"We are numerous, whether in a single body or several, we act under the same will. There will be a new order."
"I see that. The planets whose ecosystems you have changed, is that all a part of evolution?"
"Correct. The remaining creatures of those planets will build up a new order under the same will. For this, sometimes, there will be sacrifices."

―Chaos Ultraman Calamity explains his goal to Cosmos

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 a term created by Team EYES member Doigaki for identification, but the entity had since adopted it as its own name.

Subtitle: Light Virus (光のウィルス Hikari no Uirusu)


Pre-Ultraman Cosmos

Chaos Header was an artificial being created to bring justice to the galaxy, having emerged in the nearest galaxy to the Milky Way, the Andromeda Galaxy. Exactly who created him is unknown, yet the being carried immense power and desired to follow his directive to the letter. However, due to this obsession with bringing about justice, 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, vowed to never let another planet fall into Chaos Header's grasp.

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.

Ultraman Cosmos

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 Kaburaya 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 JADF 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 Dolba. Surprisingly, Chaos Header also knew Musashi's identity as Ultraman Cosmos' host.

"Shinobu, is that transformed from a human?"
"No, Mr. Kano is here. That's neither a transformation nor a clone. That is probably a materialized form of Chaos Header."
"Materialized Chaos Header?

―Shinobu and Hiura, episode 25.

Cosmos vs Chaos Header Iblis

After an incident with using Akane's hatred to manifest a monster, Chaos Header gain interest in human emotions and started a series of kidnapping incidents. Through the emotion of hatred and possessing a human host named Ryoichi Kano, Chaos Header started to manifest its own independent form Iblis, which almost scored a victory against Ultraman Cosmos' Corona Mode until Kano's compassion to his son, Shota, weakened the form for Cosmos to finish. As time passed, the virus developed it's own immunity to any of Cosmos' form of exorcism. After the death of Eligal, Chaos Header masqueraded as an infected version of the monster to trick Cosmos into wasting his energy and eventually unveiling itself as Chaos Header Mebut. Chaos Header would went on to a rampaging spree and trying to kill the weakened Cosmos, facing against Team EYES and Lidorias along the way. A partially energized Cosmos continued the fight and was further empowered into Eclipse Mode, using his new abilities to gain the upper hand of the fight and eventually defeating Chaos Header Mebut when the villain's attempt to use Lidorias as a meat shield was rendered moot.

The face of Chaos Header appeared in EYES Base.

With knowledge of Musashi Haruno as Cosmos' host, Chaos Header traced him all the way to Treasure Base and a semi-possession attempt during Cosmos' transformation resulted with the birth of Chaos Ultraman. After defeating Cosmos and imprisoning Musashi, Chaos Header used their newfound form to possess a Neldorand and fight against Team EYES. Musashi escaped thanks to his teammates freeing him and had Cosmos Eclipse Mode destroying the clone. Several months later, Chaos Header managed to trick the JADF forces into killing Mazalgas to prevent the humans from putting the monster's Chaos Chimera into use. When SRC try to recreate the formula, Chaos Ultraman was reformed to destroy the Scientific Analysis Center. Just as Cosmos was about to defeat the clone again, the Chaos Header energy from the Point P87 upgraded their clone into Chaos Ultraman Calamity, the clone now is capable of tanking all forms of Cosmos' attacks. As SRC successfully recreating the Chaos Chimera enzyme, the clone once again found itself at a disadvantage as both humans and Ultraman (including the help of a single monster) collaborated in their war against the space organism.

Chaos Header after its purification.

Chaos Ultraman Calamity's final battle was at the Moon, which Cosmos specifically choose due to its abundance of Soagg minerals to exploit his weakness again. However, that was when all the essence of Chaos Header (including those of P87 point) merged into Chaos Darkness through their mutual hatred against the Ultraman. It seemingly disappeared from Hiura's Chaos Chimera, but the entity landed on Earth, now being immune to all forms of resistance. With knowledge that the entity is simply misguided, Musashi attempted to achieve mutual understanding on both sides, but his efforts were in vain until he merged with Cosmos, using the Ultra's Luna Final and the accompanying cries of Mogrudon, Bolgils, and Lidorias managed to purify him into 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.

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.
