Chill Penguin, is one of the Mavericks from Mega Man X based on a penguin. He was a Maverick Hunter from the 13th Polar Region Unit. In the OVA The Day of Sigma, he moved to the 17th Elite Unit and was under Sigma's command. When the revolt started, it sounded fun for him, so he joined up to exit from his boring post on the South Pole. He didn't get along with Flame Mammoth.
