SuperNova is good but I think you can put "super" before almost any player's name to have a good nickname. How about Nova-Viva or Viva-Nova? (Viva is an Italian word used to express acclamation, salute, or applause.)
I like Supernova best of the ones I've seen. Jack Tripper is pretty funny, though, so that might be alright too.
Hey guys while I was thinking a nick for STEVIE, I thought of something good for V-Span toooo!!! V-Specialiiist . And for Novak:....... .. .. ... Doctor 3vie
