Doctor Vicktor is a Transylian from Anur Transyl. He works at NASA to obtain the means to hijack a space shuttle. Despite his size, he possesses excellent reflexes, as he was able to quickly spin around and backhand a super-speeding XLR8 when the latter attempted a sneak attack on him. He is intelligent, and working for Zs'Skayr; his immediate plan was to resurrect his master, whose ultimate plan was to prevent the sun's light from reaching the earth using various satellites(therefore meaning that Zs'Skayr would be at full power all of the time). He is not treated with respect after Zs'Skayr is resurrected. After he asks why they need Ben, Zs'Skayr takes control of his body and throws him around. He serves as the unofficial leader of the three horror-themed aliens. The purple lightning that the previous two horror aliens appeared in was generated by a teleportation machine that he uses. His first appearance is in The Return, where he succeeds in resurrecting Ghostfreak. In the next episode Be Afraid of the Dark, Ben fights Doctor Vicktor and Zs'Skayr on Earth. Ben accidentally gains use of Doctor Vicktor's form when Vicktor finds Ben and grabs him by the wrist, unintentionally adding his DNA to the Omnitrix which gave Ben the alien he calls Benvicktor. Vicktor essentially defeats himself near the end of the episode. In an attempt to teleport Ben to an unspecified location, he and the mummy alien are tossed into the portal he created.

The video game Ben 10: Protector of Earth features "Vicktors" as enemies from Zs'Skayr's planet based on Dr. Vicktor.

It is explained that back when Zs'Skayr was still inside the Omnitrix, Ben used him to sneak into a horror movie, at which point he was overtaken by the alien, who contacted Doctor Vicktor with his plans then transformed back knowing nothing.
