Team Universe 7 is a team presented by Beerus with the strongest warriors in Universe 7 in order to participate in the Universe 6 and 7 Gods of Destruction Selection Martial Arts Competition. The team consists of Goku, Vegeta, Piccolo, Majin Buu, and Monaka (introduced as Beerus' strongest opponent) with Beerus and Whis as the team's supervisors.
When Beerus and Champa organized a Universe 6 vs. Universe 7 5-on-5 martial arts tournament, this team was organized to represent Universe 7. Goku and Vegeta are the team's first members, and Beerus instructs them to recruit two of their friends to participate, leaving the last spot for a member for Beerus to choose. Goku and Vegeta recruit Piccolo into the team. In the anime, Gohan, having been training with Piccolo, requests to be apart of the team, but then says he cannot participate due to having a conference on the same day. In the manga, Vegeta requests that Gohan be apart of the team, but Goku shoots him down, saying he is too busy with his scholarly duties.
Goku then suggests that Majin Buu be apart of the team, but Vegeta asks him why, reminding him that he lost a lot of power after his Fission, however Goku says that Majin Buu can still become incredibly strong if he fights seriously. The last member of the team is introduced to be Monaka, as Beerus says that while Goku was his second strongest opponent, Monaka was his first, dubbing Monaka the strongest fighter in the universe.
On the day of the tournament, Majin Buu is unable to participate due to failing the written test before the matches, leaving Team Universe 7 down to 4 members. The first match was Goku vs. Botamo, which Goku won. The second match was Goku vs. Frost, which Frost won. The third match was Piccolo vs. Frost, which Frost won. However, it is revealed that Frost was cheating, and Goku was allowed back in to fight after Vegeta, and Vegeta says Piccolo will forfeit. Vegeta later defeats three opponents in a row: Frost, Auta Magetta, and Cabba. Vegeta is then defeated by Hit, and Goku fights him, but after an intense match, Goku deliberately allows himself to lose. Monaka is left to fight Hit, but due to Goku's nature, Hit deliberately allowed himself to lose, and Team Universe 7 ended up winning the tournament.
All members of Team Universe 7 grouped together again for Bulma's Universe 7 victory party.
