Here we see some "what if" goodness. The Marvel cannon of characters is so vast, there are many I wish we could've had the opportunity to see.
P.S. Go check out Avengers: Earth's Mightiest Heroes season 2 when it picks up on Disney XD Sundays after Ultimate Spider-Man to get a gander at my day job exploits as a character designer for 2010.
