Title: MARVEL FANFARE#29 (first story) by John Byrne (writer/artist)
Synopsis: the Hulk encounters an Indian chief in the desert, who manages to calm the Hulk's rag somewhat. Hulk is surprise attacked by Hammer and Anvil. The Indian chief shoots Hammer in the head with Scourge's trademark gun and declares, "Justice is Served!" With their life forces linked, Anvil dies as well.
Is is a key part of the overall Scourge storyline? No
Is it part of the first main story in this issue? Yes since the the only character in the story besides Hulk and the villains turns out to be Scourge
Comments: This is the only story to show the original Scourge doing something not part of his killing plan (trying to help the Hulk)
