Look, Up In The Sky, It's A Flying "Secret Avenger"!

As expected, Marvel is continuing to tease us with yet another Secret Avenger. What makes this one different? This guy can fly. 

Hmmm...he excels through adversity? The pose first reminds me of Captain Britain, but he hasn't been wearing the helmet lately. He has shown up just recently when Paul Cornell blogged about the return of Cap Britain. He's even almost doing the same pose. Could it be him? Has he gone through enough adversity to make a quote about it. 
 
Who do you think it could be?
