Alan controls the mystical power of the Starheart, an ancient artifact created by the Guardians of the Universe. Green Lantern has extensive energy manipulation powers able to effect the entire spectrum including gravity, radiation, heat, light. Creating Solid objects allows him to make Simple weapons, entrapments devices, common geometric shapes, gigantic hands and simple containers. It has been discovered that Alan's body is composed entirely of green flame. Recently the power of the starheart has been internalized by Alan Scott and no longer comes from the lantern or ring.
