The notorious Green Goblin joined forces with his longtime enemy Spider-Man to prevent a break-in at the Osborn Chemical Company by the albino ganglord known as Tombstone. The Goblin who is secretly Harry Osborn, owner of the company, was also aided by his brother-in-law, the one time super villain called the Molten Man. The trio succeeded in defeating Tombstone, who was attempting to steal a dangerous new chemical called Diox-3. In the ensuing battle, however, Tombstone was accidentally exposed to the substance and gained super-human strength and durability. These new powers enabled Tombstone to escape.
