Guys hear me out I have an actual game theory that will blow your socks off
Look at the image above. What if I told you that he is the actual Mario. If you’ve ever played super Mario odyssey you will know that when cappy possesses something it gives the possessed thing “Mario’s” signature hat and mustache. My theory is that they aren’t actually Mario’s hat and mustache, they are Cappy’s. For you see, Cappy is the actual guy who has the M cap and mustache and when he possesses something then it appears on them to show that it’s cappy. Here’s how I think the story went: Cappy was fighting Bowser whilst controlling Mario on the airship at the start of Mario odyssey. Then bowser kicked Mario off of the ship, separating Cappy from his host (Mario). Once detached from the Cappy parasite, Mario regains his former thoughts briefly and has no memory of Cappy as if he blinked and now he was here. Then he lands in Bonneton. This is when Cappy has to trick Mario into thinking he is a stranger so he can latch back onto Mario and possess him. You may be wondering: “how come Mario/Cappy can throw Cappy’s Cap and not lose possession of Mario?” Well in 2 player mode when in a capture, Cappy can fly around whilst Mario stays in control so the captured thing looks normal apart from mustache on it. That’s why I believe that as long as Mario has either the mustache or cap on him, he is still possessed.Cappy is not inherently bad. He takes control of Mario’s body to be able to do platforming and acrobatics. All this time, all the battles against bowser, all the Mariokart races, all the galaxies discovered. It’s been Cappy. The whole time. The Mario you see above is simply a host for the parasite. With Cappy’s signature hat and mustache that appear on every captured thing. This begs the question…
Who’s possessing Luigi??????
