Debra Whitman

Debra Whitman is the "little sister" Peter Parker never wanted. They both go to Empire State University and work for Dr. Curt Connors. Debra is just as smart, possibly smarter, than Peter and maintained a friendly rivalry with him. She developed a crush on Michael Morbius, though he showed interest in Felicia Hardy. She also had a crush on football star Flash Thompson and he eventually returned them making a relationship. After Morbius disappeared she began to party, so much that even Flash felt they should study instead. Eventually Debra went back to her studies after she helped Mary Jane Watson and Martha Connors use the Neogenic Bomb to stop Lizard and save Spider-Man.
