocked out when challenging the world middle-weight champion in kick-boxing.
Baki goes to the mountains where he meets an old friend who used to baby-sit him as a young kid. his primary objective was to fight and win against the Yasha ape, like his father, in an urban legend. After defeating the ape and returning home, it is noticed by his mother and the boxing champion(Yuri Chakosky) that he seems bulkier, and bigger. when he returns to Yuri's gym he explains to him that boxing sports are imperfect martial arts, and surprises them by slicing a punching bag with a wave of one hand. Baki also sees Yuri alot slower than he was before.
Kaoru Hanayama is a mob leader, and member of the Yakuza clan that crushes Yuri's hand before his title fight. Baki, after finding out, barges into Hanyama's office dragging the henchmen from outside, demanding a fight. eventually, the fight leads to the mall where Baki wins.
Endorphins Secretion: Baki has the ability to release more endorphins in his body by twisting his right ear, he first felt that experience when he threw himself of a cliff.
Demon Back: a person with the Hanma family blood flowing through his veins, earns at some point, a demon face figure shaped on his back from great fighting experiences. when ever he flexes his latissimus dorsi muscle, he reaches combat capabilities unattainable to him before.
Shadow Boxing Figuration: Shadow boxing is a basic way to train in boxing by punching and dodging imaginary opponents, but when baki does it, he actually forms a real opponent that can be seen by other people, but he is the only one that can touch/be touched by him, this is proven after observing the scars, bruises, and blood on his body after a shadow boxing session.
