You gonna make me fight some Saibamen again? Sorry to disappoint you, but it's not gonna work this time!
—Yamcha, when fighting Nappa
Yamcha is the known punching bag of the Dragon Ball universe, but known as a powerful fighter in the UnAnything universe. It all started when Yamcha was out partying, minding his own buisness, before Vegeta betrayed and trapped him in the hyperbolic time chamber for years and years on end. He searched for the Dragon Balls before this happened, and wished for immortality. So many years after this incident, he decided to get a P rank in every Pizza Tower level to escape the hyperbolic time chamber.
After escaping, he realized that he wasn't in the Dragon Ball universe as he was in Ohio. Yamcha would then start training to become stronger, but he finally realized it: 1. Bulma didn't love him, and 2. He is on UnAnything. He kept on training to become stronger but then Nappa arrived with his Saibamen and kicked his ass. In his universe, he would have instantly killed Nappa + the Saibamen, but these are strange lands.
The new Akatsuki saga[]
Yamcha had his run-ins with Pain Incorporated while working for good. He soloed most of the members as he didn't have time for any of this shit, because he needed to get high and become a baseball player again, so he did so and got a perfect streak. But a new big bad slowly was being revived with the help of Pain Inc. and Shao Kahn, so he and his allies decided to take them on. During one of the fights, he was playing baseball when the evil of the Akatsuki and the furries showed up and tried to ruin his baseball game. This is where he learned Slugger Style or his Baseball Form, and proceeded to wipe the floor with them after trying to protect OHIO from the new evil. He was called by a certain Reimu Hakurei to get his ass to Gensokyo or else she'd "...beat [his] ass so hard [he] will feel like Vegeta when Android 18 kicked him.". He decides to go to Gensokyo to help her fight youkai, but Flandre Scarlet sadly she made him Asplode, though he got back up and beat her with a belt.

Yamstream Sam[]
Yamcha got high in the desert and decided to buy a sword and become "the Jetstream Sam of UnAnything", interrupting cringe and destroying NSFW characters, but still: he required bitches. He remembered that Vidro existed, so he married her. Well, that was until Shao Kahn hired assassins Death the Kid, El Hermano, Imperial Japan, and Chill Bill to jump him, and guess what? He was kicking his ass to a bloody pulp, but he was finally breaking to become his final form (he never learned drip form yet)

Ultra Instinct Yamcha[]
Yamcha went Ultra Instinct, and was ready to beat their asses so they came one by one, and he went swinging: He wolffang fisted Death the Kid, followed by a Kahmehameha (that he learned in the hyperbolic time chamber) turning "the death kid" into "the dead kid". He calls in Gohan Blanco to beat El Hermano's ass. He used his sword that he had in his Yamstream Sam Mode to sword fight Japan. He kills her off by impaling her with his sword, before cutting her down. Chill Bill tries to freeze him but he dodges, and traps him with the Skylanders Trap Team trap, planning on using it later. He leaves the desert and realizes the power to make a new Z Fighters.
The Z Fighters 2[]
He decided to recruit Goku, Marisa Kirisame, Vegeta, Cooler, Pepsiman, Sub-Zero, Tien Shinhan, Plant Man and Phobos as the heroes of this planet to defend the UnUniverse from evil. He's also feeling like Adopting Hana Kyuo into his family.
His Involvement in Round Star[]
After hearing about Hana's death Yamcha fucking went pure anger mode and unlocked kaioken in the process he is now going to Round Star with Tien to avenge her death so he trained for several months before going to roundstar but babidi possessed him turning him into Majin Yamcha but his hatred of the person who killed Hana was enough for the mind control to fail but for the m symbol to remain on his forehead. Yamcha will Avenge Hana's death even if he dies too
Majin Yamcha[]
Majin Yamcha is Yamcha during the Round Star Arc he is a version of Yamcha that has been taken over by Babidi's mind control in order to gain enough power to summon Majin Buu But Yamcha is self aware of this form and is allowing the evil in his mind to be focused on one thing and one thing only and that was to kill Judge Holden to Avenge Hana's death. Mrs. Toonami is scared of what Yamcha has become but he made it clear that he will deal with Babidi after he kills Judge Holden and mutilate his body beyond Recognition. He is currently traveling to Round Star with Tien
