Mushroom Kingdom Theory
I'm Sorry, What?
Oh, yeah, you heard me right. The Mushroom Kingdom is the absolute center of EVERYTHING. I know that sounds outlandish, farfetched and even insane, but I am so ready to prove everything you know as false. So buckle up for a journey that's gonna take you to (not literally) every single corner of the multiverse and beyond.
We all (at least most of us) know that Mario first appeared as Jumpman in the original Donkey Kong video game back in 1981, and he wasn't rescuing Princess Peach, but instead his (at the time) girlfriend, Pauline. So, turns out, Mario originates from a Donkey Kong game, however, the number of times that the character of Donkey Kong has appeared in a Super Mario game vs the number of times where Mario appears in a Donkey Kong game leads me to believe that Donkey Kong actually exists in the Mushroom Kingdom's reality.
That being said, it would stand to reason that any characters introduced in one of Donkey's games also exist within this same world. Including two characters named Conker and Banjo-Kazooie. So...
Diddy Kong Racing
One of the (actually well-received) spin-off of the Donkey Kong series was not only the first racing game in the franchise, but also the first on the Nintendo 64. Diddy Kong Racing was a surprising success for the franchise and introduced several brand new characters to gamers: Pipsy the Mouse, Timber the Tiger, Krunch the Crocodile, Drumstick the Chicken, T.T. the...Timer(? beats me), and of course the two characters that got their own gaming franchises, Banjo-Kazooie and Conker the Squirrel. Two other characters got their start in Diddy Kong Racing, but also made appearences in Conker and Banjo-Kazooie's games. Tiptup the Turtle was later used in Banjo-Kazooie during a mini-game, and Bumper the Badger was in jail during Conker: Live & Reloaded.
Now that's pretty awesome that we got those two new games from a racing game, especially when you consider that means they are part of the Donkey Kong mythos, and in turn, the Mario Bros mythos. But, lets dig a bit deeper, shall we?
Conker's Bad Fur Day
Since that's where Banjo-Kazooie's involvement in the bigger picture stuff, I'm going to focus my attention now over to Conker's Bad Fur Day. Why, you ask? How could a cartoonish red squirrel possibly have a bigger picture connection? Well, sit back and buckle your seatbelt, kiddo. It's about to take off.
In his game, Conker takes journey to get home, but accidentally usurps the Panther King and becomes the new ruler. In the final boss battle, Professor von Kripplespac releases a xenomorph. Yes, an actual XENOMORPH. They don't even pretend it's not a xenomorph.
So, keeping that in mind, that means that the Xenomorphs exist within the Mushroom Kingdom universe as well, which means that ANYTHING that has crossed paths with the Xenomorphs also exist within the Mushroom Kingdom. Shall we go down the list? Of course not, but let's just say because of the Batman/Alien crossover, that adds the DC Universe to the Mushroom Kingdom as well. And of course, nobody can forget the Aliens vs Predator movies. Which brings us to my next point...
Archie vs Predator
Yep, you read that right, Predator has met Archie and his pals. Which means that Archie comics also exist in the Mushroom Kingdom. Well, Archie has also crossed over with the Punisher (crazy, I know), which now connects the Marvel Universe to everything else too. And since Marvel publishes pretty much anything owned by Disney or Lucas Films, we can include Darth Vader, Baymax and Rapunzel to the mix of this massive, fungus filled world that we now all will call home.
That not good enough for you? Mike Tyson's Punch-Out has Mario as the referee, which means that Mike Tyson lives in the Mushroom Kingdom. And he lives in the real world. Which means that the real world exists in the Mushroom Kingdom.
Still not convinced?
Filling in the Gaps
As mentioned before, Marvel publishes almost everything from Lucas Films. But IDW does the majority of the children's comic series for Lucas Films. Also, IDW does the current run of the TMNT. Which has interacted with the Ghostbusters on multiple occasions. Also, they've met Batman. Of course, Batman exists within the same realm as the Green Lantern Corps, who have had crossovers with both Star Trek and Planet of the Apes.
The crew of both Star Trek and Star Trek: The Next Generation have had run-ins with the X-Men. The crew of the USS Enterprise has also met up with Doctor Who, the Legion of Superheroes, the Planet of the Apes, and the Xenomorphs of the Alien franchise (geez, these guys are everywhere!). Guys, it's not just a linear connection, there is a massive web of reality, that somehow the Mushroom Kingdom is at the very center of.
This is HUGE. Why have we not already addressed this on a more mainstream scale? Let me know if there are any characters or series that you'd like me to connect, just so I can prove you wrong. I love a good challenge.
