In the world structure of Dragon Ball Super, the twin brothers of the virus have twelve universes. The virus is the destroyer of the seventh universe, and Champa is the destroyer of the sixth universe. The two universes are very similar, and the corresponding characters and planets are similar.

Viruses and Champa are often at odds, and no one will obey. In their respective cosmic food competitions, Champa's cosmic food was completely defeated, so they later held a God of Destruction competition and chose their own cosmic strongman.
