Cousin Vlad is a relative of The Addams Family.
The playboy first cousin to Gomez and Fester, he was one of the Addams' finest -- loathsome, sadistic, duplicitous, insidious, and a real ladies man. Vlad was also an expert marksman. As a child, he had a summer job as an executioner. And he was also called "Mr. love 'em and leave 'em. People magazine's shiftiest man alive". He and Morticia were quite an item, and he and Gomez fought for Morticia's love, until Vlad choked on a toothpick and died. That was 13 years ago and he was buried in the Addams graveyard. His funeral immediately preceded Gomez and Morticia's wedding ceremony. Wednesday resurrected Vlad and subsequently returned him to the dead as a lich (similar to a zombie, but smart enough to know who and what it is and remember its human life). He attempted to kill Gomez repeatedly.
While Fester, Wednesday and Pugsley asked Grandmama for a spell to put him back to death, Gomez and Vlad continued their fight. Wednesday finished the spell, and Vlad turned to dust.
