5. One of the most prevalent characters in the game is this "Merc with a Mouth", who has both a daily event and one where he goes up against the entire Marvel Universe (well, most of the ones in the game, anyway). Who is this character?
From Quiz Marvel Puzzle Quest
Answer:
Deadpool
Deadpool first appeared in "The New Mutants" #98 (1991). While he has super-human healing ability, he's not quite sane and tends to break the fourth wall. In fact, he knows that "Marvel: Puzzle Quest" is a game and "talks" directly to the player.
In "Marvel: Puzzle Quest", the cover for this 3-star character was originally the Hastings variant of "Deadpool" #11 (2013), which portrayed Deadpool as a character in a video game. However, due to a rights issue, this cover was changed to the Deadpool variant of "Uncanny Avengers" #1 (2012).
