Thomas H. Norstein

Tohma H. Norstein (トーマ・H・ノルシュタイン) is a fictional character in the anime series Digimon Savers. In the Japanese version he is normally voiced by Hirofumi Nojima; Yuko Sato voices his younger-self.

Tohma is a 14-year-old boy genius who graduated from the Stockholm Royal University of Science at the age of 12. His abilities are considered elite, even within DATS. He bases his operations on data and theoretical principles, and as such his personality clashes with Masaru's. His mother is Japanese and his father is a prominent Austrian aristocrat. Calm and shrewd, he is the exact opposite of Masaru and sees the other boy as a rival. He has an elitist attitude but he gets emotional when thinking of his mother, who died years ago when he was young.

Tohma's partner is Gaomon, who feels that Tohma is someone to loyally follow and obey. Tohma sees the Digimon as a good friend.Also, Gaomon calls Tohma as his "Master". When Gaomon comes out of the digivice he readlly says "yes master" in the Japanese version.

A great deal of Tohma's backgrounds comes in episode 15, when MetalPhantomon manipulates his mind, feeding Tohma nightmares from the past. We learn his mother died in a horrific accident in which she was killed by a speeding truck. However, the nightmare does not have the entire desired effect on Tohma, and he pulls through, allowing Gaomon to evolve to MachGaogamon.
