Nemesis (gen:LOCK)

"You have lost your chance. And now there is no choice. Kill the copy."

- Nemesis

"Let the good times roll."

- Nemesis using Julian Chase's catchphrase.

Julian Chase, also known as Nemesis, is one of the main antagonists of the Rooster Teeth animated webseries gen:LOCK. He was the result of main protagonist Julian Chase achieving gen:LOCK with a Holon that was then captured and altered by The Union, resulting in an evil version of Julian whose vengeful mind is trapped in a Holon.

He is voiced by Michael B. Jordan, who also voices the heroic version of Julian Chase and also portrayed Erik Killmonger in Black Panther.

History
Julian Chase was a Polity fighter pilot fighting with the Vanguard in their war against the Union. However, during an attack on New York City in 2068, Chase was shot down and was nearly killed. He was saved by the Polity's Experimental Science Unit and Dr. Rufus Weller, who found him compatible for the gen:LOCK program. He was eventually tested and was able to gen:LOCK with an experimental Holon mech, and began rigorous training in combat using his new Holon body.

Chase advanced quickly, and was soon able to join in missions and fight in the war using his Holon, proving exceedingly useful in the effort by defeating many Union forces. However, the Union was fascinated by the program and set out to capture Chase themselves. During one mission, Chase's Holon was overpowered and captured by the Union, stealing away the technology and Chase's mind in the process. Dr. Weller was able to restore Chase's mind to his human body via a backup copy, but they were unable to relocate the captured Chase in his Holon.

Over the next four years, Julain's mind was altered and manipulated by the Union into believing that the Polity had betrayed him, transforming him into an agent of the Union. They subsequently modified and advanced his Holon body, making it larger, adding extra arms, and giving it control over Nanotech.

The Union finally releases their altered Julian Chase Holon by attacking one of the main server centers for The Ether, a massive online virtual reality game system. When the Vanguard and the gen:LOCK 1 Team arrive, the Union Holon attacks and severely injures Cameron MacCloud and fights with Nanotech. The unit flees when reinforcements arrive, but the Polity forces retreat from this unknown enemy.

Later, the Vanguard decide to attack a Union manufacturing plant and save Polity POWs. While they succeed, the Union Holon attacks them as they escape, easily overpowering the gen:LOCK team. A few manage to hit it, only to be stunned when fellow member Julian Chase's voice comes out of it. The Vanguard manage to fight the Holon off and force it to retreat, though everyone is left stunned and untrustworthy of Chase.

Back at the Anvil, Julian Chase approaches Dr. Weller and demands an explanation, to which Dr. Weller reveals that he is the second copy of the real Julian Chase's mind, and the first copy and its Holon was captured by the Union. Dr. Weller explains that the Union Holon is Chase, corrupted by the Union, dubbing it his "Nemesis".

Just then, the Anvil is attacked by the Union, with Nemesis leading the charge. Dr. Weller attempts to reach out to Nemesis and appeal to Chase's mind, but Nemesis is furious and tells them that they betrayed him, ordering them to kill "the copy" (the heroic copy of Chase's mind). The heroic Julian attacks Nemesis, and he literally does battle with himself as the Vanguard and gen:LOCK 1 fight the Union forces. The Union eventually breaches the Anvil, forcing gen:LOCK 1 to retreat back to their human bodies to escape, taking Julian's damaged human body with them as he continues to fight Nemesis.

As they are escaping, Nemesis sees the team with his human body and attempts to stop them, though Chase holds him off. As he begins to overpower Nemesis, the Union launches missiles from one of their Behemoths at the Anvil control tower, and Chase abandons his fight with Nemesis to save it. The Vanguard strikes down the Behemoth, only to discover it was filled with Nanotech, which gets loose and eradicates all exposed people in the Anvil. In the chaos, Nemesis escapes.

Personality
Nemesis is the original digital version of Julian Chase's mind, meaning he has the same determination, strategy, and drive as his true self. However, after brainwashing and manipulation by the Union, he believes the Polity to be traitors and seeks revenge on them. He is a dark version of the true Chase (ironic as he is the true Chase in a digital form inhabiting a mechanical body), and is the result of Chase being allied with the Union as opposed to the Polity. Because of his different allegiance, he is far more violent and wrathful than what he was originally like, and what the copy Chase continues to be.
