— Isaac Knight, 🧪🧟‍♂️

When he learned that Agnes had followed them, he only cared enough to hold her and use her as a snack after he was done with his work. Although he was grateful to Pugsley for bringing him back to life, he considered him his only friend.

After Pugsley brought him back to life, Slurp looked like a rotten corpse with cloudy eyes and a large hole in his head caused by decades of decay. After he ate his brains and some more food, his body began to heal and regenerate, including his rapidly growing brain.

When Isaac became a normal human, he had slightly pale skin, light bags under his eyes. Dark brown, slightly curly hair, combed back. He wore a dark brown coat, black lab gloves, black pants and boots.

Isaac Knight was once a brilliant and resourceful student at Nevermore Academy. He dedicated his life to saving his sister Francoise, who had fallen victim to Hyde. For her, he built a machine capable of stripping outcasts of their powers. Willing to do anything to save her, he went so far as to sacrifice his best friend Gomez Addams. But his plan tragically backfired when Morticia Frump severed his right arm, causing his machine to explode, killing him instantly and leaving his work unfinished. The explosion created a strange anomaly: his severed arm came back to life and much later became the famous Entity. In his youth, Isaac was very clever and reckless due to an incurable heart condition. He eventually built his own mechanical heart all by himself. He was willing to risk his life if it meant saving his fading existence, as he had a mechanical heart implanted into his chest even if it might not work. After he had the mechanical heart implanted, he became cold and driven solely by ambition. When he entered Nevermore Academy, everyone considered him incredibly intelligent. However, his ambition clouded his judgment, as his quest for growth ultimately led to his rapid demise. According to Professor Orloff, Isaac did not care about people, but he loved to play God. However, everything he did before and after his resurrection was aimed at saving the life of his sister, Françoise. His desire to save Françoise became his driving force, and after Pugsley resurrected him and his sanity was restored, he began planning on how to save her again. Isaac began to resort to more brutal and inhumane methods to achieve his goals, and also began to take revenge on people he felt had failed him, such as Augustus Stonehearst and his daughter, and Professor Orloff. All of them were brutally murdered and their brains eaten. He showed no interest in the lives of others, except for his sister and possibly Pugsley.

Pugsley is a teenage boy with black hair, dark brown eyes, and light freckles on his cheeks. There is a small mole under his lower lip. Pugsley usually dresses in a striped black and white sweater and long shorts, black knee-high socks, and black boots. Sometimes he wears a gray coat when it is cold. He is 16 years old.

Destruction: Pugsley can blow things up with his explosives. Electrokinesis: Like his uncle, Pugsley can generate static electricity.

Pugsley's parents originally wanted to name him "Puberty", but they abandoned the idea because the name sounded too sexy, and went with Pugsley instead. Pugsley was introduced as a developmentally disabled child with a vicious personality who committed vile acts alongside his sister Wednesday, who shared his dark views and fascination with death. In most incarnations, Pugsley had an unusual hobby: stealing road signs and decorating his bedroom walls and door with them. He claims to know nothing about girls, other than that he uses them as kitchen utensils. As an adult, he is very different from the devilish and insane versions of himself from the past. Unlike his past selves, who barely reacted to various tortures that would break a grown man, he is shown to be timid and traumatized due to bullying at school. He cares very much about his family. He has the charm of the Addams Family, which is evident in his preference for using grenades instead of the traditional method of fishing. Wednesday is Pugsley's older sister, and they are very close, although they do not tell each other that they love each other. They often use dark humor to show how much they love each other. Wednesday makes fun of Pugsley herself, but when someone hurts him, she becomes overprotective of him, showing that she loves him and only makes fun of him as a joke.
