Gyarados (even though it is not Dragon type, it still resembles a Chinese dragon the most) Pangoro (well, it's a panda xD) Furfrou (the guardian, fitting her role as the gatekeeper of the Scarlet Mansion) Klefki (the keys) Arcanine (a Chinese legend, as stated in the old Red/Green Pokedex entry) Mienshao (a fighter that has a Chinese fighting style)
Squirtle (wearing the glasses as the team's mascot) Swinub (the closest thing to Boota from the series) Excadrill (to pierce the heavens with its drill) Golurk (an epic mecha to fly around on) Blaziken (because it's awesome) Victini (as the signature legendary, because Gurren Lagann always achieves victory)
EDIT: WOW, I completely missed the part where TC specified favorite game character. Whoops. (I thought favorite character was a very broad question.) Oh well, leaving this here because I like the idea.
Professor Snape Not necessarily my favorite character ever, but he's the first one I thought of.
Seviper, Deerling, Lilligant, and Noivern should be obvious picks to any Harry Potter fan. Mawile and Chandelure are my own arbitrary decisions. They seem to fit, and I couldn't think of any particularly better options.
