Demolishor is a military expert who serves Megatron through the Unicron Battles. He is a very trusted but sometimes very dim soldier who holds very true-to-spark values concerning loyalty and devotion to the Decepticon cause. These values sometimes collide with Megatron's ultimately selfish goals, and Demolishor finds himself struggling to reconcile the two.

Ultimately, though, Demolishor never abandons his devotion to the Decepticons as a whole, even if his faith in their leader is shattered.
