In Transformers: Retribution, Hydratron-in its dormant state-was disguised as a continent on the planet Aquatron and served as the Quintesson base of operations. When their plan to invade Cybertron was jeopardized, they activated the Hydratron in an effort to eliminate Autobots and Decepticons alike. However, their plans were thwarted when Hydratron was caught in the explosion of their Spacebridge, though not before eliminating General Tyrannicon of the Sharkticons.
