Sure thing. Peter Parker is a classic comic book character. He's had countless issues and story arcs dedicated to him, making him an icon in the comic book world.
Peter Parker's age varies throughout the comic book series, but he's typically depicted as a teenager when he first gains his powers and then progresses in age as the storylines unfold.
There were many endings for Spider-Man Peter Parker in comics, but the most common one was that he was attacked by poison and eventually sacrificed. The venom transformed his body into its own host, becoming the new Spiderman. But there are other endings like Peter Parker dying in some accident or he's still alive but in some kind of predicament.
In fanfiction, Peter Parker's age can vary widely. Some fanfics might keep him at his traditional comic or movie age, like a teenager in high school, around 15 - 18 years old. This allows for stories centered around his high - school experiences, dealing with bullies, and his early days as Spider - Man.
