Transforming into the car of the same name, the Trax is a model of Transformer produced by KSI, and is available in an array of fetching colors. They've sure built a lot of them, and they'd probably make for a pretty handy army if you needed one...
Multiple Traxes were among the KSI-built Transformers that Galvatron took control of. One of the Trax drones shot down the Autobot ship during the Battle in Beijing when they attempted to retrieve the Seed from Joshua Joyce, while others were killed by Hound when he was defending the humans and others were killed during the charge of the Dinobots.
ALTERNATE MODE
As the name implies, the Traxes molecularly transform into different colored Chevrolet Traxes.
