The solicitation for Dan Slott, Christos Gage and Giuseppe Camuncoli's "Amazing Spider-Man" #20, a tie-in for "The Clone Conspiracy," a Spidey-centric event series also launching the same month, reads: "Death is no more, and DOCTOR OCTOPUS HAS RETURNED!!! How is he back? And what does he have to do with The Jackal?"

It's been a long time since we've seen Doctor Octopus in his original form. At the end of the long-running "Superior Spider-Man" storyline that saw Ock's consciousness take over Peter Parker's body, the character seemingly perished. In the latest run of "Amazing Spider-Man," however, it's been revealed that, unbeknownst to anyone but him, Ock's consciousness has been preserved inside a robot working for Parker Industries, referred to as the Living Brain. Trapped in his mechanical form, Otto has been up to his usual schemes, working as an agent inside Parker Industries and sending classified information to other villains.

It seems Ock will somehow make it back into his original body by the time "Amazing Spider-Man" #20 hits stands -- but exactly how he factors into the overarching "Clone Conspiracy" is still unclear at this point. The character did feature in a teaser back when the event was still called "Dead No More," so if you're looking for clues, be sure to check that out.
