If bright colors are nature's way of saying "Do not touch", then nature's got nothin' on Sunstorm. Come too close, and circuits will short, steel housing will begin to melt, and psyches will break as the mind struggles to comprehend. Science would explain that his body is aflame in radiation.
Sunstorm believes that he is the living embodiment of the Will of Primus, placed by the divine in this universe to deal righteous judgment on the blasphemous. His judgment is swift, painful, relentless, and punctuated with the recitation of Holy Writ. His power is only surpassed by his conviction.
Sunstorm was one of the Decepticon Seekers on Cybertron four million years ago. He shot at and together with Hotlink, Bitstream and Nacelle attacked the Autobots Wheeljack and Bumblebee when they came near, and that's about it.
Dreamwave comics continuity
Shockwave's experiments to fit a solar-powered fusion reactor into cloned Decepticon warriors reached their fruition in Sunstorm, a clone of the treacherous Starscream. Sunstorm's structure has been augmented to endure the enormous stresses involved. He was the perfect soldier; he possessed the ability to manipulate electromagnetic energy, enhanced regenerative capabilities, and a blank slate of a mind waiting to be written according to Shockwave's design.
When the Autobots took New Iacon from Shockwave, he hurriedly uploaded the compressed contents of the supercomputer Vector Sigma to multiple locations, including the hidden cloning lab near the Epsilon border where Sunstorm lay, awaiting instructions. The upload overwhelmed the lab's mainframe, spilling over into the only other available receptacle - Sunstorm.
Fleeing the fall of New Iacon, Decepticons Runabout and Runamuck broke into the Epsilon lab, unaware of its importance, intending to use it as a safehouse. After Runamuck amused himself by frying the lab's Mini-spy attendant, the duo accidentally awakened Sunstorm, who fried them… rather badly before his scrambled programming compelled him to depart, making his way to Earth.
Flying down to Earth, he tried to get Starscream to join him in his crusade, though Starscream believed his clone to be completely insane. Sunstorm battled with a number of Autobots, including Omega Supreme, eventually uncovering an enormous well of energy deep below the ocean, sealed with a mechanical door bearing a Cybertronian symbol. Jetfire and Bumblebee fought to stop him from unleashing whatever power the well held, until Jetfire, sensing that Sunstorm's internal fusion reactor was growing increasingly unstable, flew the overzealous seeker into orbit. Sunstorm's reactor went critical and exploded violently, completely obliterating both of them.
Sunstorm's almost supernatural durability was credited to his augmented molecular structure, similar to that of electrum. When Ratchet's Energy Siphon suppressed the effect, he was eaten away from within by the destructive energies of his own power source.
He is also apparently a fan of professional wrestling, having performed both a Stone Cold Stunner and DDT when engaging in close combat.
3H comic continuity
An alternate-universe version of Sunstorm was one of Megazarak's loyal inner circle. His radioactive condition was the result of an accident at the manufacturing facility during his birth. He was apparently a Child of Primus, though it is not known if or how he participated in the Universe war. A Minion of Unicron named Sunstorm did appear in that conflict, but there is no indication that they are the same individual.

- Originally sold only in a separately-packaged-toys set with Hauler exclusive to e-Hobby, Sunstorm is a redeco of the original Starscream toy, transforming into an F-15 fighter jet. His coloration is inspired by --but not wholly accurate to for a variety of reasons-- a previously-unnamed "generic" Decepticon seen in the episode "More Than Meets the Eye, Part 1". Sunstorm was later reissued in 2008 due to the encore line, sold with a special comic in which he appears. The only difference is that the "Collector's Edition mark is on the other top corner and it now has a Takara Tomy mark instead, as well as the heat rub sign relocated to the other side.
- Sunstorm (6-inch Cybertron Heroes, 2007)
- A redeco of Titanium War Within Thundercracker.
A Heroes of Cybertron version of Sunstorm was given as a freebie to people who pre-registered at OTFCC 2003 for next year's OTFCC 2004. He was later made available for sale through the 3H website. A repaint of the mold used to make Starscream and the other Seekers in the Heroes of Cybertron line, Sunstorm's colors are inspired by the e-Hobby toy, but given more variety in its shades of orange.
