In five films, 48 Decepticons have appeared in the series.
- The Fallen (voiced by Tony Todd), formerly Megatronus, is a rogue Prime of Dynasty of Primes, the founder and the first Decepticon, and Megatron's mentor. In 17,000 B.C., he and his brothers set the Harvester on Earth, but when the humans are discovered the other Primes refuse to activate the Harvester, but the Fallen betrays his brothers, stealing the Matrix of Leadership, the only thing that can turn on the Sun Harvester. Luckily, his brothers stopped him and took the Matrix and hid it from him. Years after his betrayal, he is shown aboard the Nemesis, which was crash landed on one of Saturn's Moons, in some kind of stasis. He is capable of opening Space Bridges at will, and he also has the ability to wield telekinesis, powers restricted to the original Dynasty of Primes. He also wields a metal spear as a melee weapon. During the film, the Fallen seeks to invade Earth with an army of Decepticons and activate the Sun Harvester for an alternative Energon source as well as to get revenge on humanity and the Autobots for his defeat after taking the Matrix of Leadership. Landing on Earth, he uses Earth's telecommunications grid to force the humans to hand over Sam Witwicky, which will lead the Decepticons to the Matrix of Leadership. During the final battle, the Fallen steals the Matrix from a revived Optimus Prime and starts up the Sun Havester, declaring revenge is his at last. However, as the Sun Harvester charges, Jetfire sacrifices himself in order to let Optimus utilize his components. After Rachet and Jolt fuse Optimus with Jetfire's weaponry, Optimus Prime destroys the Sun Harvester and the Fallen is finally killed by Optimus Prime. The writers selected The Fallen after looking through various cartoons and comics for new characters, because he was the most "elemental" villain. At some point, Leonard Nimoy and Frank Welker (the original voice of Megatron) were considered for voicing the Fallen, before Todd came in (who had previously worked with director Michael Bay on The Rock).
- Megatron (voiced by Hugo Weaving in the first three and Frank Welker in the fifth) is the iron fisted, tyrannical, ruthless, and maniacal leader of the Decepticons, Optimus Prime's archenemy, but brother, and an apprentice of his master, The Fallen. Thousands of years ago, Megatron had crash-landed on Earth in the Arctic in his quest to obtain the AllSpark. When he is defrosted, he keeps his original alien jet form out of vanity. Frank Welker, who played the part on television opposite Peter Cullen, auditioned to reprise the role. Bay considered his voice too soft and felt it would be disrespectful to ask Welker to change it. Weaving's voice had been the inspiration Bay gave to his animators for the character, and the character's voice had become that of Weaving in the director's mind. Weaving recorded his lines in Australia, directed by Bay through iChat. The deviation from Megatron's 1980s Walther P38 pistol form was done to avoid morphing. Orci and Kurtzman also felt it would be "the equivalent to Darth Vader [becoming] his own lightsaber and having someone else swing him around". Fans disliked leaked images of the character's head design, so it was redesigned during filming. The prototype design had a much narrower face than the one seen in the finished film. Optimus calls Megatron his brother; Cullen interpreted this line literally, but while the writers state this was the case in early drafts, they consider the line in its final context to be metaphorical. During the final battle in Mission City, Megatron kills Jazz, the Autobot top lieutenant, and duels with Optimus Prime, quickly gaining the upper hand. After being weakened by human fighter jets, Megatron is killed by Sam, who pushes the AllSpark into his spark core, avenging Jazz's death. Later, Megatron's body is dumped into the deepest part of the Laurentian Abyss. In Revenge of the Fallen, Megatron returns. He is revealed to be the apprentice of the Fallen, who is the founder of the Decepticons. Despite Michael Bay's initial claims of him not returning after he was killed and thrown into the Laurentian Abyss in the first film, Megatron is resurrected by the Constructicons with a shard of the AllSpark. Upon being revived, Megatron gains a new alternative mode as a Cybertronian flying tank. He deactivates Optimus Prime and later pursues Sam Witwicky for vengeance and to obtain the AllSpark knowledge the human possess within his mind. In Egypt, Megatron fights a resurrected and upgraded Optimus, but is overpowered and badly damaged, losing the right side of his face and his right arm in the process. Megatron then watches as the Fallen is destroyed. Afterwards, Megatron retreats with Starscream, swearing revenge. When reviving the character, the writers chose not to rename him Galvatron so as to not confuse the general audience. In Dark of the Moon, despite his right arm and his half face repaired at the end of last film, Megatron changes his vehicle mode to an armored rusty Mack Titan 10-wheeler fuel tank truck equipped with heavy weaponry and goes into hiding in Tanzania. After Optimus Prime destroyed half of his face in Revenge of the Fallen, Megatron sometimes hides it by using a cowl. Instead of using a Fusion Cannon integrated into his arm, he wields a hand-held fusion shotgun similar to a Lupara. It is revealed that Megatron made a secret deal with former Autobot leader Sentinel Prime, to invade Earth with an army using Space Bridge pillars and use humanity to rebuild their damaged planet together. However, Megatron is betrayed by Sentinel and has command of the Decepticons taken from him. During the battle in Chicago, Sam's girlfriend Carly goads him back into action; Megatron ambushes and cripples Sentinel. When Cybertron's trip through the Space Bridge fails, Megatron attempts to make a false truce with Optimus, but the latter sees through the ruse and attacks his eternal foe, tearing off Megatron's head with a battle axe. In Age of Extinction, Megatron's head is seen in at KSI, where a captive Brains discovers that the Decepticon leader's consciousness is still alive and in a deep stasis. Megatron's mind silently manipulates Joshua Joyce and his creation of the artificial Transformers, including a Galvatron model where he accepts the name as his new identity and is able to take control of other artificial Transformers as well. Megatron returns in The Last Knight. Concept art for him that has been released has revealed him to resemble a darker, more monstrous version of Optimus Prime's knight form, with a similar faceplate to Optimus's own and a horned helmet vaguely resembling his G1 incarnation helmet. He is further revealed to have his signature forearm-mounted fusion cannon and a knight's sword like Optimus, further emphasizing the enmity between the two. His vehicle mode for the film has been revealed to be a Cybertronian jet, similar to G1 Cyclonus' jet mode. In the film, he searches for the talisman to find Quintessa's staff. Later in the final battle on Cybertron, he is defeated by Optimus when Optimus cuts off his right arm as he did in Revenge of the Fallen, and is kicked through a wall, sending him falling back to Earth.
- Starscream (voiced by Charlie Adler) is Megatron's second-in-command who transforms into a Lockheed Martin F-22 Raptor jet, which is the successor to his original form, the F-15 Eagle. Despite being a popular character, his role is limited because of the film's running time. A post-credits scene of him escaping Earth was added because audiences at test screenings wanted to know what happened to him. This keeps the character's role as the powerful and technologically advanced air commander. Starscream has a rather negative relationship with Megatron. He flew into space at the end of the 2007 film, and returns in Revenge of the Fallen bearing Cybertronian tattoos and symbols on his body and commanding a new Decepticon army (actually gained in the pages of an IDW prequel comic book). Orci explained that it was their intention to let Starscream have more dialogue than in the 2007 film and be more connected to the plot, and that dialogue additions made during post-production edged Starscream closer towards his G1 incarnation. In Dark of the Moon, Starscream is finally killed by Sam Witwicky who blows off his head with a small bomb that was designed and given to him by Que. In The Last Knight, his head was seen being boasted by Daytrader, who claims he found it in Buffalo, New York. Later it is seen being held by Megatron reminiscing about him.
- Blackout is a first-strike Decepticon and the first Transformer appeared who transforms into a MH-53J Pave Low III helicopter. He is extremely loyal to Megatron and uses his blaster in his chest, and the blades. He first appeared attacking the base, and eliminates most of the humans, except Lennox and Epps. He later attacks Mission City where he tries to kill Sam and get the All-Spark. Blackout is killed by human fighter jets and Major Lennox, who shoots him in his spark.
- Scorponok is a Decepticon, a mechanical Scorpion and a minion of Blackout, who is able to dive under sand or other soft surfaces and burrow to attack. In the beginning, he is seen attached on Blackout's back, and during Blackout's attack on Qatar's military base, the former deploys him with Scorponok jumping into the sand. After being damaged by the gunships, Scorponok retreats beneath the sand, and does not appear for the rest of the film, while his tail was recovered by Lennox's team for study. In Revenge of the Fallen Scorponok reappears in the final battle in Egypt, where he disembowels and damages Jetfire, only for Jetfire to crush him under his fist, finally killing him.
- Barricade (voiced by Jess Harnell in the first and fifth, and Frank Welker in the third film) is a Decepticon scout who transforms into a black Saleen S281 police car, whom Frenzy guides to Sam. He is shown as Bumblebee's rival in the first film. He was modeled after the G1 Autobot Prowl, because the writers thought a Decepticon displaying authority would use the police car form. Barricade is able to house Frenzy in a compartment in his chest, ejecting him from his front grill. Takara and Hasbro had designed the flap for his toy and were unaware ILM had taken inspiration from their depiction of the character. Barricade was soon defeated by Bumblebee, but reappeared when Starscream calls the Decepticons to mobilize. Barricade later returned in Dark of the Moon. He appears in the Battle of Chicago last seen being shot in the head by a group of soldiers after a boom-stick blew off one of his legs. Barricade returns in The Last Knight, transforming into a 2016 Ford Mustang police car. Barricade's robot form as revealed in released concept art, has become sleeker and more streamlined than his robot mode in his previous appearances. He also sports an arm-mounted gatling gun on his left arm, and wields a baton and a pistol. Additionally, he possesses brass knuckles with the words "punish" and "enslave" engraved onto them. In the film, he informs Megatron that Cade has a Cybertronian talisman. Later in England, he chases Bumblebee, but is defeated again.
- Frenzy (voiced by Reno Wilson) a small Decepticon spy and a minion of Barricade who transforms into a silver PGX Boombox and later in his head mode, a black Nokia 8800 without his body. He first attacked Sam and pulled off his jeans, but Mikaela tore Frenzy into two with an electric power saw. Later, his body was regenerated from the All-Spark and while attacking a group of humans in the control rooms, Frenzy accidentally kills himself when one of his own shurikens goes full circle and slices his head in two. In Revenge of the Fallen, Frenzy's head is seen in the basement of Simmons' mother's deli.
- Bonecrusher (voiced by Jimmie Wood) is a very hate-fueled and a cantankerous Decepticon who transforms into a Buffalo H Mine-Protected vehicle. The animators modeled his fighting styles on hockey and football players. His alternate form had been chosen based on a promotional image in which the fork looked much bigger than it really was, so for the movie, the vehicle was modified to fit a larger fork. He first appeared when Starscream calls the Decepticons for the location of the AllSpark. He later attacks Optimus on the highway to Mission City, but soon beheaded by Optimus Prime, after his right arm is cut off. In Revenge of the Fallen, аfter reset its remains on the bottom was rebuilt as Megatron, participated in the final battle in Egypt, along with Starscream attacking Arcee and their attacks killed Chromia and Elita 1, when they were trying to protect Sam.
- Brawl is a vicious Decepticon demolition specialist who transforms into an army green M1 Abrams. He has two four-pack rocket-launchers on his back, a harpoon cannon on his left arm and a machine gun on his right arm. During the battle in Mission City, he loses his left arm by Ratchet and was knocked out by soldiers. However, he gets back up and fights. While firing his arm at soldiers, he is finally killed by Bumblebee. For his portrayal, the crew chose to use an Abrams prop built for xXx: State of the Union. After reset its remains on the bottom was recovered as Bonecrusher, was part of the squad that carried out the attack on Chicago, and later was killed by Optimus Prime. This name was intended to be named Brawl (which appears on all the merchandise), but a subtitled Cybertronian line in the film reads "Devastator reporting."
- Soundwave (voiced by Frank Welker) is the Decepticon Communication Officer and one of Megatron's most loyal lieutenants. In Revenge of The Fallen he attaches himself to a military satellite to coordinate the Decepticons' movements around the world. The concept artists also designed an Earth form of a Chevrolet Silverado for him to upgrade into, which was ultimately dropped. The filmmakers had tried to work Soundwave into the 2007 film twice, and these roles eventually evolved into Blackout and Frenzy. The latter character was particularly thought to be too different from the original. In Dark of the Moon, Soundwave now transforms into a silver Mercedes-Benz SLS AMG who poses as a car given to Carly by Dylan. He is later killed by Bumblebee in the battle of Chicago.
- Ravage (vocal effects provided by Frank Welker) is a Decepticon infiltration expert and a minion of Soundwave that resembles a large one-eyed Jaguar and is a fierce hunting machine. He is later killed by Bumblebee in Revenge of the Fallen when Bumblebee rips out his spine during the battle in Egypt. Early in production, he was meant to adopt a fish/submarine-like form right after he first falls into the ocean, and while this was ultimately left out of the movie, it can still be seen in the film's toyline.
- Laserbeak (voiced by Keith Szarabajka) is a Decepticon infiltration expert and a minion of Soundwave that resembles a mechanical condor. Like his predecessor, Ravage, Laserbeak serves as a scout and spy for the Decepticons, and transforms into a Gyrodyne and a variety of electronic devices, such as a desktop computer, and an audio system and even a child size pink version of Bumblebee. He is later killed on a Decepticon ship piloted by Bumblebee during the Battle of Chicago.

- Devastator (voiced by Frank Welker) is a 46 feet (14 m) tall (hunched over) massive robot formed by several combining construction vehicles, who walks in a four-legged fashion resembling a gorilla. He is physically unable to stand up straight. If he did, would be 100 feet (30 m) to 120 feet (37 m). His jaws can open up to form some sort of suction vortex, and he has grappling hooks he is seen using to climb a pyramid. A Combiner, Devastator is the Decepticons' ultimate weapon. He is destroyed by a prototype railgun during the battle in Egypt. The 9 combined vehicles of Devastator are Scavenger, Overload, Mixmaster, Scrapper, Hightower, Long Haul, Rampage, Skipjack, and Payload.
- Demolishor (voiced by Calvin Whimmer) is a large Constructicon who transforms into a white with red stripes Terex O&K RH 400 hydraulic mining excavator. In robot mode, his treads turn into huge wheels, enabling him to roll either on the two of them, or only on the front one, with the rear lifted behind his head. He is killed when Optimus Prime shoots him in the right eye at point blank range.
- Rampage (voiced by Kevin Michael Richardson) is a Constructicon who transforms into a red Caterpillar D11T bulldozer with model number M930, while in the toyline, he is a yellow Caterpillar D9L bulldozer, whose Robot mode is based after the Beast Wars incarnation of the Same name. His robot mode resembles an upright-standing snake with his treads coming out of his hands, which he uses as whips. He is later killed by Bumblebee. In the film, he is credited as Skipjack.
- Mixmaster is a Constructicon who transforms into a black and silver Mack concrete mixer truck. He is briefly seen to have a third "battle mode" which appears to be a gun emplacement. According to his toy bio, he is an expert in chemistry and explosives who makes explosives and poisons for the other Decepticons' weapons. Some of the concept art shows him as a McNeilus mixer truck. He is killed by Jetfire.
- Long Haul is a Constructicon who transforms into a green Caterpillar 773B dump truck. Long Haul's robot mode was designed by freelance artist Josh Nizzi as fan art of the original character, by the time Revenge of the Fallen had just been greenlit. The fan art impressed Bay enough to hire him on to the film. After the air strike in Egypt from long Haul escaped only his head became a drone Igor. Although in the movie Long Haul's alt mode is a Caterpiller 773B, a relatively small truck, Nizzi had originally meant Long Haul to be a Caterpillar 797, one of the largest dump trucks in the world.
- Scrapper is a Constructicon who transforms into a yellow Caterpillar 992G scoop loader. He is seen to be able to use his left arm as a chain mace. Survived an air strike in Egypt, was part of the squad that carried out the attack on Chicago, and later was killed by Optimus Prime.
- Scavenger is a large Constructicon who shares the same model of Demolishor. Red excavator Terex O&K RH 400. He appeared in the final battle of Egypt, where he and the Constructicons form Devastator, but soon killed by a prototype railgun, alongside the Constructicons.
- Overload is a Constructicon who transformed into a red Komatsu HD465-7 Tractor Truck articulated dump truck. Armed with hooks and pincers, like a crab.

- Reedman (voiced by Frank Welker) is a one-eyed razor-thin robot. Reedman appears when at a certain point in the film, Ravage is seen deploying a load of marble-sized "microcons" that adopt an intermediate bug-like robot form, and end up grouping together to form Reedman. Reedman's extremely thin frame serves him as his main ability, by making him virtually invisible as long as he is facing directly at his enemy.
- The Doctor (voiced by John Di Crosta) is a small spider-like medic and scientist equipped with tools who transforms into a microscope. He first appeared deployed from Ravage to revive Megatron. He is seen again, used to extract information from Sam Witwicky In Dark of the Moon, similar looking Deceptions are seen crawling over and repairing Megatron's damaged head.

- Shockwave (voiced by Frank Welker) is a Decepticon scientist. He is killed in the Battle of Chicago by Optimus. Shockwave transforms into a Cybertronian self-propelled artillery vehicle. Like his original G1 appearance, Shockwave's head features a single red eye, and has a gun in place of one of his hands, with a tube connecting it to his back. Visual effects supervisor Scott Farrar said that the lack of eyes and mouth in Shockwave's design means "you have to read Shockwave through just the emotions of his face, almost like a silent-era film star," which caused the eye to have an intrinsic design, with a lens, a moving iris and an oscillating light.
- The Driller is Shockwave's pet; a giant, tentacled Mongolian death worm-like Cybertronian creature, which is used for drilling purposes. It is also Cybertron's most feared predator. The Driller appeared, attacking and killing NEST soldiers, tried to get the engine part of the Ark, but Optimus stops it and retreats.

- Watch-bot - A small scorpion-like Decepticon spy who transforms into a wristwatch in Dark of the Moon used by Dylan Gould before it was killed by Sam Witwicky.
- The KSI Drones are the human-made Transformers that were commissioned by Attinger and built by KSI. They have the ability to change their forms molecularly instead of just transforming. They were built with the metal extracted from the remains of the dead Transformers. They also modeled after both Autobots and Decepticons. They were originally mindless drones remote-controlled by humans, but later were granted autonomy by the Megatron possessed Galvatron, organizing them into a new Decepticon army. They fought in the battle of Hong Kong but were soon destroyed by the Autobots, Cade Yeager and the Dinobots. According to Joshua Joyce, KSI made about fifty molecularly transforming robot prototypes.
- Galvatron (voiced by Frank Welker) is a KSI prototype modeled after Optimus Prime, but corrupted and possessed by Megatron in Age of Extinction. In the film, Megatron's mind silently manipulates Joshua Joyce and his creation of the artificial Transformers. Upon learning of Harold Attinger's deal with Lockdown for the human to obtain a Seed, a cyberforming bomb, he plots to use it to destroy a human city and rebuild the Decepticon army. Galvatron is first deployed to catch Optimus Prime. The two fight, but Galvatron withdraws on Joshua's orders after Lockdown unexpectedly arrives. During the battle, however, Galvatron shows several signs of independence; he destroys several civilian cars, fires missiles unbidden and even talks, something that he was never programmed to do. Galvatron later takes control of the KSI drones and uses them as his minions in an attempt to retrieve the Seed. His army is soon destroyed along. However, Galvatron survives vowing that he will meet Optimus again, and declares that he is reborn. Galvatron transforms into a black and grey 2014 Freightliner Argosy cab over truck and he shares the ability of other KSI creations to change his form molecularly instead of just transforming.
- Stinger is a KSI prototype modeled after Bumblebee, who later becomes a Decepticon and transforms into a red and black 2013 Pagani Huayra. He is later killed after having his head blown off by Bumblebee and eaten by Strafe. His role in Galvatron's army appears to be the sabotage specialist.
- Junkheap is a KSI prototype who later becomes a Decepticon and transforms into a green Isuzu Giga garbage truck of Waste Management, Inc. He has the ability to split into three different drones that share the same single consciousness at will. They were killed by Hound and Optimus Prime. A Junkheap made a cameo in age of extinction

He was selected by Megatron after rejecting Berserker, who was too violent, dangerous, and out of control. He dies after losing his right leg and being beheaded by Drift.
- Dreadbot is a Decepticon thug and a bank robber who shares the same body of Crowbar and transforms into a rusty Volkswagen Type 2 with Christmas lights in his right arm. His TRF description states that he is IN CUSTODY, and that he owns a unique Cybertronian firearm. He is soon eaten and killed by Grimlock.
- Mohawk (voiced by Reno Wilson) is a loyal Decepticon footsoldier who transforms into a Confederate Motorcycle. His TRF description states that he is IN CUSTODY, and that he is skilled with knives.

William Lennox (portrayed by Josh Duhamel) is an Army Rangers officer, who in the first three films as an eight-man Joint Special Operations Command team in Qatar, who survive Blackout's attack on the base. Lennox has a wife and newborn daughter in the United States. Duhamel was a fan of the toy line as a child, and with Tyrese Gibson, they spent three days in boot camp to prepare for the role.
In the first film, Lennox is Army Rangers Captain, to help Sam Witwicky and Mikaela Banes with the Autobots.
In the second film, he is promoted to Major, and is now part of NEST, an international taskforce battling Decepticons with the Autobots.
Lennox returned in The Last Knight as a former TRF member who dislikes Santos for killing Autobots.
|Portrayed by||Tyrese Gibson|
|Occupation||Ally to the Autobots|
Robert Epps (portrayed by Tyrese Gibson) is a United States Air Force Combat Controller Technical Sergeant. Duhamel and Gibson were fans of the toy line as children, and Gibson paid the filmmakers so he could be in the film. Gibson spent time learning technical terms and military code from an actual combat controller to make his dialogue sound convincing.
In the first film, he is an Airman and friend of Lennox, and combat controller in the US Air Force. When fighting alongside the Autobots with Sam Witwicky and Mikaela Banes.
In the second film, Epps is promoted to USAF Master Sergeant, a Combat Controller and a member of NEST. He was given different first names in merchandise, like Ray Epps in The Last Prime storybook, and Julius Epps in The Movie Universe book.
In the third film, Epps left NEST and retired from the U.S. Air Force. He is seen helping the Wreckers with repairs to the Autobot ship Xantium and he also joined the final fight and to help Sam Witwicky catch Dylan Gould, because, he says, "the Autobots were [Epps]' friends too". Epps and Lennox appear at the end to learn that Dylan is already dead by Sam.
He was supposed to return in The Last Knight, but due to Gibson having scheduling conflicts with The Fate of the Furious, he didn't appear.

Samuel James "Sam" Witwicky (portrayed by Shia LaBeouf) is the main human protagonist of the first three films. In early versions of the script, Sam had the nickname "Spike" (the name of the main character in the original Transformers series). This idea was later scrapped because, according to writer Roberto Orci, these nicknames were appropriate for a mechanic and an oil rig worker in the animated series, occupations in which the characters did not work in the film. According to Roberto Orci, the character of Sam was written as a "2007 version of Marty McFly". Sam Witwicky did not return for the fourth film; his character is later replaced by Cade Yeager (portrayed by Mark Wahlberg). LaBeouf makes a brief cameo as Witwicky in a photograph in Burton's mansion in Transformers: The Last Knight.
Sam appears in Transformers: Tales of the Fallen #1 by IDW Publishing. Barricade kidnaps Sam in order to flush out Bumblebee and learn where the All Spark fragment is. Bumblebee saves Sam by fighting and defeating Barricade. However Barricade eventually escapes.
The drone calling itself Brains runs into Bumblebee and Sam Witwicky in Philadelphia.
Sam appears in the book Transformers: Dark of the Moon: The Junior Novel.
In Transformers, Sam Witwicky was a social outcast who unintentionally buys Bumblebee as his first car. Sam is at first unaware of his car being a Transformer, despite the fact that Bumblebee was responsible for helping Sam to (somewhat) get close to his crush, Mikaela Banes. During the first night, Bumblebee leaves the house, which caused Sam to follow believing his car had been stolen. Later that night, he becomes surprised to find that his car became a robot. After being saved from Barricade by Bumblebee, Sam learns the full story as he helps the Autobots by keeping the AllSpark away from the Decepticons until he uses it to kill Megatron.
In Transformers: Revenge of the Fallen, Sam is going to college and is trying to have a normal life and get away from the world savior status. But while getting ready, Sam finds a sliver of the AllSpark on his jacket which gives him visions, causing him to suffer a mental breakdown as a result. Optimus turns to him for help in convincing the human government to allow the Autobots to stay. Sam refuses, saying he wants a normal life and Optimus doesn't need him anymore to which Optimus replies that they need Sam more than he knows. One of the girls in Sam's dorm who apparently likes him, Alice, turns out to be a Decepticon Pretender who attacks him by lying down on him. Sam is saved by Mikaela, who kills Alice. Sam is then later abducted by Decepticons to acquire the information in Sam's mind before Megatron can vent out his aggression on the boy. Megatron makes Sam lie down on a table before having Scalpel remove his brain. But after being saved by Optimus, who is killed during the fight, Sam ends up leading Mikaela, Bumblebee, his roommate Leo, the Twins: Skids and Mudflap, and Simmons in a quest to find the Matrix and use it to revive Optimus. During the final battle, Sam is killed by Megatron until he was revived by the Dynasty of Primes so he can resurrect Optimus, allowing him (Optimus) to kill the Fallen and save Earth. With Earth saved once more, Sam finally admits he loves Mikaela. On an aircraft carrier later, he and Optimus thank each other, Optimus thanking Sam for saving his life and Sam for Optimus believing in him.
In Transformers: Dark of the Moon, his final appearance, Sam has been dumped by Mikaela and has a new girlfriend named Carly Spencer whom he met after being given a Presidential Medal of Freedom by the President Barack Obama for his heroic accomplishments in the past. Sam now lives with Carly Spencer, a pet dog and former Decepticon Wheelie, and his partner, Brains. Bumblebee no longer lives with him, working with the other Autobots on secret missions, forcing Sam to drive a rundown car that vaguely resembles a small Bumblebee. Sam ends up finding a job as a mail boy despite wanting to work with the Autobots, but is dragged back into the war by Decepticon collaborator Jerry Wang and Laserbeak. Sam, with the help of Simmons, figures out the Decepticons' plot and is forced by Dylan Gould into finding out the Autobots' plans for the Decepticons. Sam is devastated when the Autobots are exiled from the planet and then apparently destroyed and teams up with Epps and other former NEST soldiers to rescue Carly from Chicago. He later sees the Autobots returned after faking their death. Sam succeeds with help from Bumblebee and in the battle that follows, he kills Starscream and Dylan Gould who retriggers the space bridge after Optimus stops it. Sam reunites with Carly after the Decepticons are defeated and admits he loves her. Sam Witwicky is never seen again after Dark of the Moon, and his fate is ultimately unknown.
In The Last Knight, a photo of Sam is seen as part of the Witwiccan Order gallery along with Sir Edmund Burton (played by veteran actor Anthony Hopkins), who is the last surviving member of the "Witwiccan Order". However, due to Burton being the last surviving member, it can be implied that Sam may be dead at this point.
- Transformers Deluxe Barricade with Frenzy Screen Battles: First Encounter (2007)
- A mini-diorama gift set with Barricade and figurines of Sam and Mikaela, along with an extra, non-poseable Frenzy figure.
- The original "radiator" Frenzy available with Screen Battles: First Encounter Barricade was remolded in black (matching the car) but was installed with additional piece of plastic, preventing the black Frenzy figure from being removed -- due to redundancy -- without unscrewing the base of the Barricade's hood. This version of Frenzy has been referred to as "Restrictor Plate Frenzy" by collectors.
- Revenge of the Fallen Human Alliance Bumblebee with Sam Witwicky (2009)
- A larger (between Voyager Class and Leader Class size) figure than the Deluxe Class figure with a 2-inch-tall figure of Sam, which can ride inside Bumblebee.
- Transformers Human Alliance Bumblebee with Sam Witwicky (2010)

In the first two Transformers films, Mikaela Banes (portrayed by Megan Fox) is Sam Witwicky's first love interest. Differentiated from "typical" women in her age group, she has inherited mechanical skills from her father, Cal, a grease monkey and paroled car thief.
Mikaela was present shortly after the battle at Mission City in Transformers: Alliance #1 (December 2008) by IDW Publishing.
In Transformers, Mikaela is initially the girlfriend of football player Trent DeMarco; however, she soon ditches him because of his snobbish attitude and because he treats her like a trophy wife. Sam offers her a ride home, as he has a crush on her, and Mikaela accepts Sam's offer. She inspects Sam's broken-down 1976 Chevrolet Camaro (nicknamed Bumblebee) in an empty lovers lane and is astonished at the various modifications present in the engine bay. Unfortunately, the visuals of the actual engine under the hood show a continuity error on the part of the filmmakers: the shot shows that Bumblebee has a Kinsler crossram fuel injection intake manifold, but her character discusses a double-pumper carburetor. She also surprises Sam with her knowledge about cars which he finds more attractive than the popular shallow girl she acts like around others. When asked why she keeps her mechanical expertise a secret, she says, "guys don't like it when you know more about cars than they do." Mikaela criticizes the poor conditions of Bumblebee's vehicle mode, causing him to scan a passing 2007 Camaro Concept and transform into the same model. She fights in the Battle of Mission City, initially pulling the seriously injured Bumblebee out of battle, but is ultimately unable to leave them to fight alone. She tells Bumblebee that if he's willing to fight, she'll take him back in and navigate. He acquiesces and with her help, Bumblebee rejoins the battle and destroys Brawl. After the battle, she and Sam begin dating because when they meet the Autobots, Ratchet said that he knows Sam has a crush on Mikaela and tells everyone.
Mikaela returns in the 2009 sequel Transformers: Revenge of the Fallen, carrying on a long-distance relationship with Sam. As he goes off to college, Sam entrusts her with a fragment of the AllSpark, which he found in the jacket he was wearing when he killed Megatron. Mikaela hides the fragment in a safe at her father's motorcycle repair shop, but she is followed by the Decepticon spy Wheelie, who is intent on recovering the fragment. She catches the spy and interrogates him. After going to inform Sam, Mikaela saves him from the Decepticon Pretender Alice (whom she kills and also found kissing Sam), only to be captured by Grindor and taken to the recently repaired Megatron. Rescued by Optimus Prime, Mikaela and everyone escape, and on the recommendation of Sam's roommate Leo, they seek help from a man who runs a robot conspiracy website. He is later revealed to be Agent Simmons. Simmons and Wheelie lead them to Jetfire, who uses a Space Bridge to transport the group to Egypt, where the Autobots and their allies battle the Decepticons and The Fallen. She is devastated when Sam apparently dies, but is ecstatic when he is revived and finally tells her he loves her. She survives the battle and returns home. Seen in the credits Sam kisses Mikaela goodbye as he returns to college.
Mikaela does not appear in the 2011 sequel Transformers: Dark of the Moon nor any of the other films due to Megan Fox being fired. Because of this, the film's storyline says that Sam and Mikaela broke up and went their separate ways.
