Sentinel Prime (Movie)

Sentinel Prime is a Prime, as given by his name. He preceded Optimus Prime and served as the captain of the Ark. He is believed to be one of the Dynasty of Primes.

""The needs of the many outweigh the needs of the few.""

- Sentinel Prime channels Spock.

Revenge of the Fallen
Sentinel Prime had once led an expedition that took him fourteen galactic convergences to get an echo of something or other.

It is currently unknown whether or not if he is one of the original Primes or if he's in the later Dynasty of Primes. However, he would appear to be one of the direct ancestors of Optimus Prime.

Sentinel Prime was also briefly mentioned in a rambling speech given by Sam Witwicky while under an All Spark fragment-induced trance.

Dark of the Moon film


Sentinel Prime has left Cybertron near the end of the war. Though it was believed that the space bridge technology he designed was to turn the tide of the war, Sentinel Prime actually sided with Megatron to rebuild Cybertron by finding an inhabitable world and enslave its occupants. However, the Ark, Sentinel's ship was hit and it eventually crashed on Earth's moon in 1961. As part of their plan, the Decepticons procceded to steal hundreds of pillars from the ship, leaving Sentinel and five pillars, including the Control Pillar behind as only Sentinel could use the pillars and he was in stasis lock from lack of energon.

After an engine part from the Ark is found on Earth, Optimus Prime and Ratchet travel to the moon in the Xantium and retrieve Sentinel from the ships hold, Ratchet scans him and tells Optimus: "His signs are faint." They also find five space bridge pillars. They put Sentinel in the Xantium. They then return to Earth.

On Earth, Optimus uses the Matrix of Leadership to revive Sentinel who attacks him at first out of confusion before calming down. Sentinel and Optimus proceed to explain the pillars functions and the threat they pose if the Decepticons get them to the humans. Sentinel is also unimpressed with Charlotte Mearing and her condesending tone towards him.



Optimus takes Sentinel, now with a Rosenbauer fire truck alt-mode on a drive to see the planet. Sentinel is impressed with the planet, comparing it to Cybertron before it was devestated by war. Optimus laments what could've happened if Sentinel led the final battle of the war instead of him. Optimus offers Sentinel the Matrix of Leadership, but Sentinel refuses it, saying that Optimus is now the teacher rather than him.

After Sam Witwicky learns of the Decepticons plot, he, Bumblebee, Dino and Sideswipe escort Sentinel back to base chased by the Dreads to protect Sentinel. Along the way, Dino and Bumblebee kill one of the Dreads and Ironhide shows up to kill the other two with the help of Sideswipe. Once at the base, Sentinel reveals his true colors and murders Ironhide with his cosmic rust blaster and retrieves the pillars, telling Mearing that he doesn't answer to her before fleeing.

At the National Mall, Sentinel opens a space bridge to the moon to bring in an invasion force of Decepticons and Optimus pleads with him to stop. Sentinel refuses and Optimus attacks him, but proves to be no match for Sentinel. Sentinel pins Optimus down and explains that he's doing this for the sake of Cybertron and that one day Optimus will understand. Sentinel tells Optimus that Optimus is lucky he didn't kill him and leaves. Sentinel procceds to send a message to the UN claiming that he's only after some of Earth's natural resources (in reality its human population too) and demands the exiling of the Autobots which leads to their apparent destruction on the Xantium at the hands of Starscream.



In Chicago, Sentinel meets up with Megatron on top of the Hotchkiss-Gould building where he sets up the space bridge pillars and activates them to bring Cybertron to Earth. Megatron is excited that they will save Cybertron together before Sentinel angrily tells Megatron that he's working with Megatron and not for him. Sentinel stays out of the fighting as Cybertron starts to arrive until Optimus uses Shockwave's cannon to shoot down the Control Pillar, temporarily deactivating it. After being goaded into battle by Optimus, Sentinel jumps down into the battle and fights Optimus. Soon, the combined forces of the other Autobots and the humans begin to overwhelm Sentinel, so he calls upon the Decepticon fighters to attack the Autobots, distracting them and allowing him to flee.



Sentinel doesn't get far as Optimus catches up to him and attacks him on a bridge. The two fight it out until Sentinel gets the upper hand and cuts off Optimus' right arm and injures his left shoulder. As Sentinel prepares to kill Optimus, he is attacked from behind by Megatron who was convinced by Carly Brooks-Spencer to help as Megatron would end up working for Sentinel. Megatron seriously wounds Sentinel so hard that his helmet gets knocked off before the reactivated space bridge is deactivated by Bumblebee destroying the Control Pillar which destroys Cybertron and the remaning Decepticon forces. Optimus reenters the fight and kills Megatron before turning to Sentinel. Sentinel pleads with Optimus to understand why he had to betray him, but Optimus tells him that he betrayed himself before blasting Sentinel twice with Megatron's blaster, killing him.
