He was known as the "Giant Devil" (ジャイアント・デビル, Jaianto Debiru).
He was a relatively calm and composed person. Toba usually had a serious facial expression and did not seem to show too much emotions. He was a proud fighter, from whom the real devil comes out only in the ring (hence his nickname). During his battles, he was not an extremely brutal and ruthless person, but he did not try to stop himself during a serious duel. He was also a very honorable fighter. He knew there was no chance of winning at the end of his fight with Baki Hanma, but he couldn't give up. It was his will that Baki knocked him out. After the fight, Toba told him that there is no honor in surrendering.
As a pro wrestler, it was very important for him to not disappoint his fans who loved him. Formely, he used to treat pro wrestling as a form of game to entertain other people. After meeting with his master Rikigouzan, he started to look at wrestling differently and took it very seriously. When his master was murdered in a street fight, Toba found that his fighting workout were weak, and he started to training very hard. He decided that real pro wrestling should never lose, neither in the ring nor in the street.
Mount Toba is a very tall muscular pro wrestler. He has short black hair.
He is a large pro wrestler known all over the world. He is not only big and strong, but also very agile. He can make a spin kick despite of being very big. He attacked Baki Hanma and Kaioh Retsu with karate chop before they could even react. Mount Toba has high durability.
