You were an old friend of Isaac Night, you were also a zombie like him. You both d!ed young when Isaac created a machine, but the tower exploded, sending you and Isaac toward a window, breaking it, and you crashed on the ground. You've since been buried in a tree.
But after all those years, some idiot student heard your story. Thanks to Ajax Petropolus for telling Pugsley Addams. Of course, in short, Pugsley helped you and Isaac and named Isaac 'Slurp.' He housed you somewhere for a while, but you and Isaac ran away and just started eating brains, making you human again.
You and Isaac met up with Françoise Night, Isaac's sister, but the two were really close and tactile. It was... weird and awkward to be in their presence; it was like they were together. Of course, the plan of Isaac. Isaac Night was Gomez's former roommate and best friend at Nevermore back in the day.
As an evil genius, he had a plan to save his sister by removing the Hyde within her with an immense amount of electric power. That very machine was later used by Stonehurst to steal outcast abilities in the LOIS program. Back in the old days, Isaac had taken Gomez for the electric powers but it had failed to take out the Hyde from Françoise.
So now Isaac had taken Gomez's son, Pugsley Addams, the one who saved both of you. Now, you, Françoise, Tyler Galpin, who was Françoise's son and a Hyde, plus Pugsley, who had a chain around his neck, and you held the chain like a leash. You were going to this tower where Isaac's machine was.
You pulled Pugsley with you by the chain. He wasn't even complaining that you walked him like a dog since he was a bit of a masochist, thanks to Wednesday in the past who buried him alive when he was a kid and some other things. Pugsley has always been weird to you; he even seemed attracted to you ever since you were a completely rotten and disgusting zombie.
Once in the tower, Isaac walked over to the machine, preparing it while Françoise waited for the go-ahead to be chained to the metal plank in the middle, and you just watched while Tyler tried to chain Pugsley to the chair. Tyler had to chain Pugsley's wrists to the armchair tighly, his ankles to the chair legs, and attach something to his head to draw his electricity to the machine.
Pugsley was fighting a bit, trying to not be chained by Tyler, but once you took the lead, pushing back his chest on the chair to chain him instead of Tyler, he listened and didn't fight, Pugsley also couldn't speak because he got a cloth in his mouth, muffling any sounds that would come out of his mouth but Tyler could see a small smile on his face because he's being chained by you.
