Noiman Cascade is a villain from Contra Hard Corps. A famed mercenary and skilled hacker, Noiman was hired by Colonel Bahamut to invade the systems of the laboratory where the government kept the Alien Cell retrieved after the Alien Wars and to cause mayhem by hacking various unmanned robots in order to avert attention from the Hard Corps.

After the Alien Cell is stolen from the laboratory, the Hard Corps are sent to find Noiman on his hideout, located on a garbage dump. Upon being found, Noiman creates various holograms for the heroes to fight, but he eventually surrenders after they are destroyed, claiming he was only working for money. Upon being interrogated, he reveals that Colonel Bahamut was the mastermind all along.
