Marvel Rivals crosses over characters from multiple universes to create an exciting match-up. This is because if the heroes and villains were comic-accurate their powers would be on drastically different levels. NetEase would be in a difficult spot if half the Duelist characters couldn’t put a dent in most of the Vanguards, or if personal weaknesses could be triggered. Thankfully, Marvel has allowed for creative freedom and doesn’t restrict the game to just Earth-616 and other character origin worlds.
