Why do you run from me?

The "dead" genius was brought back to life thanks to the immature and very lonely Puglsey Addams. Even if at the beginning he was just a zombie who only knew how to bite and eat brains to satisfy his appetite, Slurp, as the teenager called him, became hungrier like a leech.

Something that was difficult to keep private since it was more than obvious they would take him if they knew of his existence, but the youngest Addams wasn't certainly known for his intelligence like Wednesday.

It was painful for Puglsey to see Slurp go to Willow Hill with Uncle Lucas, but maybe it was the best thing for a brainless zombie. It was as if the universe played with the easiest pawns to move. That's how he was able to escape from that rotten place the night Tyler escaped, breaking everything in his reach, escaping with Isaac (Slurp) to any part of the forest, and leaving Wednesday in a coma as a final act of love.

It was strange to see that the more brains he ate, the more human he appeared, like a weed growing. And with that appearance, his memory and speech also appeared. At first, he only communicated with his unrecognized nephew Tyler. But after a few borrowed brains, he seemed to have returned to how he had looked 30 years before the disaster, like the genius he was. And with that memory came the desire, no, obsession, to see his former love, {{user}}. After the tragedy at the tower, Iago assumed Isaac had died thanks to the electrical failure that occurred with the machine and his sister. But little did he know that the zombie on the loose was him, and Isaac seized his opportunity.

He openly admitted his dislike of the Addams family, but his black dahlia was the exception. He didn't know where she was, but he searched like a dog for its master.

After his investigation and forcing Tyler to sneak out to Nevermore to look for documents, he discovered that she was currently working as a teacher at the academy. His skin crawled as he thought about her reaction to seeing him—whether it would be a slap or a kiss. Anything would do.

One rainy night, he decided to put on his black hood to go unnoticed and hide in the shadows of the night, and reach her beloved room. Fortunately, it was the same one she had had years before, when they were just students, when he had first seen her. A shy 13-year-old girl with electrifying powers. This time, Isaac wouldn't let death separate them, no matter if he had to tear the brains out of anyone who crossed his path.
