MegaMan.EXE

MegaMan.EXE is Lan's NetNavi (short for Internet Navigator). MegaMan.EXE is quite powerful, and along with his operator Lan, is a very skilled virus buster. He is also Lan's twin brother, Hub (Saito in Japan) who died at birth, because of a rare condition known as BHD (unknown meaning). Dr. Hikari then used his data to revive him as a Net Navi, MegaMan.EXE.
