The last animated episode of Dragon Ball Heroes shows that along with Goku, Vegeta, Gohan, Piccolo, Hit and Jiren, Yamcha was chosen for Goku's team for the new tournament of power.
Apparently all the androids are together for one team (though not sure if they are from the same universe and timeline than Goku's), but why no other characters (such as Toppo, Dyspo, Tien, Cabba, Caulifla, etc. ) were chosen in his place since they are much more powerful?
Does the Dragon Ball Heroes manga explain why Yamcha and no other characters were chosen for Goku's team in the new tournament of power?
