Name- Tenshinhan
Race- Chikyuujin

Tenshinhan, along with his companion Chaou-zu and the assassin Tao Pai-Pai, was a student of Tsurusennin, who was a long time rival of master Kamesannin. The humiliating training at the hands of Tsurusennin gave Tenshinhan the desire to become the strongest fighter in the world. He is first seen at the 2nd Tenkaichi Budokai that Son-Gokou enters, and one of his ambitions at the beginning is to become an assassin like the young brother of Tsurussennin, Tao Pai-Pai, which was killed by Son-Gokou. Tenshinhan wins the tournament defeating Son-Gokou at the final, in an extreme close match, also during that final confrontation with Gokou, Tenshinhan rejects his evil ambitions and abandons Tsurusennin, after realizing the lack of honor of his teacher. Tenshinhan and Chaou-zu then become friends to Gokou and the rest of the gang. Although he started as evil in the beginning of the series later on we learn that Tenshinhan is a very honorable fighter, that like Gokou likes a good fight and is constantly willing to train to improve skills.

Tenshinhan has three eyes (providing him of an above normal vision), he is tall and muscular and is one of the strongest and fastest characters in the series in the beginning, only surpassed eventually by Piccolo and Gokou. He is also able to communicate telepathically with his friend Chaou-Zu. Later on in the series Tenshinhan, alongside with all the non-saiyajin (expect Piccolo) becomes way surpassed in terms of fighting power and has to stay out of most of the combats. Tenshinhan possesses an ability of reproducing any fighting technique that he sees, like he did with Kamehame-ha and Mafuba. He was also the first one to do such moves as the Tayoken (the move of the sun), Ki-ko-ho, multiple transposition (the ability to divide in four), and the technique of growing additional arms. During the Vegeta saga Tenshinhan dies while doing a Ki-ko-ho and is trained by Kaiou-sama in the afterlife. Later on, the only time where Tenshinhan is seen gaining some form of relevant role, is when he is fighting the 2nd stage Cell (before he engulfed #18) using the Ki-ko-ho and actually managing to doing some damage to Cell, of course he would eventually die because he couldn't handle the enormous energy that such move requires and is saved by Son-Gokou.

Tenshinhan goes to live with Chaou-zu and Lunch (which always had a crush on Tenshinhan) and his importance on the series reduces drastically. In Dragonball GT he is only seen during the evacuation of the planet, when the Earth is going to explode.

"Altough Tenshinhan becomes the strongest Chikyuujin of the Z warriors, afterwards the only time where he is seen gaining some form of relevant role, is when he is fighting the 2nd stage Cell (before he engulfed #18) using the Ki-ko-ho and [...] etc...

This was not done by me. It was made by Son-Gohandre as a favor to me.
