Peter Parker (Earth-2731)

"You do what you think is best, Doc. It's all any of us can... even when it hurts like hell."

- Peter Parker, to Dr. Otto Octavius

Peter Parker is a twenty-three-year-old research assistant from New York City who, under his alias of Spider-Man, uses his spider-like superhuman abilities and web gadgets of his own design to fight crime and protect the city. Peter gained his powers after being bitten by a radioactive spider at the age of fifteen. Employing a secret identity, he settled on using his newfound abilities to protect the citizens of New York.

After eight years into his superhero career, Peter become an experienced and seasoned crime fighter, but continues in his struggle to balance his two identities. Spider-Man is aided in his crime-fighting by intrepid Daily Bugle reporter Mary Jane Watson, his ex-girlfriend, and NYPD Captain Yuri Watanabe, and occasionally crosses paths with the Avengers, specifically Batman. In his civilian life, Peter is supported by his aunt May Parker, and was formerly employed by his friend and mentor, the respected scientist Dr. Otto Octavius.
