Doctor Who Saves Spider-Man
Nothing good can happen when Superior Spider-Man and Spider-Man 2099 cross paths in space and time in Superior Spider-Man #19. It triggers a series of events that create a literal time bomb!

Spider-Man is lost in time but Grady Scraps saves him. He simply has to “reverse the polarity of the neutron flow” a Doctor Who quote made famous by Jon Pertwee in “The Sea Devils” (1972) and “The Five Doctors” (1983).

“You haven’t heard the last of Doctor–” says Superior Spider-Man upon returning. He’s referring to himself, Doctor Octopus who transferred minds with Spider-Man, but it’s clearly another Doctor Who reference. There’s even a dubious “What?!” You can almost hear the Tenth Doctor.
