Spider-Girl
Spider-Girl (May "Mayday" Parker) is a superheroine in Marvel Comics' MC2 universe. The character was created by Tom DeFalco and Ron Frenz as the teenage daughter of Peter Parker (Spider-Man) and Mary Jane Watson, and first appeared in What If (vol. 2) #105 (February 1998). She later acquired her own ongoing comic book, Spider-Girl, written by DeFalco and drawn by Frenz and Pat Olliffe, which was the longest-running superhero book with a lead female character ever published by Marvel before being relaunched as The Amazing Spider-Girl, and later The Spectacular Spider-Girl. Peter and Mary Jane named their daughter after his Aunt May.
