Worst Adventure Time Characters

Adventure Time is awesome, but some characters are not.

The Top Ten

1 Princess Bubblegum Princess Bonnibel Bubblegum of the Candy Kingdom is a fictional character in the Adventure Time animated series on the Cartoon Network.

She started off as a likable, fun living, carefree, smart and responsible character. But slowly for surely, she becomes power hungry, dishonest, selfish, genocidal, sadistic, and mean spirited as all hell. She almost never gets punished for her cold hearted actions.

I thought she was a boy before I heard her name. - NerdyPweeps

Princess Bubblegum used to be likable, fun living, carefree, smart and responsible character and beautiful but now power hungry, dishonest, selfish, genocidal, sadistic, and mean spirited and TOXIC person and annoying retarded and god wannabe and she always ignores finn and jake and what is She the sakura haruno of adventure time more like She the kairi (kingdom hearts) of adventure time good thing I didn't watch the finale

Bubblegum was nice in the first few years then she got really annoying because she is bratty and mostly power drunk and she tried to kill the entire flame kingdom because she thought they were a threat which they weren't and she send Finn really confusing messages to Finn she wants him she only wants to be friends and when flame princess gets too close to Finn she tries to kill flame princess later by trying to wipe out the entire kingdom and she locked up flame princess for most of her childhood what. The. FLUFF is WRONG with princess bubblegum I honestly think that Finn should leave her on her own and not save the candy kingdom because the enemies that attack the candy kingdom were caused by who? BUBBLEGUM that's WHO! She was so nice now she's just annoying and bratty and how dare she say magic isn't really when she gave Finn Billy's magical gauntlet I kinda wish flame princess would melt her or I wish that peppermint butler would just shut her up I wish that I could go into the ...more

2 Tree Trunks

I liked her in the first season, but then she started spouting things that seem immoral and against what the writers set up for her character in season 1. Like she is 100% okay with forcing people to watch her PDA, but moving in with someone before marriage is "wrong". And then at her wedding she insults Princess Bubblegum by calling the dude she wants to marry her "the one true King of Ooo". Seriously uncool.

Most obnoxious, stupid character ever. She is whiny, never shows any common sense, and takes five hours to say or do anything. I HATE Tree Trunks.

She cares about no one but herself, she's an outright idiot, and honestly, her pies are the only good thing about her... And that's it. I honestly doubt even Finn and Jake would come around if she didn't make pies

Please kill this character. I BEG OF YOU! I just space out when she talks, acts, does anything, its like a hole in my memory, except for the residue of loathing and boredom.

3 Lemon Grab

I was just waiting for adventure time to kill this character off. He was such a horrible leader, yet every time he screwed up, he was just given another chance by PB. If he were my creation, I would've killed him on the spot.

When the annoying orange died he came back as Lemongrab to haunt us. Curse you Cartoon Network.

He is one of the worst characters I have ever encountered. He makes me cringe, there is nothing redeemable about him and he constantly brings negativity to the story.

Annoying, selfish, socially inept, tyrannical, cringy, and temperamental. Need I say more?

4 Marceline Marceline the Vampire Queen is a fictional character in the American animated Cartoon Network television series Adventure Time, created by Pendleton Ward.

How the heck did Marceline even get on this list? She's awesome!

*How the heck did Marceline even get on this list? She's awesome! *
because she sucks

She is a vampire, hence her name Marceline the Vampire. I know there's lots of you, vampire fans, but she, in my opinion is the worst character of the series because she is a vampire like I said earlier. Vampires are said to be pure evil blood-sucking immortal creatures of the night. - DinoLover4242

Annoying, selfish, socially inept, tyrannical, cringy, and temperamental. Need I say more?

5 Flame Princess Flame Princess Is a Princess made out of fire and lives in her kingdom ruled by here evil father, The Flame King. Her first appearance in the show was “Incendium” (Season 3, Episode 26) She was Finn's girlfriend at one point in the series.

Almost killed Finn, done nothing besides of ruining everything... Why does that dumb one even exist on this world?

Flame Princess is stupid and dump and annoying. I can't describe how much I hate her. She messed up everything! Finn made the right decision to break up with her

Seriously... sometimes I think the only reason that she was introduced to AT was to make her break up with Finn and make Finn look poor and lonely because of her for the rest of the show!

Ah man. I really like Flame Princess. She's an adorable character with depth, not being able to touch anything, being locked in a prison all her life and now Finn's broken her heart. I kinda feel sorry for her and was glad when she took over her dad's kingdom (though I was kinda hoping for Finn and her to get back together too). - IpodSwagger

6 Me-Mow

Let’s All Remember the fact that this character was created by a lil Kid, So basically your hating a lil kids OC, the kid was like 6 or something, just imagine if he sees this

Useless character

I HATE ME-MOW - Ladysnuggles

7 Finn

He's cool, he just gets old after a while. No offense to any fans out there though, I totally respect your opinion. - NerdyPweeps

Finn is so annoying With his pointless relationships With princess bubblegum she too old for him also he not even a hero he hurts everyone & he annoying everyone as well he also Enter Marceline's house when I sew this I was so mad Seriously, I'm not kidding and if you love him I respect your opinion

Um... he WAS flipping awesome and enjoyable... until after his pointless relationships. now he's just a sad guy who wants someone to be with her.
His adventures are getting really less too...
Finn... you used to be my hero!... but now you're... never mind...

In the first two seasons he was funny, but later of that he was like a jerking depressed teen, only because back to crush of princess bubblegum and the flame princess leave him, he is stupid

8 Marshall Lee Marshall Lee is the gender-swapped version of Marceline, created by the original series designer, Natasha Allegri, who is featured in "Fionna and Cake".

I am surprised. He almost has as much fans as One Direction.

I love him, he's awesome!

Boring character

How dare you talk like this to my mar-mar I hate you

9 Ricardio

This guy is DISGUSTING. Look, I wouldn't judge a character because of how they were born as or how they look (I can't blame him for being made an organ), but the fact that he likes to be romantic to Princess Bubblegum in a way where he poisons Finn and Jake is just sick. Only twisted people like serial killers do such things. - MillieTrina_Prower

Worst antagonist in Adventure Time. - 05yusuf09

Ricardio is really creepy.

Hate him so much.

10 Ice King The Ice King is a character in the American animated television series Adventure Time. A supposedly evil wizard capable of creating and manipulating ice and snow, he is the self-proclaimed king of the Ice Kingdom, a land of ice he claimed as his own and lives in in company of many penguins.

People just hate him "because he's the main antagonist" and so on so forth. The Ice King is really funny and he needs to have more episodes focused on him. Ice King is kind of stupid, but him as Simon... That's a sad story. I just hate how he's so abusive towards his penguins and all.

Ice King just acts greedy because he's gone insane because of the crown he wears. In the past, he was quite solid hearted and took care of Marceline when she was sick and lonely during the mushroom war - SheepBuggy

Ice king is actually one of the most likable characters in the show.

Oh come on guys this poor dude is just misunderstood that's all

The Contenders

11 Shermy

Boring character

Who is Shermy?

12 BMO

BMO is so annoying and acts like a baby. He always needs Finn and Jake and is really stupid like in that "SHH" episode. He is just a burden and really has no point in the show. Being cute or whatever doesn't make him a great character either.

"Is annoying and deserves to die"

You wish, liar.

BMO is one of my favourite characters! If you hate BMO just because you can't figure out if it's a girl or a boy then you have some issues.

So many pointless BMO filler episodes with their weird imaginary adventures.

13 Magic Man

I think most of the characters on this show are annoying and stupid with the exception of a few, the show itself is stupid and annoying

His past and personality is very funny and interesting. I think, although he is a massive jerk, that he should be 24 on the best list - GuyInANateGrinder

He is one of the most interesting characters in the series!

Useless jerk that doesn't do anything. I HATE HIM!

14 King of Ooo

The King of Ooo was not a bad character. We were SUPPOSED to hate him. The writers made him the most unlikable jerk ever so his downfall would be all the more satisfying.

King of Ooo is a villain, and a jerk. We were supposed to hate him. - SheepBuggy

He threatened to burn down tree trunk's orchard! He should be #1!

He not beautiful, he's earwax.

15 Cinnamon Bun

He is such a creeper. I hope he falls into a microwave and Finn eats him as revenge for taking his girl. That would be the best episode ever!

When he was dumb, he had the same kind of humor that Patrick brings to SpongeBob. Now that he's smart, a jerk, and is a pedophile I will hate him for all eternity. GO BACK TO THE CANDY KINGDOM WHERE YOU BELONG!

I used to love cinnamon bum, but ever since he started sating flame princess I absolutely hate him. FINN AND FLAME PRINCESS ARE SUPPOSED TO BE TOGETHER

He used to be funny when he was dumb. Now that he's smart, he's boring and also a creeper to teenage girls.

16 Peppermint Butler

That whole dark magic thing just freaks me out

He kind of scares me - NerdyPweeps

He's creepy! If Princess Bubblegum knows how to do all kinds of science and things that others can't, why doesn't she know that peppermint butler is evil yet? - SheepBuggy

Why is he here? He's not creepy! He's my favourite!

17 Susan Strong

Most of these characters are great in their own right, but Susan always seemed very bland to me.

People only hate her because she's new to ooo, and doesn't know much about it so she acts dumb - SheepBuggy

18 Hotdog Princess

She's not in many episodes so I don't know too much about her - SheepBuggy

19 Flame King

Flame King should get arrested for LOCKING HER DAUGHTER IN A FIREPROOF LANTERN! That is bad parenting! - SheepBuggy

He is SO cruel
He just kept her daughter in a lantern for her whole childhood and harasses her that shes evil anytime

If the Flame King was real, I would rip his body apart and I wouldn't feel sorry for him

Flame princess is a monster she needs to be in a lantern

20 Wildberry Princess

SPOILER ALERT: She tries to kill Finn and Jake in the end of Furniture and Meat. In their own gold two greatest heroes in Ooo. I prefer BMO to shoot the arrow at her stupid face

That episode sucked in the first place. Such a waste of 11 minutes.

21 Abracadaniel

Princess Bubblegum caused him to go to jail by saying magic is science but MAGIC is MAGIC!

What? Why abracadaniel? - SheepBuggy

He's a big fat ugly wimp who sucks at magic


22 Deer Deer are the ruminant mammals forming the family Cervidae. The two main groups are the Cervinae, including the muntjac, the fallow deer and the chital, and the Capreolinae, including the elk, reindeer, the Western roe deer, and the Eurasian elk.

This deer is so weird because it's breath is so weird and makes pain

His name is stag

That's... a real... deer...


23 Choose Goose

Noo he's one of my favourite characters! - SheepBuggy

He is so crazy.
I will chop him and fry him the first chance I got.


24 Fiona

Fionna isn't all like Finn. She's supposed to have the exact same personality as Finn. But she just lets boys walk all over her- something Finn WILL NEVER do.

Fiona is supposed to be like Finn, but the opposite gender. Fiona is one of those people that just hates themselves and is all soft. Finn isn't like that at all. - SheepBuggy

Really, all the genderbent characters are my least favorite. That's just too much for one series. - Garythesnail

She is annoying.

25 Princess Cookie

Gosh he is so annoying. - NerdyPweeps

Princess Cookie needs to be eaten by me

He is annoying.
Plus "she" is a male - aarond09

26 Breakfast Princess

In Princess Day, she was so annoying to the point of me being on LSP's side.

Breakfast princess is only starred in one episode and in that episode she was so rude to LSP

She is my favorite adventure time chracter

I know, she called LSP a pamplemousse.

27 Martin The Human

The princess bubblegum probably will be a bad character, but seriously
A guy that forgot his son only to escape?
And don't import that his son is good or not? Seriously Martin is the worst character in all adventure time

Martin is more idiotic than Finn. - 05yusuf09

Only 30? He abandoned his own son - 445956

He is an absolute jerk who only cares about himself!

28 Jake Jr.

Jake's children are all lame as hell and they should all die in a fire. All the episodes about them suck.

She/he doesn't even have a face

Face freaks me out man

They changed the series,for bad

29 Bill Cipher Bill Cipher is a triangular dream demon formerly existent only in the mindscape who wished to gain access to the real world. He has been running amok in Gravity Falls, Oregon since being summoned by Stanford Pines over thirty years ago. He is known for his mysterious demeanor and sadistic humor. He ...read more.

Are you insane? Bill Cipher is NOT in this show! And also he is the best character in Gravity Falls? Some idiot put Cipher on this list thinking that he is an Adventure Time character. - Hellohi

Bill Cipher is in Gravity Falls...

Who put him here?

He is not even on the show,and he is great!

30 Kim Kil Whan

Wait he did that stuff? Wow, I really need to catch up on AT. I have hardly watched any episodes past season 4. - SammySpore

He's damn mean, as he sued his father, got him and Finn in prison, and is really greedy. - Comi03

He want to exclude jake and finn of his house, JAKE IS HE FATHER, WHAT THE HELL IS WRONG WITH HIM?

31 Gunter Gunter is the penguin that most commonly accompanies the Ice King in the animated TV series, Adventure Time and a major recurring antagonist of the series.

Gunter is super awesome. I don't know why he's on this list. It makes no sense

How could you hate a penguin?

Gunter is a bad character

I will kill the person who put Gunter on this postition

32 Prince Gumball

He looks like a jerk. He sounds like a dork. His dinky crown is the size of an ant- and since when does princess bubble gum like Finn? ( it's ment to be an exact replica of the real adventure time storyline you know).

I thought he was a boy when Adventure Time just came out...

33 Ash

One of my favorite scenes is when Ash was murdered by Marceline kicking his face, Finn jumping on his stomach, and Jake turning big and stomping on him

Ash made the right decision to leave a girl like that

This wizard is such an idiot! He made marceline suffer...she's like a daily cuddle to me so it hurts me so much to see her crying

He was sold Marceline's teddy bear Hambo. - 05yusuf09

34 Starchy

Another creepy pervert that speaks in third person.

Starchy is an idiot!
Starchy is a freak!
Starchy is a pervert!
He committed adultery!

35 Queen Bee

Or maybe he probably thought the female bee was buzzing around Finn's flower arm (he lost his right arm 3 episodes before Breezy) and she turn into some kind of queen. He coulda put Breezy's name instead of Queen Bee.

Are you dumb Queen Bee is a character from Super Mario Galaxy NOT adventure time

Correct, Queen Bee is a character from Super Mario Galaxy but there is also a queen bee in adventure time - SheepBuggy

Her name is breezy. Who's the noob that wrote this thing?

I never put that on there, some idiot did. - NerdyPweeps

36 A Fox

I love mr fox!

I hate mr fox!

37 Lady Rainicorn

She speaks Korean, idiot. Learn basic stuff. You're racist, it's not crap. You're crap

That racist you idiot

This is racist. Rainicorn speaks Korean, not crap you idiot.

Why are you hating on Koreans? They're human too and that's prejudice. Lady is not intended to have an ethnicity because she's a MYTHICAL CREATURE.

38 Benson Benson Dunwoody is a main character on Cartoon Network's Regular Show. He is a gumball machine, also known as The Park's manager. As the manager, he is the boss of every park worker (with the possible exception of Pops). He has a short temper and has a tendency of yelling at Mordecai and Rigby every ...read more.

Benson is Regular Show not Adventure Time

39 Melissa

Who's Melissa?

40 Dr. Gross

She weirds me out. Also her design ripped off Nebula. - 445956

41 The Lich The Lich (formerly named the Lich King in the original pitch and "His Hero," and referred to as Sweet Pig Trunks in his baby form, or just Sweet P for short) is a powerful undead being and a major antagonist in the American animated series Adventure Time.

You can tell this guy was inspired by the Horned King judging by his design.


Is the worst character

Is the best character

43 Snail

Yes he is the worst character

No he is best character

44 Lemonhope

Boring character

45 Beth

Beth is such boring character only interesting part Is when she ejects stuff out of her belly button because it's a bit satisfying but cringy at the same time

Also known as 'Betony Burrito Jakson IV', Beth is a descendant of Jake and Lady Rainicorn who was born as ruler of the pup kingdom but got exiled for reasons and became fugitive to the kingdom.

Boring character

46 Jake

Not a bad character, but not on the list.

Who put Jake on the list? - 05yusuf09

Boring character

Remember that episode where he spent all of their gold in one unnecessary useless scenario? Jon Dimagio sure has a talent for playing bad roles. Bender is easily my least favorite futurama character. He has about the same significance as Jake. Which is none.

47 Shelby

Shelby sucks because he's a worm
And worms are gross

48 Prismo

Why is he bad exactly? - SammySpore

This guy is so much fun! It sucked wnen he had died. I don't know why he is on this list!


Awsom charecter number 1. for me

49 Vampire King

I was hoping Marceline would get to fight him but the ending was good but he kinda ruined it he was boring and gave up to easily

50 Flame Prince
