JSA: The World Wikia

Mr. Wilcox is a minor character that appears in Saturday's Rise, as the enraged, cruel boss who fired his ex-intern Chris Russo. He even takes a few moments to lash out at both Justin and Isaac, telling them to leave the Wilcox Corporation, if they didn't have any business with them. After finally getting his ex-employee to snap, Chris Russo hires The Mubarak to exterminate Mr. Wilcox. The next day involves a climatic battle between the Wilcox Corporation, local authorities and The Mubarak, which ends with The Mubarak winning hands down. The Mubarak basically terrorized the corporation with their legion of pseudo and the entire catastrophe ended with Mr. Wilcox himself getting devoured by Silhouette, as his prized Genesis Software falls out of the window and lands on a conveniently placed bush for Justin to grab. That event is what triggered many things in Sunday's Fall.
