The Creators (Transformers)

"No you were built and your Creators want you back."

- Lockdown The Creators are the unseen Bigger Bads of the movie, Transformers: Age of Extinction. They are the creators of all Transformers and they sent their own personal bounty hunter, Lockdown, to capture the Autobot leader Optimus Prime, whom they desire for some reason. It is clear that very few to none of their creations know of their existence. At the end of the movie, Optimus Prime blasts off to space and sent a message to the Creators: "Leave planet Earth alone, cause I'm coming for you".

They will return in ''Transformers: The Last Knight. ''

Age of Extinction
Lockdown reveals to Optimus Prime that all Transformers were not born, but they were built by a race of organic alien beings. Optimus is confused over this, since both Autobots and Decepticons always believed that they were created by the AllSpark cube having given life into them.

Due to the destruction Lockdown caused nearly bringing the entire human race to extinction using the Seed, Optimus knew it was too dangerous for him to remain on Earth because he was the sole reason why the Creators sent Lockdown, and he flew off into space to search for his Creators and force them to refrain from attacking Earth.

The Last Knight
In the Super Bowl LI commercial for The Last Knight, it is revealed the Creators have brainwashed Optimus and are making him fight Bumblebee.

Engineering
The Creators are very good at engineering, as they created the planet of Cybertron and all of its inhabitants, who were not only capable of emotions, but were able to engineer their own warcraft and personalities of their own. This means that the technology of the Creators is far beyond human and cybertronian technology. It would also be logical to assume that they created all of this with the Allspark, further hinting of their great technology. They also engineered the Seed, a bomb that could turn anything into Transformium, the mineral that all Transformers are made of.

Power
It is unknown if the Creators possess any power or are just greatly technologically advanced. It is clear that their bounty hunter, Lockdown, fears them or is extremely loyal to them, but if Lockdown does fear them, it could be because they might possess supernatural powers, but this is unknown.

Trivia

 * It is unknown who the creators are but many fans currently believed that they are the Quintessons (or based from them), an ancient alien race of technorganic squids mentioned in the original Transformers, who created the Transformers for selfish reasons.
 * Many fans were even confused if it was the Allspark or the Creators who gave life to the Transformers. However, it is highly possible that the Creators themselves are the same beings who constructed the Allspark.
