Yamcha

Summary
Yamcha (ヤムチャ, Yamucha) is a supporting character in Dragon Ball Super. He is a former boyfriend of Bulma and the lifelong best friend of Puar.

Resurrection ‘F’ Arc
Some time after the battle with Majin Buu, Yamcha and Puar head towards Bulma's birthday, which is being held on a cruise ship, where they encounter Krillin, Android 18, and their daughter, Marron. They are also flying to get there, as it was taking too long driving in a car. Yamcha and Puar later encounter Tien Shinhan and Chiaotzu on the ship. When Beerus arrives on the ship, Yamcha is one of the first to introduce himself to Lord Beerus. He exaggerates his power, proclaiming himself as the strongest one on the ship. He roughly slaps him on the back, which worries Vegeta that it might upset him, but Beerus just shrugs it off.

Yamcha joins the crowd of people when Beerus eats the octopus balls served to him by Krillin, with one containing wasabi. They chant him on, encouraging Beerus to take a bite. Later, Yamcha joins several others as they board Bulma's space pod to get a better view of Goku and Beerus' fight. In the end, Beerus beats Goku, but he doesn't destroy the Earth because he falls asleep in the process.

Sixth Universe/Champa Arc
Yamcha is traveling with Goku and the rest of the gang to the Nameless Planet where the Universe 6 and 7 Gods of Destruction Selection Martial Arts Competition is being held and they're being taken there by Whis in his cube. After two hours and forty-five minutes of traveling, they arrive on the Nameless Planet. Yamcha is a bystander and watches the tournament from the stands. He watches the first match between Goku and Universe 6's, Botamo. He is later shocked along with everyone else when Goku is defeated by Frost. During Vegeta's match with Cabba, Yamcha points out similarities between Cabba and a young Goku he fought when they first meet long ago. As Vegeta begins toying with Cabba, he shows some doubt that Vegeta has rid himself of all of his sinister qualities, but dismisses them once he realizes that Vegeta simply wanted to push the weaker saiyan to increase his power.

He later comes to the celebratory party at Bulma's, and spends most of his time talking to Tien. He accidentally reveals to Goku that Monaka was passed out and not actually the strongest in the universe.
