Because the Whizzer was created back when things didn't move very fast can I boost his speed up a lil' bit.
His max speed is only 100mph, which is a lot for a person and is a lot back then, preferably I'd like to be able to go over the speed of sound but I'll leave that up to you @The Kid Lantern.
Speed of sound is what, 740-ish mph? I can live with that.
