Dragon Ball Super
Universe 6 Saga
Main article: Universe 6 Saga
The Omni-King watches the Universe 6 and Universe 7 tournament from a distance away of the Nameless Planet. After the tournament concludes, Champa is angry that his team lost and prepares to destroy them. However, the Omni-King and his attendants arrive on the Nameless Planet in the ring, which prevents him from doing so, as he along with Beerus are completely mortified and shocked by the Omni-King's presence. He states that his reason for visiting was because he believed Beerus and Champa were shirking their duties as Gods of Destruction. He asked how Beerus and Champa were doing in their jobs, and Whis tells him that Beerus focuses more on sleeping and consuming food more than doing his job, and Vados notes that Champa completely obsesses over food and all of the sweets that result in him being fat, and whatever food Vados serves Champa, he says it is awful.
The Omni-King then considers hiring new Gods of Destruction, while both Champa and Beerus are completely scared, but then the king says it was just a joke, much to the relief of Beerus and Champa. However the Omni-King made no attempt to stop the tournament, as he enjoyed it himself. Because he enjoyed it, the Omni-King proposes a martial arts tournament between all twelve universes in the future. Goku is excited hearing this and attempts to speak with the Omni-King upfront.
