[Earth-616 Deadpool and Wolverine] are the only versions of the characters that constantly fight one another and can never put their differences aside.
Atleza’s explanation inWeapon X-Traction"Part Seven" ultimately shows that despite the MCU’s happy ending for Deadpool and Wolverine – as they sit on the couch together with the friends they made in the Void –there was never truly a chance that the story would go any differently. The two were always bound to come together in times of crisis because they share too much in common to be mad at each other.In fact, Atleza mentions that it’s their similarities that make them best friends, because they’re both “functionally immortal” and got their abilities “from the Canadian government.”

However, there’s only one exception to the rule:Earth-616’s main continuityDeadpool and Wolverine. Atleza brings up that out of every variant of the two she’s seen, they are the only versions of the characters that constantly fight one another and can never put their differences aside. It’s the very reason why she sends them onWeapon X-Traction’s grand multiverse adventure in the first place, as she works to ensure they become friends. Meanwhile, the MCU, which has beendescribed as Earth-199999despite beingdeemed by in-universe characters as Earth-616, finds Deadpool and Wolverine succumbing to their cosmic fate.
Despite how creepy it sounds that they have no choice in the matter, Deadpool and Wolverine eventually befriending each other in the film may have saved their lives.

The Mainstream Marvel Versions Remain At Odds
Despite how creepy it sounds that they have no choice in the matter, Deadpool and Wolverine eventually befriending each other in the film may have saved their lives. During the movie’s climax, Deadpool attempts to sacrifice himself by overcharging the Time Ripperto stop Cassandra Nova. However, Wolverine comes in at the last second to complete the connection, and the two survive by working together. Had their destined friendship not been pre-determined by the multiverse, Wolverine could have left Deadpool to die. However, he joins him in the last moment, cementing their friendship and ensuring their survival overall.
In the end,Ryan Reynolds and Hugh Jackman’s takes on the charactersowe a lot to this massive reveal behind their fate in the multiverse. Without the pre-written rule that Deadpools and Wolverines are always bound to become friends in the end, Deadpool would have either sacrificed himself or failed to stop Nova from destroying the multiverse. However, it still comes off as a little creepy, andMarvel’soverall answer to their multiversal friendship ultimately givesDeadpool & Wolverine’s ending a darker meaning.
