I'm Rouge the bat, who possessed Amy Rose (a pink hedgehog) when she accidentally wore my "Proxy Plate". The Proxy Plate is a my heart shaped chest plate that has my soul inside, meant for possessing other people. It can move around on its own and merge with other clothes to make sure the host wears it. The host body will endure physical transformations to mimic my own body-build. My proxy plate attached itself to Amy's dress, and I took her over once she put it on. Just call me Amy Rouge.
