Who would be the most interesting character combination in a 'Ben 10 Avengers fanfic'?

I think Ben's Heatblast and Thor would be an interesting combination. Heatblast can generate intense heat and fire, while Thor has his lightning powers. They could create some really powerful elemental attacks together.

Ben's XLR8 and Beast Boy would be a great combination. XLR8's super - speed could be used in some really creative ways when paired with Beast Boy's ability to transform into different animals. For example, Beast Boy could transform into a bird and XLR8 could carry him at high speed, allowing them to scout out areas quickly or surprise enemies. Also, their personalities are both kind of fun - loving and energetic, so they would get along well and have a lot of banter back and forth as they fight together against the bad guys.

A really cool character combination would be Hawk Moth and Vilgax. Hawk Moth's ability to akumatize people and Vilgax's thirst for power and his vast array of weapons and skills would be a terrifying combination. They could team up to take over both the Miraculous and Ben 10 universes. On the other hand, Tikki and Heatblast could also be an interesting pair. Tikki's positive energy and Heatblast's ability to generate and control fire could lead to some unique interactions. Maybe Tikki could help Heatblast control his power better or they could use their combined powers to defeat a powerful enemy.

Erza and Captain America would be an amazing combination. Erza is a strong and disciplined warrior in Fairy Tail, and Captain America is the symbol of justice and leadership in the Avengers. Erza's various armors and combat skills combined with Captain America's shield and strategic thinking would make them a formidable team. They could lead the combined forces of Fairy Tail and the Avengers in battles against powerful foes, and also inspire the other characters with their unwavering determination.

Ben as Diamondhead and Zoro would be really interesting. Diamondhead's crystal - like body could provide a great defense against attacks, and Zoro's swordsmanship could be enhanced with Diamondhead's sharp edges. They could team up in battles and create some unique combat strategies.

Definitely Ben Tennyson and Iron Man. Tony Stark's high - tech gadgets and intelligence would pair well with Ben's Omnitrix. They could exchange knowledge about technology and come up with some really cool inventions together. Also, Iron Man could probably upgrade the Omnitrix in some way.

Ben and Star would be the most interesting combination. Ben with his ability to transform into different aliens and Star with her magic wand. They could combine their powers in unique ways. For example, Ben could transform into an alien that can fly and Star could use her magic to enhance its speed.

A very powerful combination could be Ben as Alien X paired with Doctor Strange. Alien X has near - omnipotent powers, and when combined with Doctor Strange's magic, they could be an unstoppable force. They could manipulate time, space, and reality in ways that no single villain could counter.

I think Jack - Jack would be really interesting. His unpredictable and ever - changing powers could bring a lot of chaos and fun to the story. He could be the wildcard that the Avengers don't quite know how to handle at first. Maybe he accidentally turns into something that causes a big problem, like a giant monster, but then uses his powers in a creative way to help solve it later.

Definitely Goku and Luffy. Goku is all about pure power and the pursuit of stronger opponents, while Luffy has his own brand of determination and his stretchy powers. Their combined energy would be so much fun to read about.
