Fictional character biography Randall Darby was discovered and recruited by Magneto to become a member of his Brotherhood of Evil Mutants, taking the code-name Shocker. After being abandoned by Magneto, Darby and his teammates came to be known as the Mutant Force. Under this name they work for the United States government, and, later, the Secret Empire. Darby changes his code-name to Paralyzer when the Mutant Force become the Resistants. The Resistants' protest against the United States' Mutant Registration Act was cut short by a clash with John Walker, who was the current Captain America. Later, the Resistants revert to their Mutant Force identities and costumes. Their next clash is with the New Warriors. Paralyzer later battles Spider-Man, subduing him with a lucky blow. Spider-Man later teams up with several members of the Midnight Sons who were investigating the activities of a more demonic Spidey-doppelganger. While pursuing this creature, the heroes discover and stop Paralyzer's plan to recreate Zzzax. After the Sentinels destroy Genosha, Paralyzer, again called the Shocker, helps Toad and other mutants create a statue of Genosha's former ruler Magneto. Unus becomes the leader of the group. Shocker is seen during a meeting of Unus' people, after Unus himself was swallowed by Freakshow, one of the other mutants on the island. Their group was not sure if they would take Unus back if, in fact, he had survived. He does return, prompting Shocker and the others into attacking him in order
