Tenshinhan is a fictional character from the Dragon Ball metaseries and the franchise equivalent created by Akira Toriyama. Trained by Muten-Rôshi's rival, the Crane hermit he starts out as an enemy of Son Goku, but soon makes peace and becomes an ally. He is usually accompanied by Chaozu, his training partner and best friend, whom he can communicate with telepathically. Tien Shinhan has a unique physical composition as a throwback to his ancestors, the Three-Eyed clan. He has the ability to grow arms from his back, split into four people, and he achieved his third eye through deep meditation. During the early years of his life, Tien entered Master Shen's Crane School. There, he learned powerful ki-based techniques such as the Dodon Ray and the Tri-Beam, and he was taught defensive techniques by Master Shen's younger brother, Mercenary Tao. At the time of his introduction, Tenshinhan is among the most powerful warriors in the series, matched only by Goku himself. Heavily devoted to martial arts, reclusive and disciplined, Tien Shinhan is one of the strongest Humans within the Dragon Ball universe. He battles alongside the other Z Fighters when major threats to the Earth surface, often courageously engaging enemies far more powerful than himself. As is the case with a handful of other characters from the early chapters of Dragon Ball, Tenshinhan was inspired by a character from Journey to the West; his unique feature of having a third eye was derived from the Chinese god Erlang Shen. According to the Daizenshuu book 7 and the PlayStation 2 game Dragon Ball Z: Budokai Tenkaichi, Tenshinhan belongs to the alien race of the "Three-Eyed clan." (Source: Wikipedia)
