[@mattmanganon]: Looks good so far.  Only two suggestions so far.  

1)  Maybe make the Sg. Fury in WWII Nick Fury's father or grandfather, like in the Avengers: Earth's Mightiest Heroes animated series.  That way, it makes sense why Fury is still alive during the modern age.

2)  I know one of the other players (Gowi) is making a character sheet for one of the Invaders (Ms. America) who has been teleported to the present day.  While what you have so far it fine, you might have to edit it so that your two backstories are in harmony (all you would have to do it talk to him and I'm sure you both can find a compromise).

Otherwise, looks fine to me so far.
