The rare Animagus (up for a re-write)

Harry, fed up with life on a dying planet, decides to leave for a better life on Pandora. As an Animagus with multiple forms he has little difficulty with fitting in. But while this new planet, is better than his old one it is not all without problems. Humans do what they do best; destroy to get what they need. Can he stop them? I don't own HP or Avatar
