Gumball and Finn from 'Adventure Time' make for an interesting pairing. Finn's heroic and adventurous nature contrasts with Gumball's more comical and sometimes self - centered personality. Another cool pairing is Gumball and Sonic. The speed of Sonic combined with Gumball's unique abilities would lead to some exciting adventures. Also, Gumball and Steven from 'Steven Universe' could be really interesting as they both have a strong sense of family and adventure, but in very different ways.
Well, I think Gumball and Batman would be a fascinating pairing in crossover fanfiction. Batman's dark and brooding nature against Gumball's light - hearted and goofy self would create a great dynamic. Then there's Gumball and Ash from 'Pokémon'. Ash's journey to become a Pokémon master and Gumball's daily life in Elmore would be an odd but interesting mix. And Gumball and Dipper from 'Gravity Falls' could team up to solve mysteries that span both their worlds, with Dipper's love for the supernatural and Gumball's ability to get into all sorts of trouble.
One of the most interesting pairings is Gumball and Link from 'The Legend of Zelda'. Link's quest - filled life and his skills with a sword could be a great contrast to Gumball's normal - yet - abnormal life in Elmore. Another interesting pair is Gumball and Lilo from 'Lilo & Stitch'. Lilo's connection with Stitch and her unique family situation combined with Gumball's family in Elmore could lead to some heartwarming and funny stories. Also, Gumball and Jake from 'Adventure Time' would be a great duo. Jake's shape - shifting abilities and Gumball's resourcefulness could result in some really wild and unpredictable adventures.
Gumball and Jotaro would be really interesting. Gumball's energetic and goofy nature would contrast greatly with Jotaro's cool and stoic demeanor. They could learn a lot from each other, like Gumball could teach Jotaro to have a bit more fun, while Jotaro could show Gumball how to be more serious when the situation demands it.
Penny is often a popular character in fanfictions too. Her unique form and her relationship with Gumball give a lot of room for interesting storylines. Writers might explore how their relationship develops over time, or create scenarios where Penny has to use her special abilities to save the day.
Darwin is another popular character. His loyalty to Gumball and his own growth throughout the series are often explored in fanfictions. There are stories where he has to be the brave one and save Gumball from a difficult situation, which shows his importance in the fanfiction world.
Yukari (from Persona 3) and Chie (from Persona 4). Yukari is very outspoken and has a bit of a sarcastic side, while Chie is energetic and a bit of a tomboy. Their different personalities could lead to some really fun and comical interactions, especially when they're facing Shadows together or just hanging out in the school setting.
Thomas and Twilight Sparkle. Thomas is a simple, hard - working engine, while Twilight is a studious and powerful unicorn. Their different natures could lead to some really interesting interactions. For example, Thomas could teach Twilight about the value of physical work and Twilight could introduce Thomas to the magic of knowledge.
There's an OC named Starlight who is quite popular. She has the ability to control stars and often uses her powers to help Gumball and his friends out of tricky situations. Her design is also really cool, with a star - themed dress and glowing hair.
One idea could be a crossover with 'Adventure Time'. Gumball and Finn could go on a wild adventure together, facing challenges in a mixed - up world of both shows. Maybe they have to find a magical item that got lost between their universes.
Gumball is often a very popular character in fanfics. Since he is the main character of the show, a lot of fanfics revolve around his adventures. Darwin is also quite popular as his sidekick. Their dynamic together is something that many fanfic writers like to play with.
Definitely the Flash and Iron Man. Tony Stark's high - tech gadgets and intelligence combined with the Flash's super - speed would make for some really cool scenes. They could work together on building some sort of super - fast vehicle or weapon. Another interesting pairing would be the Flash and Captain America. Steve Rogers' leadership and combat skills along with the Flash's speed could be a great combination for taking on enemies. The Flash could quickly get Steve into strategic positions during battles.
