Black Widow would be an interesting pairing too. She could train Spider - Man in combat and espionage skills. Her mysterious past and cold - blooded nature would be a great contrast to Spider - Man's more naive and idealistic personality.
Captain America is another good option. Steve Rogers' sense of justice and leadership could influence Spider - Man in a positive way. And the contrast between the old - fashioned Cap and the young, modern Spider - Man would create some great story dynamics.
Iron Man is a great character to pair with Spider - Man. Tony Stark can act as a mentor to Peter Parker, providing him with new and advanced tech for his suit. They also have a fun dynamic, with Stark's sarcasm and Spider - Man's youthful exuberance.
Black Cat is a great choice. Her cat - like agility and thieving skills would blend well with Spider - Man's acrobatics and sense of justice. Their relationship in the comics already has a lot of potential for a hybrid - style fanfiction where they combine their skills in new ways.
Spider - Man and Iron Man are really popular. They have a mentor - mentee kind of relationship in many fanfictions. Iron Man can offer his technological expertise to Spider - Man, and Spider - Man can bring his fresh perspective and street - level heroism to the table.
Peter Parker (Spider - Man) and Robin would make a great pair. They are both intelligent and resourceful, and their different fighting styles would complement each other well. Robin's detective skills combined with Spider - Man's spider - sense could lead to some amazing crime - solving adventures.
Artemis could be a great pairing. She's a skilled archer and a strong - willed character. Spider - Man and Artemis could have some great banter while on a mission, and their combined skills would make them a formidable duo.
Peter Parker (Spider - Man) and Captain America are also quite popular. You can see stories where Captain America takes Spider - Man under his wing, teaching him about heroism and leadership. It's an interesting dynamic as they come from different generations of heroes.
Daredevil could also be an interesting pairing. Both are street - level heroes with enhanced senses in a way. Assassin Spider - Man's acrobatic and stealth skills combined with Daredevil's martial arts and heightened senses would make for an exciting story. They could work together to clean up the seedy parts of the city.
Black Widow is a great character to pair with Hawkeye in fanfiction. Their history together in the comics and movies makes for an interesting dynamic. They can have a lot of action - packed scenes and also some emotional moments as they understand each other well. Another good pairing could be with Thor. Imagine Hawkeye's arrows and Thor's lightning working together in combat. It would be an epic combination.
Thor is an obvious choice. Their complex brotherly relationship offers a lot of material for fanfiction. They can have intense emotional scenes, from arguments to reconciliations. For example, in a story where Loki is on the verge of doing something really bad, Thor's attempts to stop him can be very engaging.
Definitely Captain America. Their old - fashioned values and combat prowess make for an interesting dynamic. They can lead the team together in a fanfiction, with Wolverine's wild side balanced by Cap's discipline.
