I'm quite sure that the Beast Wars Neo Encyclopaedia just says "rabbit". The box also says "Transforms from rabbit to warrior robot!!"

The sculpting probably does more closely resemble a hare, but the text says it's a rabbit. It looks a helluva lot more like a rabbit than Beast Wars Snarl looks like a Tasmanian Devil!! (i.e. BW Snarl does _not_ like a Tasmanian Devil )
