It's no more far-fetched than a magical concoction of psychedelic drugs that Crane shots in people's faces to make them go ape-****. Or like Wayne said, a dude who runs around with a bat mask and tight armor. Or a guy who dresses in purple suits and puts make-up on. Or a magical world-terrorist organization operation hell-bent on making an entire city go insane so it can be cleansed. It's...a...comic...book. You suspended belief before, just do it again.
