The Cryog emperor, Karkaro, and a group of his elite guard boarded Rhizon's ship and took Rhizon and his crew prisoner. Just then, a gigantic Cryog ship uncloaked itself. One of Rhizon's underlings asked what the meteor was, but Rhizon only responded that it 'wasn't meant for them.' Rhizon, knowing another ship was nearby, called out and demanded its occupants to reveal themselves. Shortly after the battle between Gigan and SpaceGodzilla, a meteor flew past Rhizon's ship. SpaceGodzilla then floated to Earth unopposed. Rhizon then unleashed Gigan to fight off SpaceGodzilla, but he too was defeated and badly damaged. Rhizon sent the two remaining Mechagodzillas to intercept SpaceGodzilla, but they were frozen in Earth's atmosphere and easily destroyed. Rhizon was enraged that they had lost control of Mecha-King Ghidorah and that only two Mechagodzillas had survived, but he found he had bigger problems when his ship was suddenly attacked by SpaceGodzilla. Rhizon and his crew took refuge on a spaceship and waited in Earth's orbit for an opportune time to strike again.

The defeated Rhizon ordered his remaining underlings to retreat to space and end their presence on Earth, at least for the time being. Mecha-King Ghidorah retreated under his own power while Godzilla destroyed the rest of the facility and departed with Anguirus. Godzilla and Anguirus managed to destroy the Mechagodzillas and severely damaged Mecha-King Ghidorah, severing the twins' telepathic control over him. Before the combined forces of the mechas could defeat Godzilla, Anguirus arrived to assist Godzilla. Mecha-King Ghidorah carried Godzilla to a robotics facility in Russia that had been converted into a giant arena where more Mechagodzillas were waiting. After Godzilla destroyed most of the Mechagodzillas, Rhizon sent his latest monster pawn, Mecha-King Ghidorah, to battle him. When Godzilla appears in Boston, Rhizon sends an entire fleet of Mechagodzillas to kill him once and for all. The Mechagodzilla almost managed to kill Anguirus, but was recalled after its firepower was demonstrated. He sent a Mechagodzilla to Antarctica to ambush Anguirus. Using their mind control capabilities, he convinced world leaders to purchase mass-produced Mechagodzillas to fend off kaiju attacks, hoping that it will eliminate any monsters that could resist his invasion. Anders and begins his plan to get revenge on Godzilla.įour years later, Rhizon was pretending to be a wealthy Russian warmonger and had acquired the assistance of the evil psychic twins Minette and Mallory. After the Devonians are eliminated, Rhizon kills Dr. He cooperates with CKR and gives them vital information in destroying the Devonians' capital. Rhizon actually survived the battle and took the form of a Devonian, pretending to be a refugee who is resisting his race's conquest of Earth. Biollante proceeded to tear the Cryogs' ship apart, seemingly killing all of them. Commander Rhizon called the Devonians to prepare for their ship's arrival so that it could be repaired, but were instead met by the Devonians' latest creation, Biollante. Jet Jaguar flew onto the ship and killed several more Cryogs and damaged the ship while rescuing Woods and Chavez. The Cryogs beamed Steven Woods and his partner Chavez onto their ship in an attempt to kill them, but many of their solders were killed by Woods and Chavez's Zero Cannons. Godzilla and Jet Jaguar double-teamed against Gigan until he was forced to retreat. Suddenly, Jet Jaguar arrived and flew down Orga's throat, then grew and caused Orga to explode. Unfortunately for the Cryogs, Orga went out of control and attempted to eat Gigan. MOGUERA arrived to even the battle, but Orga and Gigan began to overpower Godzilla and MOGUERA. Gigan pinned down Godzilla and allowed the UFO to absorb his DNA and become Orga. Gigan and the UFO proceeded to Las Vegas, where Godzilla was waiting for them. After the Devonians' plans failed, the Cryogs deployed the upgraded Gigan to retrieve the Millennian UFO from Area 51. The Cryogs retrieved Gigan following his battle with Kumonga and upgraded him. The Cryogs' Commander Rhizon, however, intended to betray the Devonians after they had outlived their usefulness. They initially had a shaky alliance with the Devonians to conquer the planet together and partition it equally. The Cryogs came to Earth in order to conquer it following the destruction of their homeworld by King Ghidorah.
