Akuma Egg

The Akuma Egg (生成工場 (プラント, Puranto)) is a strange device used by the Millennium Earl to make Akuma. It has the appearence of a giant blue coloured egg many times larger and wider then a normal human being. Exactly how the Akuma egg helps in making Akuma is unknown. The original Egg was located on the original Noah's Ark and, along with the rest of the Ark, was to be downloaded into the new Ark being created by the Earl.

During the events of the Noah's Ark arc, General Cross Marian infiltrate the Ark and, using the combined powers of the Grave of Maria and his shape-changing abilities, he was able to locate the egg, defeat it's skull guardians and take it. Since he moved it, it was among the last parts of the ark to be download, halted only by the combined efforts of Cross's magic and Allen Walker's reversal of the Ark's destruction.

Due to this interference, only 20% of the egg was downloaded to the new ark, making it worthless. This, along with the 14th's interference of the event of the Noah's Ark arc, made the Earl visibly angry for the first and currently only time in the series, an event that surprised the Noah Lulu Bell and made Lero hesitant and fearful.

Without the Egg, the Earl could not make more Akuma and so he had Lulu Bell launch an assault on the Black Order Headquarters, where the Egg was being stored and investigate. Using the new ark's doors, Lulu Bell and an army of level threes invaded and seized the egg, opening a door underneath and sending it back to the new ark. Allen Walker and Bookman, with later on the Generals, Noise Marie and Miranda Lotto, counter assaulted, and used Miranda's time powers to reverse the egg's descent to the new ark and bring it back to headquarters.

It was at this point it was shown opinion in the Black Order higher hierarchy was divided over the subject of the Egg, with Supervisor Komui wishing to destroy it, and Inspector Malcolm C. Levrier wishing to preserve it for future study. Komui's decision to destroy the egg won out and three of the generals, Cross, Klaud Nine and Winter Sokaro engaged Lulu Bell in battle to destroy the egg, slowly turning the tide in their favor.

Using some of their strongest techniques, they managed to gravely damage the egg as Miranda and Marie's attempts to keep the egg in place failed and it sank back down into the new ark. Lulu Bell commented the damage could still be repaired but then Allen Walker showed up and dealt the egg one final blow, shattering it into pieces, leaving Lulu Bell to sink down into the new ark, raging impotently and meeting the Earl at their prearranged meeting point with no egg.

Later on, the Earl, in a more serious and sinister human form, commented he was constructing a new Akuma Egg.

It has recently been shown that the Akuma Egg shards that Howard Link, Allen Walker's watcher and Levrier subordinate collected, was put to a troubling use. It was used as part of the Third Exorcist project, to fuse human beings with Akuma cells to give them unique and disturbing abilities to combat the Akuma.

Trivia

 * Exactly how the Akuma Egg factors in with the creation of Akuma is unknown.
 * Despite it being a significant plot device, little is known about the Akuma Egg.
 * The Earl commented that the original egg cost a lot of time, effort and resources to create, meaning despite being underway to create a new egg, it will most likely take a while still yet to complete. The failure to download the original egg into the new ark was partly the reason for the Earl's show of visible anger.
 * It is unknown if only one shard of the original egg was how much Howard Link was able to find in the aftermath of the invasion of HQ.
 * Central and HQ seem to know much of the Akuma Egg, at least enough to order General Cross to secure it as a top priority mission and to know it's properties enough to base and create an entire project on it before it's acquirement (the scale of the Third Exorcist Project means that plans for it must have been underway long before the egg was acquired; the little time passed between the acquirement of the egg and current events in the series make it a near impossibility otherwise).
