Mogo is not a social Green Lantern and its interactions with the rest of the DC universe are not well-documented. It avoids announcing its presence, preferring to represent itself using pseudonymous holograms. Mogo has allowed alien races to live on its surface and has been willing to change its climatic conditions to suit them. These inhabitants of Mogo may not always know that their home is alive and watching them.When Hal Jordan destroyed the Power Battery on Oa and slew the Guardians, Mogo lost contact with the Green Lantern energy that helped sustain him. He travelled to Sector 1014 to seek the aid of Ch'p, unaware that his friend had died long ago. Having relied on the emerald energy of the power battery to sustain him, Mogo lost consciousness and drifted through Sector 1014 until he was discovered by a nomadic alien race. These aliens proceeded to strip Mogo of his natural resources and pollute his environment. Mogo's body reacted instinctively, creating constructs to hinder the aliens' efforts to exploit his resources. Mogo was finally rescued by Kyle Rayner, who used his power ring to reawaken the sleeping giant. Mogo offered to allow the aliens to settle on him and offered to take care of all their needs, but the stubborn beings chose to abandon their settlements. Mogo later revealed to Rayner that he was relieved the aliens had left, and that he had planned to give them terrible weather in retaliation for their pollution.
