The One-Eyed Penguin is a childhood friend of the Penguin Kurgan. He lost his eye during his first battle fighting alongside his friend. The Penguin Kurgan felt so guilty (as he was the one who started the fight) that he often listens to the One-Eyed Penguin's reason. It was the One-Eyed Penguin who convinced the Penguin Kurgan to join forces with the Emperor Penguin.
