I'd like to think that a zombie Iron Man, retaining at least some small part of Tony Stark, would shamble around searching liquour cabinets and bars. Any brains or human flesh he'd find there would be just a bonus.
These images are the work of cosplay photographer Adam Jay, while the man—or what remains of a man—inside the suit is Kyosti Kallio.
