Blaze PKMN Trainer

Well, here's a sprite of the all powerful pyro-kitty, Blaze! (Uh oh... Silver's wearing his Lance outfit and glaring at me... I'd better stop joking...)

Well, Blaze will be a powerful gym leader. She'll be a fire-type specialist. (Duh.)

Try and guess what character Blaze is dressed as!
(Also, I'm planning on Silver being it the story, but I need a decent explination of how he got to that time and why. Vacation? Disaster? Chaos without the Control part? IDK, so any possible explinations would be appreciated.
