If the Wolverine of Earth-10005(B) is an Anchor Being, that would imply that had something to do with the Nexus event that created that branched reality.

What do you think was Wolverine’s nexus event?

Keep in mind that is will likely never actually occur in the movie, (as with No Way Home, there's a ton of spectulation on what's going to be in Deadpool 3), yet we still want to believe.

As Deadpool is seen traveling in the Nexus of All Realities with Wolverine, they overhear Doctor Strange explaning the concept of the multiverse to Spider-Man. As the two of them look around in the Nexus of All Realities, a blue blur suddenly runs across them and continues running in various directions. A rift opens and it is revealed to be Pietro Maximoff. (the MCU version, not the Fox version) Pietro manages to knock out both Deadpool and Wolverine from the Nexus of All Realities and the latter two end up in Hell's Kitchen in the Daredevil (2003) universe. As both of them are groaning, (with Deadpool swearing at Quicksilver for knocking them out) Elektra Natchios appears and looks at the two of them. As Wade and Logan get back up, they are approached by Elektra and asks where they came from. Wade then says hello to Elektra but calls her "Jennifer Garner" which angers Elektra. Logan then tells Elektra that Wade is just being an ******* and that he does this sort of stuff all of the time. Elektra then proceeds to tell them where they came from as they just appeared out of nowhere. When Wade asks where they are to Elektra, the latter tells them that they are in Hell's Kitchen in New York City much to Wade's dismay. Wade then tells Logan that they are in the wrong universe and that they must once again reach the Nexus of All Realities and travel to the MCU to which Logan undeniably agrees and leaves Elektra confused. As Wade activates Cable's Time Travel Device and (again) messes around with it in order for them to reach the Nexus of All Realities, the device pulls both Wade and Logan to the former. Now back again in the Nexus of All Realities, the two mutants look around and see various different earths around them. Several rifts open to reveal other Marvel characters from several Pre-MCU movies such as both versions of the Fantastic Four (the 2005 team and the 2015 team), Thomas Jane the Punisher, Nicolas Cage Ghost Rider, Wesley Snipes Blade, Eric Bana Hulk and Doug Jones/Laurence Fishburne Silver Surfer. Deadpool wonders where the **** are the X-Men in the rifts as all they see are a bunch of "non-mutant superheroes." The voices then come back and overwhelm Wade and Logan. The voices are Willem Dafoe Norman Osborn/Green Goblin, Campbell Scott Richard Parker, Toby Kebbell Doctor Doom, Reg E. Cathey Franklin Storm, Alfred Molina Doctor Octopus and Michelle Williams Anne Weying. Deadpool then gets even more ****** as he tells Wolverine that this is all his fault and they should have stayed in the Fox X-Men universe and not have left the former so that they wouldn't have gotten lost in the first place. Wolverine however doesn't seem to insulted and tells Deadpool that it's his fault for making them get lost in the first place, not him. The two of them begin attacking each other, however at the same time, the two of them begin to fall out of the Nexus of All Realities once more and the two of them end up in another universe where they meet a samurai-variant of Deadpool.

Deadpool 3 will probably only feature cameos from the Fox Marvel Universe, and (probably) not from other Marvel Universes such as the Sony ones and ones made by other studios such as Universal, New Line Cinema, Lionsgate and Colombia Pictures. They could potentially appear in Avengers: The Kang Dynasty and/or Avengers: Secret Wars.
