The Xeronians were a peaceful society. When they were about to be attacked by another race, their King Randau subjected himself to a treatment in the solar chamber, which turned him into the perfect warrior, the Space Parasite. After he defeated the aliens, he left their planet to find stronger opponents until he found himself battling the Hulk. The Xeronians replaced Randau with a new King and hoped he would die himself, but they eventually found him on Earth. Realizing Randau had become too strong a threat, the Xeronians remotely destroyed Randau's ship, apparently killing Randau as well.^[1] Randau was later revived.^[3]

Randau, the Space Parasite

• Although the Official Handbook stated that Xeronians have five eyes but only use two at any one time, every Xeronian except Randau has only ever been depicted as having a single eye. Since Randau was similarly shown to have only one eye prior to his transformation, it could be that his multiple eyes were another result of his mutation.

Xeronians are not related to Xeron the Starslayer.
