Lockdown (Transformers Film Series)

"You think you were born? No, you were built, and your Creators want you back!"

- Lockdown to Optimus in the film.

Lockdown is the main antagonist in Transformers: Age of Extinction. His alt mode is a grey 2013 Lamborghini Aventador LP 700-4 Coupe. His goal is to hunt Optimus Prime down and bring him to the creators of all transformers, an alien race known as the Creators. He is eventually killed in China by Optimus Prime, during the final battle between the renegade prototype Decepticons controlled by Galvatron and the Autobots.

Before Coming to Earth
Little to nothing is known about Lockdown's past before coming to Earth. What is known is that he is a mercenary and was hired by the creators of the Transformers, beings known as the Creators, to hunt down Optimus Prime and bring him back to them. He has also a deadly reputation among Autobots as both Optimus Prime and Ratchet were terrified to see Lockdown on Earth. The Creators must've given him the bomb-like device known as  the seed  and he teamed up with Harold Attinger to hunt down the Autobots being provided unlimited access to Earth's resources. He finds the Autobot Ratchet, and asks him where the Autobot leader is, and when Ratchet refuses to tell, Lockdown simply rips out his spark.

Hunting Optimus Prime
After teaming up with Attinger, he went to Cade Yeager's farm and tried to attack the hidden Autobot Leader, who destroys the team sent by Attinger and escapes Lockdown's wrath. Lockdown would continue to presue Optimus, and Lockdown kills Cade's friend, Lucas, in their escape. But in the escape, he loses Optimus, much to his anger. Later on, while Optimus is fighting the human-made transformer, Galvatron, Optimus fails to realize that Lockdown has come to take Optimus. He shoots the Autobot in the back and takes him onto his large prison ship, where he reveals that he is working for the Transformer creators, who want Optimus back for an unknown reason. As a reword for helping him get Optimus, he gives the humans the Seed, a bomb that will turn a city wide area into Transformium, the mineral that all Transformers are made of. Lockdown is about to leave for space, when Optimus' human allies storm his prison-ship and rescue Optimus.

Final Battle and Death
"You saved a human instead of saving yourself. You bring shame upon us all."

- Lockdown during his final fight with Optimus Prime

Lockdown does not give up. While the Autobots are battling with Galvatron's forces, Lockdown activates a magnetic weapon under his ship and drops many magnetic and metal things onto the battling robots. Optimus destroys the weapon and engages Lockdown in a last battle. He battles Optimus and wins. However, before he can kill him, Bumblebee shoots Lockdown in his chest and punches him while Cade is able to shoot him with the alien gun and distract him, Shane & Tessa then wrap a hook around Optimus and help him grab Optimus' sword out of his chest, Optimus then defeats & kills Lockdown by impailing him right through the chest with the sword and dragging it upwards to his head slicing Him in half from the chest up, killing him instantly.

Trivia

 * He's the only transformer with green eyes as a sign of not being Autobot nor Decepticon. Although, Devastator has green eyes, and he is a Decepticon.
 * Lockdown's robot mode greatly resembles Optimus Primal's robot mode in Beast Machine with his face resembling the Quintessons' symbol, except with a scar.
 * Lockdown was voiced by Mark Ryan, who ironically voiced Autobots from the previous films such as Bumblebee, Jetfire & Ironhide (in the video game based on the first film).
 * It is unkown how Lockdown discovered the Creators.
 * Ironic to one of Lockdown's final words on calling Optimus a shame on saving a human instead of saving himself, Lockdown himself worked with a human to hunt down his own kind.
 * Despite the fact that he is not a Decepticon, his toys each have a Decepticon symbol, and the Transformers video game called Rise of the Dark Spark labels him as a Decepticon as well. He is also portrayed in the prequel comics as a former Decepticon.
