Rabbids
Serguei – Serguei is the main villain of Rayman Raving Rabbids. He is a large, black rabbid who abducted Rayman and the Globox kids and forced them to take part in the Rabbids Olympics filled with deadly challenges. In the end, Rayman manages to escape and free most of the Globox kids. It is unknown what happens to Serguei at that point, though his absence in further games suggest that he was relieved of his duties due to failure in keeping Rayman.
