One idea could be to have Ben Tennyson end up in the Young Justice universe by accident. Maybe his Omnitrix malfunctions during a fight and transports him there. He could then team up with the Young Justice heroes to fight a common enemy like the Light or some new villain that's a threat to both universes.
Well, it could be about a crossover in the Ben 10 universe that involves neglected or overlooked characters or storylines. Maybe it's a fan's attempt to give more spotlight to those parts that the official shows or comics didn't fully explore.
In a Ben 10 and Naruto fanfic, their powers would be a great combination. Ben has the ability to transform into various alien forms, each with unique powers. Naruto has his chakra and his powerful jutsu. They could learn from each other. For example, Ben could teach Naruto about some of the alien technologies, while Naruto could teach Ben about chakra control and the ninja way.
There's a Ben 10 and Generator Rex crossover fanfiction that's quite good. In it, the two heroes with their different kinds of powers team up to face a common threat. It delves into how their powers could complement each other. For example, Rex's nanites and Ben's alien forms could be used in tandem to overcome obstacles that neither could face alone. This fanfiction also focuses on the friendship that could develop between the two main characters.
It's hard to say. Ainz Ooal Gown has a vast array of powerful magic spells at his disposal. However, Ben when he transforms into Alien X could be extremely powerful as well. Alien X has reality - warping abilities. But Ainz has his intelligence and strategic thinking. So it could really go either way depending on the situation.
Well, it could be really exciting. Ben 10 has all those cool alien forms he can transform into. Imagine him facing off against a Xenomorph. His Heatblast form might be able to use its firepower to keep the Xenomorph at bay. And his Four Arms form could have a physical fight with it. It would be a battle of different kinds of alien powers.
One idea could be that Ben Tennyson, while on a mission in another dimension, accidentally lands in the X - Men's universe. His Omnitrix starts acting strangely due to the different energy signatures there. The X - Men initially see him as a threat but then realize he could be an ally in fighting a common enemy, like a powerful mutant - alien hybrid that is causing chaos. Ben could transform into some of his alien forms to help the X - Men in battles, and there could be interesting interactions between the different characters, like Gwen and Rogue comparing their powers.
One possibility could be that Ben Grimm, as The Thing, brings his unique strength and loyalty to the Avengers. His rocky exterior could be a great asset in battles, like providing cover for his teammates. He might also have some interesting interactions with the other Avengers, especially those with a sense of humor like Tony Stark. They could make some witty remarks about his appearance while also respecting his power.
In a Ben 10 Avengers crossover fanfiction, the story might involve Ben and the Avengers sharing their technology and knowledge. Maybe Iron Man could upgrade some of Ben's alien tech, while Ben could show the Avengers some unique alien abilities they've never seen before. It could also lead to some interesting character dynamics, like Spider - Man and Ben comparing their powers and how they use them to protect the city.
One unique element is the combination of two very different power systems. Ben 10 has his alien - based powers like Heatblast's fire - related abilities and Four Arms' super strength, while MLP has magic. When these two collide in fanfiction, it creates interesting scenarios. For example, how would a magic spell interact with an alien transformation? Another unique aspect is the cultural clash. Ben comes from a more action - oriented, technology - based world, and the ponies live in a more harmonious, magic - based society. This contrast often leads to humorous and thought - provoking situations in the fanfiction.
