The Team-Up of Deadpool and Spider-Man can fit the actual origin of Venom in Avengers: Secret Wars.
In the well-known 1985 Marvel Comics plot Secret Wars, Spider-Man looks for a new suit after his original one gets destroyed in fight. He discovers a symbiote that decides Peter Parker as its host after turning into a black suit. This marks the first-ever appearance of Venom in Marvel Comics and the classic black suit of Spider-Man. But the 2015 Secret Wars offshoot Deadpool's Secret Secret Wars reveals Wade Wilson also attended the event and connected with the symbiote before Spider-man was erased from every other character's memories.
Likewise, Avengers: Secret Wars might see the symbiote Tom Hardy's Eddie Brock returned left behind in the post-credits sequence of Spider-Man: No Way Home. The symbiote could locate Deadpool first and link to him while searching for Spider-man, therefore persuading him to locate the Peter Parker that Venom identified in Venom: Let There Be Carnage. Deadpool might deliver the symbiote onto Spider-Man following a brief fight side by side or against each other, producing Spidey's black outfit and the Venom for the MCU.
Venom is the ideal character to unite Deadpool and Spider-Man in Avengers: Secret Wars.
The post-credits symbiote of Spider-Man: No Way Home would be among the fastest and most natural means to unite Spider-Man and Deadpool. There will probably be hundreds of characters from all throughout the MCU jammed into Avengers: Secret Wars, therefore justifying each individual team-up can take up a lot of screen time. Apart from honoring the source material, a reinterpretation of Deadpool's role in Deadpool's Secret Secret Wars and Spider-Man's first meeting with the symbiote in 1985's Secret Wars would pay off the confusing Venom tease from Spider-Man: No Way Home's post-credits sequence.
Deadpool is the only MCU character other than Spider-Man that would be an excellent Venom host. Both of them are related to a higher multiversal awareness; venom's graphic character fits exactly with Deadpool's violent proclivities. Once Deadpool arrives in the MCU's Earth-616 following the events of Deadpool & Wolverine, Deadpool's self-aware mind could be the perfect source of information that could point Peter Parker's location even if the symbiote left behind by Eddie Brock could still carry the wish to bond with Tom Holland's Spider-Man.
The dynamics of Deadpool and Spider-Man would change Deadpool's part in the Original Secret Wars published in Marvel Comics.
According to the original Secret Wars and Deadpool's Secret Secret Wars, both Spider-Man and Deadpool participated in the 1985 event. Unfortunately for Wade Wilson, though, Deadpool's participation in the fight was erased from everyone else's memory when Wasp yearned to forget her brief affair with him. This is analogous to the dilemma Tom Holland's Peter Parker discovers following the conclusion of Spider-Man: No Way Home, whereby Doctor Strange's curse removes Peter from the memory of the whole planet.
Apart from sharing the symbiote, Deadpool and Spider-Man can develop friendship over their comparable circumstances. Both Spider-Man and Deadpool can meet their new friend in one another; none of them have pals or acquaintances in the MCU. Their first meeting in the MCU might result in a full-fledged Team-Up in a future MCU film with additional heroes like Daredevil and the Punisher as well as Venom as an antagonist, either for Spider-Man 4 or Deadpool 4.
Deadpool is the ideal link between the new symbol of the MCU and Eddie Brock's Venom.
It has been announced that The Last Dance by Sony is the last Venom entry in their Spider-Man Universe. That does not imply Venom will die or retire permanently though. At least his progeny, venom could find new hosts in the MCU including Spider-Man. Should Deadpool be the first one to discover the Symbiote, his "Venomized" demeanor will enable viewers to become acquainted with the concept of hosts unlike Tom Hardy's Eddie Brock.
Other characters who might be the symbiote's hosts in the MCU include Mac Gargan, last seen in Spider-Man: Homecoming's post-credits scene teasing a vengeance against Spider-Man; Flash Thompson, who becomes Agent Venom and joins the Secret Avengers and the Guardians of the Galaxy in the comics; and Lee Price, who succeeded Gargan and Thompson with more brutality than both of them combined. Thanks to Deadpool's involvement in Avengers: Secret Wars, which mirrors in the comics, Spider-Man: No Way Home's symbiote will have gone through numerous hosts by the time Venom turns into Spider-Man's antagonist in the MCU.
Deadpool, Spider-Man, and Venom: The MCU's future
With fresh heroes, villains, and narratives constantly added, the Marvel Cinematic Universe is getting more and more expansive. Since Deadpool & Wolverine will be the first time R-rated characters are included into the main storyline, its forthcoming premiere marks a major change in the MCU. Particularly with his possible interaction with Spider-Man and Venom, Deadpool's existence in the MCU opens up a universe of opportunities.
Venom and his symbiote offspring's arrival into the MCU has produced an exciting new dynamic with possibilities for some spectacular conflicts and unanticipated partnerships. With its huge scale and multiverse consequences, the forthcoming Avengers: Secret Wars offers Deadpool and Spider-Man the ideal chance to link up and face their shared past with the symbiote. As Marvel Studios keeps investigating the great possibilities of its characters and narratives, the MCU seems to have a more fascinating future.
