edem ado

Ado Edem is the strongest of the Ether Liners, enhanced humans that create Knight Arms from their own bones. He originally didn't stand out within the war with the A-Rays, but became a prominent key figure and a trump card once the Aristoteles appeared. His whereabouts afterward are unknown.

Abilities

Edem's Knight Arm is a sword known as Slash Emperor, "that which consumes planets," which increases its own length to match the size of the target. The sword takes an unimaginable amount of True Ether in order to take form, which requires a massive convertible energy source. It uses the Earth itself in order to increase its size, and as it gets larger, the more of the Earth is simultaneously chipped away. Similarly to the old world, wherein the land was turned into particles to gain resources, Slash Emperor can be called the embodiment of human nature in that it destroys the world to protect humanity. It stays in a compact seed state while not in use, and once Edem awakens it by striking it into the Earth, it can be expanded and reinforced at the speed of his thoughts. While it seems to be emitting a blue aura, in actuality, it is showing the real blue sky by ripping apart the blood sky in order to show the barren world a glimpse of the "Truth." The glimpse of the "Truth" is supposedly very similar to the nature of Ea.

The sword is capable of slashing through Type Jupiter, an Aristoteles without a normal concept of death, in a single blow, and it later allows him to destroy Type-Saturn.
