Zantoxian trade vessel

Trade vessels were operated by the Zantoxians. One such vessel which passed through Earth's solar system in the 2000s had their onboard computer secretly accessed by Mr Smith. Via a cybergon download, Mr Smith's gained an up-to-date data registration of the Uvodni general, Uvlavad Kudlak, allowing him to reveal to Sarah Jane Smith the identity of Kudlak, who she discovered was operating on Earth.
