Sentinel Prime is the name of several fictional characters in the various Transformers series. First mention of Sentinel Prime was in issue #65 of the US Marvel Comics Transformers series, where he was mentioned to hold the Autobot Matrix of Leadership before Optimus Prime. Sentinel Prime has since appeared in a variety of forms as either Optimus Prime's mentor or friend. Fun Publications has also had a character in their comic called Sentinel Major, who is based on the Transformers Animated version of Sentinel Prime.

Animated series 
Sentinel Major was originally one of the Quintessons' slave robots on Cybertron around twelve million years ago. Unusual among his consumer goods brethren, Sentinel Major was equipped for combat and was forced to participate in gladiatorial games for the Quintessons' amusement, wielding a spiked ball-and-chain weapon and a tire-shaped shield. He was once defeated in battle by Prima, who attacked their Quintesson masters when their match was over, only to be destroyed himself.
Subsequently, the consumer goods robots rose up against the Quintessons in a rebellion that ultimately forced the aliens off the planet. Sentinel Major survived this clash, but he and the rest of his race—now dubbed "Autobots"—were robbed of any chance of peace when the military hardware robots, now known as "Decepticons", set their sights on conquering Cybertron for themselves. Two Autobot leaders fell during the war that ensued, and Sentinel Major inherited the Matrix of Leadership and became Sentinel Prime, leader of the Autobots. Under his leadership, the Autobots realized that they would never be able to defeat the Decepticons with firepower, and they turned instead to stealth, reconfiguring their bodies to be able to transform into other forms. With the power of his new ability, Sentinel Prime defeated the Decepticons' leader, and the Autobots won the war.
The ensuing period of peace was known as the Golden Age of Cybertron, but, around nine million years BC, the Decepticon threat re-emerged when they too adopted transformation, and coupled it with robot-mode flight powers. One of the first of this new breed of Decepticons, the malevolent Megatron, killed Sentinel Prime in combat. As he died, the dying Sentinel Prime handed off the Matrix to Alpha Trion, who kept it safe until the emergence of the next Autobot leader, Optimus Prime.
When Rodimus Prime journeyed into the Matrix in 2005, Sentinel Prime was the sixth guide he encountered. Sentinel Prime recounted the development of transformation, the Autobot victory in the war and the rise of Megatron.
Marvel Comics 
Sentinel Prime originates from the original Marvel Comics Transformers series. Sentinel is the immediate predecessor of Optimus Prime, and was killed in battle on Cybertron. He is glimpsed in issue #150 of the UK comic, passing the Autobot Matrix of Leadership on to Optimus Prime. It was not made clear in this continuity who or what caused his death. His appearance resembles Rodimus Prime.
His name is taken from issue U.S. #65 (UK #290) in which all the past Matrix holders are listed and he precedes Optimus Prime.
Dreamwave Productions 
Sentinel Prime died during the early stages of the civil war on Cybertron, supposedly killed by Megatron in single combat. In this continuity, at the time of his death, Sentinel Prime was not in possession of the Matrix.
The only image of him is a yellow hand as seen in the first issue of Dreamwave Productions' The War Within. When Megatron later battled Optimus Prime for the first time, he states that Sentinel tried to talk him out of his evil ways.
IDW Publishing 
Sentinel Prime receives a bit more history in the IDW Publishing's 4-issue miniseries, The Transformers: Megatron Origin. After Megatron's attack on an Autobot senator and subsequent escape, current Autobot leader, Sentinel Prime vowed to hunt them down, despite his lack of concern over the senator's fate. Sentinel took a direct interest in the underground bloodsports that Megatron was involved in, determined to shut them down and declared that Megatron "will hang". Megatron's followers were eventually captured by Sentinel's forces and Sentinel taunts Megatron before imprisoning him. However, the apprehension of the Decepticons turned out to be part of Megatron's ruse. Starscream and Soundwave killed the Autobot Senate, and a full scale revolution erupted in Kaon. Desperate to stop them, Prime donned Apex armor and confronted Megatron, but was defeated and beaten to within an inch of life by the Decepticon leader. Note: Sentinel's name was initially spelled as Sentinal Prime, later revealed to be a mis-print introduced at the lettering phase.
A glimpse of Sentinel Prime was also seen in The Transformers: Spotlight issue featuring Optimus Prime. He is again the Matrix-holder preceding Optimus Prime, and succeeding Nova Prime. In bonus art following the story, Sentinel's alternate mode was revealed as a yellow and orange Cybertronian truck. In Spotlight: Blurr (November 2008), it is revealed in between Sentinel and Optimus, there was a Prime named Zeta.
Transformers Animated 
Sentinel Minor, before his days as a Prime
|Sub-group||Deluxe Vehicles, Elite Guard|
|Function||Autobot Elite Guard Captain|
|Motto||"Without law, all is chaos."|
|Alternate Modes||Cybertronian Truck, Snowplow Truck|
|English voice actor||Townsend Coleman|
|Japanese voice actor||Junichi Suwabe|
In the series Transformers Animated, Sentinel Prime is a hotheaded member of the Cybertron Elite Guard. Sentinel's main weapon is a shield called the Skyboom Shield, that is able to generate force fields and can be used offensively when thrown. He also wields a laser lance, and can activate a battle mask when needed.
In December 2007, drawings were leaked on the internet of Sentinel Prime's vehicle appearance in the Transformers Animated television series. He turns into a snow plow truck. Derrick Wyatt stated that the character was originally meant to be named Rodimus Prime, after Optimus Prime's G1 Successor. However, the idea of Rodimus being portrayed as arrogant and rude was dropped in favor of Sentinel Prime. An interesting note is that Sentinel's robot mode bears a strong resemblance to The Tick, which was a result of Townsend Coleman (the voice of the animated Tick) being cast in the role.
Animated series 
Once known as Sentinel Minor, he was the drill sergeant training Bumblebee, Wasp, Bulkhead, Longarm and Ironhide, who were recruited into the Autobots. When it appeared that Wasp was a secret Decepticon spy Sentinel Prime arrested the innocent Autobot, not realizing it was Longarm who was the traitor. It was also revealed that he didn't like Ultra Magnus because of the recruits he is forced to train and was friends with Cliffjumper.
Sentinel Prime and Optimus Prime have been rivals since they attended the Autobot Academy together with Elita-1 (whom Sentinel had feelings for) as seen in a flashback in "Along Came a Spider." Things changed when Sentinel brought the others to an organic planet to find a lost Decepticon warship, only to be attacked by giant alien spiders that inhabited the planet and the ship exploded during the confrontation. In spite of Sentinel's pleas, Optimus was forced to leave Elita-1 on the notion that she was killed in the explosion, both unaware of her transformation to Blackarachnia. Since then, Sentinel never forgave Optimus for the incident and developed a racial fear of organics, believing that they'd all be the same as those spiders. During the inquiry, in which both he and Optimus were accused of going to an unauthorized organic planet, Optimus took full responsibility as the senior cadet, which led to his expulsion from Autobot Academy and barred from assuming any Elite Guard position. Sentinel on the other hand, who denied being the one who caused the chain of events, wasn't punished for his involvement and later rose to prominence in the Elite Guard.
At the beginning of the series, when Optimus tried to contact Autobot High Command, Sentinel refused to allow him to see Ultra Magnus until Optimus showed him the Allspark.
Sentinel Prime (alongside Ultra Magnus and Jazz) arrived on Earth to look for the Allspark. He had Prime's crew "decontaminated" from organic infestation. He didn't believe Prime's stories about the Allspark being destroyed or their encounters with Decepticons. He did end up attempting to fend off the Dinobots on Dinobot Island when he provoked them. After the incident at one of the factories owned by Isaac Sumdac (in which the fragment of the Allspark was the cause of this), Sentinel Prime threatened to make sure Optimus was charged with treason for destroying the Allspark, however Optimus had grown tired of Sentinel's arrogance and reminded him despite being an Elite Guard washout, he and Sentinel still shared equal rank and told him he was on "his turf now". Ultra Magnus stated to Sentinel Prime that he can learn a lot of things from Optimus Prime, such as loyalty.
In "Return of The Headmaster", Sentinel Prime got a lesson in humility after his body was taken by the Headmaster and he was forced into a partnership with Optimus to get it back.
In order to improve morale, Sentinel tried to force Optimus Prime to declare that they hadn't encountered any Decepticons, but Optimus refused to do so. Sentinel then tried to bribe him with re-entry into the Elite Guard; when he didn't comply, he placed Optimus into custody. Sentinel later refused to believe that Ultra Magnus and Jazz were walking into a Decepticon trap, so Optimus tricked him into a pair of stasis cuffs in order to save the day. Sentinel soon learned Prime was telling the truth when Starscream fell from the sky. It was shown that he choked up under pressure and fear at the sight of a Decepticon.
He appeared again chasing Wasp in space, even though it seems that he may have forgotten all about Wasp. It is also shown that since he can still use his Cybertronian vehicle mode while chasing Wasp. Unfortunately, he let Wasp get away when he fell off the suddenly activated Space Bridge.
Later, during the episode "Where Is Thy Sting?" he had Jetfire and Jetstorm following his orders to find Wasp. His dislike for the planet Earth and organics increases, as he finds himself unable to adapt to driving in the rain. He kept ignoring Optimus when he said that Longarm was the real traitor until Wasp confessed that he and Bumblebee switched appearances.
In "Five Servos of Doom" he had seemingly captured Sunstorm, Blitzwing, Lugnut, and Swindle (though he admitted that since Swindle was trapped in vehicle mode he simply had to pay a fine and have him towed) by himself. Optimus, Jazz, and Prowl were extremely doubtful that he could have accomplished such feats, and set out to find how he did it. After following Sentinel Prime it was revealed that it was Lockdown who was capturing the Decpticons and trading them to Sentinel for Autobot upgrades. After being betrayed by Lockdown, who was working for Ramjet, Sentinel ended up becoming the Clone's hostage and shield, taking most of the Autobots attacks on himself and ending up face-first in the ground. Optimus covered for Sentinel when reporting to Cybertron, giving credit for the captures to Prowl, but he assured Sentinel that they would "talk it out" when the crisis was over.
In "Predacons Rising" Bumblebee, Jetfire, Jetstorm, Optimus Prime and Sentinel Prime chased Wasp, but lost him to Swoop while bickering about what to do with him. Following Swoop to Dinobot Island, Sentinel encountered Blackarachnia, learning the truth about what happened to her as Elita-1. Disgusted by what had happened to her, Sentinel refused to accept her as the Elita he knew and attempts to kill her before Wasp (newly changed into Waspinator) intervened. After Blackarachnia sacrificed herself to save the Autobots from a transwarp energy-overloaded Waspinator, Sentinel expressed regret for what had happened to her, even taking blame for what had happened that day, and burying the hatchet with Optimus. Sentinel and the Elite Guard returned to Cybertron soon after, with Sentinel having to take command in the wake of Shockwave's attack on Ultra Magnus.
In "Decepticon Air" Sentinel interrogated the captive Decepticons for information concerning the recent Space Bridge attacks. Sentinel's ego and recent rise in ranks gets the better of him. In order to get back to Cybertron quickly so he can take over as the new Magnus, he ordered Jazz to take the ship through an ion storm. The resulting energy discharges free Swindle from his locked vehicle mode, which allowed the other Decepticons to take over the ship. Sentinel was forced to call for help, specifically for Optimus with a secret Academy code. The Decepticons were defeated and recaptured, though Swindle and Lugnut escaped. In gratitude, Sentinel offered Optimus the Eite Guard position he would have to vacate in order to become Magnus, but Optimus declined his offer, stating that there was still work to do on Earth. So he drops him off back to Earth, salutes to him then departs. On his return to Cybertron, Sentinel paraded the remaining Decepticons in front of the citizens before assuming command as the new Magnus.
In "This is Why I Hate Machines", Sentinel had apparently spread his hatred and fear of organics to all of Cybertron, as when Ratchet and police captain Fanzone arrive, nearly every Autobot who sees Fanzone is terrified. When Omega Supreme (piloted by Megatron, Starscream and Lugnut) transwarped to Cybertron, Sentinel ordered a full-scale assault on the colossus, only for the Autobot Council to deliberate whether to strike and possibly destroy Cybertron with it (as Ratchet had pointed out) or possibly miss a chance to end the Decepticon threat. Sentinel ignored the council's wishes to wait and prepared for a strike, claiming that as acting Magnus, he had to be prepared. However, he is chastised by Alpha Trion and Perceptor when his attack missed Omega, who had transwarped elsewhere. When Ratchet and Fanzone returned to Earth with the Magnus hammer, Jazz pretended to give pursuit, but instead chose to stay with the Earth team as Sentinel's bureaucracy had finally gone too far for him.
He was last seen in the third season finale, "Endgame, Part II", looking on at Optimus, Sari, the Autobots, Omega Supreme, the captured Megatron, Shockwave, and Lugnut, and Arcee with a jealous expression on his face.

In the Transformers film series, Sentinel Prime is a legendary warrior thought to have been lost long ago. He once led an expedition that took him fourteen galactic convergences to get an echo of something. Sentinel Prime is Optimus Prime's direct predecessor, mentor, and father figure. Sentinel's weapons include a shield, a double-bladed Primax Blade sword that can be folded into one, and a cosmic rust cannon that causes any metal object that it hits to rust into oblivion, as evidenced in the third movie when he shoots Ironhide once in the chest and twice in the back. His intention is to restore Cybertron to its former glory after the war, driven by desperation he turned him against his ideals by siding with the Decepticons. Sentinel Prime is voiced by Leonard Nimoy, who previously voiced the character Galvatron in The Transformers: The Movie.
Movie plot 
In the second film of the series, Transformers: Revenge of the Fallen, Sentinel Prime is briefly mentioned in the rambling speech given by Sam Witwicky while under an All Spark fragment-induced trance, with Sam mentioning a "mission" Sentinel led.
Sentinel Prime appears in the third film, Transformers: Dark of the Moon, as the film's main primary antagonist, revealed as a rogue Autobot later in the film. Though it was believed that the Space Bridge technology he devised was to turn the tide of the war for the Autobot's benefit, Sentinel Prime made a deal with Megatron to rebuild Cybertron by finding an inhabitable world and to enslave its occupants. However, the Ark, Sentinel's ship, was hit during the war between the Autobots and Decepticons and it drifted through space until it eventually crashed on Earth's moon in 1961. Before the impact, Sentinel hid himself in the crash vault with five of his Space Bridge pillars, including the control pillar, however he soon ran out of Energon and became incapacitated. His body was then recovered by Optimus Prime and Ratchet when the two Autobots come investigating the crash landed ship and was brought to Earth, where he was resurrected with the power of the Matrix of Leadership. Sentinel was distressed that hundreds of his pillars were missing, and warned Charlotte Mearing that the Decepticons could destroy Earth with the pillars. He later went out with Optimus to attend a tour of the Earth and admire its sunset, and declined Optimus' offering of the Matrix, due to the fact that he doesn't know much about the Earth.
Sam Witwicky discovers the Decepticons had the majority of the pillars and had planned for the Autobots to revive Sentinel, as he was the only one who could use the pillars to open the Space Bridge. Once he arrived back at their base, Sentinel confirms Sam's suspicions, but betrays the Autobots, kills Ironhide, transports the pillars to Chicago and rendezvous with Megatron. After teleporting hundreds of Decepticons to Earth, he has a confrontation with Optimus, but spares him, in the hope that he would recognize the moral of what he was doing. He demands the exile of the Autobots, who are apparently destroyed while leaving the planet in their space ship. Sentinel betrays Megatron and assumes command of the Decepticons and oversees the final phase of the plan in Chicago.
During the final battle, Sentinel battles Optimus, who faked his death, along with all the Autobots. Sentinel proves to be more than a match for the multitude of Autobots and human soldiers. He appears to have gained the upper hand and is on the verge of executing Optimus when Megatron intervenes and beats Sentinel into submission. The pillars are disabled before Cybertron can be teleported completely, which destroys the wayward planet. Megatron offers Optimus a truce, citing that his only desire is to be in command. Optimus, knowing what Megatron has in mind, refuses and swiftly kills Megatron. Sentinel pleads to Optimus to understand why he had to betray him, but Optimus refuses to condone it and promptly executes Sentinel.
The writing of Sentinel's character as well as Nimoy's voice over work for him was praised but; but he did receive some criticisms for being the only antagonist to have a development process.
Animator Scott Benza said Sentinel Prime had a face "more human-like than any of the other robots" in Transformers: Dark of the Moon, having a more complex frame and "a greater number of plates" so it could be more expressive. The film's main visual effects company, Industrial Light & Magic, based most of Sentinel Prime's features on actor Sean Connery, and after Leonard Nimoy was cast to voice the role, the effects were altered to incorporate Nimoy's acting as well.
Sentinel Prime is among the characters who appear in the flash game TRANSFORMERS CYBERVERSE Battle Builder Game.

Sentinel Zeta Prime is the predecessor of Optimus Prime.
Animated series 
In the Transformers: Generation 1 episode "Five Faces of Darkness, Part 4", Zeta Prime, separate from Sentinel Prime, inherited the Matrix of Leadership from Guardian Prime when he was killed during the early days of the war with the Decepticons. His stint as Autobot leader appears to have been a short-lived one, as he died before the end of the war and was succeeded by Sentinel Prime. When Rodimus Prime journeyed into the Matrix in 2005, Zeta Prime was the fifth guide he encountered, who gave a very short account of the continuing Autobot-Decepticon war.
In the Transformers: Prime episode "Alpha/Omega", Megatron and Dreadwing go to the tomb of a dead prime (presumably Sentinel's) and cut off one of his arms, Megatron then has Knockout attach it to him so he can activate that Forge of Solus Prime. When he succeeds in doing so, he turns a piece of Dark Energon in to the Dark Star Saber. With Sentinel's arm, he would use this new sword to destroy the regular Star Saber, wielded by Optimus. He would continue to appear with Sentinel's arm in subsequent episodes until Optimus creates a new Star Saber and cuts of his/Sentinel's arm with it in "Darkest hour".
IDW Publishing 
In the story "Spotlight: Blurr", Zeta Prime, once again separate from Sentinel Prime, was given the unenviable task of solidifying Sentinel Prime's Autobot security forces into a true army to withstand the civil war Cybertron suddenly found itself embroiled in. Towards this end, he locked down most recreational activities, as they were magnets for terrorist activity by the Decepticons. This included a direct order to shut down the races which brought Blurr's stardom. In the wake of these shutdowns, he increased Autobot recruitment heavily, and many former entertainers joined the Autobot forces, only to find they were ill-prepared for the realities of war. Many attempts on his life were hatched, including one which was intercepted by a group of Autobots that included a young soldier named Optimus. Optimus was able to convince Blurr to carry news of the plot to Zeta Prime before the assassins could reach him. Despite this setback, the Decepticons eventually managed to successfully assassinate Zeta Prime. Kup later implied that, like his predecessor, Zeta Prime was killed by Megatron himself.
Sentinel was mentioned in Transformers: Exodus. Here, he bore the sigil of the noble myth of Vector Prime. Also mentioned, he has been attacked at the Altihex Casino with other Autobots. After the battle at the casino, he went missing; Starscream had taken him to a prison and told him to destroy Megatron. In a dark alley, Sentinel met Megatron, who had some other Decepticon gladiators with him. Sentinel was defeated in the ensuing fight, and Megatron retrieved the Code Key of Power.
Video games 
Sentinel (simply called "Zeta Prime" throughout the course of the game) appears Transformers: War for Cybertron. He appears as a boss in the Decepticons campaign, but is defeated by Megatron and the key that activates Omega Supreme is stolen from him. The dying Prime is captured by the Decepticons until Optimus, Bumblebee, and Sideswipe went to rescue him, only to find him being guarded by Soundwave. Sentinel dies after Soundwave steals energy from his lifestream to replenish his own. His body is then brought to the Cybertron High Council, where Optimus is made the next Prime and Autobot Supreme Commander.
