Spaceknights is a name used by at least three distinct groups of fictional characters appearing in American comic books published by Marvel Comics. The better-known group is a core concept of the 1980s comic book Rom Spaceknight, while the other two are far more recent creations and not much is yet known about them.
The original Spaceknights are an organization appearing in the Marvel Comics universe. It is an elite group of cyborg humanoids from the planet Galador, created to battle the Dire Wraiths. Rom the Spaceknight is the most well-known member.
The idea of the Spaceknights was invented by the Parker Brothers toy company as part of the background for their toy character of Rom, but it was developed in the Marvel Rom comic, in 1979, by Bill Mantlo and Sal Buscema. Marvel retains ownership of the Spaceknight characters today.
Galador was located in a galaxy known only as "The Golden Galaxy." Galador was a paradisaical planet, with very advanced technology. Galadorians seem to be identical to normal humans, though why this is so was never explained. Also, it would seem Galadorians have a longer lifespan than Earth humans. Two hundred years ago, the planet was ruled by a man known as "The Prime Director" and its scientists had already developed a class of angel-like warriors using genetic engineering. However, when it was discovered that the evil shapeshifters known as the Dire Wraiths were invading their galaxy, the Galadorian government decided that it would be necessary to create cyborg warriors to defend the planet from them. The Prime Director himself asked the people of Galador to volunteer, promising them that their "humanity" (the body parts that would need to be removed to implant the Spaceknights' Armor) would be preserved frozen and later restored to them after the threat had passed. At first the Galadorians were hesitant, until a young man called Rom became the first volunteer. Inspired by his example, a total of 1,000 Galadorians underwent the process, and were transformed into Spaceknights- each superstrong and capable of space flight, but each having a different special power or weapon, as well as an individual form and codename. Rom was given the Neutralizer, Galador's most powerful weapon, to use.
