In 1984, Marvel Comics created a new nemesis for Spider-Man. The character would be a symbiote, inspired by what parasitologists call the weaker of two organisms inhabiting the same space. The weaker organism can draw life from the stronger, and in the most dramatic cases it siphons off its host’s nutrients before the host realizes what’s happening.
