Meta Knight being a badass as usual and Kirby achieved his first form: Fire Kirby! I can see our adorable puffball performing Combination Attacks with some of Ben's forms. And as for transformations like Cook Kirby, Artist Kirby or Cleaning Kirby, an interesting approach is for one to pop up in a very serious battle and the realization to both sides is that you should never underestimate Kirby at all. Cook Kirby is the goofy equivalent to Crash Kirby. Good luck with your story!

OH MY GOD YES! This is just absolutely amazing! Your mixing the worlds of Kirby and Ben 10 so well! I can't wait for the next chapter!

Time for some logic.

Nice.

Do more of this or i will kick your ass this is torture

Good one.

This is the first Kirby x Ben 10 fanfic I've ever seen and HOLY CRAP I AM SO EXCITED FOR THIS! I cant wait to see hat comes next

Two words I have to say. Holy Shit. This definitely has quite promising premise especially when you take into consideration Kirby as a whole, both games and the anime. Sure it looks like a very cute game with cute characters but deep down it can get REALLY dark. The flavor text for certain boss battles steamrolls that point into the ground. Ben 10 also has its dark moments despite most of the time being light-hearted. Second, Alien Force really hit home for not only action, comedy but also character development. Julie and Ben were a perfect pairing then Ultimate Alien smacks it with a hammer and Omniverse destroys any chance than just the whole good premise built up by Alien Force.

I do suggest that you switch up the Kirby and Ben 10 bosses at certain points as you progress the chapters. Make a point that there's still another threat than just the main one. And I agree about the RWBY crossover becoming way too much. Kirby was a good idea but it slowly became bland and repetitive.

Anyways, good luck on this story!

Kirby is certainly one of a kind.

Ok, so far so good
