Klarimo

Klarimo was a scientific genius from the Outerfringe Star Cluster. He led the Outerfringe Forces in an attempt to invade Tiro and conquer the Staggs, but was defeated by the First Doctor and Stagg leader Argon. Klarimo was supposedly returned home via the Molecular Shaft, but a malfunction transported him to an underground chamber, where he rematerialised as an energy being. When he started poisoning the Staggs' water supply, Argon and a team of Staggs traced the problem to the source, where they were reunited with the Doctor. Working together, they realising that the chamber was underneath a volcanic crater and had it blown open with explosives, allowing Klarimo to return home. (PROSE: Terror on Tiro)
