Continuing the early trend of stereotypical female characters, Boobs the Ba.... I mean, Rouge the Bat made her debut in Sonic Adventure 2. A treasure hunter and jewel theif who sucks at not getting caught, Rouge acts as a secret agent/spy for the Guardian Units of Nations(GUN), presumably so they'll expunge her criminal record. She is quite frequently given missions that often tie into the events of various games, and often she's just assigned to keep an eye on Sonic & pals... especially Shadow. However, this never stops her from going off on her own treasure hunting tangents, due to her obsession with shiny objects(but hey, who can blame her? They're SHINY!). Abilities wise, Rouge is a skilled martial artist who specializes in powerful kicks, strong enough to boar through rock and earth. She also has bat-like powers in that she can fly and emit hypersonic waves(called the Black Wave), and she has lately employed the use of gadgets like Bat Bombs. While Rouge tends to be flirtatious and deceptive with pretty much any male character, it has often been implied that she might've been created as a love interest for Knuckles, and later Shadow. The rest is just fan speculatoin/drivel, though.
