Oswald Cobblepot aka The Penguin will be another main antagonist that will pose a big threat towards The Batman and the rest of the GCPD. He is the kingpin of Gotham. He has control over an underground society and has big plans for this city. He is also running for mayor for Gotham, which might seem impossible due to him having control over the corruption that plagues the city. However, he can easily become mayor with just how powerful he is.
