|Appearance:||The Ribos Operation|
|Main actor:||Iain Cuthbertson|
Garron and his younger assistant, Unstoffe, embarked on a career as galactic swindlers, selling planets to unsuspecting victims. In what Garron had promised Unstoffe would be their last mission, Garron tried selling Ribos to the Graff Vynda-K using a lump of jethrik, which turned out to be the first segment of the Key to Time, attempting to create the impression that jethrik was common on Ribos.
When the Graff found out the truth, Garron and the Fourth Doctor were forced to work together to escape his vengeance. Garron eventually ended up with the Graff's spaceship, filled with eighteen years of plunder, although the Doctor took the jethrik from him despite Garron's attempt to steal it back.
