Well, for 'Ben 10 Dragon Ball Z fanfiction', a cool concept could be that Ben gets caught in a time - space rift that sends him to the Dragon Ball Z universe right when a new and powerful enemy is emerging. Ben has to quickly figure out how to use his Omnitrix in this new world while also trying to get back home. And perhaps some of the Dragon Ball characters are intrigued by the Omnitrix and want to study it, leading to some funny and interesting interactions.
For example, Ben could use the XLR8 form and combine it with Goku's Instant Transmission. He could zip around at super - speed and then suddenly teleport to a new location, catching enemies off - guard. Or Heatblast's fire powers could be combined with Vegeta's Galick Gun, creating a super - powerful blast of fire - energy.
One interesting crossover could be Ben Tennyson using his Omnitrix to transform into an alien with powers similar to a Saiyan. For example, he could transform into an alien that can increase its power level like a Super Saiyan. Another could be the characters from Dragon Ball Super being intrigued by Ben's ability to change forms so quickly and effortlessly.
Well, a great aspect of crossovers in their fanfiction could be the battles. Imagine Goku from Dragon Ball Z facing off against Vilgax from Ben 10. Goku's martial arts skills and ki blasts against Vilgax's brute strength and advanced weaponry. And what if Ben, in his alien forms, had to team up with Goku to fight a common enemy? That would make for an exciting story.
If it's part of a story, it could imply that she's open to trying new things for her well - being. Ben wa balls can also be related to certain relaxation techniques, so perhaps it was part of her relaxation routine and it shows she values self - care.
It's really hard to say. Ben at his strongest has access to some incredibly powerful alien forms. But Goku at his strongest can literally destroy universes. However, if Ben could transform into an alien with reality - warping powers, he might have a chance. But Goku's speed and combat experience are also very high. So it could go either way depending on the situation.
I'm not sure what specific 'ben wa ball story' you're referring to. It could be something very personal to your wife's experience. Maybe you could provide more details to clarify.
It's hard to say, but Goku would be a top contender. His ability to constantly power up and reach new levels of strength like Super Saiyan God and Ultra Instinct is insane. But Ben in his Alien X form from the Omnitrix also has near - omnipotent powers. So it could really go either way depending on how the fanfiction writer sets up the battle conditions.
Ben 110 can be developed by giving him new challenges related to the Highbreed. For example, he could face a Highbreed villain who has a power that nullifies Ben's alien forms. This would force him to rely on his human intelligence and resourcefulness. He could also develop his character by learning about the Highbreed's language and communication methods, which would show his adaptability.
