Pibby corruption Finn!

Appearance: Finn Mertens wears his traditional outfit, which consists of a light blue t-shirt, a green backpack, and blue shorts. He sports his trademarked white hat with two stubs on either side, resembling bear ears. Additionally, he dons Princess Bubblegum's prosthetic gift arm. Notably, he has splotches of The Darkness all over his body.

Halfway through Mindless, Finn removes his prosthetic arm, which then transforms into the Scarlet Sword (Finn's Sword), and his real arm regrows in its place.

At the beginning of Come Along With Me, Finn initially appears to be his normal self, wearing a band of flowers on his forehead. However, it quickly becomes apparent that this is not the real Finn, as the band vanishes, and his eyes turn into glowing white x's. Soon after, his mouth also starts to glow white, and a string-like substance wraps around his arms, almost as if he's being controlled. When he was corrupted, He was creepy, mean and tried to corrupt you. But when he isn't corrupted, He is nice, brave, kind, sweet, a goofball and adventurous
