5. The Penguin: Dan Fogler
The Penguin is a perennial Batman villain, and although Dan Fogler is a little young, I think that he is the only choice for this character. Fogler just has every physical attribute you would look for in The Penguin, and he is becoming a bigger star through every project. He may be a little too popular to do a CW show, but I thought the same thing about Ruby Rose, so we never know!
I want all the Batman villains to be part of the Batwoman series, even for Bruce Wayne to come back, also Commissioner Gordon, Barbara Gordon, Lucious Fox
