hmmmmmmm. that's a hard one but i think that i would say speed cause then i could get to all my classes on time and i'd never be at the back of the lunch line and get cold pizza
If I had super-strength, then I could pummel my enemies, but then they could dodge me with their speed. If I had super-speed, I could tire out the enemy, he would never be able to hurt me, and I could do lots of exercises. *nods* Superspeed it is.
