Dark Miyabi

A descendant of the secret Miyabi ninja clan and a high ranking assassin for hire, Miyabi is referred to as "General Miyabi" by some of his colleagues. At some point, Dr. Wily revived the deleted ShadowMan and gave him to Miyabi, and from then on he became the ninja NetNavi’s operator. Despite first appearing and helping Netto Hikari, it is later revealed that before the Neo WWW was defeated, Tesla Magnets hired him to delete Rockman, though no matter how hard he tried he was unable to, with fate itself seemingly saving Netto at every turn. This, combined with Wily informing Miyabi that the fate of the world depends on Netto, leads Miyabi to become his ally. When merged with ShadowMan through Cross Fusion, Miyabi becomes C.F. ShadowMan.
