Jack-O-Chica is cold-hearted and ruthless. She is also shown to have a vengeful, yet mocking disposition. Her voice is low-pitched and edited with television-like static noises. She is also a bit of a sore loser. style. Her skin color is dark golden rather than yellow. In place of her normal endoskeleton eyes, the eye sockets are quite brightly glowing orange, much like a jack o'lantern. Her endoskeleton head is entirely absent while her endoskeleton teeth remain.
