The reincarnation of both Project Carthage and XANA’s copy Nephilim shares XANA’s memories along with his hatred for Aelita, the Lyoko warriors, and humans, but for now still obeys Dr. Lyon. He is arrogant in his powers, seeing himself as the AI version of a God. However he is unaware that he was made from XANA’s copy so he does not know XANA is still alive so he was surprised when he met Aelita and the TD Lyoko warriors when he expected to encounter the original ones.
He is easily angered as he wishes revenge on Aelita for the part her family and friends played in killing both his previous versions.
Nephilim was created when a scientist named Dr. Lyon combined a back up version of Project Carthage, a digital avatar he created along with the remains of XANA’s copy. He was then ordered to track the supercomputer Aelita’s father built and take control of it and Lyoko. Nephilim infected the supercomputer and lured Aelita and the warriors to Lyoko where he revealed himself. Even though he split his coding to infect the supercomputer he was strong enough to take on eight Lyoko warriors at once.
Not knowing why there are more humans in Lyoko Nephilim moved to get rid of them before going after Aelita to exact revenge. His power seems to rival even XANA’s, calling himself a league far beyond his.
Powers and Lyoko AbilitiesEdit
Avatar: Like XANA Nephilim has a digital avatar now but where XANA keeps a humanoid form Nephilim’s is much more monstrous.
Lance: Nephilim wields a huge lance in battle that can block almost any attack. He is proficient enough that he is able to fight almost half the Lyoko Warriors at one time and still be strong enough to fight from dawn till dusk.
Monster Mutation: All though Nephilim controls almost all of XANA’s old monsters he is able to upgrade them instantly and change them into newer, more powerful and more deadly versions.
Super Strength: Nephilim is strong enough to take on the Berserker and even win in a one on one battle.
Hive Mind: Like XANA Nephilim has a hive mind that allows him to order his monsters in battle.
Activating Towers: Nephilim is able to take control of towers in Lyoko like XANA and Shadow but they glow orange.
Data Manipulation: When Nephilim infects the supercomputer he leaves a piece of himself inside to take control of it. Even though he’s bound to the supercomputer like XANA was before he can remove it whenever he wants.
His name is the name of a race of half-Celestial humans, who are part angel and part human.
