Danton Black

Danton Black, nicknamed Captain Clone and later Multiplex by Cisco Ramon, was a bio-geneticist who specialized in therapeutic cloning, and was employed by Stagg Industries. He was a metahuman affected by the S.T.A.R. Labs particle accelerator.

Biography
Danton was an employee of Stagg Industries working on cellular regeneration in an attempt to save his dying wife Elizabeth, going as far as even testing it on himself. However, Simon Stagg later end up firing Danton and taking credit for his work. When the particle accelerator exploded, Danton was infected by dark matter released, awakening his ability to duplicate himself.

Danton, wanting revenge on Simon, robbed a gun store killing the clerk in the process. Paying off Stagg's chief of security, Java, Danton attacked Stagg during a university gathering honoring him. However, he missed Stagg by a few minutes. When he and his copies attempted to gun down a responding security guard, the latter was rescued by Barry Allen, allowing Black to escape. Later Danton talked to Java in an attempt to get him access to Stagg's house. However, he refused and punched Black when he threatened him. In anger, Black multiplied himself and beat him to death. Later, Danton tried to kill Stagg again at one of his factories but was once again foiled by Barry. As the two engaged, Black brutally beat Barry, prompting him to escape. Later Danton tried to kill Stagg at his office, however he was confronted by Barry again who managed to defeat him after discovering his prime self, and running him into a wall, knocking him out. Danton got up and attempted to attacked Barry again, only to crash through a window. Barry managed to catch him by the arm but Danton refused to be saved, and grew an extra arm to squeeze the Flash's arm, forcing him to let him go and thus Danton fell to his death despite Barry's efforts to save him.

Powers and Abilities

 * Cellular replication: Danton could replicate his cells at superhuman speeds allowing him to create life-sized clones of himself. He was shown to be able to create hundreds of clones before feeling the stress. He could also use this power to create multiple limbs on his body. He can also replicate anything he is wearing, but not weapons he carries, leading him to steal them.

Weaknesses

 * Fatigue: Despite the ability to create large amounts of duplicates of himself, it causes too much stress on his body, and, like Barry, he ("the prime") begins to feel the stress of it.
 * Hive mind: If Danton is knocked unconscious, a domino effect is created: his fellow clones also fall unconscious as he cannot give them commands.
