The final boss of the game, Belger, is seen sitting in an electric wheelchair, though he is perfectly capable of walking without it. The exact reason why he needs the wheelchair is unknown. Some players theorize that Belger uses a wheelchair to trick his enemies into thinking that he is frail and helpless, or to discourage them from attacking him, as it would look uncivilized or cowardly to physically assault a "disabled" person.

In order to avoid the associated controversies, the wheelchair was digitally redesigned into an executive office chair for the game's western SNES release. The international SNES version also adds new frames of animation for Belger walking, just to make it clear that he isn't disabled. In the Japanese version, he has no walking animation and merely hops around the room.
