Bunnie was once a normal rabbit until she was captured one day by Robotnik's SWATbots and put in the roboticzier.  If you can't think of someone who saved her, you must have brain damage.  Anyway, she was saved by Sonic during roboticzation, but she had been in there long enough to have her legs and left arm roboticzied!  Despite her abnormal appearance as being part robot, her robot side can come in handy.
