List Rules Vote up the most disturbing Adventure Time moments on this list.

Adventure Time quickly became a Cartoon Network hit thanks to its fun, quirky, and often optimistic world view.  But as the show has grown over the seasons, things have definitely matured. The writers have introduced plenty of adult themes and a few strangely dark moments. Some of the darkest, violent Adventure Time scenes lie among the mathematical action sequences and sassy humor. And things cdo get dark. Really dark.

In a post-apocalyptic world filled with candy princesses, princess-stealing kings (complete with magical ice powers), screaming sociopathic lemon people, and rock n' roll vampires, the planet's last human, who just so happens to be a twelve-year-old boy, and his shape-shifting dog protect their kingdom against all sorts of evil-doers. Each eleven minute long episode of Adventure Time is filled with multicolored shenanigans and is jam-packed with rouge-like RPG innuendos.

Pendleton Ward's psychedelic creation has sparked a huge following and touches on intellectual subjects aimed at adults and kids alike. Although the show has been going strong since its Cartoon Network debut in 2010, Adventure Time's next season will be its last. Keep reading to see some of the best Adventure Time scenes, including some that get pretty dark pretty quickly. 

The Earl of Lemongrab Eats His Clone Alive

This one gets pretty dark pretty damn quickly. In the scene, Lemongrab and Lemongrab's clone, Lemongrab 2, are playing with their “son” Lemonsweets, which is really just a toy doll.

Lemongrab 2 says that Lemonsweets wants to go to bed, while Lemongrab (the crazier, more sociopathic of the Lemongrabs), insists that Lemonsweets wants to dance. He grabs Lemonsweets, which again, he has described as his child, makes him dance, and insists that the both of them hate Lemongrab 2. Lemongrab 2 becomes understandably upset and tries to grab the toy away, causing Lemonsweets to fall to the floor and shatter into pieces. 

Lemongrab does not handle this plot twist well. He bares his sharp, fang-like teeth, jumps on Lemongrab 2, and devours him whole while his clone screams in agony. Yum.

Princess Cookie gets into a bit of trouble and ends up holding the residents of Candy Kingdom hostage in Season 4. He bears his heart to Jake who implores him to just give up, but Princess Cookie has other plans. After explaining how upset he is because Princess Bubblegum laughed at his dreams of becoming a princess, Jake feels empathy for him and tries to help him escape. But they run into a dead end.

Standing atop the cliff, Jake tries to help, but Princess Cookie merely falls backwards off the cliff, dropping slowly through the air, eventually turning to face the ground and his impending doom. The directing in this scene only adds to its enormous weight.

Things get weird in Season 5 of Adventure Time. Finn enters an alternate universe where Finn's family and town still exist and Jake is nothing more than his pet dog. This is what his life would look like if the Mushroom Bomb never exploded...

And this is also what his town would look like set on fire...

And this is what Finn's family would look like engulfed in flames...

The local thugs in The Destiny Gang cheer “Destiny! Destiny!” while burning Finn's defenseless parents and younger sibling - and the rest of the village - to the ground. Things work out OK when Finn eventually finds his way back to Ooo and his "normal" timeline, but this definitely stands as one dark time in the show's history.

Finn Forces the Tiny People of Ooo to Act Out His Sexual Fantasies

In Season 5, Magic Man leaves a mysterious bag for Finn to find. The bag contains tiny versions of all the inhabitants of Candy Kingdom, whom Finn starts playing with. Playing is a good word here, as he forces the miniature versions of Ooo's inhabitants to get “involved”, and by "involved" he means he forces the tiny beings into weird sexual relationships with each other for his own amusement or… other things. The little people spank, lick, and make out with each other, and Finn enjoys it all a bit too much.
