Xander and Methos would also be an interesting combination. Methos is one of the oldest and most cunning Highlanders. Xander's more impulsive nature could contrast well with Methos' calculated ways, and they could get into all sorts of adventures together.
Another good pairing could be Xander and Amanda. Amanda is a female Highlander with a bit of a roguish streak. Xander might be attracted to her charm, and they could team up to pull off some daring heists or fight against common enemies in their crossover adventures.
Xander and Duncan MacLeod could be a great pairing. Duncan has centuries of experience as a Highlander, and Xander has his own unique experiences dealing with vampires and demons. They could learn a lot from each other.
Sam Carter and Methos would be a fascinating combination. Sam's scientific genius could be intrigued by Methos' ancient knowledge and long - lived existence. Methos might also be able to offer some unique perspectives on the technology Sam deals with in the Stargate program, and together they could come up with innovative solutions to problems.
One idea could be that Xander discovers he has the immortality of a Highlander. He then has to navigate his newfound ability while still dealing with the usual supernatural threats in his world. Maybe he teams up with a Highlander character to learn more about his new condition.
Amu could be paired with Naruto from Naruto. Amu's shy yet strong - willed nature combined with Naruto's determination would make for an interesting dynamic. They could learn from each other's ways of facing challenges, with Amu teaching Naruto about the importance of inner self - discovery and Naruto showing Amu how to be more bold in the face of danger.
Ruby and Joker could be a great pairing. Ruby's enthusiasm and determination combined with Joker's cool - headed leadership skills would make for an interesting dynamic. They could learn from each other's combat styles and ways of thinking.
Uno and a flamboyant character from a magical anime. Uno's charm and confidence could either clash or blend really well with the over - the - top personality of the magical character. They could exchange fashion tips or compete in a popularity contest within the crossover world.
Kakyoin and Luffy from One Piece would be an unexpected but fun pairing. Kakyoin's calm and strategic mind would be an interesting contrast to Luffy's carefree and impulsive nature. They could work together in a battle, with Kakyoin using his Hierophant Green to create distractions or attack from a distance while Luffy charges in head - first, using his Gum - Gum powers to take on enemies directly.
Lavi and Edward Elric. Lavi is always curious and loves to explore different things, which is similar to Edward's thirst for knowledge. They could bond over their shared love of books (since Lavi is a Bookman) and also their quests for the truth. Edward could help Lavi understand more about alchemy, while Lavi could introduce Edward to the world of Innocence and exorcism.
Koneko and a god of nature could form a unique pairing. Koneko's connection to her cat - like instincts might be related to the god of nature's domain. The god could help Koneko further explore and enhance her powers, while Koneko could show the god a different perspective on the world of the supernatural that exists in the High School DxD universe.
A good pairing could be Yuma and Sonic from the Sonic the Hedgehog series. Yuma's determination and Sonic's speed could make for an interesting combination. They could race through levels while also having to duel against enemies. Another pairing could be Astral and Tails. Tails' intelligence could help Astral understand new technologies in a crossover world, and they could work together to solve problems. Also, Shark and Knuckles would be a great pair. Their tough - guy attitudes would match well, and they could have some epic battles together while also dueling when needed.
A great pairing in a Dragon Ball crossover fanfiction could be Trunks and the Flash. Trunks' time - traveling abilities and the Flash's super - speed would be an exciting combination. They could race through time and space together. Another interesting pairing would be Bulma and Iron Man. Bulma's scientific genius and Iron Man's technological prowess would lead to some amazing inventions and adventures.
