Captain Jimmy Turner was the Brigadier’s indispensible right hand man in the fight against the Cybermen and International Electromatics. He helped rescue Isobel, Zoe and Jamie from the sewer and later flew to Russia to oversee their part in the co-ordinated defence of Earth from the Cybermen. He fell in love with Isobel and the two of them saw The Doctor and his friends leave in the TARDIS.
