Rez Beasts or Mutant Drones are strange enemies found in Rezopolis in Enter the Gecko and one of Rez's creations. Arguably the ugliest enemies in the game, the Rez Beasts appear to be cyborg cyclops. At first it seems they don't notice anything but if the player gets close to them then they will stop, plug themselves down and start firing an electric ball at Gex. Attacking them is difficult somewhat when they are charging but one attack is all that is needed to defeat them. Like the Frankenstein Monsters, they don't vanish once they are attacked until they leave the room where they attack the beast. When lying on the floor, defeated, they can be repeatedly hit producing a 'squeeky toy' noise. Their faces consist of a TV with a gaint eye floating in it.
