Biography
K'anpo served as the abbot of a Buddhist meditation centre in England with his assistant Cho-Je, a projection of his next incarnation, presumably due to his own infirmity. K'anpo showed the mentally disabled Tommy compassion, leading to him considering the abbot a friend.
The Third Doctor and Sarah Jane Smith met K'anpo at the meditation centre when the Eight Legs infiltrated his centre. Upon meeting him the Doctor apologised to him in Tibetan for not bringing a cotton scarf as a ceremonial gift, not initially recognising his former mentor. The two discussed the blue crystal that the Doctor took from Metebelis III, and K'anpo suggested that they should give it to them, knowing it would be their undoing. He also realised that Sarah was possessed by Huath, and used the blue crystal to free her. The Eight Legs used the students as human hosts to strike down K'anpo. He then regenerated into Cho-Je.
