Viperox

Viperox were insectoid war-like species.

Biology
The Viperox are larger than a human being, they are insect like in appearence. They have Super Hearing, which the Doctor told Cassie Rice. They could shoot spikes out of their hands. Since they are not mammals, they laid eggs using a Viperox Queen. (DW: Dreamland)

History
The Viperox were on the brink of war with the Gray aliens, a war which happened due to the Gray ambassador, Seruba Velak, being shot down by pirates. They destroyed and wiped out most of the population. They chased another Gray, Rivesh Mantilax, to Earth. Soon after this, the Viperox invaded Earth in the 1950s. Their leader Lord Azlok made deals with the US government including making a deal with General Stark, in exchange for destroying Russia with the genetic war device that Rivesh Mantilax carries. They intended to betray Stark, however and sent out an Alliance of Shades to retrieve it. They planned to invade Earth using thousands of Viperox eggs hidden under a ghostown with the Queen. Stark betrayed the Viperox first, and they now have the entire U.S. military against them. (DW: Dreamland)
