At first, Laughing Jack was an innocent, sweet, and pure-hearted angelic creation who tried his best to comfort children, considering how lonely they were. However, the children's late actions significantly affected in a particularly negative way the gift, which became more and more disturbed and psychotic with time; Laughing Jack, originally colored, lost his hues as Isaac's actions corrupted it. Eventually, Laughing Jack became totally black and white, as he reached a point of non-return and fully embraced his demonic form. Currently, Laughing Jack presents itself as a figure of pure evilness, remorseless and violent in its very core, who take pleasure in killing and torturing those he was once designed to protect children. Laughing Jack is a magical being, with incredible dark magical powers, being able to teleport in an instant in a puff of pitch-black smoke, turn himself invisible, and being able to mutilate the bodies of his victims. Jack is also able to create nightmares and visual hallucinations, presumably to parents, such as he did in the original story, and can use telekinesis to move objects with his mind, making his victims seem crazy. Laughing Jack used to be a colorful, tan-skinned clown who would wear a brilliant rainbow attire with shaggy red hair and a long cone nose. After being abandoned for 13 years, his appearance changed to being completely monochrome, leaving him almost demonic-looking. Created by a guardian angel, Laughing Jack was initially a colorful Jack-in-the-box clown whose personality reflected the personality of his owners. He was later sent as a Christmas present to a lonely boy named Isaac Grossman in the 1800s. Isaac then abandoned Laughing Jack after being sent to boarding school. Laughing Jack grew monochrome and emotionless as a result of his isolation. Meanwhile, Isaac grew up to become a cold-hearted serial killer who kidnapped, tortured and murdered several innocent neighborhood residents. Although horrified at first, Laughing Jack's personality soon emulated Isaac's evil personality. One day, Laughing Jack was accidentally released and he appeared to be a taller, darker and demonic version of himself. Resentful of his traitorous owner, he tortured and killed Isaac. As time passed, Laughing Jack visited several other children, most of them lonely or neglected, and pretended to be their imaginary friend. However, he would eventually torture and kill them all, with their souls trapped in the nightmarish realm of an abandoned fairground. To make matters worse, the song "Pop Goes the Weasel" plays in the background forever, tormenting them.
