Time to blaze a trail!
—Trailbreaker being awesome.
Trailbreaker is a happy, good-humoured Autobot who likes to make jokes or comment to lighten the mood when things get dark.
He is known to be friendly, happy, and upbeat, but whatever you do, don't ever, EVER, EVER, call him 'Trailblazer' or 'Trailcutter'. Starscream learned that the hard way.
He also served as the Autobots' Defensive Strategist, helping them out with defensive strategies. He also possesses the power to generate a force field, which can help protect his friends from deadly attacks.
He transforms into a camper truck, specifically a Toyota 4WD Hi-Lux. Trailbreaker also posses the ability to turn the back of his roof into a twin-mounted laser blaster.
Sadly, his life ended when Shockwave killed him and Wheeljack.
