Gears

If there's a negative angle to be found in any solution, Gears is the Autobot who will find it. Nothing makes him happier than having something to gripe about.

Transformers: Robots in Disguise
Following the restoration of Cybertron from the Great War, Gears was one of the many Autobots blacklisted by the new High Council for being a supporter of Optimus Prime.

Transformers: Rise of the Dark Spark
Gears appears in the Rise of the Dark Spark game for Nintendo 3DS as a support unit. Equipping him allows all Cybertron Autobots to reduce the damage they take in head-to-head melee combat by 20%.
