Morgan was Captain Dent's second-in-command on the IMC expedition to Uxarieus in 2472. He used an IMC robot and projections to make it appear that giant lizards were attacking the colonists living there. Morgan attempted to kill the Third Doctor with the Robot on orders from Dent. Dent sent Morgan and Caldwell to investigate the Adjudicator's (really the Master) spaceship, and Morgan found the key to his spaceship.

He was later shot and killed in a shootout with the colonists. (TV: Colony in Space)
