Death Egg

 Death Egg

The Death Egg is a massive orbital fortress and space station, constructed by the late Dr. Ivo "Eggman" Robotnik 10 years before his death. It is the first and most famous of all Dr. Eggman's space stations. Hosting some of the Doctor's most deadly creations of all time, this vast stronghold serves as the scientist's ultimate weapon and a key component in his plots for world domination.
The Death Egg's first incarnation surfaced during the now-legendary "Death Egg Saga' when Dr. Eggman attempted to seize all seven Chaos Emeralds to finish his plans for the infamous space station. Despite the Doctor's plans, however, the Death Egg was knocked out of the sky by the combined efforts of Sonic and AJ "Tails" Prower. However, the Death Egg proved to be robust; surviving the fall from space and a failed re-launch before eventually making it back to orbit. Although the original station was destroyed at the end of the Angel Island Incident, Dr. Eggman continued to rebuild it, time and time again.

The common Death Egg is a spherical grey space station that resembles the face of Dr. Eggman, with concave eye sockets, a sharp nose, and a mustache rendered in kilometers of vacuum hardened plasma-steel. Its exact dimensions are kept classified although it is easily gargantuan; its mass and size are enough to destroy mountains, flatten forests, and force Angel Island down into the sea, and its face alone is enough to plug the vent of Angel Island's volcano. 

The Death Egg is the largest airship ever created by Dr. Eggman, and comes with weaponry and features to match. It is said to be Dr. Eggman's "ultimate weapon", suggesting it packs significant military power and destructive capabilities. It is designed to run off the chaos energy of either the Chaos Emeralds or the Master Emerald. However, it has been proven that it can run off other power sources as well.
In terms of armament, the Death Egg has numerous weapons systems installed, both for outward and inward defenses. Described as heavily fortified, its hull is covered in laser turrets and its insides are filled with weaponry and traps, such as electrical currents, rocket launchers, and laser cannons. Its eyes can also fire lasers hot enough to activate dormant volcanoes. The Death Egg's most powerful weapon however, is the Final Egg Blaster, a weapon capable of destroying entire clusters of stars.

The Death Egg is a massive orbital fortress and space station that was once owned by Dr. Eggman. After his death, the ship was shunted into a graveyard orbit at about 100,000 miles off the surface of Mobius.
