Dragon Ball Super S03E01 - The 6th Universe's God of Destruction — His Name's Champa

Goku and Vegeta continue their rigorous training before being chased by an enraged Beerus, whose awakening was caused by Champa and Vados abruptly arrive on Beerus' planet. After a small skirmish between Beerus and Champa, everyone settles down to eat some food with Champa formally introduced as Beerus' twin brother and Vados as Whis' older sister. An argument erupts concerning which universe's food is superior, with Whis explaining to Goku and Vegeta there are eleven universes besides their reality: The Seventh Universe. Whis adds that both the Seventh and Sixth Universes complement each other as their designated numbers add to thirteen. After Vados discovers that Universe Six's Earth has been destroyed through warfare, Champa proposes a tournament with Beerus with the winner allowed to swap Earths. Beerus protests until Champa reveals the feat is possible with the Super Dragon Balls, which the Namekian Dragon Balls were trimmed from, possessing six of them. Goku informs Beerus and Champa that Bulma is capable of locating the final Super Dragon Ball necessary to perform the wish. With tensions mounting, Beerus accepts Champa's proposal.
