Finnceline

"I, for one, think you're pretty great."

- Marceline to Finn in "Go With Me"

Finnceline is the het ship between Finn and Marceline from the Adventure Time fandom.

Canon
In the episode "Evicted!", Marceline was messing with Finn by making herself look evil. After she got punched by Finn, she said "That actually hurt, Finn", then shapeshifted back to normal form, and kissed Finn on his cheek.

In the episode "Henchman", A rowdy and adventurous character, Marceline and Finn share the same vigor and thirst for danger. One of the key reasons why they managed to forge a friendship is that Finn saved her life in "Henchman" when Jake exposed her to direct sunlight and threw garlic at her in a misguided attempt to save Finn. In the same episode Finn, in an attempt to convince Jake of her generally wholesome ways, calls Marceline "a radical dame who likes to play games."

In the episode "Go with Me", Finn was trying to hang out with Princess Bubblegum. Marceline gave Finn some bad ideas and caused Bubblegum to banish Finn. When they were at the treehouse, Marceline said sorry to Finn, kissed him on his cheek, and then flew away. After that, Finn decided to ask Marceline to the movie, however, Marceline thought he was trying to date her, and said she didn't like Finn romantically. After Finn explained that he just wanted to watch movie with her, she accepted.

In the episode "Marceline's Closet", that Marceline still hides out in Finn and Jake's Tree Fort from time to time. In the same episode, Finn sees Marceline naked as she is about to take a shower, resulting in Finn being very flustered. Also, in the episode, Marceline forgives them for sneaking into her house even though she says not to.

In the episode "Heat Signature", she pretends to turn Finn and Jake into vampires and laughs at them when they think they're actual vampires. However, when her ghost friends start taking it seriously and actually hurt them, she intervenes and confesses she lied, apologizing and showing that she actually cares for the two.

In the episode "Daddy's Little Monster", Marceline's father states that he thinks that her friends, meaning Finn and Jake, are OK. After hearing this, she jests to Finn that she doesn't want to hang out with him anymore.

In the episode "Bad Little Boy", Marceline tells a story centered on the interaction between her male-counterpart, Marshall Lee, and Finn's female-counterpart, Fionna. It is possible that she based the story on her own interaction with Finn. Even though Marceline claimed she only likes Finn as a friend, Marshall Lee seemed to think Fionna liked him more than that. It is also possible that Marceline wrote it as a love story only to please the other princesses, but the former statement could hint at Marceline's feelings for Finn.

In the episode "Simon & Marcy" marks the first time since "Daddy's Little Monster" that Marceline has hung out with Finn (not including "I Remember You"). She shows that they still have the same friendship they did in previous seasons, backing up that she was only jesting about not wanting to hang out anymore.

In the mini-series, "Islands", Marceline shows up to wish Finn and Jake goodbye before they embark on their trip, and states that she and Bubblegum care for him.

Finnceline was once drawn in Rebecca Sugar's concept art, who came up with the idea of Bubbline.

Fanon
