9. Mouse Batman

Possibly my favorite incarnation of Batman is Batmouse. Part of the Justice League parody, Just'a Lotta Animals, Batmouse is joined by Super Squirrel, Wonder Wabbit, Green Lambkin Aquaduck and more! Why Batmouse is in fact a mouse and not a...well a Batbat, I don't exactly know. It is made especially odd once you consider that his side kick Boyd the Robin Wonder (Do you see what they did there?) is a Robin. At least he didn't have it as bad as Hawkmoose. Poor Hawkmoose. Do you want to know possibly the most insane thing about Batmouse is? He actually exists in DC continuity. He isn't some character that was just on a cereal box one time. He lives on Earth-C-Minus which is considered fictional on Earth-C (or Earth-26). But Earth -2 is considered fictional to Earth -1, so their world is no less legitmate. So my question is, where is the Batmouse stand alone?
