Eden

Eden (エデン) is a mysterious giant space fortress from the Mega Man Legends series that is equipped with a powerful explosive weapon and around 10,000 workers aboard. Eden was to be used as part of the Carbon Reinitialization Program. It was intended to launch an explosive device toward Kattelox Island in order to wipe out all of the Carbons present there and keep them from over-populating.

During the credit roll to Mega Man Legends 2, a significant amount more of these Eden-like structures can be seen surrounding the whole of the planet Terra (Earth). Presumably, they were all to be utilized in the true Carbon Reinitialization Program that was intended to wipe out all of the Carbons across the whole of Terra.

Eden is also featured as a level in the crossover game Namco x Capcom.

Mega Man Legends
On Kattelox Island there is a legend that every one-hundred years, a legendary disaster is to occur that will wipe out everything and everyone on the island. This legend began after the explorers John and Varley discovered the destroyed and empty island of Kattelox before the civilization of modern times was built there.

This legend stems from a past reinitialization of the island under the operation of the Master System.

Near the end of Mega Man Legends, the bureaucratic model Mega Man Juno activates Eden to initiate the reinitialization program in Kattelox Island that is supposed eliminate all Carbons (humans) on the island and prevent them from over-populating.

Juno estimates that they can complete their work in less than five minutes. Mega Man Volnutt appears and tries to stop Juno from completing his plan. Mega Man Juno then intends to keep Mega Man occupied until Eden is in range to receive transmissions.

After a battle, Mega Man Juno is finally defeated, but he manages to keep Mega Man Volnutt occupied long enough for Eden to achieve optimal altitude, and requests Eden to begin the reinitialization of the island and create a memory back-up of his systems, being backed up in Eden's central core, so that he can be reactivated again in the future.

When Eden is ready to start the reinitialization program and detonate the bomb, Data appears and requests Eden to interrupt the program. Data uses Mega Man's identity as a Purifier Unit (First-Class Purging Officer in Japan) to shut down the program. Data then requests that the computer delete Mega Man Juno's back-up data, citing that he malfunctioned and is currently a threat to the system. He passes to Mega Man Volnutt the bureaucratic authority for the district of Kattelox Island. Eden follows Data's orders and resumes standby mode, returning to its previous coordinates.

At that point, the reinitialization has been stopped and the explosive device returns to Eden. Eden then remains inactive and does not continue to pose any threat to Kattelox Island.

Namco × Capcom
In the end of Chapter 43 of the crossover Namco × Capcom, Mega Man Juno obtained the Eye of Atamoni in Dycroft to use its energy to power Eden, giving it enough power to dispose of all Carbons on the planet.

In Chapter 44, the party goes to Eden with the Gesellschaft to recover the Eye of Atamoni and stop Juno and the Grandmaster Meio. In Eden's Control Room, the party fights against some Gnosis (KOS-MOS using the Hilbert Effect to the party fight against them) and a Gorubesshu, and more enemies appear later, including Juno, the Grandmaster, and Saya, and they reveal their plans. Juno and the others are destroyed in the battle, and the party uses the Control Room to send Eden and everything inside it, including the Eye of Atamoni, deep into space to never be seen again.

In the end, the heroes return to Earth thinking the battle is over, however, Saya survived and hides in the Gesellschaft. Saya then fights against them in the last chapter.

Trivia

 * Eden is the name of the garden described in the biblical book of Genesis as being the place where the first man, Adam, and his wife, Eve, lived after they were created by God.
 * In the museum in Uptown there is an antique painting with the description "It looks like the person wearing blue armor is fighting with a frightening monster! I wonder what the thing that looks like an eye there is supposed to symbolize?". The frightening monster resembles Juno, while the eye in the sky resembles Eden or the explosive that is sent down to Terra from Eden.
 * In Mega Man Legends 2, the center of Glyde's Base in Calbania Island has a large inclined structure with a design similar to Eden. It is possibly the remnants of a past reinitialization of Calbania Island, similar to the reinitialization program of Kattelox Island.
 * In a gameplay video from Mega Man Legends 3, a large monolith similar to Eden appears above Klickelan Island.
