Princess Bubblegum was the first mutation, a scientist accidentally mutating herself during an experiment.

The Mushroom War is not a real event, simply something Princess Bonnibel Bubblegum came up with to explain the crater in the Earth. So I did some more digging and found out some info about our favorite cartoon. Okie-dokie-lokie, thanks for putting up with me for this long, bye!

Both of those theories fit this evidence. Don't kill me for adding this, but Finn could also be dreaming, and is simply asleep. (Yes that was a Gravity Falls reference.) Because of these small, but key pieces of evidence, it leads me to believe that this is the most plausible theory of Adventure Time. Prismo cannot possibly be a mutatation, as he is best classified as a being of pure energy with no weakness. Is he even a life form, or just a spiritual being? Prismo is rarely even in the show, but as with Shoko, the most important characters are often the lamest. Prismo is a being of an undetermined rank and an unknown type of life form. You all know him, if you're smart you hate him. Also, some of the "mutated" humans cannot possibly ever truly be a mutation. The apocalypse never really happened in Adventure Time, it was simply dreamed up by a boy with a wild imagination, and who went through something awful. And that proves that a pre-teen is dreaming up the Land of Ooo, and that Finn is in a coma. All of the things that Pendelton Ward thought we couldn't figure out, we did. It fits with the second most popular theory. How does this fit in with the theory that Adventure Time is post-apocalypse? It doesn't. If Shoko was around after the bombing, born as a humanoid, then how can Finn be her incarnation? Humans were extinct, yet Finn was born supposedly as a 100% human. Okay, what does that mean? Well, it actually means a lot. So we know that Shoko was around after the Mushroom War. If you haven't seen "The Vault" it's the episode where Shoko appears, and we learn about her backstory. I've been doing some reading, and the most popular theory is that Adventure Time is set in a post-apocalyptic Earth, with all humans either being mutated or killed off due to the detonation of the Mushroom Bomb. If the two are connected perhaps Bravest Warriors will explain how the Mushroom War starts on Earth and then leads to Adventure Time?Īlright. It looks almost exactly like the Earth in Adventure Time. It's also possible that Bravest Warriors (a cartoon by the creator of Adventure Time) and Adventure Time are connected in some way, considering that Chris, when looking into the future, saw a quick image of the Earth with a chunk of it missing. She states that the world would have been annihilated if Simon had not Marceline suggests that the mushroom bomb likely concluded the war as Some destruction, without the detonation of the mushroom bomb, Mushroom bomb and freezes the entire Earth in the process. Is transported to a world where Simon sacrifices himself to stop the Human" and "Jake the Dog" when Finn wishes the Lich, a product of the This is evident from the episodes "Finn the The war likely ended when the mushroom bomb was dropped along with the This was shown in the season 5 stories Finn the Human and Jake the Dog where they wished that the Lich never existed. The relevant information was that there was a single bomb that was supposed to end the war, the giant bomb that Simon (aka Ice King) stopped using his ice powers.

It's never directly explained what caused the Great Mushroom War, and nobody knows if they will ever reveal why there was a war in the first place, considering the show takes place 1,000 years after that took place.
