The Gravity Equalizer consists of a metal casing which wraps around the forearm of the user, a fire button which is operated by the thumb, and three outlets for the rays to be fired from. According to Kirby's words, this device cancels the gravity equation, so that the attraction of a planetoid no longer affects the objects shot by the device; causing them to uncontrollably float up into the sky. For some reason, however, the weapon was unreliable and failed after a few shots, but Donatello could still use it as a makeshift club.
