Query: Who are the opposites of the Autobots?
Autobots are a team of sentient mechanical self-configuring modular robotic lifeforms from the planet Cybertron led by Optimus Prime, and the main protagonists in the universe of the Transformers, a collection of various toys, cartoons, movies, graphic novels, and paperback books first introduced in 1984. The "Heroic Autobots" are opposed by the Evil Decepticons.[1][2][3] Both Autobots and Decepticons are humanoid robots that can transform into machines, vehicles and other familiar mechanical objects, as well as mimic organic lifeforms (Dinobots). Autobots typically transform into regular cars, trucks, or other road vehicles (auto</i>mobiles) but some few are aircraft, military vehicles, communication devices, weapons, and even robotic animals. These Autobots are often grouped into special "teams" that have the suffix "-bot" at the end, such as in Dino<i data-parsoid='{"dsr":[2847,2854,2,2]}'>bot (Decepticon groups' names end in "-con").
The Autobots are the main protagonists of the series. Many Autobots on Cybertron are employed with a military force called the Autobot Elite Guard, with the main leader holding the title of "Magnus" and high-ranking lieutenants holding the title of "Prime". The main cast of Autobots in the series are a team of low-ranking maintenance workers led by Optimus Prime, who discover the Allspark (the legendary source of all life on Cybertron) hidden on an asteroid. The majority of Autobots in Transformers: Animated transform into non-military terrestrial vehicles and carry non-projectile weaponry such as swords, shields, shurikens, stingers, nunchucks, axes, etc. Many Autobots in this series do not possess the capability of flight, except for Jetfire and Jetstorm, their combined form Safeguard, Omega Supreme and all other Omega Sentinels, Optimus Prime, Bumblebee, Prowl, Swoop, and Sari among others.
The Dinobots are three Transformers that transform into mechanical dinosaurs. They were originally animatronic dinosaur props at a theme park, but were accidentally brought to life and given the ability to transform by Sari's Allspark key. They were also tricked by Megatron into hating the Autobots. The Dinobots rarely become involved in the conflict between the Autobots and Decepticons, preferring instead to live peacefully on a remote island. If the planned fourth season would have been made, the Dinobots would have most likely side with the Autobots in the finale "Megatron Must be Destroyed!".A group of Autobots named for the headquarters of the Autobots in "."The series also features many cameo appearances from several classic Autobots from the Generation 1 toy-line and television series where they were featured in crowd appearances. Some of their names and purposes were revealed in the "Allspark Almanac II". Among the Autobot cameos are:The Decepticons are the primary antagonists of the series. Despite being a military force, unlike the Autobot Elite Guard they have no clear hierarchy, Megatron is the sole leader and every other Decepticon is his inferior. The majority of Decepticons transform into military vehicles, mainly aircraft, and carry projectile weaponry such as guns, cannons and missile launchers. The Decepticons in this series are shown to be bigger, stronger, and more powerful than the Autobots. It takes a group of Autobots to defeat one lone Decepticon, but Optimus Prime is the first Autobot shown to defeat Megatron alone.
After Autobot leader Optimus Prime and Decepticon leader Megatron disappeared in a Space Bridge accident several million years ago, the Autobots and Decepticons split up into several factions. One of those who broke away was Ratbat, who quickly took the opportunity to form his own power base. Gathering loyalist followers and setting up their HQ in the Polyhex region of Cybertron, the Ultracons quickly came into conflict with the Autobot splinter faction The Wreckers. However, Ratbat added a secret weapon to his ranks – the combiner team the Constructicons, in flagrant defiance of treaties banning their use in the civil war as both Autobots and Decepticons splintered.
Sunstreaker is the split-spark twin brother of Sideswipe. Before the civil war between the Autobots and the Decepticons, Sunstreaker was an artist. After the war broke out he joined the Autobots, but some who knew his violent disposition joked that he didn't join the Decepticons simply because their purple logo clashed with his paint job. When Decepticon leader Megatron and Autobot leader Optimus Prime temporarily disappeared in an accident with a space bridge, the Autobot and Decepticon forces splintered into smaller factions. Sunstreaker stayed with the Autobots under the leadership of Prowl and battled the Fallen when he attacked the Autobot base.
When civil war broke out on the planet Cybertron between the Autobots and Decepticon factions, Jazz joined the Autobot cause. After Decepticon leader Megatron killed the Autobot leader Sentinel Prime, a new Autobot leader was chosen by the Council of the Ancients. Jazz was present when Optronix was given the Matrix and reformatted into Optimus Prime. Three Decepticon assassins attempted to kill Optimus, but were unsuccessful. Optimus then ordered a planet-wide evacuation of Cybertron ("" #1). When Shockwave led a force of Decepticons against the Autobot capitol of Iacon, Jazz was among the Autobots who defended the capitol ("War Within" #3).
The war between the Autobots and Decepticons soon caused Cybertron to break away from its orbit and drift off into space, and the war was listed as raging on for over one thousand years. Eventually, Optimus would lead a large team of Autobots on a space mission to clear asteroids that threatened to destroy Cybertron on its new course through space. But, once they succeeded in this effort, a surprise attack by the Decepticons led their spacecraft (the Ark) to crash land on Earth, where it would reside for four million years in a dormant volcano. Eventually, when the volcano erupted, it set off a chain of events that would revive the Autobots and Decepticons who had all been deactivated in the crash. Through the comic's 80-issue run, Optimus Prime would be killed off and resurrected several times. During his absences, other Autobot officers took on the mantle of leadership within the Earth-bound Autobots. They included Prowl, Grimlock, Fortress Maximus, and others. In a future timeline (one that, per events in the "present", can no longer come to pass), the Autobots are commanded by Rodimus Prime.
Ironhide appears in the story arc "Beast Wars Shattered Glass" by Fun Publications. Ultra Magnus and his Autobots discover that their ship's high security storage rooms were damaged in the crash and the Autobot bodies in stasis pods were lost. They head out to recover the pods when they are attacked by Dirge and Seawing. They find the pods, but also discover that Megatron has gotten to them first. He's converted the three Autobots into Autojetter, Autolauncher, and Scylla, who are loyal to him. The Decepticons attack the Autobots, who are only saved thanks to the intervention of Depth Charge. Ultra Magnus orders the retreat, as there is nothing left for them to recover. Depth Charge informs the Autobots of his mission to save the multiverse.
When Brainstorm needed subjects to duplicate a Decepticon Pretender experiment, Cloudburst and five other Autobots volunteered and became the Autobot Pretenders. They fought the Decepticon Pretenders with the help of Optimus Prime and Goldbug (Transformers #40). They soundly defeated their Decepticon Pretender rivals, who thought they were simply giant humans. Cloudburst was present when Grimlock fought Blaster for leadership of the Autobots on Earth's moon. The Autobots were then attacked by the Decepticons led by Ratbat (Transformers #41).
This is a list of known Autobots in the Transformers fictional universe and toy line. The alternate modes of Autobots are usually cars, trucks, and various other ground-based civilian vehicles, to contrast with the military vehicles favored by the Decepticons (see List of Decepticons). One of the most notable Autobots is B-Skaf, who could turn a van into a train."Powerdashers are mail order Transformers whose name stood for one of three available molds."
Fleeing the wars that devastated their home planet of Cybertron, most of the Autobots made Earth their temporary home. Under the leadership of the powerful robot, Optimus Prime, the heroic Autobots battled fearlessly against the assaults of the evil Decepticons, protecting their new human friends. Now it is the year 2006, and the Autobots have reclaimed the planet of their origin, Cybertron, to establish a new Golden Age. In migrating from Earth, they have been reunited with companions from other regions of the galaxy, including Sky Lynx, the gigantic space shuttle, Blurr, the fastest car on wheels, Kup, the flinty old warrior, Wheelie, who always offers advice in rhymes, Springer, the mighty helicopter, Arcee, a forceful female Autobot, and Wreck-Gar, the leader of a tribe of Autobots that dwells on the planet Junkion. The Autobots have a new leader, Rodimus Prime, who inherited from Optimus Prime the Autobot Matrix of Leadership. As a receptacle of the wisdom of Autobot leaders for the past millions of years, the Matrix helps Rodimus guide the Autobots in their darkest hours, as they fight to end the tyranny of the evil Decepticons.
When civil war broke out between the Autobots and Decepticon factions, Trailbreaker joined the Autobot cause. He was in command of Grimlock at the battle of Altihex, where the Autobot Overhaul was killed and Decepticon seekers Thundercracker and Skywarp destroyed a transport full of neutral Cybertronians. Unable to save the city, the Autobots helped evacuate civilians ("" #1). When Shockwave led a force of Decepticons against the Autobot capital of Iacon, Trailbreaker was among the Autobots who defended the city ("War Within" #5-6).
The word "Autobot", according to Ratchet, is an abbreviation of the phrase Auto</b>nomous ro<b data-parsoid='{"dsr":[38012,38021,3,3]}'>bot</b>ic organisms, making it seem like Autobot is likely the Transformers species name in this continuity (the irony being that the term robot is derived from the Czech word "robota" for "work" and thus expresses the opposite of autonomy).
Sky Lynx first appeared after Grimlock had taken up leadership of the Autobots after Optimus Prime's death. He sided with the "rebel" Autobots Blaster and Bumblebee who Grimlock, leader of the Autobots at the time, thought were criminals.
During Autobot training, his double-agent status was almost discovered by Bumblebee. But thanks to Bumblebee believing the spy to be Wasp, Shockwave managed to plant the evidence to have Wasp as his scapegoat. After successfully graduating from training, Longarm is eventually promoted to Prime rank, and made intel commander of Cybertron, allowing him full access to Autobot files, which he passes onto Megatron, who has him ensure Cybertron is left helpless as part of his master plan. In the two-part "A Bridge Too Close" episode, Shockwave informs Megatron that the Autobot who got the highest scores in the Space Bridge aptitude test is Bulkhead, leading Megatron to capture the Autobot. When the rest of the earth Autobots try to rescue Bulkhead, they are captured themselves, and Shockwave appears on a screen to taunt Bumblebee with the truth of his double agent status, and the fact that he had an innocent Autobot (Wasp) imprisoned (this later led to Wasp becoming Waspinator).
In the Shattered Glass storyline, a group of Autobots, led by Optimus Prime, are the mirror images of the personalities of most Autobots. In this world the Autobot logo is purple, and worn by evil Transformers who seek to destroy the universe, and are opposed to the heroic Decepticons.
At that point, Cybertron was believed to be dying as a result of the battle with Unicron, and the Autobots and Decepticons were co-operating to evacuate. However, the Decepticons had a hidden motive: to escape, and leave the Autobots marooned on the dying planet. Grimlock and the Dinobots were the only ones among the Autobots who saw through the Decepticons' false pretense of peaceful co-existence and suspected the plan of mass betrayal. When the Decepticons sabotaged the Autobots' ships and fled the planet, Grimlock saved the Autobots. He revealed that he had captured Decepticon ships after a strike against them before the voyage to Earth, and had hidden them away. Thanks to those ships, the Autobots were able to flee Cybertron and follow the Decepticons to the planet Klo for a final showdown. Unfortunately Decepticon leader Bludgeon had discovered the Autobot homing beacon and laid a trap for them. Grimlock's stubbornness meant the Autobots walked right into it, decimating them. Grimlock was one of the few survivors, and when Optimus Prime returned, recreated by the Last Autobot, Grimlock participated in the rout of the Decepticons.
In Transformers: Prime, with Cybertron dead, the Autobots scattered across the universe. A group landed on Earth consisting of Optimus Prime, Ratchet, Bumblebee, and Bulkhead and which Arcee and Cliffjumper join later. This small team of Autobots led by Optimus is rechristened Team Prime. By the time of the first episode has been three years since the Decepticons last attacked Earth and the Autobots still await their return. Starscream kills Cliffjumper. After the death of Cliffjumper, the Autobots fight to protect the Earth from the Decepticons and befriend three young humans and the returned Megatron who has been missing for three Earth years. Megatron plans to use Dark Energon to raise an undead army of Cybertronians and defeat the Autobots. The Autobots destroy his space bridge and Megatron is believed killed in the process. Starscream becomes the new Decepticon leader.
When civil war broke out on the planet Cybertron between the Autobots and Decepticons, Cliffjumper joined the Autobot cause.
When Decepticon Military Operations Commander Shockwave led a force of Decepticons against the Autobot capitol of Iacon, Cliffjumper was among the Autobots who defended the capitol (Transformers: War Within #3).
The third season began on March 14, 2009 with the three-part premiere, "Transwarped", and ended on May 23, 2009. This season following the events of "Transwarped" focused on the Autobots' attempt to reach Cybertron in order to warn the Autobot High Council of Shockwave, who has been masquerading as Autobot Intelligence Officer Longarm Prime. Meanwhile, Megatron, Starscream, Shockwave (who replaces Blitzwing as a main character), and Lugnut plan to use the colossal Autobot Omega Supreme for constructing clones of him (dubbed as Lugnut Supremes, as they appear similar to Lugnut).
After Autobot leader Optimus Prime and Decepticon leader Megatron disappeared in a Space Bridge accident several million years ago, the Autobots and Decepticons split up into several factions. One of those who broke away was Ratbat, who quickly took the opportunity to form his own power base. Gathering loyalist followers and setting up their HQ in the Polyhex region of Cybertron the Ultracons quickly came into conflict with the Autobot splinter faction The Wreckers. However, Ratbat added a secret weapon to his ranks - the combiner team the Constructicons, in flagrant defiance of treaties banning their use in the civil war as both Autobots and Decepticons splintered.
Meanwhile, back on Earth, with their members running low on energon and slowly being captured by Skywatch, tension is high amongst the Autobots. After a rescue raid led by Hot Rod results in Ironhide's death, Optimus Prime gives up his position as leader and surrenders to Skywatch, causing a schism between the Autobots, who split into two groups: one led by Hot Rod, who, taking the name "Rodimus", joins forces with a group of Decepticons fronted by Swindle in an effort to build a ship and leave the planet, and a second who elect Bumblebee as their new leader, and are soon joined by Ultra Magnus, who determines to arrest Rodimus for treason. More Autobots, fearing they will be arrested by Magnus, also go AWOL, but most of them are captured by Skywatch and used as a bargaining tool by Spike Witwicky to force information out of Optimus Prime. Thundercracker, having been shot down by Skywarp three years previously, starts to develop admiration for Earth and its inhabitants. Although Bumblebee was elected as Autobot leader, he gets little respect, as Autobots strike out on their own or disrespect his authority. A rogue faction within Skywatch contacts the Autobots and sets up a meeting with Bumblebee to enlist the Autobots' help in capturing Decepticons. Bumblebee agrees and the bots are fitted with special badges to cloak them from the main Skywatch force, but when the Colonel orders the capture of Blurr and resentment ensues, the Autobots learn that the badges also have the ability to immobilize them. Meanwhile, Magnus arrives at Hot Rod's camp and attempts to capture Swindle, but is stopped by Hot Rod. He also fails in trying to get Hot Rod to disassemble the ship his party is building to get off Earth. In the battle that follows, Swindle betrays Rodimus and reveals his new creation, Menasor, but the day is saved thanks to Skywatch, with whom Optimus Prime has brokered an alliance, and some timely side-switching from the disillusioned Thundercracker. The disgraced Rodimus flees Earth alone, and the Autobots rally under Bumblebee.
Circuit Breaker leads a giant Autobot she created from parts of other Autobots against the Decepticon Battlechargers in Marvel's Transformers comics. Circuit Breaker then captured Autobots Air Raid, Fireflight, Silverbolt, Skids, Skydive and Slingshot. Using the parts from all the captured Autobots she created a giant Autobot with herself in control, striking a deal with them that if they would cooperate she would let them go. Circuit Breaker then used them to attack the Decepticon Battlechargers Runabout and Runamuck who were attacking the Statue of Liberty. After defeating the Decepticons with Circuit Breaker the Autobots were released ("Transformers" #23).
With the Autobot Headmasters captured by their Decepticon counterparts, the Decepticons ran rampant over the planet Nebulos, a group of the remaining Autobots on the planet joined with a group of Nebulons branded as criminals by Nebulon's political leader, Lord Zarak - partner of the Decepticon, Scorponok - in order to protect the Nursery, Nebulos's primary agricultural research facility, against Decepticon attack. Through bio-mechanical engineering, the Nebulons were given the ability to transform into the guns of the Autobots, and, as Targetmasters, they fended the Decepticons off. Within several days, the Decepticons had duplicated the process with five of their own troops. Then, realising how much damage his actions were causing Nebulos, Zarak freed the Autobot Headmasters, who fled the planet, and were pursued by the Decepticons, leaving Nebulos to recover from the brief war. The Autobots, including the Targetmasters, then traveled to Earth, where they became part of the main Autobot force.
The Decepticon Targetmasters overcame the Autobots and reclaimed the key to the Plasma Energy Chamber, but in the struggle, the Autobot Brainstorm was able to scan Cyclonus's partner, Nightstick, and that data was used to duplicate the Targetmaster process with the remaining Autobots and Nebulan rebels, creating the Autobot Targetmasters. Their power, however, was nothing in the face of the Decepticons' newest weapon, the super robot, Scorponok, who transported the Decepticon forces back to Cybertron, where their plans were foiled by Spike Witwicky and Fortress Maximus.
Landing in Alaska, Jazz and the other Autobots met Prowl's team back from Cybertron. They were shown the site of construction for the new Autobot City ("Transformers: Generation One" vol. III #10). Brawn, Grapple, Hoist, Jazz, Omega Supreme, Prowl, Red Alert, Sideswipe and Sunstreaker were among the Autobots who continued work on Autobot City ("Transformers: Generation One" vol. III #13).
