First Morbius

A Gallifreyan criminal sentenced to execution, Morbius escaped death by having his brain removed before his disintegration by Dr. Solon. Solon took the brain and went into hiding on the planet Karn, where he began planning to build a new body for Morbius out of parts salvaged from corpses found in the wreckage of spacecraft Solon lured to the planet.

Though Morbius's new body was horrifyingly grotesque, leading the Doctor to mock him as "Emperor Chop Suey," Solon's ability to merge alien tissues together did give Morbius at least a few advantages over his previous biological form, including lungs from a Birastrop capable of withstanding cyanide. Other parts of Morbius' body included a human left hand which came from Solon's unknowing assistant, a giant lobster-like right hand, and a humanoid torso. Solon required the head of a Time Lord in order to safely house Morbius' brain, but when plans to use the Doctor's head failed, he resorted to an unproven, experimental braincase which included two stalklike eyes.
