Yeah. We don't know where we got this from either.
Overload transforms into a Komatsu HD465-7 articulated dump truck. He forms Devastator's back and shoulders. During the climatic battle in Egypt, Overload combined with his fellow Constructicons to make Devastator. He was killed when Devastator was targeted by a railgun. Yeah. Shortest synopsis ever. Don't worry. Overload gets a toy. A friggin Legends toy. Yeah. Hasbro gave toys to the Constructicons only with more screentime, but Long Haul and Mixmaster were cheated.
