Bills and Whis are having tea and rice with King Kai when suddenly Dormammu enters Other World and tries to take it over for himself. Bills and Whis get mad at Dormammu's interruption and attack him. Can Dormammu defeat them both?
Dormammu is of course outside the Dark Dimension and so doesn't have in realm power. Dormammu had no idea of Bills and Whis's presence before entering Other World so he has no prep on them.
Battle won by BFR or death.
