Chill Penguin

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. Possibly as a result, his defeat freezes the lava in the latter's stage, allowing X to walk over it with impunity.

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.
