Best Gravity Falls Theories

Here is a list of the greatest and most likely true theories regarding that of the hit Disney Channel and Disney show 'Gravity Falls'.

The Top Ten

1 Stanley Pines

Stan's twin brother Stanley is probably my favorite theory. It just makes a lot of sense. For proof check out the video 'Decoded #1: Stan's Secret Twin' on YouTube.

And he actually exists! Not What He Seems was THE BEST episode in Gravity Falls!

My all time favorite theory.

It's real he us in the show now

2 The Nuclear Apocalypse

Okay.. This one is just really cool and freaky at the same time. This theory states that sometime in the future, a nuclear mishap will lead to the downfall of Gravity Falls. I personally believe very strongly in it.

This one makes so much sense! I like it just a bit more than the Stanley theory

Almost correct but is

Confirmed in Season 2.

3 Stanley Wrote the Journals

Stanford wrote the journals, Grunkle Stan took his twins name

I think that Bill cypher is the bottom of everything- he wrote the journals conjured Stanley and Stan and then made dipper and mabel into this total mess- in which my theory is that Dipper's and Mabel's parents signed them up on a riddle camp and this is the riddle...

Not What He Seems confirmed this, although it don't think his name is Stanley, I think that Stan faked his death in order to write the journals, and the one being Stan at the shack is Stanley.

Again with Stanley... For more information on this theory, search this video on YouTube: 'Decoded #1: Stan's Secret Twin'

4 Soos Knows More Than We Thought

We already know that Soos knows about the journals because Dipper told him in one of the shorts between Season 1 and Season 2 and he entered Stan's mind to defeat Bill in Dreamscaperers, but what if he knows about the secret societies and more?

The future is coming to all us dude

Soos knows LESS than what he seems

Don't judge a book by it's cover.

5 Mabel's Future Disappearance

This is a theory you probably didn't really hear before. It's really interesting because this theory has various movie references that support it. Search for it on YouTube, Google, bing etc. for the explanation.

Alex Hirsch confirmed in Season 2 on character will not make it alive.

This will most likely happen very soon

Mabel is the sister we always wanted, twill be shame is if she was to disappear... but she told me she was just going to have a sleepover at her friend's house...

6 Mabel's Paranormal Twin

This... doesn't make any sense. The bottle is an animation error, the picture was a goof, and... that's all the evidence people have. I can't make a long comment because there isn't anything to comment on.

There's a theory that In the episode Double Dipper Mabel made a copy of herself on the printer and named it Lebam Mabel backwards.

It was dipper who made copies of himself... That's why it's called Double DIPPER! - FuffleyandPeetah

Some believe Mabel has another twin, but in another dimension. Her/His name is Lebam. (Mabel Backwards)

An idiotic thermals by the idiotic Vailskibum

7 Robbie Is a Zombie

Makes sense, but his parents own a funeral home and a graveyard if he was a zombie they would know.

When dipper reads the description for zombies in tourist trapped, it fits robbie; 'pale skin', 'bad attitude', and he kind just acts like one if you re-watch the series.

There is a lot of information backing this up, such as Robbie's sweatshirt, his band, the minivan in The Inconveniencing, etc.

OOOR... Robbie is actually a teenager... He has a lot more personality than a conman zombie, he can love, hate and process other human like emotions and characteristics.

8 Bill Cipher is Still Alive

Best theory for da best character! Bill probably helped stan recover his memory and probably is not as we think! ( My opinion theory combo, anyway...)

This is actually very likely, knowing Bill's power. I think that Bill Cipher survived and created a stone replica of himself to trick everyone so that they wouldn't be expecting his next weirdness invasion.

I think that since Stanley got his memory back, there's still a small part of Bill Cipher in there and he's waiting for when he's strong enough to leave.

They should make season 3 when bill comes for revenge

9 Stan's Tattoo

Well it is possible I mean their is little Easter eggs and little codes. Such as their code.

You mean when Ford pushed him while fighting.

Stan's tattoo is actually a burn mark when Stanley pushed him when they were fighting. I also think that these comments are out of date.

I believe Stanford's Tattoo is some kind of urgent code that has not yet been deciphered.

10 Carla is Gideon's Mom

So obviously Bud (when he picked up Carla) became fatter, changed from blonde to brown hair AND went from a hippy to a Texan? Theory busted...

When you think about it, it's actually possible...

By far my favorite. I may or may not have voted for another one before I saw this one though.

She does have a memory bottle in the society of the blind eye

The Contenders

11 There Is More Than One Secret Society

I don't know if this one has been confirmed or not, but there may very well be two societies in Gravity Falls: The Royal Order of the Holy Mackerel and The BlindEye Society.

It's so real because stan has a picture of the royal order of the holy mackrele

12 Pacifica Works With Bill

If Pacifica was working with Bill, why would she be trying to stop him in the final episode?

That makes sense, actually. The llama si facing backwards, which probably means Mabel's former enemy, Pacifica.

That makes no sense

Just look at Bills wheel. Look at the llama. Then look at the llama on one of Mabels sweaters. They are both facing opposite ways. Who knows? This might mean something

13 Dipper is a transgender

Definitely my favorite theory, and there is a lot of evidence to support it. Dipper and Mabel are nearly identical, so I think they were born as identical twins, both girls. This could also explain why dipper only goes by his nickname, and gets upset when he feels like he's not manly enough.

I totally agree with this. Quick Question though: now that we know that Dipper's real name is Mason, what was/is his female name?

Well, if you were a guy and someone told you you weren´t manly, wouldn´t you get defensive? Also, a certain flashback from Escape From Reality says otherwise


14 Dipper Is Possessed by Bill Still

In the episode with the shape shifting monster it said that dippers final form would be him sort of frozen with his hands in the air much like how he looked when he was turned to wood in northwest mansion, so maybe that was his final form and Bill took over his body then.

Also Alex Hirsch said that there was some1 going to die in ss2. Maybe that's Dipper. Maybe he had already taken his last form in the Northwest mansion like what the Shapeshifter said and Bill had already taken his body since then when he was turned into wood.

Dipper would never brush off an upcoming apocalypse, but I know a certain triangle who would!

Dipper also walks with his hands on his hips. Weird because Dipper only walked like that when Bill took over his body.

15 Bill's Only Weakness

I think that his eye is the weakness. when Dipper tried to punch him in the eye then Bill pushed him away because he didn't want him to know his weakness.

His weakness is Gold... This one is hard to explain. Look this one up also to find answers,

This is a awesome theory!

He has only one eye... it could be lack of depth perception.

16 Bill Cipher Statue

It means something big very big

How is this a theory?


Its in Oregon for real and it has treasure and its by some rusty gates in a forest.😉

17 There's a Journal Number 4

Considering the 3 were burned, and dipper still has no clue how to defeat bill, another journal would make sense.

Highly unlikely.

Sounds awesome

No one ever said that there are only 3 journals.

18 Gravity Falls Was Supposed to Happen Differently

If you think about it...

So, things would have never happened in Gravity Falls if it weren't for time travel. Soos would have never worked at the mystery shack. Wendy wouldn't be friends with Dipper. Toby Determined would have been successful. Soos would never love his birthday. Robbie might have turned out different. Mabel wouldn't know how to open the vending machine. Here's why.

When Dipper and Mabel go back in time to the past Gravity Falls, they leave behind things. Traces of them.

Toby doesn't become successful because the twins told him that his dreams went nowhere. Perhaps if that hadn't happened, Toby would have become a Broadway performer.

Soos wouldn't have worked at the Mystery Shack. He would have never returned the screwdriver. He also would never have met the genius (Mabel) who tag ht him how to open the vending machine. It gets confusing here. I'll go back to this later.

Wendy wouldn't have made good friends with Dipper. When does ...more

Soos wouldn’t work at the mystery shack, Mabel wouldn’t be able to open the vending machine and Wendy might not have been friends with Dipper

19 Mabel is the Key

In every episode that Mabel fell in love, every character wanted her as their "queen" or their "leader". Maybe if Mabel is the key, every magical creature knows and that's why they want her as their queen.

Her sweater in not what he seems is a key. Hm

Think. She decoded almost evereything in Irrational Treasure, she's an official congresswoman, she solved Dipper's math problem in the Time Travelers Pig, and there was even an episode called Boss Mabel. She is the center of evereything in the series (and not because she wants to be)


20 Soos Will Die In Season 2

I agree maybe the handyman knew too much, also "you guys are smart, especially the fat one".

It's a Disney show, what is wrong with you guys?

There is no season two as you see it shows the endowing on weirdmagedon three

Soos said that he would do anything for the pines family...and this would mean a sacrifice

21 Pacifica's Memories Were Wiped

If you remember the episode with the memory wiping machine in the background you can see a canister that say's pacifica's memory's! This explains why she has blonde hair while
Her "parents" don't there is another theory that goes the same but instead is buddy's wife

Remember on Northwest mansion there is a banner on the wall with Bill on it and people sre praying to him. well I think that they knew Bill and that there memories were whipped from him. because onweird meggedon the Northwest family clearly did not know him.

I bet pacifica use to be nice it then the socity of the blind eye erased her memories and she became mean. 😏

You are so right me and my friends are doing a YouTube channel called theorie hunters - - -

22 The Portal Leads to Hell

Alex said it leads to the kind of places Bill and his pals like to hang out. (Does Bill like to hang out in hell)

Considering how the Author (Spoiler) destroys the portal, and refers to it as dangers. And the countless references of chanting, summoning circles, posessions, etc. I'm sure Alex Hirsch is willing to go as far as hell and demons spilling into our realm.

Yep this theory is right. Bills world pours into ours in the latest episode. And his friends,

Bill is called a dream "demon."

23 Stanford Will Die at Age 92.

Bill did once say to Ford "Don't have a heart attack, you aren't 92 yet," when they first met. As Bill knows pretty much everything, Ford will probably die at age 92 from a heart attack.

Bill said don’t have a heart attack, you’re not 92 yet

I doubt it. Ford is strong🙇

24 Mabel Likes Likes Dipper

No this isn't anything! They're siblings gosh! They're just siblings at they're finest! Mabel doesn't like like dipper but she like likes him as. BROTHER!

Would understand why she so attached so acttached to dipper and made a big deal about him going to do his dreams with stanford

TF no

25 Stan's Secret Brother


26 The Blind Eye Helps

The blind eye is against bill cipher.Have you ever noticed on the page the blind eye there's a eye with a line crossing it.

27 Bill Cipher Wheel

The zodiac dipper, Mabel,Robbie, Stan,Ford,Old Man McGucket, Pacifica,and Wendy .

It's called the zodiac in weirdmaggedon part 3

28 Stanley Pines Was Forced to Leave His Child

Think about it. The Pine's twins have parents, and whichever one is from the Pine's side has a great enough relationship with his "uncle", that he regularly sends his kids to visit in the summer. The backstory also inferences this.
Grunkle Stan claims to have married and divorced once. In that time, he must've had a child. However, he probably divorced when the child was too young to remember, and therefore the kid did not recognize his father impersonating his uncle(either that, or his child and ex-wife knew he had a twin, just that they never met, and therefore had no idea it was fraternal.).
When he was down on his luck, and invited to visit his brother, he was probably recently divorced. Impersonating his brother was a fresh start, but he probably felt guilty about leaving his child. Therefore, he continued to visit his child by pretending to be his/her uncle. By doing this, he could avoid visitation and legal restrictions, and cultivate a fatherly relationship with his ...more

29 Gideon Works with the Government Agents

They both have the same USA flag tag on them and its strange that Gideon has all these powers and he's only a kid.

Stop watching bad Vailskibum videos
Plus he talks like he's foaming from the mouth

30 The Father Knows About the Journals

He might know because he knows about Stanley so he must know Stanford and the journals

...Who's father?

How does Gideon know about the journals.
Also,the father of Gideon hypnotize the accident?

31 Dipper and Mabel Will Drift Apart

Dipper and Mabel will fight in a upcoming episode they will probably have a similar thing that happened with the Stan twins happen to them.

Dipper and Mabel vs. The Future


32 Bill's Twin

There is a theory that Bill has a Twin brother, either a square, circle or upside down triangle!

It might be a girl called Jill Cipher.

It could be a girl named Jill Cipher!

33 Wendy will die
34 Wendy Recognizes Dipper And Probably Likes Him Back

Gravity Falls ended years ago but this thought just struck my mind. What if Wendy recognized Dipper and had a crush on him?

1.In "Scary-Oke" we have a glimpse of Wendy's bedroom in which a photo of Dipper (presumably) in her wall. Which looks like it has been drawn when she was younger.

2.In "Into The Bunker", Wendy said that she's super flattered and is too old for Dipper. But they still remained friends throughout the series. When Wendy breaks-up with someone, mostly it will make her mad. But in this case she is sincere to Dipper's confession. She also said that if Dipper stops being her friend she would throw herself into the "Bottomless Pit"

3. In "Society of The Blind Eye" she revealed that she is not laid back and is stressed by her family and is just keeping it a secret to everyone.

4.In "Blendin's Game" Dipper and Mabel time traveled 10 years into the past from their timeline and we see younger ...more

Why would she have a picture of him that it looks like she drew in kindergarten?

35 Mayor's Upcoming Death

There are several codes in the Gravity Falls book stating the mayor doesn't have much time to live. Another code being that Bud Gleeful wants to become mayor.
My theory is that Bud will eventually become the mayor of Gravity Falls, which is of course not good, at all.

I think that the mayor is the one that was supposed to die.

This one's true just watched a new episode

In Weirdmaggedon 3, Bill had eventually captured the kids. He said he was going to kill one of them for the heck of it. He started with Dipper. "Eenie, Meenie, Minie, YOUUU! " He stopped at Mabel. She would have died if the Older Twins didn't switch clothes and trick Bill. Think people.

36 Robbie's Secret Clone

This is a well thought theory because in Gideon Rises he is almost at 2 places at once

His reflection is reversed in “inconvenience” AND his younger self is different in “love god” and in the globnar episode

37 McGucket Knows More Than Dipper and Mabel Think

Uh proved already

38 Dipper Will Die In Season 2




39 Stan Will Die In Season 2

It have to be Stanley that dies, remember when Stanford meets Bill, Bill says, "Don't have a heart attack you're not 92 yet."

40 Pacifica Was Adopted

Well I mean Dipper even pointed out that her blonde hair is "probably fake." She most likely had it dyed.

It kind of makes sense. I mean, she doesn't look anything like her so called "parents" and she has a different hair color then them.

She doesn’t look like her parents.

41 Robbie Was Possessed

Robbie was a cute little kid until one point were he turns almost demonish. It was shown when Mabel delivers him pasta to his bedroom, he had photos of him in his hallway. Also, in the episode where Mabel and Dipper time travel back to find out why Soos hates birthdays, Robbie looks like a mini him, even though I'm the hallway pictures, he looked much different.
Maybe it was an animation error but he must have a big part in the plot to be on Bill's wheel.

You're right! He does look a lot different in those two episodes!


42 Stanley and Stanford are the Same Person

This doesn't even make any sense...

That is so wrong

Maybe Stanley wanted to get away from people so the answer...A CLONE!

Here's how...

Stanley wanted to get away from people so he could concentrate on his work. So he goes back in time to when he was a baby. He gets a cloning device and clones himself. That's why Stanford and Stanley have similar names. He puts the babys in a crib. When the supposedly "twins" grew up together. But the clone grew up differently then Stan. They went there different ways.

*Time skip* When Stanford got sucked into the portal Stanley went to take care of the shack and it was his duty to get him back. Stanley felt it was his duty to get his "brother" back because that's him. They're the same people. And He wants to save himself.

____________*MIND BLOWN*__________

43 Bill Has Trapped Mabel and Dipper in a World Where He Keeps Winning in a Loop

Cause bill can make world like when he had trapped Mabel

44 Bill is Gompers

Whenever Bill posses someone their eyes get dilated. Gompers eyes are dilated. Also when Dipper first finds the journal Gompers tries to bite it. Bill wanted the journals gone.

It wont be after they sprinkled the magical spell he would not be able to get near the shack

Stupidity at its finest.

45 Gideon is His Parents' Dad

There is a theory that Gideon is his mom and dad's dad. The evidence:Gideon's parents are afraid of him. Reason:Gideon got trapped in the portal and it made him younger after having kids. That's why he wants the journals to go into the portal, find the thing that made him young, and get old again.

No, wait- THIS is stupidity at its finest.

AND the fact he has white hair

46 Mabel is Transgender

OR, she´s just a really girly girly girl

Mabel is always being girly, obsessed with Several Timez, boy crazed, and has a sticker and glitter collection. She tries so hard to be girly. She might be trying so hard that everyone thinks she was born a girl. Everyone thinks it’s Dipper who’s trans, but he’s just acting like a normal teenage boy.

47 Bill is Dipper
48 Everyone But Mabel Will Perish

I agree with the previous comment, which states that only one of the Pines will survives. So it's either Stanley, Stanford, Mabel, or Dipper.

As I see, Stanley Pines was trapped and made into gold by Bill Cipher, so it isn't likely for him to survive and I don't think Bill Cipher will resurrect him back.

As for Stanford Pines, I think he is gonna die because
(1). In the "Take Back The Falls" flag, there's no symbol of Stan,
(2). All of his models have been "murdered", mostly by fire. Maybe he will die with the same cause,
(3). He mentioned about his death somewhere in Season 2, and
(4). He's just too old for this.

Do you know that Alex Hirsch said that there will be no Season 3? Well, it probably is because Dipper dies. Dipper will also protect her sister (Mabel) from any kinds of danger, and I think that one of the scenes of the last episode will be Dipper saving Mabel from her death, sacrificing his own life. That leaves us with Mabel surviving and ...more

In weirdmaggedon part 1, the end code states "GAME IS OVER, AND I WON. NOW IT'S TIME TO START THE FUN. I ALWAYS LOVE CORRUPTING LIVES. NOW LET'S SEE WHICH PINES SURVIVES" which is saying only one will survive. and so far, Mabel is the only one without a death foreshadow.

So you know the events of Weirdmaggedon, yet you can't even get Stan and Ford's names right?
