Gomer

Gomer was the Surgeon General of the High Council. When the Fourth Doctor returned to Gallifrey with the intention of assuming the office of Lord President, Gomer was in his tenth regeneration.

Gomer was of strong enough character to argue with both Chancellor Borusa and the Gold Usher when the Fourth Doctor was apparently rejected by the Matrix.

He joined Leela and the Outsiders when they raised a rebellion against the Doctor. (TV: The Invasion of Time)
