rockman online
Rockman Online (록맨온라인) takes place in the far future, where the characters from the Rockman and Rockman X series had long since passed away, including the Irregular threat.
Believing the threat of Irregulars are gone for good, society is taken by surprise one day when a large number of Irregulars began to wreak havoc. In response, the UCA (United Continent Association), initiates the production of copies of X, Zero, and Duo, among other heroes, to combat the rampant Irregulars. The UCA went so far as to embed the DNA Souls of the original heroes onto a chip housed within the copy bodies to further enhance their abilities in an effort to make them as legitimate as possible. The Irregulars associated with Rockman Online are actually rebuilt and heavily customized versions of enemies from the past, produced in a similar manner to the X, Zero, and Duo copies.
