Huffer

Huffer is an Autobot who likely has little to complain about. He's strong, smart, and talented, but is also the crankiest and most pessimistic of the Autobots. But despite his poor attitude, and as the Autobots' resident tech specialist and construction engineer, he's capable of easily creating very complex tools to use on the battle field as well as structures that can easily take whatever the Decepticons and those nasty Predacons can throw or breathe at.

Following the restoration of Cybertron from the Great War, Huffer 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
Huffer appears in the Rise of the Dark Spark game for Nintendo 3DS as a support unit. Equipping him allows all Cybertron Autobots' Super Ability Energon costs to be reduced by half.
