Chompazoid

Chompazoids are a Cybertronian sub-species from the Aligned continuity family.

Chompazoids are a ravenous variety of Cybertronian. Chompazoids gain a temporary boost in power and strength from ingesting metal, but can be weakened by accidentally ingesting other materials such as plastic. To date, the only identified Chompazoid is the Decepticon Underbite.

Fiction

2015 Robots in Disguise cartoon

Underbite claimed to have eaten Nuon City in its entirety. He was imprisoned among other Decepticons on the Alchemor, and eventually escaped when the ship crashed on Earth. Pilot (Part 1) While the remains of the ship and also material at a local scrapyard were to his satisfaction, the organic material covering most of the planet was not, and he ran low on energy while trying to reach Crown City. He was later recaptured. Pilot (Part 2)

Notes

• Scraplets, which have been established to exist in this continuity, have similar properties, however it's unclear if they are classified in-universe as Chompaziods.
