Solon

Dr. Mehendri Solon was a human physician and scientist of great renown, and a follower of the Time Lord tyrant Morbius.

Profile
Solon grew up on Earth. (DW: The Brain of Morbius). At some point, Solon authored a famous paper on microsurgical techniques in tissue grafting, which the the Doctor had heard about. After writing and dogged by rumors that Solon had joined the personality cult of Morbius, Dr. Solon went into hiding on the planet Karn.

Though thought executed, Solon had saved Morbius's brain and kept it alive. ([[DW: The Brain of Morbius, PDA: Warmonger)

On Karn, Solon developed the techniques which enabled him to create a new body to house the still-living brain of Morbius, now believed executed. In an isolated castle on Karn, Solon was assisted by his simple Dravidian servant Condo. Spaceships often crashed on the planet, and Solon constructed a horrendous patchwork body out of the alien survivors' body parts, including a Mutt and a Birastrop. He planned to house Morbius' brain in it.

When the Doctor and Sarah Jane Smith arrived, sent by the Time Lords, Solon needed only a head to finish his monstrous creation, and hoped to use the Doctor's. In his last moments, he managed to complete the surgical work on new Morbius, before the Doctor killed Solon by creating cyanide gas and blew it into his laboratory, an action which had no affect on Morbius himself.
