Derelict Spacecraft

Derelict Spacecraft, roughly known as "Damaged Spacecraft" (壊れた宇宙船) in Japan, is the first stage of Mega Man Zero 3, a mysterious spacecraft that crash-landed in a snowy field. As it was emitting the same energy readings as the Dark Elf, Neo Arcadia and the Resistance went to investigate the area, and found Omega within the destroyed craft, which was emitting the energy. It is later revealed that it is the spacecraft where Omega was sealed in and exiled to space years ago.

Characteristics
The spaceship is colossal in both terms of size and energy production. Views from distance shows similarities in shape with a giant dual-bladed sword, as the space ship appears to be parted into two modules: a gray-colored horizontal propulsion system with a small circular thruster engine with yellow-colored regulator at the rear, directly connected to the main module which is lots thinner and larger with the primary bulge observation dock. The main module is large, however, a giant purple-colored exterior steel layer already consists more than half of its whole mass, features protection from space weathers and heavy impact, as it keeps the whole ark from destruction upon its crash. The real accessible rooms are located at the central, which is still gray colored, partly split at top with many bizarre red energy lines running towards the red core.

The interior design is quite straightforward. As when Zero approaching the spaceship, the inner walls has been partly collapsed, uncovered an unimaginable dense amounts of small electric circuits as well as small pipes inside. The wall is neutral and simply covered by a steel layer and simply colored, occasionally reveals some mechanisms or large energy-reading pipes. The ground is covered in a navy blue color. The room Omega appears is rather different from others solid structure outside, having a deeply blue colored background and an array of uncovered running giant pipes flows straight upwards.

Not much is known about the ship's capabilities beside the monstrous durability afters years in space and the massive impact with the Earth but still well-functioning. The ship also has a powerful anti gravitational system which balances the whole thing even after being affected by Earth's gravity. All the pipes indicating the huge power consumption of the whole ship dedicated just for monitoring Omega's statistics and activities, partly for the ship itself as well.

History
Long before the events of the Mega Man Zero series, where the Elf Wars has come to the closure, Omega, the last resort of Dr. Weil attempted to reverse the situation was ditched in, resulted in massive losses of the population, as Zero and X defeated Omega with the final attack, thus ended its crime age. Although it managed to survive the final battle, under the judgement of Neo Arcadia, the "Devil Reploid" was sentenced to perpetual exile on Earth's orbit within a spacecraft, whereas Dr. Weil was punished in a similar yet unprecedented manner. The ship was created with powerful defensive capabilities to prevent security damage from any interior or external impact causes to the ship, with the purpose to seal it as long as possible. The exact reason regards instead of Omega's destruction is unknown, and the ship's construction was unknown to any living being.

Two months after the Dark Elf incident in Mega Man Zero 2, strange energy readings similar to that of the Dark Elf were detected by the Resistance in a frozen tundra. A reconnaissance unit was dispatched to analyze the anomaly. Upon arriving at the location, they found the derelict spacecraft. The closer they got to the ship, the stronger the readings became and Neo Arcadian troops had already cordoned off the area. Zero fought his way through the hostile forces and entered the core of the broke ship, where fighting was already in progress. At the core, he saw Fefnir and Leviathan battling an enormous Reploid, Omega, but were unable to do so much as damage him. Weakened and damaged, the two Guardians teleported away, leaving Zero and Omega, whom Zero recognized as the one that called him, all by themselves, and later defeated it retreated to prevent further losts. It was revealed Weil who tampered the data and the ship's negative course.

Structure
The accessible modules are small compared to the whole ship. Zero first entering it through a crack caused by the great impact, and later got higher to the core room host where the Omega himself.

The place has many layers and eventually go straight upward. The surface is a mixture between grey and navy blue, where the background is darker and rather well-covered. No hazards present here however, but instead many square ice blocks appear and fall down as Zero approach, apparently due to the cold atmosphere outside when and where the ship was crashed. Many small mechaniloids are still present and active inside, mostly designed for protection over aggressive combat or being part of Neo Arcadia's forces.

Omega's Room
This room appears to be the central of the whole ship, where Omega was sealed in. It differ greatly from others solid structure outside, covered in a deep blue color and energy pipes. Omega is sealed in two and possibly more layers of walls, shown when his hands pushed Leviathan and Fefnir through one wall. The only boss, as suspected, Omega, still active presenting here.
