- The Dinobots are an Autobot subgroup in Age of Extinction portion of the live-action film series continuity family.
The Dinobots are legendary warriors who traveled the vastness of space and time in the Knights' Temenos. However, they lost control of their ship after it was taken over by the mercenary bounty hunter Lockdown. He then imprisoned them in their own ship.
- "Legendary warriors, the powers that created us now want us all extinguished. We must join forces, or else forever be their slaves. So today you stand with us, or you stand against me..."
- ―Optimus to Grimlock.
The Dinobots were imprisoned in the center of Lockdown's ship.
The Autobots commandeered it after Optimus remembered the ship, but they were soon shot down by Galvatron's army and separated when it crashed outside Hong Kong.
Hearing a call for help from their fellow Autobots trapped in the city, Optimus Prime frees the Dinobots. At first they do not see optic-to-optic, and the Dinobots' leader, Grimlock, fight with Optimus. Optimus soon defeats him, and following their leader, the rest of the Dinobots, Scorn, Slug and Strafe, agree to working with the Autobots. The Autobots mount up in their new steeds and ride into battle to assist their friends.
