Incredible Hulk #271 (1982)
Wal Rus, and on one occasion, the incredible Hulk. Devoted to their last spark, the Killer Clowns gave their all and exterminated their targets with disturbing glee, but after the dread Toy War between their master and Lord Dyvyne, the futures of the Killer Clowns looked bleak. With their master defeated, and creator reformed, the cosmos may never see another Killer Clown again. However, some could have escaped to roam the universe with thoughts of murder still on their minds.
