Profile, Abilities and Weaknesses description is from The Transformers: More Than Meets the Eye, published by Dreamwave Comics.

BIO: Roadgrabber's noxious cruelty is typified by a cold and sadistic fascination with the suffering of others.  He satisfies this grim curiosity to its full extent as a gunner in the Decepticon army, watching the after effects of his destructive sprees with detached interest. To amuse himself, he'll just blow the knee servos out of a fleeing Autobot and just watch them flail in agony before he'll finish the job. Many of his comrades are frightened by the impassive way Roadgrabber watches these horrors, but they're all amused by the entertainment he provides. Although he's no coward, Roadgrabber is deathly afraid of being injured himself, so he prefers to attack while hidden in the safety of his Pretender shell, until he's sure it's safe for him to come out and "experiment" with the survivors of his furious initial onslaught.

WEAPONS ABILITIES: Subject possesses great endurance, and above-average strength and intelligence. His outer shell is armed with dual-action cannons that alternate as freeze beams or flamethrowers (also useable in hovejet mode). He can reach speeds of 160 mph and crush foes between his front-mounted claws. As a robot, he is armed with a plasma rifle and can transform into a sub-orbital hoverjet.  Boosters in this mode allow him to reach speeds of 3,000 mph.

WEAKNESSES Subject has no outstanding physical weaknesses, but his cowardice can be a battlefield liability.
