Margus is a Kronan. He and his friend Korg went to the planet Earth where they hoped to capture a native, but they encountered Thor and Beta Ray Bill. The Kronans were defeated and fled through a wormhole, and Bill followed. The Kronans and Bill crashed on Sakaar and were forced into the gladiator games, though Korg was separated from the others. Margus and the other Kronans were brainwashed into mindless brutes. They were put into a pit of lava in the center of the coliseum with the Great Devil Corker. Margus killed Laven Skee so Korg killed him.
