Coily

Coily is the major antagonist of the Q*bert franchise. Coily's main goal appeared to be to bite Q*bert. He always started off as a Coily egg, which bounced down to the center of the pyramid, where it hatched. Then, Coily would pursue Q*bert. The only way to get rid of Coily was to use a Transport Disk, which would cause Coily to jump right off the edge.
