Captain America for me. He is my favourite all around Superhero. He is the perfect choice to lead the Avengers into battle. I have collected Avengers Comics since I was a kid and Marvel Figures!
It kind of seems strange that there is no Wasp or Hank Pym seeing they were founding members, but I am just happy there is an Avengers film!
I hope they have a sequel with Ultron as the vilian then they can at the same time introduce the Vision.
All I can really say other than this is... bring it on. Avengers Assemble !!
