hmmm... He'd have to be able to sprint twice as fast as an olympic level sprinter to run a mile that fast.... which he may be able to do consider he has peak human everything, stronger than a power lifter combined with greater agility than a gymnast would make him pretty damn fast
It was inevitable.
One day, it's gonna happen to Batman too. You'll see. Slowly but surely. It's already happening with his costume: look how much more tech it is than it was 30 years ago. First the costume...eventually the body.

Maybe... but with Iron Man it should have happened a while ago. Tech saved his life from shrapnel, got him out of a POW camp, replaced his heart and now it's throughout his entire body.
I think it's a good, logical move for Iron Man to become more and more machine (up to a point)
This "Extremis" thing is messing with his mind to the point that i can see him becoming a big enough threat that the Avengers have to go against him in the not too distant future... after that he'll get rid of it and revert back to regular Iron Man (probably)
If you ask me, it would have been logical for Batman to become "Iron Man" a long time ago. He's got so much tech from not only Wayne Enterprises but also his alien JLA buddies it's ridiculous. For example, the fact that he still wears kevlar is pretty stupid when he could easily strap himself with a Mother Box.
we consider it a power because it is rare. it is like photographic memory.
it is not considered a 'super' power though. it is not considered a mutation. and he was born with it.
Captain America has an upper hand over Taskmaster though. Cap. got injections in order to be what he is today. Taskmaster had to work his ass off if he wants to pull off the moves Spider-Man and people of the like do.
Just by mimicking them does not mean he can fully pull off the moves and stay in shape. His body has to be in superb physical condition and have a good degree of contortion if he wants to get any move right without hurting himself. Hes not Superhuman hes Human.
