Meloetta (Pirouette Forme)
I'd have to say Blaziken for the win.
Definitely Heracross. He's also my favorite Bug-type
So... can I assume these favorite topics will be made until all types get one? >_>
In any case, Tyrogue/Croagunk tie as favorite Fighters for me. The former because he seems to be a 'clean slate' whose evolution will depend on his training, and the later simply because I've taken a liking to frogs, as a result of being around my amphibian loving teacher too much.
