- The HHR is a mass-produced Autobot bodyform from the Transformers: Rise of the Chevy Autobots portion of the Movie continuity family.
The HHR-type Chevy Autobot might not be very strong or fast, but there's brains for days under that chassis. Advanced processors let it out-think almost any opponent and exploit any weakness it can find to the fullest advantage.
It transforms into a Chevrolet HHR. Big surprise.
There are lots of it.
