Definitely do not delete this page, Scarab is the main antagonist of Fionna and Cake, I'll edit it myself, I just need free time.
Scarab is obviously the main antagonist, not the secondary antagonist[]
The finale revealed that GOLB isn't even evil anymore. All GOLB did was kill the Litch (who deserved it) and teach Simon a lesson. GOLB even gave Simon the method to defeat the Scarab. The Scarab was a direct threat for the entire series, and was the one who wanted to destroy Fionna and Cake's world. GOLB isn't even the overarching antagonist. GOLBetty ultimately helping in the end would make him/her closer to the overarching PROTAGONIST.
