i'd be a shapeshifter... i often brainstorm stories and one of the ideas I came up with is if everyone with a fursona turned into their fursona... my mind started thinking of things like xmen, there'd be a lot of discrimination, fear, riots, violent acts etc... in which case i'd prefer to shapeshift... xD
but aside from that it'd just be plain funny... blue dragon flying over a building you get to the otherside and only see a lanky white guy standing their looking like a dork
