Cleaner

The Cleaners are life-forms from the Prime portion of the Aligned continuity family.

The creatures known as Cleaners live in Aquatron's oceans, travelling in massive schools. They spend most of their time trawling the underwater pipes and pumps, consuming garbage buildups and excreting solvents to keep the autonomous Energon-processing facilities humming. They come in a variety of sizes.
