Faster than the human eye? That's way under a few thousand miles per hour. Sub-Sonic speeds are slower than 700 miles per hour, which is far away from a few thousand. If anything Blythe would be moving at a few hundred in short bursts. If you were standing still, looking across a street, you'd barely see a red sports car pass by at 100 mph. Negatmosk's character is definitely sub-sonic.

It also doesn't mean that the character would be able to punch with the force of a nuke. The Little Boy that was dropped in WW2 had a yield between 13 to 18 kilotons of TNT. Considering the speed we're talking? You're exaggerating by a lot dude. Chill.

Actually I underestimated how fast you would have to move to be invisible to the human eye, which is what the ability suggests. It's actually very ambiguous, you'd be better off just saying how fast you were going.

Don't assume I make baseless claims, I always research these things first out of interest. 

The nuke comment was a joke though, punching power is pretty difficult to calculate mathematically. Then again, looking at the sort of speeds necessary to become invisible to the human eye, maybe I was right, who knows. I'm not a physicist, i'm a goddamn historian
