I'm trying to get 18 characters: 12 starting Pokemon, 4 sub-bosses, the final boss, and an Akuma-style secret boss.
Problem is I'm not sure what kind of Pokemon I should pick. I know I want at least 1 Pokemon of each type, and for the Pokemon to all be as varied as possible, but other than that I'm not certain.
Some ideas I've toyed with are that one of the starter characters be a Throh/Sawk tag-team, and that Metagross and a Dragon-type be two of the sub-bosses. The final boss I considered Mewtwo, and the secret boss be either a Dark- or a Ghost-type.
Anyone got any advice?
