Personality
Lockdown is a ruthless Cybertronian mercenary and bounty hunter who is feared even by the fearsome Decepticons. Once he has a target set, nothing stops him from destroying or capturing it.

He considers both Autobots and Decepticons to be like children for "making a mess out of the universe when he has to clean it up" (guess he doesn't consider decimating most of Hong Kong 'making a mess out of the universe').

He was sent by the mysterious 'Creators' to track down and bring Optimus Prime to them because they wanted him back. Upon his arrival to Earth, the bounty hunter teams up with Cemetery Wind and offers them a 'Seed' in return for Prime. Optimus in the end Splits his head asunder, saving Cade Yeager.
