Phoenix (Marvel: Ultimate Alliance)

Jean Grey is a playable character in Marvel: Ultimate Alliance 2 and is a member of the X-Men. In Mephisto's realm, if the player chooses to save Nightcrawler instead of Jean, she will return as the Dark Phoenix. Which starts the events of the Dark Phoenix Saga. For some reason, Jean Grey somehow return to the good side, X-Men remain active due to Nightcrawler being active, indicating retcon Jean and Nightcrawler's fates by player's choice in the first game. However it is likely that Nightcrawler is the 'canon' as in the post game it is stated that Jean returned as Dark Phoenix, but somehow regained her senses afterward.

As of Marvel: Ultimate Alliance 3, she simply listed as Phoenix, as well as being a boss character under the alias Dark Phoenix. Jean is the titular main character of the third game's second DLC's storyline.
