Profile: A full fuel tank, clear skies and an open road, that's all Groove wants out of life.  He's relaxed and easygoing, the kind of 'bot that is typically happy no matter where he is or who he's with.  He doesn't like staying in any one place too long, so his attachments are short-lived.  But he considers every new experience enriching, so he'd just as soon move on to the next one anyway.  Although he's basically a loner, Groove never forgets he's an essential member of the Protectobots team in their struggle against the Decepticons.  But he detests violence of any sort, and often finds it difficult to reconcile his pacifist beliefs with his sense of responsibility to his comrades.  Certain that war is not the answer, he endlessly roams Earth's highways, hoping to find out what is the answer.

Abilities: In motorcycle mode, Groove can reach speeds of 140 mph with a range of 800 miles.  He's extremely maneuverable.  He carries twin vaporators, which shoot fine mists of various oxidizing, freezing, and corrosive liquids.  The mists are emitted in a concentrated beam, so that Groove can target the vaporators on particularly vulnerable areas such as joints and circuit connections, to disable his prey.  In robot mode Grove uses a photon pistol that shoots light bursts.  He combines with his fellow Protectobots to form the giant robot known as Defensor.

Weaknesses: When under attack Grove is often reluctant to fight back as he seeks a non-violent response.  this sometimes buts him in considerable danger.
