Karn

The planet Karn, or Korn, offers a surface of rocks, sand and various crystalline structures to its native lifeform, a slightly evolved ogreish race at least capable of fabricating itself weapons and houses.

Fiction

Marvel Generation 2 comic

The Cybertronian Empire was slaughtering the native population of Karn in hopes of baiting the Autobots out of hiding. The genocide, though failing to attract the Autobots' attention, was going according to plan until the Swarm arrived, which changed the Cybertronians' status from hunter to prey. Though the Swarm frightened the remaining Karnians, it ended up coincidentally saving their lives, as the Swarm had no interest in anything but the consumption of metal and metal alone. Swarm

Notes

• The captions in the original story featuring this world are split fifty-fifty as to whether the planet's name is "Karn" or "Korn". The AllSpark Almanac II went with "Karn", tipping the scales in support of that spelling.
