This article is about a/an villain in Kamen Rider 555.

Dr. Masahiko Minami (南 雅彦 Minami Masahiko) is a high officer of the National Police Agency and the leader of actions against Orphnochs. Secretly, he acts as a scientist working with Smart Brain to turn Orphnochs into living weapons. He is also a major antagonist in Kamen Rider 555, being indirectly responsible for Yuji Kiba's later vengeful atrocities against humans.


Acting as the high officer of the National Police Agency, Masahiko Minami is an extremely xenophobic madman who believes deserves to be experimented for their inferiority and that humanity will not be "pure" if they accept the Orphnochs. He is first seen stopping a police investigation into Yuka Osada, secretly planning on using her for one of his experiments. After making a deal with Smart Brain to use Orphnochs as weapons, Minami captures Yuka Osada and electrocutes her as part of his experiment. Yuka was later saved by the Crab Orphnoch, so Minami sent a squad of armored officers after her, Yuji Kiba and Takumi Inui.

Following Yuka's death, Minami's is chased down and killed by a vengeful Kiba. Before dying, Minami mocked Kiba that the Orphnochs would never win against humans.
