Title: The Death Of Superman
Vitals: The Superman story that helped launch a speculative bubble that almost made dot-com exuberance look rational by comparison. An alien monster is tearing everything up, so Superman punches it. And it punches him back. They punch each other a lot — until Superman... DIES!
Famous names: Dan Jurgens, Roger Stern, Louise Simonson
Crunchy goodness: 2
Spinoffs/Sequels/Copycats: After millions of people bought Superman #75 thinking it would some day become incredibly valuable (ha), tons of other superheroes "died" or became paralyzed or turned out to be clones. More recently, animation diva Bruce Timm put out a straight-to-DVD adaptation called Superman: Doomsday.
Elevator pitch: What if someone punched Superman really really really REALLY hard?? No, no, harder than that. A whole bunch of times. What then?
Deadliest spoiler: Superman comes back from the dead, but he pays a terrible price. He's stuck with a disfiguring mullet.
