— The Controller of Planet X addresses Shinichi Ozaki, Douglas Gordon, Anna Otonashi, and Miyuki Otonashi after assassinating the Xilien Commander (Godzilla: Final Wars)

The Controller of Planet X (X星人統制官,   Ekkusu Seijin Tōsei-kan, lit. X Alien Control Officer) is the leader of the Xiliens in Invasion of Astro-Monster and Godzilla: Final Wars.


In Invasion of Astro-Monster, the Controller is cold and manipulative, allowing his life to be run by a computer that controlled the lives of all Xiliens. The Controller was willing to conquer the Earth peacefully, giving the human race time to surrender without any bloodshed, but was more than willing to order the deaths of countless humans when they would not comply.

In Godzilla: Final Wars, the Controller appears to be mentally unstable, as he feels no remorse in killing his superior, the Xilien Commander, who is presumably his mentor. The Controller is prone to untimely fits of hysterical laughter, like when one of his monsters is defeated, when Godzilla is released, or when he is beaten in hand to hand combat by Shinichi Ozaki. The Controller is also prone to violent outbursts of rage. He becomes very angry when one of his monsters is defeated, or when he is outsmarted by one of the humans, often to the point of him jumping up and down and flailing his arms in anger. However, these outbursts are unusually short, and he can snap between near-manic anger to a cool and emotionless state in the space of a few seconds.


Showa series

Invasion of Astro-Monster

When astronauts Glenn and Fuji arrived on Planet X, the Controller brought them into a complex under the planet's surface, where he stated that he and the Xiliens required the Earthlings' assistance. The Controller told them that Planet X was being terrorized by King Ghidorah, called "Monster Zero" by the Xiliens, and that they wanted Godzilla and Rodan to be brought to Planet X to fight him off. The Controller promised a miracle drug capable of curing cancer in exchange for the Earthlings' help, and asked Glenn and Fuji to speak to Earth's leaders. The Controller secretly came to Earth in an Xilien UFO, hiding under Lake Myojin. Eventually, the Xiliens' presence was discovered by the humans and the Controller arranged a meeting with Earth's leaders. The Controller revealed the location of Godzilla and Rodan, and had two UFOs capture them. The Controller then invited Glenn, Fuji and their commander Dr. Sakurai on board his ship to witness the plan take place. When they arrived on Planet X, they witnessed Godzilla and Rodan battle and defeat King Ghidorah, with the Controller proclaiming it to be a great victory. He then sent the three back to Earth on a replica of their spaceship, the P-1. When they returned to Earth, they played the tape supposedly containing the cure for cancer, but instead discovered it contained an ultimatum from the Controller, demanding the Earth surrender to Planet X. The Xiliens soon besieged the Earth with their UFOs and the three mind-controlled monsters, Godzilla, Rodan and King Ghidorah. Using the A-Cycle Light Ray Gun, the people of Earth severed the Xiliens' control over the monsters, and then broadcast a sound across the Earth that was lethal to the Xiliens. The invasion a failure and his ship on the brink of destruction, the Controller proclaimed that the Xiliens would escape into the future and pressed a button, which caused all of the Xiliens' ships and bases on the Earth to explode.

Millennium series

Godzilla: Final Wars

The Controller revealed himself to the people of Earth alongside his superior, the Xilien Commander, claiming that he and the Xiliens had come to Earth to save the planet from an incoming asteroid called Gorath, that would soon impact and destroy the Earth. While the people of Earth initially embraced the Xiliens, the Controller grew impatient with the Commander, who wanted to harvest the humans' mitochondria through peaceful means with minimal violence, while the Controller preferred to annihilate their civilization immediately using the Xiliens' superior technology and enslave them. Eventually, members of the Earth Defense Force discovered that the Xiliens were replacing high-ranking Earth officials with disguised members of their race. A group of them confronted the Controller and his superior while they and the United Nations Secretary General were being interviewed live by Anna Otonashi. Douglas Gordon shot the Secretary General, causing his head to split open and revealing him as an Xilien. The Commander attempted to defuse the situation, but the Controller simply shot and killed him. The Controller declared himself the new leader of the Xiliens and used his powers to mind control the EDF's mutant soldiers, forcing them to attack the other humans. The Controller then returned to the Xilien Mothership and ordered all of the kaiju under their control to be released.

When the Controller learned that the Gotengo had survived and was en route to Antarctica, he sent Gigan to destroy it. The Gotengo freed Godzilla from Area G, and he quickly defeated Gigan. The Controller proceeded to unleash countless monsters against Godzilla, including Zilla, Kamacuras, Kumonga, Anguirus, Rodan, King Caesar, Ebirah and Hedorah, all of which fell. The Controller finally unleashed Monster X to battle Godzilla in Tokyo, while the modified Gigan battled Mothra. When the Xilien Mothership was boarded by the Gotengo, the Controller had his underlings capture the crew and bring them to him. The Controller taunted them, explaining that humans were "cattle" and that he planned to enslave and breed the humans so their mitochondria could be harvested as a food source for the Xiliens. He also revealed that the mutants on Earth were a result of humans and Xiliens interbreeding in the past. Some rare individuals called "Keizers" could obtain incredible powers from this combination of DNA, and the Controller revealed that both he and Shinichi Ozaki were among them. The Controller took control of Ozaki and had him attack his allies, but Miyuki Otonashi was able to free Ozaki from his control using the Shobijin's sacred dagger. Ozaki and the Controller then battled while Gordon, the rest of the crew, and the world leaders taken prisoner by the Xiliens fought their way back to the Gotengo. Channeling all of his hidden power, Ozaki defeated the Controller, leaving him lying on the ground. The Controller laughed, stating that he would not die alone as the ship began to self-destruct. Ozaki reached the Gotengo and escaped with the ship, while the Controller screamed defiantly as the Mothership exploded with him in it.
