Sunstreaker (G1)
Sunstreaker is an Autobot in the Generation 1 continuity.
Sunstreaker knows that he is better than any Autobot. His polish is worth more than all the Minibots put together. It's not that he's a sociopath, it's just that other beings simply don't matter to him. Well, okay, he's a sociopath.
The only Autobot who he gets along with is his brother Sideswipe. Primus knows why Sunstreaker is on their side. Optimus Prime only keeps him around because he's so effective on the battlefield. Sunstreaker is ruthless.
Marvel Comics Continuity
Prior to the outbreak of Cybertron's planet-wide civil war, Sunstreaker was a gladiator in the State Games.
Early into the Autobot-Decepticon war, Sunstreaker was a member of the Magnificent Six. With them, he was involved in a mission to the Stanix region of Cybertron that would end in tragedy.
Sunstreaker was among the crew of the Ark that crashed 4 million years ago and woke up in 1984.
In the first few days on Earth, Sunstreaker diverted an attack by Thundercracker and Skywarp towards a human civilization so as to keep himself from harm.
When Shockwave took control over the Decepticons and possession of the Ark, he destroyed Sunstreaker's body as a demonstration and warning to the deposed Megatron. Because of this, Sunstreaker's body was in disrepair for a very long time.
Several Autobots, including Sunstreaker, who were shut down in the medical bay were woken up by Galvatron's Dream-Inducing Bug. Galvatron had planned to use the dreams of the dead to aid him in his conquest, but after a short skirmish, Galvatron's device was placed on himself.
Sunstreaker was fully repaired in time to view the duel between Blaster and Grimlock on the moon.
Later, Sunstreaker was sent on a new mission to the Stanix region of Cybertron with Silverbolt, Ironhide, Wheeljack, Jazz, and Inferno by Optimus Prime. While there, he overcame the ghosts of the past and helped defeat the mad Decepticon Megadeath.
Following this, Sunstreaker was hurt in an undisclosed incident and was revived by Nucleon on the Ark. He and the other newly revived Autobots joined the attack on Unicron.
Animated Continuity
Voice Actor: Corey Burton (US), (Japan)
Sunstreaker was one of several Autobots who glommed onto Hoist's job as a Hollywood extra in the hopes of becoming a movie star. This mainly resulted in him wearing a ridiculous alien mask and spouting out stilted, wooden dialogue.
Before the Decepticon attack on Autobot City, Sunstreaker was helping Kup move a roadblock. He was knocked over when Hot Rod and Daniel Witwicky drove through it.
Meanwhile, he was also on Moon Base One and helped pilot the shuttle that flew Optimus Prime and the Dinobots to Autobot City.
Universe
After the Pax Cybertronia, Sunstreaker left Cybertron with five other survivors of the Great War (Sideswipe, Roulette, Shadow Striker, and Trailbreaker). One year after Cybertron was reformatted into a technorganic planet, they returned. They were greeted by many of the Maximal and Predacon inhabitants and with vast media coverage.
However, what appeared to be celebratory fireworks struck the five Autobots and also the Maximals Silverbolt and Blackarachnia. They were transported to a firey chauldron deep within Unicron, where all but Trailbreaker were rebuilt painfully into new bodies.
Seeing an arena up ahead, the seven moved towards it, only to be attacked by a swarm of shape-shifting lava-like creatures. Sunstreaker and the others were overwhelmed and taken into the arena (or, the Pit), where they were caged along with a multitude of Transformers kidnapped from across the multiverse.
The Unicron-influenced ambience of the place was slowly driving the more violent of the group mad. This, of course, included Sunstreaker. He and Sideswipe were forced into combat in the arena, but were rescued by a reborn Optimus Primal. The group, sans a corrupted Blackarachnia, fled back to Cybertron.
Binaltech Asterisk
In the Japanese Binaltech Asterisk continuity, Sunstreaker is a member of the Cybertron (Autobot) Race Team, which may or may not have any other Transformers on it. He's sort of a mascot for them, and the team doesn't actually use him in races. He resents that people pay more attention to him as a promotional image than as a racecar.
Sunstreaker is partnered with - for unknown reasons - the human "race queen" model Junko Shiragami (known as Kelly in Robots In Disguise), and acts as her car.
It is said that Sunstreaker drives faster when he smells Junko's marigold-scented hair.
It is unclear whether the situations in the Binaltech Asterisk series take place in the proper Binaltech timeline.
