Spider-Man #21 (1992)
“Revenge of the Sinister Six: Part Four, Dealing Arms”
Writer: Erik Larsen
Artist: Erik Larsen
As he’s about to shoot Spider-Man (who he thinks is Dr. Octopus thanks to Mysterio), Solo starts taking fire from behind. Turns out to be Cyborg X (who Spider-Man and Ghost Rider were fighting in the first issue) and he takes the injured and unconscious Spider-Man to a government care facility where they patch up his suit and give him a robotic cast on his arm. Spidey leaves and runs into Deathlok, who wants to help him in exchange for going to the place where Spidey got patched up. They go to the Sinister Six hideout and find a portal to another dimension. They go through and Deathlok estimates 143,000 alien life forms have died. They leave and the building blows up. They go back to the lab where Spidey was patched up but just find a big pile of rubble, a bunch of dead and injured scientists, and the Sinister Six. The Sinister Six leaves in an airship and Spidey tags it with a tracer. Spidey returns home and collapses on the floor. MJ freaks out.
