Rivesh Mantilax

Rivesh Mantilax the husband of Seruba Velak.

Biography
Rivesh worked in genetic warfare for his kind, and was the designer of a genetic weapon that would kill all Viperox in the universe, to which the Tenth Doctor objected. When the Viperox went to war with his kind, his side lost. His wife, Seruba Velak, had already crashed in Roswell. As soon as he could, Rivesh went to find her. When his ship was gunned down by the US Military near Area 51, he was saved by Night Eagle and hidden in a cave. Four years later, Night Eagle took the Doctor, Cassie and Jimmy to see Rivesh, who told them his story. Just moments afterwards, General Stark walked in and attempted to arrest him.

He locked him up in Dreamland, seperated from Seruba Velak by a panel of glass. Just as his enemy Lord Azlok escaped from the Area 51 base, he was attacked by him. Seruba and the Doctor later went on a search to look for a cure to revive him, located in Seruba Velak's ship. They were successful in their mission and arrived in the Doctor's TARDIS, which was delivered by Jimmy and Cassie. Seruba revived Rivesh and he activated the device, which the Doctor modified with his sonic screwdriver to emit a high-pitched noise, amplified by the TARDIS, that could only be heard by Viperox. They fled Earth back to Viperon, with Rivesh and his wife able to return to their own home. (DW: Dreamland)
