Before the Millennian UFO sheds the debris on its exterior, it is referred to as a rock mass (岩塊. gankai) In publications contemporary to Godzilla 2000: Millennium, such as its theater program and Super Complete Works book, the UFO's true form is simply listed as Giant UFO (巨大UFO. Kyodai Yūfō) The name "Millennian UFO" (ミレニアンUFO, derived from the Mirenian Yūfō)alien race to which the craft belongs, arose as early as 2005 with books like Godzilla Toho Giant Monster Pictorial Book, which also gives the name in English. Sources since have varied between the two names, and both remain in usage. Interestingly, Godzilla.com, the official international website of the Godzilla series, lists the craft as "Millennian UFO," but the picture used for it contains 巨大UFO ("Giant UFO") in its filename.
When the Millennian UFO first appeared, it looked like a massive rock due to having its exterior being covered by rocks and sand during its millions of years being dormant. After it shed off this rock, it looked like a vaguely bullet-like pod, with a white undercarriage and blue fuselage.
Millions of years ago, the Millennian UFO traveled through the far reaches of space, its occupants having long since discarded their organic bodies to endure the long voyage. The UFO crash landed on Earth in the ocean, and remained there for at least 60 million years. In 2000, the ship, initially believed to be an immense meteorite as it was encased in a layer of rock, was retrieved from the Japan Trench by the Crisis Control Intelligence Agency. With the light of a morning's sunrise, it escaped, and began to fly towards Japan. As Godzilla was advancing on the Tokai Nuclear Power Plant, the ship engaged the kaiju. During the encounter, a strike from Godzilla's atomic breath revealed the UFO's hull, but the UFO blasted its adversary into the ocean through the use of its laser cannon, putting an abrupt end to the JSDF's campaign against Godzilla. The UFO flew to the city of Kashima and landed offshore, ceasing activity long enough for the JSDF to construct an electromagnetic barrier around it, but again it escaped as the overcast skies cleared. The ship traveled to Shinjuku, destroying several CCI helicopters pursuing it with shockwaves, before landing atop the Tokyo Opera City Tower. As night fell, it began extracting data from the City Tower's supercomputer and all linked networks throughout the city. As it started altering the atmosphere's oxygen levels, the JSDF attempted to destroy it with Blast Bombs planted inside the Tower, but to no effect, and the UFO retaliated by destroying the building entirely and broadcasting its occupants' declaration of conquest. Godzilla resurfaced in Tokyo Bay and came ashore to confront it. Attempting to subdue Godzilla with psychokinetically-animated infrastructural cables, blasts from its laser cannon and shockwaves, the UFO eventually toppled a building onto Godzilla, successfully immobilizing him long enough retrieve a sample of his genetic material to use the regenerative properties of Organizer G-1. From a swirling organic mass manifested below the craft, the Millennian emerged, having regained its organic form. However, unable to separate Organizer G-1 from Godzilla's genome, the alien mutated into Orga. Godzilla then emerged from the rubble and destroyed the ship with a direct hit from his atomic breath, splitting it in half. During Orga's fight with Godzilla, the alien mutant used psychokinesis to manipulate the front half of the UFO to attack Godzilla by surprise and later to shield himself from Godzilla's ray, destroying the craft totally.
The Millennian UFO is powered by solar energy, and any exposure to sunlight after being dormant will immediately restore its power.
The Millennian UFO can fly at various speeds.
The Millennian UFO can manipulate energy in various ways.
The Millennian UFO can fire lasers from a side-mounted cannon.
The Millennian UFO can extend energy tentacles to extract genetic material from other organisms and data from computers.
The Millennian UFO can fire powerful shockwaves down to the ground from a port on its underside; these shockwaves were strong enough to blow buildings to pieces and briefly stun Godzilla.
Under the control of the Millennians, the UFO can use a form of psychokinesis to rip electrical cables from the ground and use them to restrain Godzilla. Once attached, these cables were strong enough to hold Godzilla in place, and could be pulled at great speed to drag him down to and along the streets of Tokyo.

In Godzilla: Rulers of Earth #6, the Cryogs sent Gigan to Area 51 to retrieve the Millennian UFO. After the UFO was freed, it accompanied Gigan to Las Vegas and began to terrorize the city until Godzilla and MOGUERA arrived. During the battle, Gigan restrained Godzilla and allowed the UFO to absorb his genetic material and release Orga.
