Wade Wilson takes us back to 1984, before his own origin story in 1991, all the way to the Beyonder’s Battle World where he inserts himself into the original Secret Wars story. I feel like the story would be less impactful if you haven’t read the original Secret Wars, so definitely do that.
Is it canon? Like, did it really happen? (As much as a comic book can really happen.) There are some clues that it did, but there are also elements that point to wacky Deadpool having fun and breaking the fourth wall. One piece of evidence that took me out of the story was Absorbing Man. His power (at the time of Secret Wars) is the ability to touch a substance and gain the properties of that substance, For example; if he touched steel, he would turn to steel but also gain the resistance and strength of steel. But Crusher Creel (Absorbing Man) touches DP and gains his physical attributes and power, much like Rogue’s power absorption. Was this a clue that the story didn’t really happen, creative liberty, or just a writing/continuity error?
Deadpool’s Secret, Secret Wars is full of nostalgia while at the same time adding DP to the original story in a fun, and sometimes, touching way.
Good touching, not bad touching.
