Adewale Akinnuoye-Agbaje as Killer Croc

Waylon Jones was afflicted with a skin disorder that gave him reptilian features and crocodilian appetites, turning him into the cannibalistic Killer Croc. Akinnuoye-Agbaje is truly unrecognizable under the heavy makeup that requires more than four hours to apply.

Game of Thrones fans may remember him appearing in a Season 5 episode as Malko, the captain of the slaver ship that captures Tyrion Lannister and Jorah Mormont.
