Ooo Quicksilver... I loved the direction they took him in Days of Future Past.  Hmm.  Would be fun to make him rebelling against daddy.

As for characters of the here and now I'm just going to make Ant/Giant Man.  I just feel more like I know what to do with him more than Blade or Justice.  Though I just got Lego Marvel Superheroes and having to race Lego Blade riding on a pizza cart was amazing.

Edit: Also omg Kid Omega!  Hahahahaha what a dork!
