Definitely Iron Man. He could provide some high - tech support or be the one who sets up the initial meeting between Ant Man and Spiderman. His sarcastic remarks would also add some humor to the story.
Black Widow would be a great addition. She has the combat skills and the intelligence to help the two heroes in their mission. Maybe she's the one who discovers the villain's plan and calls in Ant Man and Spiderman to help.
Well, in a spiderman pokemon fanfic, Venom could be an interesting character to include. But instead of the traditional Venom, it could be a Venom - like Pokemon. And Spider - Man has to deal with this new threat. Also, Eevee could be in the story. Eevee has the potential to evolve into many different forms, and it could be a sidekick for Spider - Man. It could evolve in different ways depending on the challenges they face in the story, adding an element of growth and change.
One great Spiderman and Ant - Man fanfiction is 'The Team - Up of the Tiny and the Agile'. It has an exciting plot where they work together to stop a new villain in New York. The character interactions are really well - written, making it a fun read.
One idea could be a story where Ant Man and Spiderman team up to stop a new villain who has the ability to shrink and control insects on a large scale. They'd have to combine their unique skills, with Spiderman using his webs to swing around and Ant Man shrinking to get into small places the villain might be hiding.
One great 'Ant Man Fanfic' is 'The Adventures of Ant Man in the Quantum Realm'. It really dives deep into the unique world of the Quantum Realm that we saw in the movies. It has exciting action scenes where Ant Man uses his shrinking and growing abilities in creative ways to overcome villains.
Definitely Mary Jane. She could be in a dangerous situation that forces Spider - Man and Venom to work together. Her relationship with Spider - Man adds an emotional depth to the story.
The Green Goblin is a classic choice. His maniacal nature and his flying glider make for some exciting action scenes. Mary Jane could also be included. Her relationship with Spider - Man is an important part of the Spider - Man lore. And don't forget about Aunt May. She can add some heartwarming and sometimes comical family - related moments to the fanfic.
Obviously Naruto himself should be included as the main character in a Naruto one - man - team fanfic. Besides him, Kakashi could be a great addition as a sort of mentor figure who gives Naruto advice from time to time even though he's on his own. Another good character could be Jiraiya. He has a lot of knowledge and experience that Naruto could draw from in his solo adventures.
Hawkeye would be a great addition. He could provide long - range support during their adventures. His archery skills combined with Ant - Man's ability to get into tight spots and Captain America's leadership and combat skills would make for an exciting team dynamic.
Sonic himself is a must - include. His speed and adventurous spirit drive the story forward. Tails is also great as he can provide technical support and is Sonic's loyal friend. And Dr. Eggman, as the main antagonist, always adds conflict and excitement to the story.
Vegeta is a great choice. His rivalry with Goku adds a lot of drama and action to a fanfic. Also, Piccolo, as he has a long history with Goku and has been both an enemy and a friend. Another good character could be Gohan, Goku's son, as it can explore their father - son relationship further in the fanfic.
