Since the original six actors emblazoned their signatures on the screen during the credits of Avengers: Endgame, fans of Earth's Mightiest Heroes have wanted them to come back. The third episode of What If…? Season 2 gives fans the original Avengers back for a Christmas adventure, mostly focused on Happy Hogan. While it's not exactly what Marvel Cinematic Universe fans may have wanted, it was the best way to revisit this history-making team. Of course, it's not quite the original Avengers team, since a major conceit of the What If…? series is each episode exists in an alternate timeline.
