'Spider-Man: No Way Home' Teases the Sinister Six, but Will the Last Member Appear? (SPOILERS)

Spoiler alert: This article contains spoilers for Venom: Let There Be Carnage and Spider-Man: No Way Home.

For the entirety of 2021, many Marvel fans have anticipated the release of Spider-Man: No Way Home. Now that the film is finally out, fans are ready to see whether their best theories match up with the movie.

The flick takes place after Peter Parker's (Tom Holland) identity as Spider-Man was revealed by Mysterio at the end of Spider-Man: Far From Home. As a result, Peter's life changes overnight. He turns to Dr. Strange (Benedict Cumberbatch) to help repair the damage.

But once Dr. Strange performs the spell, something goes awry. The multiverse opens, allowing several iconic Spider-Man supervillains from alternate realities to arrive in the MCU.

Now that Peter is coming face to face with unfamiliar villains, what does this mean? Which villains are returning? Did the Sinister Six form in No Way Home? Let's find out!

Spider-Man: No Way Home marks the return of several enemies of the web-slinger, and we suspect the group will band together to form the Sinister Six.

The threequel sees five infamous supervillains from the Sony Spider-Man universe — Doc Ock (Alfred Molina), Green Goblin (Willem Dafoe), Sandman (Thomas Haden Church), Lizard (Rhys Ifans), and Electro (Jamie Foxx) — fighting our friendly neighborhood Spider-Man.

With just five villains in the superhero flick, fans were hoping to see the MCU version of the Sinister Six. In the Spider-Man comic books, the team has had an abundance of members throughout the years, meaning filmmakers had many options for No Way Home.

Many fans speculated that a sixth villain will arrive later in the film, which would lead to the formation of the Sinister Six. The top contenders from the MCU trilogy include Michael Keaton's Vulture and Jake Gyllenhaal's Mysterio.

We last saw Vulture in jail at the end of Spider-Man: Homecoming, and he actually keeps Spider-Man's identity a secret from Scorpion, another Spider-Man villain. Unless he has a massive issue with Peter, we don't see him returning for another fight.

Also, we still don't believe Mysterio died at the end of Spider-Man: Far From Home. He is a professional illusionist, and his supposed "death" occurred off-screen — suspicious much? Though there's a chance he's alive, we highly doubt he'll return; Mysterio caused enough damage when he revealed Spider-Man was Peter Parker.

This leaves us with one potential MCU debut: Venom. Thankfully, Sony and Marvel Studios made this possible — if you didn't know, the post-credits scene for Venom: Let There Be Carnage shows Tom Hardy's Eddie Brock and Venom experiencing effects from the multiverse.

Eddie and Venom go from chilling in a hotel room at night to lounging in another hotel room in a different tropical area, this time during the day. The two are clearly confused, so Eddie turns on the TV to figure out what's going on.

Once the small screen comes to life, a shot of Tom Holland's Peter Parker appears on the screen. Fans were immediately excited about the possibility of seeing Venom and Peter face off, but did that come to fruition in No Way Home?

Sadly, it looks like the Sinister Six was a great fan theory, but it didn't happen in this film. Venom did appear briefly in the mid-credits scene but was zapped back to his own universe, leaving behind a fragment that could become an MCU Venom character. However, Peter did not get the chance to face off with one of his most well-known foes this time around.

Spider-Man: No Way Home is in theaters beginning on Dec. 17, 2021.
