In my days, I've fought a lot of enemies, Robot Maters, fake aliens, real aliens, but never was I given an opponent. These were the moments that changed me forever, was it for the best? I might never know for sure. This is the story of the one enemy only I could defeat, and the one enemy that I couldn't fight. This is the story of a boy who was the ultimate victim, and a boy who was the ultimate villain. This is the story of Kai Saibo, the ultimate opponent.

After battling Wily six times, I felt a sense of fulfillment knowing he was finally in prison. It's kind of funny, my worst villain fought me while Wily was still in jail. I thought nothing could go wrong, but everything went wrong in my life in just a few days.

This story, like every other story started out just fine. I was having a normal day in the normal Light Labs, "Rock. Can you get me those papers I filed away yesterday on the Concrete man designs?" My creator, Dr. Light asked.

"Sure thing!" I said. Light Labs had a lot of projects, a lot, so it was common for a few of the documents and designs to get mixed up, no big deal, just put them in their proper files and it's over. But there was one file I found that day that caught my attention. It was an old design from when Light Labs did military research back when it first started out. Back when Dr. Wily was friends with Dr. Light. I had seen a lot of the work done in those days, especially when Dr. Wily was using them to kill me, no big deal. But this document was different. It was for a project that never even got close to being green lit. It really intrigued me.

I spent a while reading the document, until Dr. Light called out to me. "Rock! Where's that document I need?"

'Oh right, the document, better get it to him.' I hid the mysterious document underneath the file cabinet so I could find it when I wanted to read it after I was done in the lab. I grabbed the Concrete man documents and bought them to Dr. Light. "Sorry it took so long. It was put in the research category instead of the construction category, so I had a hard time finding it." That was a lie of course.

"It's okay." Dr. Light said. "You can go back to the house now, I won't need anything for the rest of the day."

"Okay." I headed off to the house right next to the laboratory, on my way I grabbed the document so I could read it. "See you later!"

In my room I read through the document, it was by far the most powerful project Dr. Light ever designed for the military, he's made powerful Robot Masters, but they weren't for the military. It was strange that the project was turned down. It would be incredibly powerful and effective in wars, but it did seem a bit unethical. The Bogu Project. A kind of weapon connected to the human body, powered by oxygen and containing living cells. A weapon that could never run out of ammunition. But the ultimate price had to be payed though in order for the project to work. It required amputation of multiple limbs, probing in the brain, and it took years to develop the actual living tissue. So it made sense that the project was turned down. But it still seemed strange that the military of all people shut it down, yet they accepted killer robots. 'What is the Bogu Project really hiding?'

"Rock?" Roll, my house keeping robot sister asked from the other side of the door to my room. "What are you doing in there?"

I quickly hid the document and grabbed a book. "Oh, just reading. You can come in if you want."

Roll entered my bedroom. "What are you reading?"

"Uh..." I looked at the book, "The Art of War." 'Wait, I have that book, since when?'

"Oh! Cool." She said.

"So, what do you want?"

"Oh, nothing, I just felt like talking since we haven't really had the chance since the tournament incident a few months ago."

The tournament incident. 'I can't believe it's already been two months since that happened.' The tournament incident, as we often refer to it, was when a large robot fighting tournament was held, but it was interrupted when Dr. X showed up and reprogrammed all of the fighters to turn against humans. Robots fighting humans, it was an absurd idea that broke the three only laws we had, disgusting. Of course it turned out in the end that Dr. X was actually out good friend, Albert Wily, who always seemed to be a pain in the butt. Luckily we finally got him in prison after the tournament incident. "Yeah, I guess we really haven't talked that much. I'm sorry, I've had a lot of stuff to do for Light and a lot of events to attend. I'll try to talk to you more often, sis."

Roll hugged me very tightly, tight enough to crush the metal that made my skin. "I love you, big bro."

"I love you too, sis. Now, can I get back to my book?" I was too excited to finish the Bogu document to care about my sister and how she felt. "Please, I promise we can talk when I finish the book."

"Okay, Rock." Roll walked out of my room and continued cleaning the house.

I pulled the document from under my blanket and continued reading it. The research and data shown in it was revolutionary, it was the bridge between human and robot. The entire document was just genius. I stayed up all night thinking about what I read, I didn't want to power down, it was all just too amazing. I just could't believe no one had used this research, but I was happy no one had used it, it would have been catastrophic if anyone like Wily got their hands on it.
