Orga オルガ

An ancient alien species that crash landed on Earth 60,000 million years ago. Due to prolonged exposure to radiation from space, the being had been converted into a quantum fluid state inside its space craft. The creature, however, retained the ability to control its ship through telepathy. Over time, the UFO became encased in rock at the bottom of the sea where it lay dormant for countless years.

Near the dawn of the new century, CCI (Crisis Control Intelligence) came across the dormant rock structure and attempted to hoist it out of the water with balloons. The Millennian, however, was awoken by the light of the underwater sea exploration vehicle. It then proceeded to take control and hosted up the ship out of the water on its own. The rock mass then stayed on the waters' surface, only moving in order to stay adjacent to the sun so it could bath in its light and absorb its energy. Eventually it was able to scan a nearby human to try and find the needed genetic materials it would require in order to maintain its form. The humans, though, proved to be of no use, so the rock took to the skies in search of other organisms.

The UFO eventually came across Godzilla who, when scanned, was seen to be the host of the Organizer G-1, which the Millennian figured would help aid it in maintaining its normal form. The UFO attacked and defeated Godzilla, but only to crash into the water nearby itself. Responding to the appearance of the UFO, Japan's Self Defense Force went into action in an attempt to restrain the UFO by roping it with steel cables. Their attempt was in vein, however, as the UFO quickly freed itself at dawn.

The alien craft then proceeded to head for Tokyo, were it rested atop the Tokyo Opera City Tower. The Millennian UFO then attempted to assimilate all the data in the metropolitan city with invisible tendrils. Weaving their way into the building, the extraterrestrial began to drain all the data it could. Attempts to stop it, including disabling the Internet and power, failed. From the City Tower, the data hacking spread like a virus through the city. With this wealth of knowledge, the being began to formulate a plan of conquest. Not only would it steal the Organizer G-1 from the King of the Monsters, it planned to transform Earth's atmosphere to better accommodate its own living conditions.

Come nightfall, the SDF again attempted to deal with the UFO and stop the city-wide hack. This time they planted Bomb Blast mines at the top of the Tokyo Opera City Tower where the craft rested. The mines failed to deal with the Millennian, though, as the creature's craft was unscathed from the explosion. In retaliation, the extraterrestrial being destroyed the remainder of the building. Shortly afterwards, the UFO was greeted by Godzilla, the creature whom contained the genetic make up the Millennian needed. The UFO viciously attacked Godzilla, and was able to subdue the monster long enough to extract the needed genetic code, after crushing Godzilla with a building.

After obtaining the Organizer G-1, the Millennian slowly emerged from its ship in a ball-like form, which quickly changed to resemble its true appearance. Unfortunately, the Millennian failed to anticipate the horrific side-effects of the radiation spawned cells, as the creature begun to mutate uncontrollably before collapsing to the ground in a hulking mass.

• Known in Japanese as a "Millennian" (ミレニアン - Mirenian), the creature rarely has their name noted in English. The 2005 publication Godzilla: Toho Monster Picture Book (ISBN: 4092800525) is an exception, though, and does list the alien as "Millenian" with one 'n'. This is generally considered to be a typo, as other sources, such as Orga's listing for Godzilla on Playstation 3, cite the aliens as the "Millennian" in English.
• In Hiroshi Kashiwabara's Godzilla 2000: Millennium manga adaptation, the Millennian species is presented as a swarm intelligent collective. Kashiwabara's work is famous for taking strong deviations from the source material, though, and the movie presents no evidence that there was more than one Millennian involved in the actions in the film.
  
  

The final result of the Organizer G-1 on the Millennian. Orga was a mammoth creature compared to the slender appearance of the original alien. Equipped with giant claws and a large protruding back, the monster had mutated into a state that was even larger than Godzilla. Twisted and unrecognizable as a result of the volatile changes, the monster was an abomination. Characteristics appeared both influenced by Godzilla, but also taking properties from even the Millennian UFO. As part of the transformation, the creature was bestowed shoulder cannon. Like the flying craft of the species for which it shared a telepathic link, Orga even adapted the Rupture Attack beam of its ship.

Despite its menacing appearance, though, the King of the Monsters quickly rushed in and attacked the hulking monster. Orga seemed confused at these turn of events. Either due to shock from its own transformation or a general degrading of its intelligence, the nuclear saurian was able to land several blows before its alien opponent finally grasped the situation. Once up to speed, the creature fought back ferociously, attempting to fend off the onslaught from Godzilla. This included smash the nuclear menace in the face with its giant claw before firing its Rupture Attack beam, which sent Godzilla flying into a nearby building.

Having created a distance between them and collecting its composure, Orga called on its nearly destroyed ship to aid it in battle. The alien abomination next began to evolve its strategy, causing its shoulder cannon to glow as it leaped a great distance away. This was just a diversion, though, as the extraterrestrial creature knocked Godzilla over by ramming the UFO remains into him.

This tactic, however, did little more than anger the King of the Monsters. As Godzilla's spines started to glow, Orga positioned the UFO to absorb the impact of his foe's atomic ray. However, the King of the Monsters made quick work of it with another blast of his atomic ray. With the UFO decimated, Godzilla continued to strike the alien being, but the damage inflicted was quickly overcome by the creature's healing factor. A trait that was given to the beast thanks to the properties inherit in its rival's genetic material.

Orga had another trick up its sleeves, though. As Godzilla and the alien attacked in each in close combat, the mutated Millennian bit into its opponent. While its previous form could absorb energy through tentacles, its current hulking state was bestowed the ability to do so through its bite. Godzilla watched as Orga's skin turned green and began to take on the properties of the King of the Monsters. Despite the alien beast's efforts, though, Godzilla quickly dislodged Orga with a close range blast of its atomic ray. The attack did considerable damage, blowing off the alien's shoulder and with it the shoulder cannon.

As Orga's healing factor kicked in, the beast started to revert back to its gray skin tone. The creature needed to consume more of the King of the Monsters, now desiring more of Godzilla's power. The nuclear menace, though, supercharged his atomic ray and leveled Orga and the area around him, casting the alien into a conflagration. As the alien burned, a charred version of the monster emerged from the flames. Flesh hanging from his face and horribly burned, Orga slowly advanced, his healing factor still working enough to heal his wounds.

When it looked like Godzilla was running out of options to end the battle, Orga shifted its strategy as it completely opened its mouth. With its jaws stretched to a drastic degree, the monster then begun to withdraw its own stomach in order to consume its foe. Godzilla seized the opportunity and charged head first into Orga's mouth. The brutish alien then slowly started to consume the creature. As Godzilla slipped further into the beast's stomach, Orga continued to mutate...

• Orga was portrayed by suit actor Makoto Ito.
• Designed by Hideo Okamoto, the alien monster suit was modeled by Shinichi Wakasa.
• The Large Picture Book of Godzilla: Toho Special Effects Movie World (ISBN: 4873765587) lists Orga's weapons as "Wide Open Mouth" (大きく開く口 - Okiku Hiraku Kuchi), "Bite" (噛みつき - Kamitsuki), "Rupture Attack" (破動攻撃 - Yabu Do Kogeki) and "Super Psychic Attack" (超念動攻撃 - Cho Nen Do Kogeki). According to the entry in the Kaiju Guide of the Playstation 3/4 game Godzilla, though, Orga's attacks are instead listed as "Pulsating plasma bullets", "Energy absorption" and "Super-psychokinesis". Alternatively, in the manual for Godzilla: Save the Earth, Orga's beam weapon is just called a "Shoulder Cannon" while his ability to absorb is called "Absorb Essence". The game does add game unique attacks on top of this, though, such as "Paralyzing Goo".
• Orga has a walking speed of 30 kilometers per hour. Noted in the Godzilla Dictionary: New Edition (ISBN: 4773087250).
• Although Orga has a wide range of sounds, one of the more distinctive cries of the monster was lifted from the roar of Cretaceous King Ghidorah from Rebirth of Mothra III (1998).
• A version of the Orga suit exists which has the left shoulder blown off and can be seen in production stills before the CGI (computer graphic imagery) was added.
• Orga's name is derived from Godzilla's regenerative properties through Organizer G-1 (オルガナイザーG1 - Oruganaiza G1), shortening the name to just the first four letters. This causes issues in the American version as the ability was renamed "Regenerator G1". However, since Orga is never mentioned by name in the movie, it's a small issue.
• For the American version of Godzilla 2000: Millennium (1999), Orga was given a new roar. Part of this new roar incorporated distorted audio of the five year old daughter of John Adams, sound effect editor on the US version. Michael Schlesinger, producer of the American version, stated the reason for replacing was that the old one sounded like a "small animal". This fact is revealed in the commentary track of the Tristar Godzilla 2000 DVD.
  
  

With Godzilla caught in his maw, Orga began to rapidly absorb his foe's energy. The process caused the extraterrestrial to evolve, changing into the second Orga phase.

The alien creature's color slowly started to change green while rows of jagged dorsal fins emerged from its back. The abomination managed to grow, increasing his own mass, before Godzilla finally unleashed his Nuclear Pulse while inside Orga's mouth. Unable to react in time, Orga was helpless in his current situation as the powerful blast disintegrated the monster's upper half, killing the former Millennian.

• This third form of the Millennian is cited in numerous books. The Ultimate Godzilla 2000: Millennium Super Encyclopedia (ISBN: 4063044513) is one example where it lists the main form as "Orga Phase I" (フェイズI - Feizu I) and the final form as "Orga Phase II" (フェイズII - Feizu II).
• Despite being heavier, the height and length of Orga's second phase are listed as the same as his first phase in books such as The Godzilla Chronicles Vol. 3 (ISBN: 4812405815). However, the monster's new dorsal fins stretch much higher than his body due to his hunched mannerisms. Consequently, the creature logically should have been bigger than his earlier form.
• Although much of Orga's second phase appearance is achieved through CGI (computer graphic imagery), a prop, which can be seen in production stills, was created for shots that do feature the "half Orga, half Godzilla" look for the character.
