Mega Man Star Force takes place in the fictional year of 220X where two hundred years have passed after the finale of Mega Man Battle Network series, when emphasis on internet technology has lessened, and instead, the world has become networked through use of EM Waves. Though cyber worlds and NetNavis still exist in Star Force, human dependency on them has greatly decreased, and people no longer have Navi companions. instead relying on Transers. Three large satellites orbiting the Earth—Pegasus, Leo, and Dragon—power the EM Wave World that exists around the Earth's atmosphere, keeping the world networked. While the EM Wave World is normally invisible to the human eye, a special piece of eyewear called the Visualizer (possessed by the series's main protagonist) allows a human to see this other world. However, like with the cyber worlds of Battle Network, EM Wave Viruses inhabit the EM Wave World, causing problems in everyday life.
