Ranken (Earth-4678)

"You fail to see the bigger picture, Batman. My work was about protecting this country. You care more about those animals-Are you crazy?! You can't put me next to that monster! Let me out of here!"

- Warden Ranken

Ranken was the corrupt warden of the prison airship Iron Heights Penitentiary. Working under Quorum, he performed unethical experiments upon the prison's inmates, notably Killer Croc, in the hopes of weaponizing his mutation.
