Spider-Man Vol 1 #48

Beware the Rage of a Desperate Man Part 3 of 4.

"Demons of Our Pasts" 

At the Kravinoff estate in the Ural Mountains, the Hobgoblin and Kraven's son strike a deal! Jason Macendale will receive super-strength in exchange for Kraven's journal. And once the procedure is over, the Hobgoblin makes a beeline back to the United States -- where of course the Demogoblin is waiting! Inside a house of worship, the Hobgoblin and the Demogoblin do battle again! And this time one of them will not walk away from the fight -- despite the best efforts of your friendly neighborhood Spider-Man.

Final appearance of the Demogoblin.

Cameo appearances by Ben Reilly (aka the Spider-Clone), Mary Jane Watson, and Gregor.
