The Insane Scientist

Chapter One

Summary: What if Mayuri Kurotsuchi went with the others that night that Aizen preformed his sick experiments and was killed? After a hundred and fifteen years later (?) Mayuri was reborn as Jessica Potter. With his or her past memories, Jessica began experimenting on herself to improve her body. Also later on people's pets at Hogwarts. Disclaimer: I own nothing. I wished that I did, but sadly I don't.

It was the summer after Jessica's fourth year and it could be simply said that everyone was nuts. Her twin brother, Evans Potter had witnessed the Dark Lord's return just last year. And now because of that, they had to stay at Hogwarts for the summer. Mayuri was caught between being pleased with the results of staying at Hogwarts or angry because of the change of plans that she as usual was not informed of until the last minute.

It was always like this for Mayuri to be ignored by the Potter family and her so called godfather, Sirius Black. She did not complain as she figured it could be worse with a family that always demanded her attention and time away from her experiments, like just recently, she replaced her ears with a weapon that she could use in case she was corned and did not have her wand with her. Everyone believes that Evans Potter was the Chosen One or from what she heard the Child of Prophecy. She had bugged the Great Hall where the meetings take place now in summer and she can watched them from her huge computer inside her trunk.

When Mayuri first got the trunk from her parents who seemed to be not too happy with her going to Hogwarts with Evans. She had to improve it and make it better, so with a bunch of runes, she was able to make it into multiple rooms like a mansion. Then she began building her computer that runs off of magic to store any data that she had collected. Just last year, she had finally created Nemu Kurotsuchi, her daughter, who turned out to be a great help to her whenever she was off in classes. She would never admitted even if it will save her soul from hell. But Nemu stays inside the trunk no matter what; Mayuri will not take the chance of her being discovered.

Mayuri Kurotsuchi also known as Jessica Potter was 5'5' and still growing. She had her long black hair tied back so it could not get in her way when she experiments and also to hide what she did to her ears, so no one could make a fuss over what she had done to them. She also painted her fingernails blue and on her right hand, she grew her fingernail on her middle finger, five inches. People and her family thought she was weird, but Mayuri never really cared about that at all. To her, they were experiments waiting for her to get to them. She knew that she could not do that as the Soul Society might find out about her and her projects. Mayuri had to wonder what ever happen with Aizen and his two kiddies that was with him that night. She personally would like to get them onto her table and dissect them and see what makes them tick.

"There you are, Jessica. I was looking everywhere for you," Lily said as she saw that her daughter came into the Great Hall for breakfast.

"No wonder you could not find me, I was taking a shower before coming down here. It's a normal thing to do in the morning, is it not?" Mayuri asked her, honesty her life would be a whole lot better if Lily Potter was not in it.

"Don't be rude to your mother, Jessica Potter," James snapped at his daughter.

"I was just simply answering her question. No need to snap at me, Potter," Mayuri sneered as she got up with a plate full of food and began walking out.

"Where are you going, Jessica? Can't you sit here with your family and spend some time with us?" Lily asked as she saw that her daughter was going to walk out again with a plate full of food.

Mayuri stopped and said, "I am going to do something worth my time. I don't really like it if I waste it. And besides, you don't need me; you got Evans to spend time with."

The others in the Great Hall just watched as Mayuri walked out of the hall. They all don't know what to make of her and they all knew that they did not know much about her. Jessica Potter has no friends and made no effort make any, although Luna Lovegood did sometimes hung out with her. She was never friendly or nice to anyone and everyone made an effort to keep out of her way. Only place that anyone may find her was in the library, pouring over books and making notes. She was the top student in every class. And she can make a seventh year cry like a five year. And another thing to note was that ever since she first started Hogwarts, pets like Mrs. Norris went missing, even Fluffy, Hagrid's three headed dog. Snape still believes to this day that Jessica Potter is responsible for their disappearances, but no one really wants to believe him.

"I just wish that I could get to know our daughter and spend some time with her. That's all," Lily begins to cry.

"I know, sweetie. Everything will be okay, she just needs some time to get use to us wanting her around," James said as he tries to comfort her as best as he could.

Snape even snorted and said, "I really doubt that will ever happen. I believe that Miss Potter made the choice to be anti-social on her own. You know, sometimes whenever I have her in my class, she gets this craze look in her eyes whenever she works on the potion that I assign them at that time. I think that she is beyond our help."

"What do you mean that she is beyond our help, Snape?" Sirius questioned him. Sirius was Jessica's godfather, but he was never that person to her. He always spent time with her younger twin, Evans when they were younger. Now after what happened last year, he seriously regretted his action and what they have done to Jessica.

"What Severus means is that Jessica Potter is an insane researcher and a mad scientist all rolled into one. I watched her myself on several occasions without her knowing it and just last year, she was able to create something that looks, acts, and has all of the functions of a human being. It's a pity that Jessica must keep her locked up in that trunk of her. But as I was saying, Jessica Potter is the type of person that is driven to gain knowledge, but unlike Tom Riddle who would use that knowledge to do evil things to other people, she just wants to know. But she would do anything to gain that knowledge," Headmaster Dumbledore explained to the others.

"We also forgot to mention to her that an old friend of mine is sending some people that can help up with defeating Tom," The Headmaster said.

"Nemu, has there been any more blasts of spiritual pressure in Japan lately?" Mayuri asked as she ate her share of the food that she brought with her while leaving the rest for Nemu.

"No, but I did find out something important," Nemu said.

"Well, what is it? Answer me, I don't have all day you know," Mayuri snapped at Nemu.

"Headmaster Dumbledore knows about me and that you created me." Nemu answered.

"WHAT! Show me, now!" Mayuri shouted as Nemu pressed in some keys on the computer keyboard.

Snape even snorted and said, "I really doubt that will ever happen. I believe that Miss Potter made the choice to be anti-social on her own. You know, sometimes whenever I have her in my class, she gets this craze look in her eyes whenever she works on the potion that I assign them at that time. I think that she is beyond our help."

"What do you mean that she is beyond our help, Snape?" Sirius questioned him. Sirius was Jessica's godfather, but he was never that person to her. He always spent time with her younger twin, Evans when they were younger. Now after what happened last year, he seriously regretted his action and what they have done to Jessica.

"What Severus means is that Jessica Potter is an insane researcher and a mad scientist all rolled into one.

But she would do anything to gain that knowledge," Headmaster Dumbledore explained to the others.

"We also forgot to mention to her that an old friend of mine is sending some people that can help up with defeating Tom," The Headmaster said.

"HOW DARE HE! Spying on me. I just can't believe I did not even notice that. Well, I will solve that just in case he did that again," Mayuri ranted to Nemu as she began thinking of ways to make sure that she could find the Headmaster no matter where he is.

Without turning around, Mayuri said to Nemu, "Since the Headmaster knows about you and told everyone about you, Nemu, for now on you will be accompanying me everywhere, unless I tell you other wise. Understand?"

"Yes, Mother," Nemu said to Mayuri before getting something that Mayuri needed.

I wonder who are those friends of the old coot who are coming. I hope that they won't get in my way, Mayuri thought to her self.

(Scene Break)

The Headmaster stopped in front of Jessica's trunk and called out, "Jessica, I would like for you to come to my office to talk about some things right now and please bring that young woman that you created with you. I will like to meet her. Oh, I hope that you like lemon drops."

The Headmaster only had to wait less than a minute before the trunk lid opened and out step Jessica and the young woman. Jessica had a look on her face that basically said that what he wants to talk about better be good or else someone is going to suffer. A lot.

"Good, please follow me," Headmaster Dumbledore told them.

(Scene Break)

"Now that we are all comfy. Is there anything that you two would like to drink or eat before we get started?" Dumbledore asked.

"No, just get to the point, you old coot!" Mayuri snapped at him. Mayuri was angry that someone had the nerve to pull her away from her project.

"Very well then," Headmaster Dumbledore said as he studied Mayuri carefully. "Miss Potter, what do you know of the Soul Society?"

Mayuri froze as she did not expect that question, anything but that question. Mayuri's mouth was wide opened and it seemed that her eyes would pop out of her head.

"I take it from your expression that is on your face that you do know what I'm talking about. Tell me, did you stumble on the information in a book or were you reincarnated with your memories intact?" Headmaster Dumbledore asked as he was now very curious about Jessica Potter. If she was reincarnated with all of her memories intact, it will explain a lot of things about her.

AN: I hope that you all like it. This story just popped into my head and refused to get out until I wrote it down. To make a few things clear, Mayuri was reborn as a girl, will not be abusive towards Nemu, and a little less crazy than before. The next chapter will be the confession of Mayuri and she will tell Dumbledore about her past life. Oh, before I forget Mayuri is also known as Jessica Potter. Please review and tell me what you all think of it. Have a nice day, everyone.
