Technical name: Gravity Shockwave Generating Tool (referred to as the "G-Tool" or "Hyper Tool" before its introduction). A giant hammer containing an artificial gravity well at its center that generates a "custom" shockwave, transforming all particles in contact with its striking surface into photons below the atomic level. It was designed as a new finishing move for GaoGaiGar due to the health complications that Guy's repeated use of Hell and Heaven had caused. The Hammer has more than enough power to pulverize the Zonder Robos. King J-Der's Generating Armor can hold off the Hammer for a time - the only forces known to have blocked the Hammer completely are Repli-Star GaoGaiGar's Hell and Heaven (which destroyed the Hammer) and Zonuda's invulnerable Barrier System. The Hammer was developed based on the data for the Goldion Nails on Genesic GaoGaiGar's hands, which possess the same properties. In order for GaoGaiGar to use the Hammer, approval from Koutarou Taiga is required, signified by the Chief pulling out a key from his personal keyholder and turning it in the keyhole on an activation panel, which will unveil another computer system to the operator (usually Mikoto), followed by the operator revealing a card and swiping it on a slot in the new panel, activating the Goldion Hammer. Initially, wielding the Hammer directly caused severe damage to GaoGaiGar. This situation was temporary resolved by using the Dimension Plier to wield the Hammer (which damaged the Plier instead), however a permanent solution was still needed, so the Hyper Tool was incorporated into GGG's Super-AI robot GMX-GH101 GoldyMarg, using the "Marg Hand" system in order to properly channel and control the Hammer's power. If required, the hammer section can be detached from the handle.
