Chill Penguin, known in Japan as Icy Penguigo (アイシー・ペンギーゴ Aishī Pengīgo?), is one of the Mavericks from Mega Man X based on a penguin. He was a Maverick Hunter from the 13th Polar Region Unit. There was strong animosity between him and Flame Mammoth.
In the OVA, The Day of Σ, he moved to the 17th Elite Unit and was under Sigma's command. During this time, he also led a company within the Elite Unit called "Chill Penguin Company," identified by light blue armor-clad humanoid Reploids. When the revolt started, it sounded fun to him, so he joined up to leave his boring post at the South Pole.
In Mega Man Maverick Hunter X, he is voiced by Dean Galloway, the same voice actor of Dr. Wily in Mega Man Powered Up. Also, in this game it is implied that Chill Penguin's involvement in the rebellion was also in part due to his jealousy of X.
