Transformers Prime Season 1 Episode 16

During a battle between Bulkhead and Breakdown, Breakdown is captured by Silas and his MECH agents so they can dissect him to better understand Cybertronian technology. Figuring Megatron won't mount a rescue for a fellow Decepticon, Optimus Prime assembles his team to do so, much to Bulkhead's shock. Initially, he refuses to help his archenemy, but Miko convinces him to go so he can get a long awaited rematch against him. Bulkhead is first to find Breakdown and the two must work together to escape from MECH.
