OCD- Centurion, the American Superhero

Another redesign of another original creation.  I decided to name him "Centurion" as a bit of a placeholder name, since I wanted something that was strong, but not too obvious or simple. 

Nothing much in regards to changing his original look, since I was pretty satisfied with the overall look even after I revisited it.  The only thing I changed is that I simplified his helmet so that it looks more like something that I would create rather than trying to copy how someone else might draw it, which is what I think I was trying to do at the time of the original drawing.

As for his origin/ powers, again I didn't give it too much thought when creating him.  But I did have the idea he'd be the standard "flying brick" type superhero- superstrength, flight, invulnerability, ect.  But since I like doing something a bit unique where I can, I'd try to make it that he can really only choose one power at a time, or if he wants to use one ability to it's fullest, he has to limit the others.  For example, he could increase his strength, but it would come at the cost of his flight or invulnerability.  That sort of thing.
