Alexander Hamilton was a ghost, who haunted a graveyard on one Halloween.
He's a ghost who is able to travel through objects, and he is only able to touch candy. He is reanimated every Halloween but is unable to leave the graveyard where he was buried.
History[]
He was blocking Bat Man's path. Bat Man was able to get past him. ("Halloween Special 2021" - "Second Game").
Later that same Halloween, he managed to escape the graveyard with the help of Bones. He haunted a house, and when trick-or-treaters stopped by, they would either get some candy or lose some - since Hamilton would steal it. ("Halloween Special 2021" - "Candy Crunch Time").
Even later that day, he approached another house. All he wanted to do was trick or treat there and taste candy like a human so he could be happy. Unfortunately, he decided to pick the house where Bat Man lived and, aided by a boy named Will dressed in a Dracula costume and a slime named The Brewer living under Bat Man's house, he managed to convince Bat Man to give him a Twix bar and a bag of Skittles. He tasted the candy and he was so happy that he returned to the graveyard. ("Halloween Special 2021" - "Fourth Game").
