A cool plot could be that Daredevil mistakes Hawkeye for an enemy at first. Because of Hawkeye's skills with a bow and arrow, Daredevil might think he's a new assassin in town. But then they realize they're on the same side when they both target the same group of bad guys. They then combine their abilities, like Daredevil guiding Hawkeye's arrows in the dark using his enhanced hearing.
One idea could be a team - up where Spider - Man and Hawkeye have to stop a group of villains who are stealing high - tech weapons.

Or perhaps Daredevil's legal knowledge helps the Avengers deal with the political fallout of one of their big battles.
A plot could involve Peter's identity being at risk and Daredevil helping him keep it a secret. Since Daredevil is so good at operating in the shadows, he could teach Peter some new ways to move around the city without being detected.

A plot could involve Spiderman getting framed for a crime in Daredevil's territory. Daredevil initially suspects Spiderman but as he investigates, he realizes that there's a bigger conspiracy at play. They then join forces to clear Spiderman's name and expose the real culprits.

Perhaps there's a situation where a powerful criminal organization has a device that can scramble Daredevil's senses and Spiderman's spider - sense.

Another plot could be set in an alternate universe where Supergirl lands in a world that has no concept of superheroes. She has to learn how to fit in while also trying to figure out how to use her powers without causing chaos. The fanfiction could explore her journey of self - discovery in this new world.
