Cool RHG mate. I have to ask though... does he really slow-down time or does he go into one of those super speeds that slows down time from his perspective while he is able to move freely at his own speed? The latter works better, since the first kinda just puts him in the same disadvantage as the opponent.
Anyways, good luck to you!
On the scarf thingie: Ask yourself, do you want a scarf? If yes, then do a scarf. If no, don't. :)
