- You may be looking for the Gond scientist named Beta.
Beta, along with Alpha and Omega, was one of the first ever Daleks made into humanised Daleks by the Human Factor in an experiment by the Dalek Emperor. (TV: The Evil of the Daleks) Beta survived the Dalek Civil War on Skaro and joined the other humanised Daleks when they travelled to the planet Kyrol. Here they survived and bred. However, they were manipulated by Kata-Phobus, a telepathic parasite. They destroyed themselves to prevent it from feeding on them. (COMIC: Children of the Revolution)
