Daxam is a planet that revolves around a red star.
Populated by Humanoid residents, Daxam was victim to two major alien invasions in the 20th century. During the Imperiex War, Daxam was besieged by dozens of Imperiex Probes, which were responsible for killing hundreds of Daxamites. The Earth heroes known as the JSA, as well as a full complement of reserves, traveled to Daxam and liberated the planet without suffering a single casualty.
Many years later, Daxam was taken over by the galactic despot known as Mongul. Armed with six Qwardian Power Rings, Mongul made Daxam the new base of operations for the Sinestro Corps. Green Lanterns Arisia and Sodam Yat (himself a Daxamite) flew to Daxam to try and save the people from Mongul's brutality. After a hardfought battle, Sodam realized that the only way to save Daxam was to empower the people to fight for themselves. Sodam flew to Daxam's red sun and infused it with the power of Ion, transforming it from a red star into a yellow star. The yellow wavelength radiation gave the Daxamites superior physical capabilities, as well as the ability to fly and project thermal radiation from their eyes (similar to a Kryptonian). This heroic act temporarily trapped Yat inside the star, but the people of Daxam now had the power to defend themselves. Arisia volunteered to train the Daxamites and forge an underground rebellion to oust Mongul.
Eventually, though, Sodam left the star, restoring it to its original red color, and returned the Daxamites to normality.
- As part of their stringent xenophobic practices, space travel to and from Daxam is strictly forbidden.
