Pretty much dead on. Only from what I've seen, The Flash doesn't really have any real strength: he just moves fast.

And that irks me. If he can move at the damnable speed of light (which Mark can't even get close to, don't be ridiculous) then why can't his punches, which have mass, have the right amount of force? And how the hell does he know what he's doing unless he's seeing everything in slow motion!!

Mark is effectively a more realistic flash. My original concept of the character only had limited control of his time perception, but seeing as there was a guy with omnikinesis, I beefed him up a bit for this RP :)
