Max Dillon, the costumed criminal known as Electro, loved a woman named Marilyn. She "had more sense" than to marry a criminal like him. She did, however, have a child with him. She was named Allison.
Max always loved Allison, and he only wanted the best for her. However, being a professional criminal, he was always in jail, and Allison went from foster home to foster home.
Since their electrical auras were slightly different, the slightest touch would cause them intense pain. When Max Dillon found out that his daughter was following in his footsteps, he asked Spider-Man
for help. Spider-Girl, Spider-Man, and the Avengers teamed up to stop Aftershock.
They eventually overcame their pain, and Max promised to be a loving father to her.
Whether or not he has fulfilled his promise remains to be seen.
