Scrapmetal (Movie)

The little one was a constructicon killed for spare parts to repair and revive Megatron.

Revenge of the fallen
The little one went down to the Laurentian Abyss with Long Haul, Mixmaster, Rampage, Ravage, and Scalpel to revive Megatron. When Scalpel requested for the spare parts, nobody brought the spare parts, so long haul and mixmaster threw the little one on the ground, and tore parts from him, killing him in the process. What great friends.
