Ben 10/Highschool DxD crossover challenge
This is my challenge to those of you interested in making your own Ben 10/Highschool DxD crossover. There are some ground rules offered for me by jfhakala, who requested this in the first place.
1. Ben travels to the DxD Verse by some means (either Paradox or a trans-dimensional device sends him there but it is a one-way ticket, at least initially)
2. Ben gets the DxD Harem including a FemIssei (the FemIssei can be just a perverted as the original in order to create a sense of competition amongst the Harem, and can have another name at the authors discretion)
3. As FemIssei masters her Boosted Gear she gains a more voluptuous figure that she uses to try and seduce Ben with(this also gives her a reason to train more) for the aforementioned competition.
4. Ben is to remain Human in his base state and not be reincarnated into a devil or angel under any circumstance (the angel part is if the author writes the story that far into the canon series), the only way Ben is to become any one (or all of them) of the races of the Three Factions is via the power of the Omnitrix/Ultimatrix.
5. Ben is to train in magic and via that training he himself becomes marginally stronger himself, is capable of controlling the Omnitrix/Ultimatrix through mental focus, and gains a much longer life (along the lines of either a devils life span or a dragons depending on the author), with his alien/inhuman forms becoming significantly more powerful either the inclusion of skills Ben knew they had but couldn't master or with their innate ones being amplified.
But apart from that, you can do whatever you want. I hope that's enough to live by.
Enjoy, and have fun writing.
edit: Just also mentioning there's no point sending me messages about ideas you have. I've passed this on to all you guys. If you've got good ideas, then start writing. That's how I work.
