Energon eater
From Transformers Wiki
Dwelling in the depths of space, Energon eaters feed off the energon from the ships they manage to catch. They hunt largely by scent, being able to smell flowing energon. They can also channel energon out through their tails, the more wily of them using the ability to repower ship computers so that other ships are drawn in by their distress calls.
Fiction
Rescue Bots cartoon
The Sigma and its crew of Rescue Bots followed a distress call to a damaged ship, only to be confronted by an Energon eater. Heatwave, Blades, and Boulder headed back towards the ship, but were cut off by the creature until Chase rammed it using the ship. With everyone back on board, they realized that the Energon eater would continue hunting them, so they put themselves in stasis and shut down the ship to eliminate the energy signature, and the beast left them alone.
Some time later, after the Rescue Bots had made a home on Earth, Chase had the urge to again try to aid the stricken ship. He and Boulder took the Sigma back to the scene, only to find that the Energon eater had been powering the derelict's computer to make it produce a distress signal. The pair managed to evade the beast, but it drained the Sigma's power core, leaving the ship dead. Chase and Boulder were forced to trap the Energon eater and use power from it to reenergize the ship. They took the creature, dubbed "Sparky" by Chase, back to Earth and presented it to Optimus Prime. Unfinished Business
A small energon eater encapsulated in a metal shell was struck by a spaceship piloted by Bumblebee. He crashed on Earth, and after Boulder extracted the shell from the stricken ship, the energon eater emerged and headed into the Rescue Bot Training Center's network of air ducts, which it proceeded to use to attack the Rescue Bots and drain their energon. Though it managed to put Heatwave, Chase and Boulder into stasis lock, Bumblebee and Blades lured it to the spaceship where they sprung a trap. The creature was put into a stasis pod and Bumblebee took it with him when he left. Uninvited Guest
