One thing Marvel takes great pleasure in is reminding readers of the controversial Spider-Man story arc "One More Day." Though the events angered a segment of fans by dissolving Peter Parker's marriage to Mary Jane Watson, it also helped kickstart a new era for the wall-crawler that continues to this day.
If there's one series where "One More Day" is constantly alluded to, its Spider-Man/Deadpool. The comic brought Peter Parker face-to-face with Mephisto, who Peter originally made a deal with that resulted in the disappearance of his marriage, along with his identity as a hero being a secret once again.
"One More Day" rears its ugly head yet again in Spider-Man/Deadpool #33. After Old Man Wade Wilson of the future switches places with the present-day Deadpool, he becomes captured and tied up to Spider-Man. An older, gray-haired Deadpool is just as talkative as his younger counterpart, so he begins chatting up Spider-Man, calling the hero by his public last name. Of course, in the future, Wade is aware of who Spider-Man really is. However, "One More Day" reversed Spider-Man's public unmasking, so there's no way Wade should know that Peter and Spider-Man are one and the same. This leads to a slightly awkward moment of fourth-wall breaking.
"I vaguely remember this happening," Deadpool said while staring directly at the reader. "I mean, how could you forget..."
Spider-Man and Deadpool have what you could consider a "complicated" relationship. Wade may wear on Peter's nerves, but the two make a pretty good team. Deadpool has just the right amount of humor where he can get away with poking fun at his best bud and "One More Day."
However, one can argue with Spider-Man/Deadpool and Amazing Spider-Man, Marvel needs to either undo "One More Day" or stop trolling Spider-Man fans with constant reminders. Perhaps we'll get a definitive answer once Amazing Spider-Man relaunches with the new creative team of Nick Spencer and Ryan Ottley for Marvel's "Fresh Start" publishing initiative.
