Best Gravity Falls Monsters

He finds pain hilarious. He's a yellow one eyed triangle with a bow tie, a top hat and a cane. He infiltrates mindscapes, dreams and alters alternate universes. He knows a whole lot. He's always watching. He calls Dipper, Pine Tree, which is adorable. He's cunny, feist, smart and ridiculously hilarious. He finds pain hilarious. He knows how to make really good deals. He knows the weakness of minds. How is he not the coolest monster ever?
Bill cipher is my favorite character of all animated cartoons. He is just creepy, funny, and anything any sort of character in any show should have, except for being able to really relate to him, but there are no antagonists in any other show that are as stunning as he is.
Witty, clever, charismatic, but is the most demonic being on the show. His lines are hilarious one second and then the next second he's on the hunt to possess or even murder someone. I also like how he "charms" his victims before tricking them. He is my favorite villain of all time.
The scariest thing about Bill is that he doesn't feel. He was made evil, and that just proves that people are born evil. Yes, villians are made most of the time, but instead of getting a villain with a stupid sob story we get a villain made out of pure evil. He has done things that are terrifying. I'm scared of him but I also love him
An excellent multi-layered villain. I loved the homage to No-Face from Miyazaki's Spirited Away. He was creepy and awesome. He instilled genuine fear.
I am dead serious when I say this, he is creepy! I mean, what is more messed up than eating a child alive on screen!?! Definitely worth second place!
I feel bad for the Summerween Trickster and he reminds me of Noface from Spirited Away.
And how great would it be if we celebrated Summerween!
A really creepy monster plus I think he is the cartoon Slenderman.Think of it, they both grow tentacles, they stalk children, and they are really creepy.I like the fact he is made up of "loser candy"(he even cries candy corns) and he has development for his "stalking" nature.
Why do they have a category for gnomes and shmebulock!?! he's definitely the best gnome but he's really no different than any of the others. (Other than his limited vocabulary)
They barf rainbows! Does anything else need to be said?
Let's barf rainbows guys!
I can't talk today
Only appeared once, but still made it on the list. the damn bear needs more recognition with his disco girl songs!
Bear's are awesome. Bear's with eight heads are even more awesome!
I Love the "Real" Gobblewonker not the Robot but the real one I mean we barely see him but he looks better than the bot though and I would tell you to shut up and take my money if they made a movie all about the Gobblewonker. I also hope he come's back if the show does the same because he...is...awesome!
He is always stealing Wendy's moisturizer. How can you do that?
Lil Gideon? Oh god, that little gremlin man is terrifying.
I know he's not a monster but he's so funny and small!
I'm laughing so hard right now..
Overly attached girlfriend meets Gravity Falls. Not my favorite but needs to be on the list at least.
She should be second. She is FNAF for kids. None of these people can be FNAF, except Bill. She was willing to destroy anyone, and almost did. I will also admit I like her hair.
I agree. What is more creepier than a haunted dating simulator!
At least out her over characters that aren't in the series!
"Should I be One or the other? How about Both! " Oh my god, that was the CREEPIEST moment on this show period. Plus he can be any monster, can talk, and is probably the reason the Author wrote 'Trust No One! ' in Journal #3.
This may be a kid version of The Thing but make no mistake, the concept will still keep you up at night. Next to Cipher there is no doubt in my mind Shifter comes second.
Oh my god the shape shifter is utterly terrifying. Anyone remember the part when he reveals he's the shapeshifter, or the morph he did of the Mabel+dipper thing?
Why isn't this in the top 10? By far the scariest monster, and by the way Gideon is not a monster.
The only monster I can relate to.
Oh, I love those guys!
Definitely the nicest monsters even though they sort of kidnapped the teenagers
This monster was actually good.
Anyone remember Stan punching him? I do.
The dinosaur is not today.Who thinks that the Pterodactyl is extinct?
"What would you do if you were trapped in a closet. Break out."
"No, It's just me, good ol' number 7." (7 falls off.) Did you see 2 and 3 in the credits?
Paper Jam Dipper is the best!
He's one of the gnomes, get him off the list.
The only true monster.
Well, he is satanic, gravity falls is too, so that would be a great combo!
Slender man isn't in gravity falls, and he will never be.
Slender isn't part of gravity falls monster. "Secret" 'Slenderman is an Easter egg...'
I love the hide behind. But I didn't see any in the show.

Didn't Alex Hirsch say his real name was Jesus?
Not a monster, but he's large and funny, and like a fat human bill cipher in a way
Come out! Come out! Come out wherever you are!
Yeah it is really creepy. At the end when he suddenly appeared from "behind" That dead tree gave me chills.
Have you seen the episode on him? Only monster to give me the chills
"Can I have my hands back now? I have a certain gesture I's like to share with you."
