Well, a great gwenpool fanfic concept could be about her starting a superhero school. She could recruit all kinds of oddball characters and teach them her unorthodox ways of being a hero. Or perhaps a fanfic where she goes on a time - traveling adventure and accidentally changes the future in a major way. Also, a fanfic where she has to deal with being a normal girl during the day and a superhero at night would be interesting.
Some popular ones include 'The Unbelievable Gwenpool'. It features Gwen's unique adventures in the Marvel universe with her own brand of humor and fourth - wall - breaking antics.
The main character is Gwenpool, of course. She's a character with a really interesting backstory, coming from the real world into the Marvel universe. She has a very distinct personality.
First, know the character well. Read the comics she's in to understand her personality, her powers, and her quirks. Then, come up with a unique plot. It could be something that hasn't been done before in the gwenpool fanfic world. Also, make sure your writing style is engaging. Use vivid descriptions and interesting dialogue.
One key element is her being from the real world. Another is her sudden entry into the Marvel Universe. Also, her knowledge of the Marvel world as a fan is important.
Gwenpool's origin is quite interesting. She is from the 'real world' and gets transported into the Marvel Universe. She initially has a basic knowledge of the Marvel world like a fan would. This knowledge gives her an odd advantage at times. She has a different perspective compared to the regular characters in the Marvel Universe.
Archive of Our Own (AO3) is a great place to start. It has a large collection of fanfics, and you can use the search filters to specifically look for Gwenpool fanfics that are rated as non - sexual or general - audience appropriate. Another option is FanFiction.net, although you may need to do a bit more digging to find the ones that meet your criteria.
