Several characters mention Mundus, the main antagonist of Devil May Cry, before or after fighting one of the characters from that series. Before the battle with Trish, Ghost Rider will say "I eat demons like Mundus for breakfast.". Phoenix (Jean Grey), after defeating Vergil, will say "Perhaps if I'm not too busy, I'll take care of Mundus, too." Dormammu also says to Dante that he should stick to fighting Mundus, implying not only that Dante is not strong enough to defeat him, but that Dormammu is more powerful than Mundus.
