Rez

Rez is a little known villain from a not very well known game called Gex, which was created by Crystal Dynamics for the PlayStation/Sega Saturn and the PC (the PC edition was released by Microsoft). BMG published the 3DO edition. There were two sequels to Gex. They were Enter the Gecko (PS1, N64, GB Color, PC) and Deep Cover Gecko (PS1, GBC, N64).
