Walking with Superman: Day 306

The Key to Hell has been stolen! The ceremonial key to Hell, Michigan, that is. And a burglary this badly bungled could only have been conducted by the very worst: the World's Foulest duo of Bizarro and Batzarro! Superman's on their trail, if only to prevent them from stumbling their way into causing actual harm. Little does he know that, with this phony key, they've conjured up the very real--and very bizarre--demon, Nagirte! What terrible secret power lies within their demon ally? What strange god set the dimwitted duo on their quest in the first place? And will Superman be able to halt their hare-brained escapade with a straight face?
