Throughout Adventure, many things will not be clear. Please post any theories you have concerning the show.

  • Due to Princess Bubblegum stating that she has an Uncle Gumball, as said in the episode Susan Strong, this could possibly mean that her gender swapped version (Prince Gumball) is her uncle, and that Fionna (Finn's gender swapped character) is his mother that disapeared due to some sea related way, thus Finn's fear of the ocean.

That actually makes alot of sense, what if and bear with me now. Before the mushroom war all the surviors went underground to avoid the nuclear holocaust. And 1000 years past and a girl gives birth to a baby, Finn. Seeing that the baby was compleately non- mutated. He wouldnt have survived down in the sewers. Or even worse those Glub glub things attacked the underground city, and attempting to flee Finn's mother loses him in the process trying to get him to the surface. Which would explain how jake's parents find him and eventually raise him. I also belive that susan strong is his sister or at least cousin and nothing will convice me otherwise. She seems to waaaay too young to be his mother. —Preceding unsigned comment added by Miss Cinnabun (talkcontribs)

Were Fionna and cake real?Edit

I think that the ice Kings fan fiction about fionna and cake could have been real ,before the Great Mushroom War when Ice King was still Simon Pikatrov, I could be wrong, but this is just my oppinion .

in the episode " Beautopia" a Lub Glub was seen chewing on a Fionna -like skull , so this could be proff that Fionna and Cake were real and had lived one time or another , perhaps Fionna and Cake had been Simon Pikatrov's friends , or could have rescued him or Betty one time , maybe he had fond memories of Fionna and Cake ,that he could never forget, and when he became the Ice King , he still had these memories in his mind , but he forgot some of them and could only vagely remember Fionna and Cake, but not the nice things they did. Perhaps Fionna and Cake reminded him of Finn and Jake , so he just swapped the genders of the characters and put Fionna and Cake in as Finn and Jake in his fan fiction.

im not sure if this is true , but when you think about it for a while , it kind of makes sence—Preceding unsigned comment added by Miss Rainicorn (talkcontribs)

Not likely. I envision Fiona as Finn's long lost twin sister (as seen here) whose mom died during the Mushroom War (or as I call it, World War III). Also, Prince Gumball & Princess Bubblegum are more likely to be cousins. Finn's fear of the ocean stems from the fact he & Fiona were thrown from a ship by a nuclear blast & they drifted away from each other. Finn washed up in Ooo, went into a forest & had that infamous Boom-Boom moment. Fiona washed ashore in Aaa & also had a Boom-Boom moment. BNSF1995, Alive since 1995 01:15, June 8, 2011 (UTC)

jamesfollows' theory: Recently, I've rewatched three episodes. I've worked on one of those crazy theories that hardcore fans love and/or hate. Episodes to watch: Susan Strong (episode), Fionna and Cake, Beautopia. Premise: Susan Strong (character) is (a) Fionna, or (b) Fiona's Daughter.

To get to this I thought that at the end of Beautopia, Susan is a human (debatable among people). Susan may/may not have fins (ha... Finn) but what she does have is long blonde hair... Interesting. Also, in the current show, Jake and Lady Rainicorn are are having kids, this could mean that Cake and Lord Monochromicorn would also. Okay so, believable evidence sorted, now the ties. What does Susan Strong wear? Oh... That's right... A blue shirt and a Black Cat headpiece. Blonde hair flowing underneath.

Now, the reason I'm more leaning towards Susan being Fionna's daughter is that during Beautopia, we see a hat similar to Finn's (possibly Fionna's). Plus, we would need someone musclular enough to make Susan... Perhaps an inverse of Muscle Princess?

A theory I heard was the Fire Kingdom was annoyed with the Hyoomans and stopped Beautopia's fire. Possibly Flame Prince being jealous that Fionna picked someone other than him. Prince Gumball/Uncle Gumball tried to save them by chopping down all of those trees in one night (but failed), and as a result Susan was raised by the Hyoomen Tribe until we meet her in the episode.

Ooo: Result of Continental Drift?Edit

Could Ooo be the result of a continental drift?

What makes you think the world was involved in the Mushroom War? It could have just been a spiff between two countries that destroyed the world, just two countries doesn't make it a world war... felinoel ~ (Talk) 03:07, June 8, 2011 (UTC)
The episode where Finn's fingernails are shown to have grown to insane lengths-he must have been put to sleep for a long while, perhaps the Ice King froze him? ShinxfelinoelScraft 13:41, April 16, 2012 (UTC)
According to my theory mixed with your theory, Finn was completely frozen except by his hands for almost 5.5 years.Afliador8 20:26, April 16, 2012 (UTC)
I don't know if this is already confirmed, but... What if Heat Signature and the other "movies" Finn and Jake watch are military tapes of past wars? They look pretty much about ..soldiers. FrFines 18:11, May 27, 2012 (UTC)

Adventure Time Theories Edit

ver since the first airing of the episode "Fionna and Cake," the genderbent counterparts of the Adventure Time characters have become extremely popular with fans everywhere. Some believe that the genderbent characters should have their own series, but that rouses a question with me. Is that really necessary? Do we really need to give Fionna and Cake their own series? Now don't get me wrong; I would love to see more genderbent episodes as do many of you. But it seems to me that the big concern is that Fionna and Cake cannot exist in the same world as Finn and Jake because they live in a parallel universe where all of the genders are different. I, however, have a different theory.

Do Fionna and Cake really live in a different world? Were they real characters that existed at one point in the Adventure Time legacy, or were they just the strange fantasies of the Ice King that he came up with in fanfiction? In this article, I would like to touch upon some points that suggest the genderbent characters may have had a place in Adventure Time after all. With the evidence portrayed later in this article, I believe that the genderbent characters were the past generation, that they existed before the regular characters in the series.

Before I begin, however, I would like to make clear that this is all opinion and that I am not suggesting that this is or should be real. I just happened to notice a few things that drove me into contemplation about where Fionna and Cake are, and I am willing to accept input from others that counter what I say and suggest that I may be thinking about it too hard. With that said, I will display my findings.

Fionna + Cake = Susan Strong?

Something that I happened to notice upon watching "Fionna and Cake" was that Fionna had a striking resemblance to Susan Strong, who made her debut appearance in the previous season. I also remembered that Susan wore a hat that appeared to be made out of a cat. My theory is that Susan Strong is Fionna and her hat is Cake. How did this happen? Here is what I think:

Fionna was fighting off an evil force or creature of some kind with Cake at her side. It was too strong, however, and the duo was unable to defeat it. The evil occult lunged for Fionna with the intent of killing her, but Cake leapt in front of her and took the fatal blow. She died instantly. Before the evil creature could kill Fionna as well, several onlookers joined the fight and took down the monster. It did, however, manage to give Fionna one last blow to the head. She lost all memory of her past life due to her injuries, but she was found by a group of Hyoomens who were willing to take her in as one of their own. She was taken along with Cake's body into their city of Beautopia. Fionna made Cake into a hat to match the animal hats of the Hyoomens and made it her primary goal in life to protect the Hyoomen tribe. It proved to be a tiring job, but she worked hard to keep here people safe from any outside force. She built up a great deal of muscle, earning her the name Susan Strong. At the end of the episode "Beautopia," it is greatly suggested that she is a pure human like Finn, which adds to my belief.

PB and PG are related?

At the very beginning of the episode "Susan Strong," Princess Bubblegum mentions that she had an uncle named Gumball. It's very implausible that the niece of the prince is next in line for the crown, and I don't know that much about hierarchy so this section may or may not be valid. My theory, however, is that Prince Gumball never married or had children of his own, and Bubblegum's parents may have passed away somehow. This would mean that she was one of Gumball's only family members around and made her next in line for the crown by great default. I know this is kind of a stretch, but again I don't know that much about priorities when it comes to who gets the crown. Feel free to correct me.

Vampire King and Queen

Marceline holds the obscure title of "Vampire Queen." I am unfamiliar with any benefits that she gets from this title, but it is revealed that there was once a vampire king before she killed him. The evidence surrounding this unnamed Vampire King is still in the shadows, but my belief is that the title was given to Marshall Lee. Possibly what happened was that Marceline was betrothed to Marshall by her well-meaning father, but she was in love with Ash at the time. Her options for escaping marriage to Marshall were to either kill him or resign her position as Vampire Queen. Not wanting to sacrifice her title, she killed Marshall and ran away to live with Ash.

The Rulers of Ice

It is revealed in the two-part series of "Holly Jolly Secrets" that the Ice King is a survivor of the Mushroom War. While he was still human, he found a crown that slowly transformed him and cursed him with irrational thoughts. It is possible that a second crown was found by the Ice Queen, and they both slowly morphed into the evil rulers as we know them. The Ice Queen was the first to live in the Ice Kingdom and search for a prince before the Ice King happened upon the land and tried to overtake her. The Ice Queen fought as hard as she could, but at this point many of the princes have disappeared in one way or another and there were now more princesses in Ooo. Finally, the Ice Queen left the Ice Kingdom in pursuit of more princes and allowed the Ice King to take over.


Well, I think I covered the basics. I would like to end with a reminder that this is all opinion and I am not trying to tell the creators of the show how it should or shouldn't have gone. I'm just giving my own views and input and am willing to hear the thoughts of others if there's something I missed. Until next time,

Good theory although Cake isn't black she is white with cream spots. So not hat. Also it is clearly stated that it is a fan fiction although due to the similar names (Uncle Gumball and Prince Gumball) it is possible that they are based on real characters as Ice king is a very old and may have come across many character's. Although his being in this part of Ooo may be due to Marceline who he not knowingly follows. Azikiwe17 (talk) 21:26, December 4, 2012 (UTC)

First of all, that is Cake's fur color, not skin color. Secondly, you mean Uncle Gumbald, not Uncle Gumball.

Adventure Time Theories Edit

So obviously PB is like 1000 years old, but she has pictures and mentions of family in numerous episodes. Also, the Ice King is old and bananas, and the only one who knows his stories is Marceline (who rolls with the gender-swap fan fictions)----why, maybe because she knew the stories too?

My favorite theories are: Marshall Lee could be Hundson Abadeer, Fionna could be Susan Strong, and Gumball could be some relative or an odd experiment of PB. Cake and Mocro could have also had a black kitten sort of thing for a kid (like in Jake the Dad), which ironically makes up for Susan's hat, but I'm just throwing around ideas.

The Susan and Abadeer relationship would be an interest plot twist...unlikely, but Marceline acts like a sister to Finn already?  Just some fun ideas...

Bonni can create her own family, she made someone specifically to be her boyfriend so she can just as easily make a great uncle.

Ooo is France? Edit

Now, I know you're thinking that's entirely rubbish, but hear me out, just for a bit. Bear in mind that the only full season of Adventure Time I've watched is Season One, and I haven't seen the official maps. This is pure speculation.

First, there's the sunken city in "Ocean of Fear". It's out in the ocean, not directly off the coast of Ooo. It could easily be more than the length of the English Channel away, and thus could be London. The cars there are all driving on the left side of the road, so it clearly isn't in America, which is where the crater is. On top of that, in the episode, "Evicted", we see that the Ice Kingdom goes directly down to the water from the mountains. These could be the French Alps, and the sea that Finn and Jake escape to could be the Mediterranean. Though this is all compelling evidence, it could still be somewhere such as Japan.

This is why we must take into account the names of the characters, and the different languages spoken in the series. First up is Marceline and Hunson Abadeer. The name Abadeer in itself sounds as though it could have French origins, as does the name Marceline. Although nobody has a French accent, this could be due to the fact that clearly no humans had been around for centuries, save for Finn, to keep the accent alive. As for Marceline herself, she grew up with Simon, who did have an American accent.

Simon Petrikov is clearly Scandinavian or something of the sort, but we've seen that once he fell to the crown's influence, he began travelling, taking Marceline as a companion. Perhaps he picked up an American accent from being in America before it blew up, and that's where Marceline gets it from.

Of course, the clincher is Finn. Finn Mertens.

C'mon, that last name is ridiculously French-sounding; It was clearly just mispronounced in "Finn the Human" and "Jake the Dog".

So, yeah, that's my theory. The different shape could be continential shifts? I dunno.

My problem with this is that due to the nuclear war that ravaged the planet and threw a chunk of it away Ooo could very well be the bottom of the Pacific Ocean if anywhere else.

Hey everyone im a new user and just watched the latest episode of Adventure Time, dealing with Prismo dieing so sad and the Lich making a comeback, oh yeah hey Finns dad is alive and he saw him. Well im not here to talk about this but to take another look on this whole series back story, because they leave alot of untied knots to me and its like a cliff hanger awesome for ratings terrible for us if you know what I mean. But I've been looking at a ton of theories for the back story , Fiona; Ice Kings fan fiction is real just he forgot and its actually in Simons mind but the Ice King has taken over so much it's gone to his mind and he might be misinterpreting it. , Another Finn and Princess Bubblebum are actually siblings but remember Finn was in a comma and forgot but Princess Bubblegum never did but never told, And lastly Susan strong is Finns Mother, or their siblings and Fionas both their mom and Prince BubbleGum is the Dad, and also Prince Bubblegum is Princess Bubblegum's uncle.

Well I'm here to tell that this is not all completely true cause it's impossible for us to actually come up with who is actually Finns mom because we just recently found out who his dad, A good for nothing convict, who Prismo died for, left his child and went to another dimension with other convicts, and saw his own sons arm ripped off with not a morsel of sorrow(WHAT WERE YOU THINKING BILLY, FINN WAS FINE WITH JOSHUA, WE ALL WERE) but his mom is older than Susan Strong bacause we just saw his dad and he was pretty old but in the episode he saw he was some type of substance that preserves life so his dad who names escapes me is older that he looks, but we also have to take in that this is all after the Mushroom War(World War 1 and 2 I presume) I think it's awesome yet terrible how someone has such a great mind to think up such a cataclysimic world and yet make it a children's cartoon(I GIVE YOU PROPS CREATORS). But seriously this has beeen running through my head since the show first went back went in time and showed us Simon. But I would love to read your tangents or memoirs about this because its racking my brain, but again maybe that's good, but this is all I could think of to make the most sense and followimg what I have seen and what I will also happen in the future.

HOPEFULLY IT GOES ON WITH THIS STORY LINE, ONLY THE CREATORS KNOW, but seriouslsy shoot some ideas out im always ready to read.

I don't think that Finn and PB are siblings. Even if, like you say, Finn was in a coma and forgot but PB didn't, PB in "Too Young" was actually interested in Finn romantically, which would make their relationship incestuos and gross!!!!!!!!!!!!!!!!!!TobdanHowelleski (talk) 20:01, June 9, 2014 (UTC)
