A prominent Marvel Rivals leaker reveals that the villain Ultron may be coming to the hero shooter in Season 1 as a Strategist, going on to detail the character's ability kit. As of this writing, there are 33 characters within the roster of Marvel Rivals. All of these heroes and villains belong to one of three roles: Vanguard, Duelist, or Strategist. Vanguards are typically capable of blocking or taking a lot of damage, while Duelists dish out damage most efficiently. Strategists fill a support role within the game, providing heals and buffs while also mixing in attacks when they can.
