Super Dragon Ball Heroes S05E01 - A Plan In Motion - The Mightiest Warriors From Across Space-Time Gather!

In the Time Nest, Chronoa (the current Supreme Kai of Time) is confronted by the mysterious alien woman, who is revealed to be Aios, a former Supreme Kai of Time. On Earth, Goku is visited by a strange being who invites him to participate in the "Super Space-Time Tournament," a grand martial arts tournament involving many other timelines. Goku accepts the invitation and is transported to another realm, where he discovers that Gohan, Piccolo, Vegeta, Hit, Jiren, and Yamcha have also been invited to compete in the tournament as a team. They are introduced to the other teams, and it's revealed that there are twelve teams in total, each with seven members. The tournament announcer explains that the first round of the tournament will last 24 minutes and will be a battle among all twelve teams, where the objective is to either capture one of three Time Fairies, or to defeat all the members of the other teams. As the tournament begins, all seven members of the main timeline's team are transported to different locations on an unknown world. Goku is confronted by Xeno Goku, who reveals that Aios is hosting the tournament and that the Time Patrol have sent a team to participate because they have business with her. The two Gokus are attacked by a group of fighters from another team, and prepare to deal with them. As many other battles begin across the tournament grounds with 14 minutes remaining in the first round, Aios observes the proceedings from afar.
