A list of all the viruses in Mega Man Battle Network 5. Note: If the portal to Nebula Area1 is open, all level 1 viruses become level 2 viruses. If the portal to Nebula Area3 is open, all level 2 viruses become level 3 viruses. Level 2 and 3 virus locations are only listed in areas where they are the lowest level of virus that can appear (i.e., in Nebula areas).
