Souther

Souther (サウザー, Sauzā) is the sole successor of the Nanto Hōō Ken (南斗鳳凰拳, 'Nanto Hōō Ken' "South Dipper Phoenix Fist) style and one of the Nanto Roku Sei Ken. Souther bears the destiny of the Star of Leadership (将 星, Shōsei), also known as Polar Star (極星, Kyokusei) and Star of the Southern Cross (南十字星, Minami Jūji Sei). The Star of Leadership rules over the other five stars of Nanto; therefore, none of the other Nanto successors can defeat him.

Souther establishes himself as Holy Emperor (聖 帝, Seitei) after Raoh's injury and becomes known as a cruel and heartless man, kidnapping children to build his Holy Cross Mausoleum. Souther was once warm and loving child, adopted by the wise master of Nanto Hō-ōken, Ōgai. However, because of Nanto Hō-ōken's awful legacy, Ogai tricked Souther into killing him in order to be surpassed by his student. Souther was devastated by his master's death, and crushed his emotions with hate and cruelty. After meeting Shū, Kenshiro fights against Souther and loses horribly when Hokuto Shinken does not work on Souther's body. After Shū's death, he fights Souther again and is able to discover that Souther has dextrocardia situs inversus totalis-- his heart is on his right side and his pressure points' positions are subsequently reversed from where a normal person's would be. He defeats Souther with a merciful "Ujō Moshō Ha", much to his surprise. Despite his tyranny, he is shocked that Kenshiro displayed mercy towards him. He then dies in front of Ogai's shrine, regaining his humanity. In the movie Raō Den: Jun'ai no Shō, his death scene is different than in the manga or TV series; there is no reference to his sensei Ogai or the motive behind the pyramid, also the scene where he embraces his sifu's body is omitted. Instead, he commits suicide by stabbing himself with his fist, refusing to die by Hokuto Shinken.
