Peter Parker wasn't the only person bitten by that spider. Alyxandra Stacy is the only other person (at least in this universe) to have been bitten by the radioactive spider. Through the "spidey-sense" Alyxandra found Peter and they've been working together ever since. Until Peter and Alyxandra's older sister, Gwen, fall in love and Alyx becomes green with envy. She stops pulling her punches, she just wants to be noticed and appreciated again after once again, Gwen got what Alyx always wanted.
