At the beginning of "Axess", Lan manages to use the then-untested Synchro Chip to Cross Fuse with MegaMan and defeat the Darkloids that materialize in the real world with the aid of Dimensional Area Generators. Because of this, Lan is invited to become a NetSaver (Net Savior), an Official NetBattler charged with protecting the net. As a result of Cross Fusion, MegaMan loses his Style Change option, but instead gains the ability to use Double Soul (Soul Unison) with which allows him to combine his powers with other NetNavis, harkening back to the original Megaman's Power Copy ability. Cross fusion also multiplies Megaman's power level (For example, the megabuster does much more damage in cross fusion), while making Lan lose his energy. Much of the series is devoted in dealing with the problem of the addictive Dark Chips and the criminal syndicate, Nebula who is controlled by Dr. Regal.
