>>109068595Yes and no. All of these characters have to do with bad ends or twisted forms.
>MarcoNot sure why, but the artist used his costume from "Blood Moon Ball". The actual episode has nothing to do with him being evil.
>DipperIn "Sock Opera", the antagonist Bill Cipher offered a trick favor onto Dipper in order to possess his body and take one of the journals from Mabel. He was canonically called "Bipper" and was a fan favorite.
>FinnIn "Finn The Human" and "Jake The Dog", Finn got a magical wish where he wished the Lich never existed. He was transported into a human-like AU of Ooo where he eventually finds Simon's corpse with a crown on his head. Not knowing the crown was evil, he became mentally insane and destroyed the AU's world.
>WirtHaven't seen the show in a long time but this relates to an AU where Wirt becomes possessed by The Beast.
>MortyAn alternate Morty in the multiverse was revealed to be evil in the episode "Close Rick-Counters of the Rick Kind" and having the iconic design of an eyepatch on his eye.
