Err, Robyrt. I think Spaz can reach the powerupped blaster just as well as Jazz can.

To make things clear, both the characters have two special moves:
Jazz: Helicopter ears, Uppercut
Spaz: Double jump, Karate kick

I agree with you though. I don't think either that Jazz stands a chance.
Anyone up for doing a Jazz speedrun? It doesn't have to be perfect, I died about four times in mine.
