The introduction of the Marvel Cinematic Universe's format has changed the cinematic world behind the screen into something all new. Many movie-goers are constantly thinking of how other films could introduce their own cinematic universe right along with big movie companies thinking of the same in order to compete with Marvel.

There has been a lot of fan talk about how the same could be done for Nintendo using a few of the video game movies that have and will hit theaters in order to craft a Super Smash Bros. cinematic universe. While these theories are mostly played for laughs, they're fun to think about.

10 Mario Will Bring The Cinematic Universe Together

Many fans have immediately came up with a little gag theory that the legendary videogame star, Mario, will appear in different upcoming videogame films to recruit the various gaming characters to something that they have dubbed the "Super Smash Bros. Initiative."

As Marvel Cinematic Universe fans know, this is the same way the MCU started coming together with Nick Fury appearing in various Marvel films at the end of the credits to recruit its heroes to the Avengers Initiative.

9 Mewtwo Will Be Able To Sense Other Universes

Many fans of Pokémon know that Mewtwo is one of the strongest psychic-type Pokémon there is. This was even shown in the first live-action Pokémon filmPokémon: Detective Pikachu.

Many theorists for the Super Smash Bros cinematic universe have theorized that this powerful psychic ability would play a huge part in the gathering of the Smash Brothers, with Mewtwo being able to sense the incoming challengers with his powerful psychic power.

8 Sonic's Rings

Sonic's rings are an obvious piece of the potential Super Smash Bros. movie gathering. Much like in the original Sonic the Hedgehog game, these rings are portals to other dimensions in the hit Sonic The Hedgehog movie.

This little reference to Sonic's first game and his many comic book appearances would play a big role in being the portals made to bring together the various videogame characters according to theorists. Plus, Sonic is no stranger to big stories.

7 Someone Will Invite Pikachu & Sonic

One hilarious theory is a part of the belief that Detective Pikachu and Sonic the Hedgehog will receive updated versions with all-new endings featuring a familiar overall-wearing plumber.

As the theory goes, Mario himself will appear in these ending and will ask the two personally for help, causing them to each join Smash. The rest of the characters will follow suit, joining in different ways.

6 Phase One Will Begin With Pikachu

Many theorists have said that the entire series will begin not with Mario in his upcoming Super Mario Bros. film from Illumination, but with Pikachu in Detective Pikachu.

It is unknown whether the Pikachu that fans theorize about will be the actual Pikachu or the Ryan Reynolds voiced Pikachu, but many think he will somehow kick things off.

5 It Will Begin With The New Mario Film

Most Super Smash fans believe that things would begin with the new Super Mario film before anything else. While it would be the first animated film in the cinematic universe, many believe that it would work best if Mario began the series, a theory that earns a little more credibility when one considers the fact that Nintendo seems so heavily involved in guiding that movie creatively.

4 The Connection With The New Solid Snake Film

Many thoughts have come up with the announcement of the new Metal Gear Solid film and its newly announced main actor— Oscar Isaac— and of course, some of those thoughts were cracks at a Smash cinematic universe.

While many fans doubt there would be any direct reference to such a thing in the first Metal Gear film, they do believe that somehow the film would play a new hand in birthing the villain of the crossover film.

3 Sonic's Speed Will Play A Hand In The Clash

Sonic's little tantrum seen in the Sonic the Hedgehog movie that caused him to power down an entire town is a big point in Smash cinema theories.

Many say that there is potential for Sonic to cause an even greater boom than someone like the Flash, attracting the attention of those from different worlds and even universes. This would play a large hand in bringing together the Smashers, solidifying Sonic as one of the most important characters of the crossover, despite him being a SEGA character.

2 The Actual Film Would Introduce Samus, Kirby, & Star Fox

While some theorists believe it would be a bad move to not introduce each character with their own film, others believe some should be introduced Black Widow and Hawkeye style with appearances in the actual Super Smash Bros. film and in other Nintendo films.

Three characters many mention in this way are Samus of the Metroid series, Kirby, and Fox McCloud of Star Fox. Each of these characters is space explorers, making them prime candidates to show up in spectacular fashion.

1 Robotnik/Eggman Would Cause the Crossover

One meddling character that many expect to play a big hand in the clash of the many videogame characters is Doctor Eggman, Sonic's archenemy.

Eggman, otherwise known as Dr. Ivo Robotnik, is no stranger to messing up multiverses and connecting dots best left unconnected, making him a prime candidate for this theorized role.
