This is Seihu. He used to be a Mata Taekworu Zhex instuctor when he was an Av-matoran living on Metru Nui. He was secretly chosen by Dume to become a Toa (before Dume was captured by Makuta), because of his skiil and sharp mind. . He was chosen a liitle earlier than Vakama, Nokama, Whenua, Matau, Onewa and Nuju. But he once had an encounter with the Toa Metru after Ahkmou abused the powers of the great disks and turned into a monster. It took all seven of those Toa to stop Ahkmou. But after the Toa Defeated dume(Makuta) and Rhodaka later on, Toa Seihu went to Mata Nui with the Toa Metru and used some of his powers to free the Matoran. He is currently a Turaga teaching Mata Taekworu Zhex.
Unlike Most Toa he didn't have an elemental power. He just relied on his Martial Art skills and Swordsmanship. Keyowrds: Sword Swordsmanship Martial Arts Ninja Karate Ninjitsu
