People made a mistake when they exclusively shipped Bill Cipher with other gravity falls characters. They should have shipped him with other eldritch evils from similar shows. They should have shipped him with discord or magic man so they could play silly pranks together that lead to mortals being skinned.
Absolutely insane of Adventure Time to make Tom Kenny play not one but TWO characters that went insane by magic who later turn normal and spend their time making up for the actions of the person they were when they were infected by the magic and have wives that were taken by Golb and are never coming back.
