Warning: contains spoilers for Miles Morales: Spider-Man #26!
Marvel may be about to repeat one of the most controversial Spider-Man twists ever with Miles Morales: the reveal that our hero is actually a clone of the original. The Clone Saga storyline of the '90s is infamous for its many twists, chief among them the reveal that the Peter Parker readers had been following for 30 years was not actually Peter, but a clone. Now all signs point to Marvel repeating their biggest '90s Spidey mistake - but with a notably different spin.
The Dark Age of comics in the '90s was filled with headline-grabbing events. Superman died, Green Lantern turned evil, aliens created a dozen new ridiculously edgy heroes to replace "lame" classic characters - the decade was full of twists and the Clone Saga was no different. Peter meets his clone (Ben Reilly), who proclaims that he is the original...and shockingly turns out to be correct. The intent was for Peter to marry Mary Jane and move on with his life while Ben became the new Spider-Man. Fans revolted, sales plummeted, and the ending was hastily rewritten to reveal that Peter was the original after all. Now a major clue dropped in Miles Morales: Spider-Man #26 points to Marvel recreating the same twist: that Miles Morales is and has always been a clone.
After Peter and Miles team up and escape from three Spider-Men (all of whom look eerily similar to Miles), Miles swings home to study for an exam and finds Ganke (a rift between them was capitalized on by one of the clones, who texted Ganke a threat). Miles needs to stay up, so he reaches for a surprised Ganke's soda. "You never drink soda!" Ganke says, to which Miles responds "Just need the sugar." responds Miles as he chugs it down. It's a small detail but an important beat for the writers to point out. Is Miles acting out of character because he's off-balance after confronting his clones...or is he not the Miles that Ganke knows? Peter Parker was shocked when he discovered he was the clone, but this is a new wrinkle in the story: Miles may be getting as many hints as the reader.
It's important to note that at the end of the issue, Miles stumbles upon a lab of sorts; he finds vials in a small centrifuge containing a green substance. Angered at the prospect of his enemies making more clones, Miles smashes all the vials, only to be surprised and tied up by the three clones who attacked him earlier. Their apparent leader is furious. "WHY DID YOU DESTROY OUR CURE!?" he shouts. Thus the pieces begin to come together for astute readers: Miles suddenly acting out of character, the other clones desperate for a "cure" of some kind...the odds are very good that Miles is a clone as well, and he's bound to discover this revelation soon.
Miles Morales is also one of the very few heroes who successfully transferred over from the Ultimate Marvel universe. Though a story was written to place him within the 616 continuity, a character originating from another universe is a good narrative excuse to bring up a past that Miles may not fully remember. In that case, when the secret behind Miles Morales' clones is revealed - the fact that he might be one of them - it won't come entirely out of left field, and in fact may actually be what Spider-Man fans have guessed all along.
