Ash and Four Arms would be a great pair. Four Arms is all about brute strength, and Ash has his knowledge of Pokemon and his own battle skills. They could work together in battles against powerful foes. Maybe Ash could learn some new fighting techniques from Four Arms, and Four Arms could learn about the subtleties of Pokemon battles. It would be a clash of two different but equally cool fighting styles.
Gwen from Ben 10 and Eevee could be an interesting combination. Gwen has her magic powers which could interact in interesting ways with Eevee's ability to evolve into different forms. They could explore new places together, with Eevee being curious and Gwen using her intelligence and magic to protect them. Also, Eevee could be like a little sidekick to Gwen, and they could have some really cute moments while also having adventures.
Another interesting pairing could be Ben and Captain America. Cap's leadership and moral compass could influence Ben, while Ben's diverse powers could be a great asset to Cap in battle. They could be in a situation where they have to fight against a mind - controlled army, and Ben's aliens like Big Chill could freeze the enemies in place while Cap gives strategic commands.
Sonic and Pikachu would be a really interesting pair. Sonic's high - speed and adventurous nature combined with Pikachu's electric powers and cute but brave personality could lead to some really fun and action - packed scenes. They could race each other and then work together to face challenges.
I think Knuckles from Sonic and Lucario from Pokemon would make a great pair. Knuckles is strong and has a connection to ancient powers, similar to Lucario which has a strong sense of aura. They could bond over their shared connection to something deeper. In a fanfiction, they could team up to protect an ancient temple that has significance in both the Sonic and Pokemon worlds. Lucario could use its aura - sensing abilities to detect threats, while Knuckles could use his strength to fight off any physical attackers.
Pairing Ben with Natsu would be really interesting. Natsu is all about fire and brute strength, while Ben has a wide range of alien powers. They could learn a lot from each other. Ben could show Natsu some high - tech gadgets and Natsu could introduce Ben to the world of magic. Their different personalities, Natsu's hot - headedness and Ben's more laid - back nature, would also create great chemistry.
Ben and Twilight Sparkle would be really interesting. Ben has his street - smart and action - oriented nature, while Twilight is all about knowledge and magic. Their interactions could be really fun, like Ben showing Twilight some of his alien tech and Twilight trying to understand it with her magical knowledge.
Ron Weasley and Four Arms from Ben 10. Ron is known for his loyalty and his skills in wizard chess. Four Arms is a strong and powerful alien. Their personalities are quite different. Ron might be a bit intimidated by Four Arms at first, but as they get to know each other, they could form an unlikely but strong team. Four Arms could help Ron in physical battles, and Ron could use his wizarding skills to protect Four Arms from magic - based attacks.
Kanan Jarrus and Ben Tennyson would make an interesting pair. Kanan is a Jedi Knight, so he has a lot of skills and knowledge about the Force and combat. Ben, with his Omnitrix, has a wide range of abilities. Kanan could help Ben understand the more spiritual side of the Star Wars universe, while Ben could use his alien forms to assist Kanan in battles. For example, if they were facing a large group of stormtroopers, Ben could transform into Cannonbolt and roll into the group, while Kanan used his lightsaber and the Force to take out the rest.
Definitely Ben and Ash. Ben with his Omnitrix and ability to transform into different aliens brings a whole new dimension of power and adventure. Ash, on the other hand, has his experience and deep connection with Pokemon. Their interactions would be fascinating. For instance, Ben might be amazed at how Ash can communicate with his Pokemon without any high - tech device, and Ash could be in awe of Ben's alien forms and their powers.
Naruto and Hermione would be an interesting pair. Hermione's intelligence combined with Naruto's determination could lead to some great adventures. They could study magic and ninjutsu together, with Hermione helping Naruto understand the more complex magical theories, and Naruto showing Hermione how to be more physically tough.
Naruto and Ruby themselves would be an obvious and interesting pair. Naruto's determination and never - give - up attitude combined with Ruby's courage and combat skills could make for some great interactions and storylines.
