Couple odd questions

[KillWatch]

1) Any ability that does not have a physical correspondence can be negated (wingless flight, sonic speed, supernatural PS etc) can be negated. Anything with a physical representation (wings, huge legs for Enhanced Leaping etc) can not be negated

2) We are forgetting 1 thing, sound moves at the speed of sound sonic speed characters move at the speed of sound there is no drag on the on the character just because it has more mass. however dodging a sound attack I don't see unless it has some kind of visual element to it. Someone with sonic power (depending on how it manifests) can just scream. If the sonicspeed PC doesn't know what's about to happen and isn't up to full speed in time he is going to get hit

assume the sound is traveling at 700 mph
700=Spd 1000=1000' per second so unless they are about 1/5th of a mile away when he starts screamin he is going to get hit (I don't remember the range of the scream but the runner is going to get hit if he is within the blast radius and does not get an action before the attack)
