Hello this is D00m0fDark91 and this is my first fanfic so please go easy on me. Now this is a crossover between Sonic the Hedgehog and Highschool DxD with some elements from the Dragonball series, mostly when it comes to the super forms. The story will take place in the HSDxD universe with Shadow the Hedgehog but he will be human and not quite his usual self. What I mean by that is he'll only be serious in fights and when he needs to be, but other than that he will have a small personality change to where he's not such a loner. I'm having him replace Issei in Rias's peerage and he'll have have a different sacred gear. I'm still working out the details of the sacred gear but it will give him the powers of both the Boosted Gear and Divine Dividing. And he will be known as the Black Dragon Emperor.

He will still be created but he will have a mother and a normal childhood. If you want to know what he looks like use the image art by Selene-Galadriel on deviant art but without the ears and tail. And yes for those who are wondering this will be a harem fic. I may add lemons but I'm still not sure. If you have suggestions please let me know, anyway it's time to start the story.

Chapter 1

Origins

Space Colony Ark

In a lab stood a woman in her mid twenties looking into a incubator tube. In the tube a small baby floated in the water with a mask around his face that helped him breathe. He had black hair with red highlights and his skin was tanned. The woman placed her had on the glass as she heard footsteps from behind her. She looked back and saw a man in his late fifties with a long mustache, dark blue glasses over his eyes, wearing a white lab coat, black pants, and black shoes.

" Good evening Dr. Robotnik" the woman said.

"Hello Sora, how are you today?" he asked.

The woman now known as Sora merely smiled and looked at the child and said " I'm doing fine but I can't wait to meet my son."

Dr. Robotnik also smiled but it was slightly sad because he knew the real reason why that child was created in the first place and said " Sora, you do know the rea-"

" I know Doctor, you don't have to remind me!" Sora interrupted as she looked down sadly.

The two stood in silence for what seemed like hours when Sora took a trembling breath and said "I'm sorry."

"It's okay I know that this is hard for you since you couldn't have a child by normal means." Dr. Robotnik said sorrowfully, as he knew due to her over using the power of the Chaos Emeralds it robbed her of the ability to reproduce.

They both stood in front of the tube in silence for a few minutes until the doctor said "You know, I could pull some strings to see if you can take the boy down to earth and raise him as you see fit."

Sora quickly looked at him with a shocked look on her face and just stood there for a second. The doctor saw her look and said " But it's only until he turns eighteen because you know as well as I do that earth needs a protector and Shadow is the only one with the power to do so."

Sora just stood there as tears welled up in her eyes and said "That is more than I could have hoped for and I promise that I will teach him how to use his powers so he is ready to assume that responsibility for when that time comes."

"Than I will make the arrangements for your new life with your son and don't worry the military will pay for everything ." he said as he turned around to go do just that.

"Thank you doctor." Sora said as he walked away and he just waved his hand. She turned around to look at the small child with a happy smile as she couldn't believe that she was actually going to raise him like she wanted.

Well that's a rap, I'll try to make the chapters longer in the future but I just wanted to give you guys a little idea of how Shadow came to live a somewhat normal childhood. Anyway I had a few ideas and I would like your opinions on them. First I was thinking of adding a few characters from A Testament of a New Devil Sister, just the girls and maybe the hero faction but let me know if I should add the latter because I want to add the girls. Second about Issei I decided to put him in Sona's peerage because I think she is the only person that can straighten him out because of the way she disciplines Saji lol. Thirdly I was thinking if I should have Xenovia already be apart of Rias's peerage before Shadow, I will go into greater detail about how that happened but the basic idea is that she overheard some priests talking about God being dead and they excommunicated her for learning that secret.

Fourth I will be giving Shadow that sword he wielded in Black Knight but it won't be till later. Fifth I will be doing time skips but just the boring bits and just until I'm past the Riser Phenex ark.

Harem: Rias, Akeno, Koneko, Xenovia, Asia, Sona, Mio, Yuuki, and Amy Rose.

If you have any suggestions of who I should add let me know.
