Fictional character biography

edit

The Transformers

edit

In The Transformers episode "Five Faces of Darkness: Part 4", Rodimus Prime journeys into the Matrix of Leadership and witnessed a series of flashbacks of Cybertron's early days. One of them showed an unnamed blue robot who was a gladiator when the Quintessons ruled Cybertron. He led the rebellion that chased them off Cybertron. He led the Autobots in their victory against the Decepticons, and led them to victory. However, he was killed by Megatron at the start of the next war. Optimus Prime's predecessor as Autobot Leader wouldn't have a name until the American comic.

Transformers: Animated

edit

In the Cartoon Network television show Transformers: Animated, Sentinel Prime is a supporting character and an imposing figure within the Cybertron Elite Guard corps with a brash and smug demeanor as well as an obsession with following the rules of his superiors. After scanning an alternate mode as an earth disguise, he transforms into a pickup truck with a snow-plow attachment.[1]

Transformers: Dark of the Moon

edit

Sentinel Prime is the main antagonist of the 2011 film Transformers: Dark of the Moon. Originally appearing as one of the supporting cast members and Optimus Prime's former mentor, he takes on a more villainous role by making deals with the Decepticons to conquer Earth (Unicron) and even assassinates Ironhide. At the end of the film, Sentinel Prime and Optimus Prime duel with each other; only to have Megatron intervene and injure Sentinel fatally, which allows Optimus to ultimately kill him with a shot through his head.[2][a]

Transformers: More Than Meets The Eye

edit

Sentinel Prime appears as an antagonist in the comic Transformers: More Than Meets The Eye from IDW Publishing. Rumored to have been killed by Megatron during the early years of the Great War, Sentinel Prime later reveals that he had survived by imparting his knowledge into a smaller robot body and escaping in plain sight. Infiltrating the moon of Luna-1, he manages to outrun the Autobot guards there before taking mind control over one of them, Red Alert. 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.[3]

Transformers: War for Cybertron

edit

In the High Moon Studios video game Transformers: War for Cybertron, Sentinel Zeta Prime 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.[4][5] 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.[4][5] Sentinel was eventually executed by Megatron afterwards.[4] 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.[5]

Transformers One

edit

In the 2024 animated film, Transformers One, Sentinel Prime is voiced by Jon Hamm, where he is once again the film's main antagonist. He is the head of Cybertron and leader of Iacon, to fight the Quintessons and search for the Matrix of Leadership, but to no avail. The truth was discovered by Orion Pax, D-16, Elita-1 and B-127, when Alpha Trion reveals that Sentinel was just the assistant, until he betrayed and killed the Primes to steal the Matrix from them, which failed when it rejected him and disappeared. He allied with the Quintessons for power in return for Energon, and secretly removed the miners' transformation cogs to keep them powerless. However, Sentinel and his soldiers arrive, so Trion holds them off to allow the others to escape, resulting in him being captured and executed by Sentinel. In Iacon, Sentinel tortures D-16, who learns that he took the cog of his idol, Megatronus Prime, before being branded with his symbol. In the battle, Sentinel is seen on video before the treaty with the Quintessons and the murder of the Primes, causing all the citizens to turn against him. Eventually, Sentinel is killed by a furious D-16, who then takes Megatronus' cog, and renames himself as "Megatron".

In the video game Transformers: War for Cybertron, he is voiced by Troy Baker.[citation needed] In the film Transformers One he is voiced by Jon Hamm.[7]
