Garuda

In 1992, the Japanese government commissioned the creation of a spiritual successor to the Super X—the Garuda, a superweapon that would hopefully defeat Godzilla. Meant as the ultimate anti-Godzilla weapon, the Garuda was made obsolete by G-Force's Mechagodzilla, a mech created from researching and salvaging the remains of Mecha-King Ghidorah. Mechagodzilla however proved to have flaws, as it was defeated by Godzilla in their first encounter in 1994. In light of this, Kazuma Aoki proposed to modify and combine both the Garuda and Mechagodzilla, resulting in Super Mechagodzilla.

G-Force devised a plan where Mechagodzilla would destroy Godzilla's secondary brain, discovered from research into BabyGodzilla, using the G-Crusher. The plan had Baby Godzilla being used as bait to lure Godzilla. However, unexpectedly, Rodan appeared and stole Baby Godzilla's container from the helicopter transporting him. In order to retrieve Baby Godzilla, Mechagodzilla was dispatched to handle Rodan, with Kazuma Aoki following in the Garuda.

When it arrived, the Garuda tried to lead Rodan away from the container holding Baby Godzilla, but Rodan managed to incapacitate the Garuda. Kazuma quickly began repairing the weapon, and Mechagodzilla sent Rodan flying into a building with a plasma grenade. Right then, Godzilla appeared, looking for Baby Godzilla. Mechagodzilla tried to fight Godzilla but was no match. Kazuma managed to fully repair the Garuda in time and had it start bombarding Godzilla with firepower, distracting the monster. Mechagodzilla rammed into Godzilla using his thrusters, and finally it was decided that Mechagodzilla and Garuda needed to combine. Garuda docked into Mechagodzilla's shoulders, and Super Mechagodzilla was formed.

Super Mechagodzilla fought and eventually gained the upper hand against Godzilla, destroying his second brain. Before Mechagodzilla could finish Godzilla off however, Rodan woke up and gave up his life energy to Godzilla for the sake of Baby Godzilla. Godzilla woke up with tremendous energy and rapidly used his power and spiral atomic ray to destroy both Mechagodzilla and Garuda.
