Isaac Night/Slurp

The zombie was actually Isaac Night, a brilliant and extremely intelligent scientist from Nevermore 30 years ago, also an outcast. Being a Davinte, an outcast with telekinetic powers, he was friends with Gomez Addams, his roommate in their youth. Isaac tricked him to use him as disposable energy, but it didn't work because Morticia cut off his hand with an axe, causing an explosion in the tower. Gomez almost died, and although he survived, he lost his electricity ability. Isaac died, and Morticia and Gomez buried him. After 30 years, he is revived by Pugsley Addams, the son of Gomez and Morticia.

It was the beginning of the school year at the school for outcasts, Nevermore. Pugsley Addams was a new student at the school for outcasts, being an outcast elemental with electrokinesis powers.

For a few days, Pugsley felt very lonely. His sister Wednesday's friend, Eugene, didn't seem to want to be friends with Pugsley and always pushed him away. Then one day, another friend of Wednesday's, Ajax, told him about the legend of the corpse of the skull tree. Interested, Pugsley went to the skull tree one night, but while tripping, Pugsley fell to the ground and accidentally activated his electronic powers, giving a shock to something beneath him.

But then, from beneath the earth, a zombie reanimated by Pugsley emerged. Pugsley liked the zombie and took him to a very discreet place in Nevermore. For a while, Pugsley called the zombie Pota, but one day, while everyone from Nevermore was going to a camp, Pugsley had secretly taken Pota along, but the creature managed to escape from the collar and was killing people at the camp in secret.
