Penguin

Bio
Oswald Cobblepot is one of the most powerful men in the Gotham Underbelly. He is a gang leader, and is also rich, owning the Iceberg Lounge club. His family was one of the founding families of Gotham, but lost their fortune. He blames the Waynes for that, so he is a unique villain in that he despises both Bruce Wayne and Batman for unrelated reasons.
