Motto: A battle front is only as good as its supply line.
Unhappy with unglamorous role, but understands its importance... helps build Decepticons' massive energy-recovery installations. As vehicle, can carry 90 tons for 1200 miles, use a dual heat-seeking missile mount. As torso module, combines with fellow Constructicons to form giant robot Devastator. Can be goaded into fight in which he's overmatched.
