Mattie Dearden was an obsessed Spider-Boy fan who became enraged when the young hero announced his engagement to Insect Queen. Believing that nobody could love Spider-Boy but her, Mattie took five magical coins from a museum and used them to give herself superhuman strength, superhuman speed, the ability to fly, enhanced senses, and the power to fire electrical blasts from her fingertips. Creating a costume, she took on the identity of Araniella (the name of a genus of orb-weaving spiders) and tried to prove that she was Spider-Boy's prefect mate. When he rebuffed her advances, Araniella attacked Spider-Boy before faking her death in the ensuing battle. However Araniella still believed he truly loved her and returned several times to win his heart, much to Spider-Boy's chagrin.
