I could've sworn that style_parody had more posts than that. Or maybe another tag that had the same purpose was the one with more posts.

makes you wonder what their parties would be

Reimu:
Meowth, Electrode, Masquerain, Chingling, Bronzong, Arceus

Marisa:
Parasect, Starmie, Delibird, Shroomish, Luvdisc, Jirachi

Sanae:
Arbok, Politoed, Natu, Gardevoir, Altaria, Celebi

I think Marisa should have a Murkrow/ Honchkrow.

I'd go with a Mismagius, personally.
