I'll give you a hint: NYAAAAH!
She's actually my favourite character and design in this game. I've spent many hours trying to use her but for some reason, I cant gel with her. I know Kano is simplistic, but CSZ requires a bit of technical savvy to use so I dont think its that. It might be that online messes her up...she's one of those characters that's designed for offline only.
Incidently guys, i've been using Freddy in the lab and the guy is ridiculous. His combos are so powerful, his nightmare stance is really good and you create shenanigans with the cancelling, he has pretty good 50/50's and his zoning is so good. I guess my only gripe is, I like characters with a "get off me" move, which he doesnt really have, but EX Sweet dreams isn't too bad I guess.
EDIT: I have considered Jax, as he seems to have a similar playstyle to Kano, who I use a lot.
