Deadpool and Wolverine are a great pair. Wolverine's serious and no - nonsense attitude contrasts perfectly with Deadpool's zany and irreverent personality. They could have some epic battles where Deadpool's constant chatter drives Wolverine crazy, but also some moments where they realize they're not so different. Another good pair would be Deadpool and Rogue. Rogue's power - absorption ability could lead to some interesting situations when she tries to touch Deadpool, and his unpredictable nature would keep her on her toes.
Cable would be a great character to pair with Deadpool. Their dynamic in the comics is really interesting, with Cable being the more serious and brooding type compared to Deadpool's zaniness. In a game fanfiction, they could be on a mission together and Deadpool could be constantly annoying Cable with his jokes and antics.
Wonder Woman is another great choice. Her strong moral code and powerful abilities would be an interesting counterpoint to Deadpool. He might be in awe of her at first, and then start trying to crack jokes and get on her nerves, but they could also form an unlikely friendship as they fight together against a common enemy.
Naruto could be a great character to pair with Menma. Their personalities could create an interesting dynamic. Naruto's determination and Menma's more gentle nature could complement each other well in a story about friendship or even a budding romance.
A rogue could be a great character to pair with an artificer in fanfic. The rogue's stealth skills combined with the artificer's gadgets can lead to some really interesting heist - like scenarios. For example, the artificer could create a device that disables security systems while the rogue sneaks in to steal a valuable item.
Tanjiro would be a great character to pair with rengoku. Their different personalities could create an interesting interaction. Tanjiro's kind - hearted nature and rengoku's fiery determination could lead to some great storylines.
Hawks is a great character to pair with Dabi in fanfic. Their relationship in the original story is complex and full of tension, which can be explored further in fan - made stories. There's also Shigaraki. Since they are both important members of the League of Villains, there's a lot of potential for interesting dynamics between them in fanfics.
Yoshi would be an excellent character to pair with Bowuigi. Yoshi's friendly and helpful nature can contrast or complement Bowuigi's personalities. Donkey Kong is another good choice. His brute strength can be a great counterpoint to Bowuigi's more strategic thinking. And Toad could be added for his loyalty and sometimes comical nature.
Goku could be a great character to pair with Caulifla. His powerful Saiyan abilities and his experience in different battles could create interesting interactions with Caulifla in her futanari form. They could train together or face off against a common enemy.
Another good character to pair with Harry Salem is a young and inexperienced wizard. Harry could be a mentor figure to them, and at the same time, the young wizard's fresh view of things could inspire Harry to see things in a new light. This dynamic can create a lot of character growth and interesting interactions in the fanfic.
His sister, Mirabel, would be a great pairing. They could have adventures together, with Mirabel's determination and Camilo's shape - shifting ability. They might team up to find out more about the secrets of the Encanto or deal with a problem that the family is facing.
