Profile, Abilities and Weaknesses description is from The Transformers: More Than Meets The Eye, comic series published by Dreamwave Comics in 2003.

BIO: Skultgrin began his tenure as a Decepticon warrior with great promise. He was an incredibly powerful and intelligent war machine, but his reliance on logic became a detriment in his function as a siege warrior. His commanders demanded a more spontaneous, brutal approach, which the rigid and calculating Skullgrin couldn't comply with. The solution came when Skul!grin adopted a Pretender shell. The armor itself contained a "shell" program to bring out Skullgrin's basest most savage combat instincts. The program worked so well that Skullgrin is a completely different being when in his shell. The formerly calm and collected field commander of the Decepticon Pretender unit becomes a snarling and unstoppable beast that will stop at nothing to destroy his foes.

WEAPONS/ABILITIES: Subject is incredibly strong and highly intelligent He is an expert military planner and tactician as well as a capable warior. His Pretender shell amplifies his strength even further; in this mode, he wields a vibro sword that creates the optimum vibrational frequency for tearing through the armor of whatever target it is locked onto. In robot mode, subject transforms into an assault tank that fires shrapnel bursts from its turrets, whlich are also useable in robot mode. Subject also wields two "slagmaker" laser cannons in both modes; they can be combined to form a double-barreled cannon useable by the Pretender shell.

WEAKNESSES: In his shell, subject gradually loses his capacity for rational thinking. His wild fighting when he degrades into this state is formidable, but his ability to lead or plan strategy is greatly reduced.
