Spider-Man Vol 1 #22

Revenge of the Sinister Six Part 5 of 6.

"The Sixth Member" Guest-starring the Hulk, Ghost Rider, and Sleepwalker. 

The Sinister Six has returned to Earth's dimension...and they have a new partner to replace the Sandman! It's Gog -- the creature Spider-Man battled in the Savage Land way back in Amazing Spider-Man 104. Why did Doc Ock put him on the team? Because Gog will be needed for the Sinister Six's attack on Hydra's satellite control center! Once the Sinister Six begin their assault, a new team of heroes assembles to challenge them: Spider-Man, Ghost Rider, Sleepwalker, and the Hulk! Can this unlikely quartet derail Dr. Octopus' dream of world domination?

Appearances by Electro, Hobgoblin, Mysterio, and the Vulture.

Cameo appearances by Mary Jane Watson, Deathlok, Solo, and the Sandman
