Batman: Arkham Knight - 10 Villains We Want To See

9. Killer Croc

After only making a cameo in Arkham City and a fleeting appearance in Origins, it's time for Killer Croc to once again become the massively intimidating monster he was in Arkham Asylum. I still remember the tension I felt in that section as I walked carefully along the planks of Croc's sewer, trying to stop the massive mutant from erupting from the waters and ripping me limb from limb. Given Rocksteady's track-record of making awesome boss fights, I'm confident that lightning could easily strike twice and they can deliver an experience just as memorable as the first time around. There's still unresolved conflict between our Bats and Croc, and this is the perfect time to relive it once more. For extra effect, why not have a massively tense section where Batman is being affected by Scarecrow's fear gas and must engage Killer Croc while battling his nightmares?
