History
Monument Valley was located on the Utah-Arizona border. Red Hulk landed here from the Moon,[1] and was then beaten by Hulk, A-Bomb, and Thor.[2]
Hulk was later recruited by the Grandmaster to fight with the other Defenders against the Red Hulk's Offenders.[3] Each member was sent to different places unfamiliar to them to face their arch nemesis.[4] The contest ended when the Red Hulk returned to the Monument Valley, after killing all the Defenders and Offenders.[5]
