In addition to the standard powers of a Green Lantern Power Ring, Mogo can also alter his weather and surface conditions such as plant growth, and travel through space at faster-than-light speeds. Mogo has a form of sensory or extrasensory awareness of what is happening around and on it. However, his wellbeing is largely sustained by the constant supply of energy from a Green Lantern power battery. Without it, he eventually loses his strength and even falls into a seemingly comatose state. Mogo also telepathically guides the Green Lantern Power rings to their bearer.
