Transformers: Generation 1
Sunbeam is a beach bum who transforms into a light burst discharger. He is partnered with the Decepticon Needlenose.
In the Marvel Comics Transformers stories Nebulans are depicted as human-looking aliens, while in the animated series they are green-skinned aliens. In the Ladybird Books stories the Nebulans are human-sized robots.
Sunbeam shares his name with another Hasbro toy character, a My Little Pony first introduced in 1983.
Sunbeam was an irresponsible beach bum on Nebulos before he discovered the Decepticons. His greatest ambition was to go rocket-surfing on the 50-foot tall waves that occurred annually on his home planet's Magna Beach. But, having accomplished that, he needed new challenges. So, for the opportunity to rocket-surf on other worlds, he joined the Decepticons and underwent bio-engineering. He was then paired with Needlenose and trained in aerial combat. He views the warrior aspect of his job as a necessary nuisance. He says, "If I have to scrap a few 'Bots so I can ride the Mercury Breakers on Cybertron, well like, hey, no problem, dude." Sunbeam converts to a solar-powered light-burst discharger. A flash from his muzzle causes temporary blindness in all opponents except those whose optical modules are properly shielded. Sunbeam's firepower is diminished in situations when the sun isn't shining.
Note: Events exclusive to the Marvel UK Transformers comics appear in italics.
Needlenose appeared in issue #229 and #239 of the UK Marvel Comics Transformers comic, but he used guns that did not appear to be his Targetmaster partners.
Needlenose and his Targetmasters had a biography printed in the back of issue #64 of the US Marvel Transformers comic.
