He was assigned to infiltrate Kaled military headquarters and uncover their secret plans. He encountered Davros while posing as a Muto in the Wastelands shortly before he was captured by a Thal squad. He later infiltrated the Kaled Dome and posed as a Kaled military officer. He discovered Davros' genetic experiments but was captured by Nyder.
Davros, recognising him as a Thal spy, made Baran the subject of his next operation, the first to be performed on a Thal. After irradiating and augmenting the brain, Davros had it transplanted into a Mark I travel machine, thus creating the first prototype Dalek. (AUDIO: Guilt)
