The year 20XX. It has been several years since the Roboenza outbreak, and no one has heard from Dr. Wily since. Dr. Light and Dr. Cossack, thinking about the past and looking toward the future, agreed to work on a massive robot database, which would compile all the robot data throughout the world into a single, detailed system so people could reference it in the future. Robots would be able to "upload" themselves into this database, and hone their skills against the data, which would lead robotkind to a stronger, smarter future.
After months of finding and compiling this data, Light and Cossack are prepared to unveil a prototype of the database to the public and demonstrate its features (Even if the system still had some bugs). Little did they know that there were two surprises waiting for them there that night, the first of which was Dr. Wily hiding in the audience, watching the unveil. The second surprise would prove to be much more devastating. The public unveil seemed to be going fine at first, but in the middle of a test run, a pair of curious alien robots appeared!
The robots Light and Cossack had assembled there were helpless against them, and once defeated, they use an arcane power to digitize robots and humans all over the world into the Prototype! The robots proclaimed that humanity would have to fight one another to the top and defeat them in order to reclaim their freedom. And thus began a mad scramble for humanity to raise their own digital robot armies and lead them into combat against one another...
