Ral

Scientist Ral was a member of the Scientific Elite. He attempted to warn Davros of the Thal attack on his lab, and later gave him a poison injector to kill himself. (BFA: Davros, BFD: Corruption)

Ral later betrayed Davros to the Thals, as he had come to be disgusted by his morals. He accompanied Colonel Murash back to the Thal city. He was shot and killed Nyder, who led the rescue team to free Davros. (BFD: Guilt)
