What Makes Him a Shonen Villain?[]
- Villainous: Has sent hostile pumpkins to ravage Endsville, caused destruction in terrorizing Endsville and seeks to behead Grim with the Scythe and stay dead forever.
- Skillful: Is a professional prankster who lived in Endsville around the medieval 16th/17th century and knows every trick in the book.
- Power-Hungry: Obtained Grim's sycthe if it means granting him more power than ever, also he made a deal with Grim to be granted immortality if he gave back Grim's sycthe before he was decapitated.
- Pursues a Big-End Goal: Seeks to control the universe.
- Arrogant: When he became a villain especially, he often acts smug, cocky, conceited and enjoys taunting anyone who tries to outfox him.
- Intelligent: Is so smart that he can trick and outsmart anyone he comes by, especially when he regularly plays tricks on others and when he first thought Billy's sycthe was fake, once he founded out Billy was carrying Grim's actual sycthe everywhere he goes, he saw purpose in manipulating Billy into falling for Jack's feather assault trick and also tricked him into being friends so he can release deadly spirits to cause trouble and havoc to Endsville as his elaborate plan of revenge, to of which he succeeded at.
- Cold-Hearted/Ruthless: While he does have a tiny bit of tragedy due to his tragic backstory, Jack has become merciless enough to cause misery to anyone in Endsville.
- Short-Tempered: Jack can get angered, especially when Billy was twerking as a way to distract him from killing Grim with a scythe.
- Sadistic: Jack has shown to be a sadist with his pranks that became much more mean-spirited than before, especially the prank where he puts a whoopie cushion in a tomb to make people laugh during a memorial and changed a road signal that caused a traveler to fall off a cliff.
- Tragic Past: He was killed by Grim just for being a prankster who annoyed other people, and got beheaded and had the Queen to order his execution just for his pranks and nothing else major.
- Laughably Evil: A lot of Jack's humorous moments comes from his exaggerated snoring, finding the humor in anything such as making silly head puns/idioms at Grim's expense, and how he has frustration with shopping due to his appearance.
