Anime Differences

A mysterious man clad in red (Dark blue in the manga), he has the same hair color and an identical appearance as Blade. He is another clone of The Second, much like Blade, also with a collar his markings are engraved "078.AA". But his right eye and heart rejected the Eden Seed . The resulting damage left him incomplete and deemed a failure, and was ordered to be destroyed. He was left for dead at a landfill, but he survived, and made it back to the laboratory. He briefly fought with Blade before he found and absorbed the remnants of the true Second in order to "become God". Doing so blew up the lab, and made him incredibly powerful. He deeply resents Blade and the scientists involved in their creation, on account of him being abandoned and Blade receiving the warmth and love he always felt had been robbed from him. His first memory is waking up in agony watching Blade be called a success while he was seen as a failure. This memory continues to haunt him. Through unknown means he rose trough the ranks of Simeon and took over interests in Black Spot, building Simeon tower and initiating the Needless Hunt. He wants Blade's body, because his own body is unstable and is only kept in check through complex machinery and absorbing other Needless. His fragments are Doppelganger and "Positive Feedback Zero", a more powerful form of Blade's "Zero". This ability works nearly the same as "Zero", however, whenever Arclight uses an ability, it will be stronger than the original and the more he uses that ability, the more powerful it becomes. He is also able to learn and use Fragments of Missing Links easily. When injured by Blade he snaps and transforms into a horrible monster at the lower half of his body eating people to recover his strength. After the PF Zero blast he is revealed to be alive but heavily damaged, with blast holes all over his upper body and his lower body a giant fleshy mess. He is in a life support crystal full of liquid. His current orders are to hunt down all resistance members, especially Cruz.
