Dark Eggleo is a strange little critter with a bizarre altmode and a set of very evil teeth, with which he supports the Predacons through biting. Like many evil Cybertronic cats, he is an expert saboteur and among the oldest known Predacons.
- Dark Eggleo (Egg Beast, 1998)
- Japanese ID number: ED-1
- Dark Eggleo transforms from a mechanical sphere (ostensibly an "egg" mode) into a robotic lion. He is cast in translucent plastic except for a handful of chromed and die-cast parts. He has a non-removable keychain attached to his robot-mode back.
- The molds used for the Egg Beasts originated as toys from the pre-Transformers Takara Microchange line, where they were called "Meteor Robo". The keychains were added for their Beast Wars release, and were retained for the molds' use in Kiss Players.
