As I have said in my announcement, I challenge anyone here on Wattpad, as well as on FanFiction.Net later on, to make a Ben 10 x My Hero Academia crossover.

Reason was said in my earlier post as well, there aren't many stories where Ben is included as a main character, mostly with either a reader insert gaining the Omnitrix, an OC, or Izuku getting it. I'm not against it but a guy can only handle so much, and not to mention it's starting to feel a little stagnant at this point.

Any-who, these are the guidelines for the stories, as in plural, there are multiple story types for fic writers to try out. Also there isn't a limit for how many people can accept these challenges, multiple people can get in on this if they want.

Guidelines
-Ben Tennyson has to be included on the story, yes other characters like Gwen, Max, Kevin and Rook can be included to but Ben has to be one of the main characters.

-The Ben 10 side of the series must be derived from the prime universe, not Ben 23, not Gwen 10, not Mad Ben, not Bad Ben, not Emo Ben, not no watch Ben, maybe any of the three shown Ben 10,000s, but only Ben Prime. Timeline Ranges can be from Alien Force to Omniverse, you can use the original series but do not have 10 year old Ben in the present time. Do not use the reboot but you're allowed to use reboot transformations like Gax, ShockRock and Slapback.

-Ben has to have the Omnitrix, it's the staple of the series and I prefer having Midoriya warm his powers from All Might. Maybe have Ben be another mentor to Izuku, helping him control One for All as he has experience using various similar abilities.

-no having Ben bequeathing the Omnitrix to other characters, don't complain I know some people were gonna try and use that as a loophole.

- no reader inserts, at all!

optional
-this guideline is optional but I enjoy it, have Ben later gain his own quirk. If you are having trouble with working that out, try using the Gene-Splicing route, like Ben somehow got into an accident during one adventure with his new friends from the MHA universe and ended up gaining a quirk of his own by some random genetic replication thing. Also try and have it coincide with his Omnitrix as just having his ability limited by like an element is being biased. There's also the Multiversal travel acclimation rule in fiction, by this I mean that when characters travel from world to world their bodies can adapt to the new universe's laws of physics, properties and the adaptations of local residents of the same species. Like for example saying that if a character travels to a universe with humans having magic they eventually gain the ability to use magic.

-I know I'm gonna regret saying this. Lemons are at the very least optional. I was convinced to at least put this in after a friend of mine reminded me of how much stories like this can still be good despite its... rather adult background... and by friend I mean Aphro.

Story Types

-Classic Ben 10 Isekai: like some well known stories like Ultimate Fairy, Ben 10 Unlimited, Avenging 10, as well as many of my stories and the cancelled RWBBYverse; clash of heroes, still a great Fic in my opinion. Having Ben transported from his world to the MHA universe. A bit used but if it isn't broke there isn't any need to fix it.

-Reverse Isekai; an inverted version of what normally happens, similar to the Ben 10 x Blazblue Galactic Shift Extend story on FanFiction.Net, this one has the characters of My Hero Academia being transported to Ben's world. While this is a flip version, it's rarely seen and admittedly very good.

-Universe Hybrid; basically having Both universe combined, Ben lives in a world of quirks and has one of his own but it coincides with his watch. Much like Misaka_Omnitrix new book, but instead Ben has a quirk that dormant was either dormant or awoken after he gained the Omnitrix.

-Total Isekai; having characters from both universes thrown into a completely different one, nothing similar to either world. A garden variety earth like ours, and the being there influences either prosperity or chaos, just to spice things up.

Pairings between Characters are up to you, though I am personally against Bakugou x Uraraka... no offense but I don't like the exploding jerk face and Ochako deserves better than him.

Well here it is, while I know not everyone will be interested at least take a consideration. And please recommend this challenge to others you think will enjoy writing this, hope to see some results. Remember these challenges can be accepted my more than just one person. Also if you write in a different language, please have multiple books open in other languages including English so we could all enjoy them.
