Chill Penguin

Chill Penguin ("Icy Penguigo" in Japan) is one of the Mavericks from Mega Man X. He lives in the North Pole area (some walkthrough sites called it the "Snow Mountain" area), and most players tend to fight him first, as some see him as the easiest Maverick to defeat with the normal weapon. However, when faced later on in Sigma's Fortress (assuming you don't have the Hadoken Fireball), he is easily burnt with Fire Wave. Speed Burner works just as well against him in Mega Man Xtreme.
