Must Read: Planet Hulk Must-read graphic novels are futuristic classics that shouldn't be missed. Of course, not every must-see is perfect. That's why we've rated them 1-5 on the patented "crunchy goodness" scale.

Title: Hulk: Planet Hulk
Date: 2006-2007

Vitals: Four of the Earth's top Super-heroes decide the Incredible Hulk's all-smashing rage could one day wreck everything. (Maybe because every single story about a future Hulk shows him either ruling the world, or surviving after humanity has become extinct?) So they shoot the Hulk off into space, and he goes off course, landing on the savage world of Sakaar. The planet's cruel, corrupt imperial government enslaves the Hulk and turns him into a gladiator — and transforms his customary rampage into something like justice.

Famous names: Greg Pak, Carlo Pagulayan, Aaron Lopresti, Gary Frank

Crunchy goodness: 5

Sequels: World War Hulk, in which the Hulk comes back to Earth with an alien army and vengeance in mind.

Elevator pitch: It's just like Spartacus — except this time nobody has to ask which one he is.

The shit: Pak and his collaborators put in major overtime on the world-building, creating an incredibly complex society with tons of alien races, not to mention the rampaging robotic wildebots. But what really makes Planet Hulk unforgettable is the Hulk's insect sidekick Miek, who evolves from scared larva to giant bug king to grief-stricken widower. Most comic book characters don't get that much development in twenty years.
