Transformers: Dark of the Moon Sentinel Prime is the main antagonist of the 2011 film
Transformers: Dark of the Moon. He is established as Optimus's teacher and the previous leader of the Autobots. Optimus and the other Autobots find him on the Ark, an Autobot spacecraft that crashed on Earth's moon after being damaged during its escape from a wartorn Cybertron. Though Sentinel initially appears as a noble character, refusing the Matrix of Leadership from Optimus and asking him to take on his role as a mentor to the Autobots, he is revealed to have allied centuries prior with Megatron and the Decepticons to conquer Earth (
Unicron) and even murdered Ironhide. Sentinel Prime takes over the city of Chicago by using Decepticon pillars to bring Megatron's army to Earth, while usurping Megatron as leader of the Decepticons and planning to use the pillars to bring Cybertron itself to Earth. At the end of the film, he and Optimus Prime duel with each other, culminating with Sentinel ripping Optimus's arm off and nearly killing him, only for Megatron to intervene and injure Sentinel fatally to reclaim his leadership position. After Sentinel is defeated, Optimus takes the opportunity to rip Megatron's head off, while Sentinel begs for his life, only for Optimus to proclaim Sentinel "betrayed himself" and blow up his head with Megatron's shotgun.
Transformers: More Than Meets The Eye Sentinel Prime appears in the comic

They both mastermind a plot to send the reanimated Titan giants to attack Cybertron but Sentinel is eventually shot down by Red Alert, who turns on him. Sentinel then falls into a large hole by accident, killing him from the impact.

Transformers: War for Cybertron, Sentinel Zeta Prime is voiced by Troy Baker. He acts as a vassal for the Quintessons and rules over Cybertron; he eventually manages to expel the Quintessons from Cybertron with the help of the population of Cybertron, who had formed a resistance. He was later imprisoned by the Decepticons during the early days of the Great War, and the position of Prime was granted to the lowly librarian Orion Pax, who became Optimus Prime. Sentinel was eventually executed by Megatron afterwards. In his dying breath, he was able to talk to Optimus Prime and Jazz who had just come from receiving a distress signal from his prison.
Transformers One In the 2024 animated film
Transformers One, Sentinel Prime again appears as the main antagonist. He is portrayed as the leader of Iacon City, the last surviving Prime after the war with the Quintessons killed the other Primes. Sentinel routinely travels to the surface of Cybertron, claiming to be searching for the Matrix of Leadership after its disappearance at the end of the war. However, due to the efforts of the rogue
Orion Pax,
D-16,
Elita-1 and
B-127 on Cybertron's surface, the truth is revealed; Sentinel is delivering most of Cybertron's Energon to the Quintessons in exchange for remaining in power. Fleeing before they are discovered, the four stumble onto the remains of the Primes, leading to the reactivation of
Alpha Trion. The Prime, thought dead along with the others, reveals that Sentinel was just an advisor to the Primes until he struck a deal with the Quintessons: he would help defeat the Primes, and he would be allowed to rule Cybertron in exchange for Energon shipments. Agreeing to the deal, Sentinel and the Quintessons lured the Primes to an isolated location and ambushed them with overwhelming numbers, leaving Alpha Trion, heavily wounded, as the only survivor. Sentinel then attempted to claim the Matrix of Leadership, but it rejected him as unworthy and disappeared. Sentinel then took the transformation cog of Megatronus Prime for himself and returned to Iacon City, branding himself as the last surviving Prime. During his ascent to power, Sentinel had the transformation cogs of most of Iacon's population removed in secret, including those of Orion Pax and D-16. They, along with Elita-1 and B-127, are gifted the remaining transformation cogs of the dead Primes by Alpha Trion, and vow to return to Iacon to expose Sentinel's lies. However, the group is attacked by Sentinel and his forces. In the resulting battle, the four transformers escape when Alpha Trion sacrifices himself, which leads to them meeting the Cybertronian High Guard, having been surviving in exile of Cybertron's surface, performing raids on Sentinel's forces. Just as D-16 is about to rally the High Guard, they are found and attacked by Sentinel's forces, with a majority of the High Guard along with D-16 and B-127 being captured and taken back to Iacon City. While Orion Pax, Elita-1 and rally the remaining the High Guard, Sentinel tortures D-16 by branding him with the symbol of Megatronus before revealing that he personally took the fallen Prime's transformation cog for himself. Before D-16 and the other transformers can be executed, Orion Pax, Elita-1 and the High Guard appear and engage Sentinel's forces. They transmit the evidence of Sentinel's treachery to all of Iacon, distracting him and allowing an enraged D-16 to break free of his bonds and attack Sentinel, besting him in combat in front of all of Iacon. As D-16 attempts to execute Sentinel, Orion Pax is instead heavily wounded and falls into the depths of Cybertron. D-16 then destroys Sentinel by ripping him in half, takes the transformation cog of Megatronus Prime, and declares that he is now Megatron and all symbols of Sentinel Prime and his supporters in Iacon City must be destroyed, which begins the War for Cybertron. ==Merchandise==
