Dr. T is the one who explains tips, techniques, tips and trivia about basketball. He appears on many episodes during Shohoku matches, especially "teaching" Hanamichi Sakuragi must-learn basketball moves the latter does not know about. The character seemed to be short and gives comic relief as he appears. The character himself is based on the author Takehiko Inoue and voiced by Yoku Shioya.
