Chaos Header

The **Chaos Header** appeared in 2001 TV series called *Ultraman Cosmos*. The Chaos Header (カオスヘッダー *Kaosu Heddā*) is the head of the Chaos Organism and a former main antagonist of *Ultraman Cosmos* series. During his conflict with Earth and Ultraman Cosmos, the entity eventually took on physical manifestations to attack the Earth directly. It was eventually redeemed and returned to space.

Chaos Header was an artificial being created to bring justice to the galaxy. However, due to this obsession, he believed that violence was the only way to achieve peace and began to force a new order on the universe with an iron fist. Long before Cosmos set foot on Earth, Chaos Header rampaged on an unnamed planet Cosmos was protecting. He changed the planet's ecosystem and turned it into a wasteland. Cosmos, who felt guilty for his perceived failure, swore not to let another planet fall into Chaos Header's grasps.

The planet which became Chaos Header's next target was Juran. As Chaos Header rampaged on the planet, Parastan, the unknown protector of the planet fought and defeated him forcing him to retreat. This was witnessed by the planet's ancient civilians, who wrote the story down on a wall.

Chaos Header first appeared as chaos organisms over a city. Its appearance awed the citizens. Suddenly, the energy reaction of Chaos Organisms spiked and it fired a ray down on the city, destroying it. He later approached Kapuya Island and infected Lidorias. Once the chaos organism overtook her body, Chaos Lidorias went on a rampage attacking Japan, blindly under the virus' influence. Despite the brief success of Musashi in calming down the infected monster, Chaos Lidorias rampaged again when the SHARKS arrived to kill her. After having his plane shot down, Musashi merged with Ultraman Cosmos for the first time and stopped Chaos Lidorias's rampage by purifying her, expelling the chaos organisms from within Lidoras, freeing her.

Soon, many more monsters would become victims of the Chaos Header's virus, such as Golmede, Jelga, Parastan, Eligal, Neldorand, Taildas, Delgoran, Mazalgas and Galbas. Surprisingly, Chaos Header also knew Musashi's identity as Ultraman Cosmos' host.

Chaos Header had grown interested in human emotions ever since Akane's tragedy and searched for many suitable test subjects, returning them after he was done. Through human hatred it gained a humanoid form, the last victim was a family man, with a wife and son at home, heartbrokened by his disappearance. In the lair where he was kept the man sent a message to his son over the computer and the boy took on a long journey to find his father, while EYES, particularly Musashi, went in search of him. When EYES finally picked up on the boy's trail, Musashi put him to rest in his car and went inside a warehouse for his father. Inside he found the father possessed and unable to control his overstimulated rage. However after the small boy managed to get through the darkness and speak to his father, the true terror then became known. The chaos organisms evacuated his body but remembering the hatred were able to take on a humanoid form. A giant of death and destruction, the creature began to rampage. As it destoyed everything in sight Musashi summoned the strength of Ultraman Cosmos. The monster unleashed every weapon it had with the hero was being overpowered by its evil powers. That was until Cosmos called forth his Corona Mode and was able to fight back, but even then that wasn’t enough. On the ground, the father that Chaos Header Iblis had infected began to remember the good times he had with his son. These memories disturbed the fiend and weakened it, allowing Ultraman Cosmos to quickly fire off his Naybuster Ray, destroying it.

A while ago, EYES had to face an Eligal, a rare monster, and accidentally killed it. Shamed by this event, when another Eligal rose up, it was hoped they wouldn’t repeat the previous mistake. While their jets had to use their weapons, they did all they could before realizing that the monster was infected with the Chaos Header Virus. However, due to Musashi's overconfidence and newfound desire for strength, Cosmos ended up ending the creature's life even as he purged it of its infection.

When Chaos Eligal (after Chaos Header infected another species) appeared again, Musashi transformed into Ultraman Cosmos and attempted purify the monster with all his strength via Luna Extract. But in a twisted turn of events, the Luna Extract was absorbed and the Eligal turned into Chaos Header Mebut, beating the Ultra who had already expended most of his energy. Cosmos was left powerless and defeated by the tyrant for the first time. Cosmos separated from Musashi and took on a transparent appearance as he did when he first met Musashi.

Knowing it could not be stopped, Chaos Header Mebut appeared at point K3 and went on a rampage. Later, the tyrant tried to kill Cosmos who was on the verge of dying. Before EYES could arrive, Lidorias appeared and attacked the evil entity but was defeated. EYES unleashed all their weapons but they had little effect. Thankfully, when the creature infected Lidorias, the winged monster was capable of withstanding the virus and continued to battle. Chaos Header Mebut’s dreams of absolute destruction would seen be ended, however. In the time of the eclipse, Ultraman Cosmos rose just in time as Lidorias was downed. With new-found power upon his revival, he transformed into Corona Mode and brought the fight yet again. The titan was still unwilling to go down. As the eclipse ended, Cosmos awakened a new form, Eclipse Mode. The battle soon turned to Cosmos' favor. Even its use of Lidorias as a hostage could not save the villain as Cosmos' beam phased through and purified Lidorias before ending Mebut's existence.

One day, the EYES detected Chaos Organisms in Treasure Base. The sphere moved all over it and eventually chased after Musashi. As Musashi was forced outside, the being tried to assimilate Musashi by forcing him to transform into Cosmos as the being desired. Instead of corrupting the giant, the entity itself transformed into Chaos Ultraman and overpowered him, forcing him to revert back to Musashi and capturing him.

With Musashi captured, the Chaos Header was able to force Chaos Ultraman into action again when Neldorand emerged from the ground. Appearing yet again, Chaos Ultraman charged up his Darkness Wheel attack and turned the reptile into Chaos Neldorand. Devising a devious plan, Chaos Ultraman flew to Kapuya Island, and tried to infect the monster residents but failed due to the island's forcefield. The giant prepared an even larger attack than before, but before he could attack, his color timer began to flash. The being was forced to retreat. After the Chaos Header was killed and Musashi freed, the human called on Cosmos to take on Chaos Neldorand. Doing so also called on Chaos Ultraman whom was again on the offensive. As the two warriors of evil took on Cosmos, EYES attacked Chaos Ultraman, getting its attention. Seeing this, Cosmos took the opportunity to escape as EYES fired their Anti-Chaos Header missile on Neldorand, reverting him to normal and escorts him to safety. Transforming into Eclipse Mode, Cosmos was able to fully contend with the doppelganger. The two fought back and forth, trading blows as they tried to kill one another. Cosmos finally managed to defeat his evil twin using the Cosmium Beam, destroying the chaos clone. This was far from the end of the evil Ultraman, however.

Some afterwards, Chaos Ultraman would be summoned by the Chaos Header once again to destroy a SRC lab which was recently studying certain minerals in order to create an Anti-Chaos Header formula. While Team EYES faced the task of protecting the lab, Musashi transformed into Cosmos and assumed Eclipse mode. He gained the upper hand on the Chaos Ultra until another Chaos Header blast merged with the Ultra, upgrading him into a more fearsome menace: Chaos Ultraman Calamity.

Delivering untold power to the dark Ultra, the Chaos Header created a warrior so powerful that it even overpowered Ultraman Cosmos' Eclipse Mode. The hero’s color timer began to flash as Chaos Ultraman Calamity assaulted him with powerful attacks, forcing the giant to retreat. Without any real challenge, the warrior of chaos moved closer to the SRC base, ignoring the attacks from EYES' weapons.

Chaos Ultraman retreated but attacked another lab where the research was being continued. Musashi, however, recovered and again summoned Ultraman Cosmos to fight. Recharged, the giant called forth his Eclipse Mode yet again. The two battled it out, trading blows as they dodged and jumped at one another. On the ground, EYES had their own plans and fired an anti-Chaos weapon into Calamity’s chest, weakening him and giving Cosmos just enough time to charge and fire the Cosmium Beam, causing his evil twin to vanish yet again.

After the Chaos Chimera missile was completed, Team EYES and JADF baited the Chaos Ultraman Calamity with Cosmos' wave. But in a twisted turn, Chaos Galbas appeared and started to rampage, Chaos Ultraman Calamity appeared yet again, being summoned forth by the Chaos Header as revealed that the trap that EYES had set up had been predicted. It was attacked by EYES but it still waded through all their weapons. Ultraman Cosmos came to battle once more against his evil twin, but the monster was ready for him. After the hero unleashed his Golden Light Barrier and threw it at Calamity, the dark one fired back, blowing the guardian back. Galbas, having recovered tried its best to hold off the evil Ultra for a while in when Cosmos started to regain his energies. Reinforcements for Cosmos had come in the form of the JADF Defense Army who began unloading their weapons on the chaotic villain. As Cosmos watched on, the infamous Monster Hunter fired a Chimera Missile into Chaos Ultraman’s color timer. As it screamed in rage, Cosmos regained his stance and fired the Cosmium Beam, once again hitting the fiend and destroying it.

Another Eligal was turned into a slave of the Chaos Organism and used to draw Ultraman Cosmos away from the EYES base. After a battle with the hero, where Chaos Eligal pulled out all of its powers, the guardian managed to hit the monster with the Cosmium Bean, forcing the evil out of its body where the Chaos Header then appeared and revealed its true intentions, having gain its control over the Treasure Base and holding the staffs hostages.

Once Cosmos arrived at EYES base, Chaos Header summons Chaos Ultraman Calamity as the two flew to the moon where, after an exchange of words, the last fight between the pair exploded. With the Earth resting in the background, the two lashed out at one another, blocking and punching as they waded through one another’s attacks. However, as before, justice would prevail and the hero’s attacks exposed a brilliant, rare form of crystal underneath the moon’s surface.Exposing more of this, the villain was blinded by the light. With one final Cosmium Beam, the creature exploded, ending its rain. Despite its destruction, one last chaos warrior awaited to devastate Cosmos and the Earth: Chaos Darkness!

During a fight with a Chaos Ultraman on the moon, the Chaos Organisms appear and transform the fake Ultra into a devilish beast called "Chaos Darkness". Cosmos tries to put up a fight with the beast, but even with the assistance of EYES, Chaos Darkness beats Cosmos then retreats.

Later on, Chaos Darkness arrives on Earth and causes havoc. EYES tries to kill the monster, but Musashi tries to convince Chaos Darkness to leave. The creature refuses and attempts to kill Musashi until Ultraman Cosmos appears and fends off the beast. After nearly getting killed, Mogrudon, Bolgils, and Lidorias appear and use their cries, which manages to touch the inner goodness of Chaos Darkness. Having the chance, Cosmos uses the Luna Final attack while the Earth monsters use their roars to purify the Chaos Header, turning him into a golden and angelic form known as **Chaos Header 0**. Cosmos orders him to leave the Earth but Chaos refuses, unless Cosmos accompanies him. As the Chaos Header flies heavenward, he vanishes into light particles.

In *Ultraman Saga*, he becomes a guardian to Planet Juran where the Earth monsters habituate. He is seen talking to a Mienin, who stands on his arm.

In episode 37, Chaos Header appeared as Chaos Ultraman and split himself up with Chaosroids T and U. Soon enough, Black King, Kemur Man, and Ragon appeared to challenge them. They were all taken out, and exploded soon after, quickly; Chaosroid T by Kemur Man's goo, Chaosroid U by Ragon's radioactive ray, and Chaos Ultraman by Black King's Hell Magma.

Chaosroids T, U, and S as well as Chaos Ultraman reappeared in *Ultraman Ginga Theater Special: Ultra Monster ☆ Hero Battle Royale!* battling their good templates (save Chaos Ultraman who fought Ginga). Both sides fought each other until the Chaos Ultramen had them exhausted. Just as they were about to admit defeat, Ginga told Ultraman, Ultraseven, Ultraman Taro, and Ultraman Tiga not to give up and so they poured on their signature moves and fired at the imposters. They collided with the enemies' signature moves until Chaos Ultraman and the Chaosroids finally lost the beam volley and vanished a few seconds after being hit scoring a major victory for the Ultras.
