Peni was introduced into the spider-canon in 2014 via the one-shot Edge Of Spider-Verse #5. After an accident kills both of her parents, she's adopted by May and Ben Parker. It then turns out that her parents, as well as May and Ben, had been working with the government to create SP//dr and, whoopsie-doodles, it turns out that Peni is the only one who can control it. And by "it," we mean the radioactive spider locked inside SP//dr, which both powers the robot and does the actual work of controlling it. In order to talk to this spider, however, Peni first has to establish a psychic link with it ... which she can only do by letting it bite her.
