The manga series Baki the Grappler and its sequels feature a large cast of fictional characters created by Keisuke Itagaki. It follows teenager Baki Hanma as he trains and tests his fighting skills against a variety of different opponents in deadly, no rules hand-to-hand combat. His goal is to eventually defeat his ruthless father Yujiro Hanma, who is touted as "the strongest creature on earth" and whom he despises. Many of the characters are fighters trained in various forms of martial arts with skills that reach superhuman levels.

:Baki has been training in martial arts since the age of three, and has trained under various teachers and coaches throughout his life. At the age of thirteen, he decided to take his training into his own hands and left the coaches to perform more intense training in the footsteps of his father, Yujiro Hanma. He later meets with his father and becomes disillusioned as to his father's true character, and afterwards, aims to defeat and kill him. Baki first fought in the no-rules arena run by Mitsunari Tokugawa at fifteen, and went on to become its champion without losing once. Including techniques from many different martial arts, he does not adhere to any specific style. Fighting once a month, Baki thoroughly studies his opponent leading up to their match. He eventually develops the ogre/demon face on his back when fighting his brother, Jack, but manages to suppress it. Unlike Yujiro, Baki chooses to control his killing intent and fight his battles fair and honorably no matter what the outcome. Baki has encounters with all the escaped convicts in the second manga series. He is then faced with a new foe from the prehistoric era, Pickle the caveman, after Retsu and Katsumi are defeated by him. The outcome of the match between Baki and Pickle could be considered to have gone either way: Pickle was the one who was left standing after the fight with Baki, but inadvertently used a "weapon", in the form of a martial arts technique, to beat him. As stated by the onlookers a "weapon" is a tool used by the "weak" against the "strong", which would make Baki the true winner of the fight for having cornered Pickle. Subsequently, Baki's wish to have dinner with his father like a normal family is granted. Yujiro Hanma goes to his house and eats the dinner prepared by his son, dispensing never before seen knowledge with class and proper mannerisms. As thanks for preparing the meal, Yujiro invites Baki to a dinner "in his own style" at Tokyo's best restaurant. At one point during the dinner Baki asks Yujiro why he had to kill his mother; Yujiro refuses to explain his motives "to a resentful brat" and Baki grows confrontational. This triggers their final conflict, and the final part of the manga. The gruesome fight that ensues leaves Baki a broken mess despite using remarkable techniques that earn him the praise of his father. However, Yujiro recognizes Baki's unique fighting spirit and acknowledges that he can no longer be so selfish as to call himself the strongest creature on Earth. To thank Baki he starts using imaginary cooking to prepare Miso soup. Baki plays along but says the soup is a little salty, which angers Yujiro, but when he "tastes" it himself he discovers that the miso was, in fact, salty. Baki claims the moral victory due to being able to get his father involved in his own fantasy. The conflict ends in a tie, both fighters recognizing each other's greatness. In the fourth manga, he is still seen participating in arena fights and engaging in regular intensive training, but has become bored with his day-to-day life.

Pickle has not been a contender in any CBUB matches.
