Middletown

Middletown was a small town located in the U.S. state of Arizona. The megalamaniacal super-villain, The Leader, planted a bomb in the center of the town, and challenged the Hulk into locating the bomb and deactivating it. This was during a time when the Hulk was in his grey phase, which afforded him greater intellect. During this incident, the Hulk fought up against Redeemer and Rock in Middletown. The Leader detonated the bomb, killing most of 4,917 population. Those who survived were mutated into hideous creatures. Middletown then became known as Gammatown.
