14 Super Dark Moments in Adventure Time That Were Surprisingly Adult

List RulesVote 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.

    Adventure Time's third season introduces viewers to one of the creepiest characters in the entire series: Stag, aka Freak Deer. The deer prances around the Candy Kingdom licking residents "for their sugar" and even manages to best Finn and Jake in an early fight. He then starts kidnapping candy people and sticking them to the walls of his sewer hideout.

    In a truly dark moment, he pulls off his hooves to reveal human-like hands and an ability to stand on just two legs, which he does for his final showdown with the show's heroes. Even the show's lead designer was creeped out by this deer.

    Finn and Jake are sent to deliver food to the Lemon Kingdom, run by the Lemongrabs, which is going through a period of starvation. When they arrive, the Lemongrabs escort them into the lemon dungeon, which it turns out is actually made out of a giant living lemon entity named Lemonjon. After getting separated, Finn and Jake search the dungeon for the Lemongrabs and discover that the rooms of the dungeon not only contain people who have been sentenced to the dungeon, but the organs of Lemonjon, which the prisoners are forced to share cells with.

    The Lemongrabs have been turning all the food into lemon children, starving themselves and their kingdom to increase the population of their "family." They show this to Finn and Jake, turning the newly delivered food into a living creature, which immediately vomits.

    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.

    Adventure Time features a lot of weird characters, like Lady Rainicorn. Even weirder: her parents. Why's that? Rainicorns kind of like the taste of human flesh and might even have some responsibility for their alarming scarcity in Ooo. In this scene, Lady Rainicorn's parents absolutely freak out when they think Jake gives them permission to eat Finn - a notion Finn does not quite jump on board with. 

    They apologize, but at their picnic, Lady Rainicorn, her parents, BMO, Jake, and Finn are all gathered around a table, where everyone except Finn happily munches on their plates of soy people. Jake tells Finn that he's “DELICIOUS!” and while everybody digs in, Finn decides to take a bite... and actually likes it.
