Viperox

Viperox were an insectoid species of conquerors.

Biology
Viperox were tall, insectoid humanoids. They varied in appearance, but were blue-green, with a tough exoskeleton, long limbs and sharp claws. They also had eyes on stalks, mandibles and very acute hearing.

There were at least three types of Viperox:
 * Viperox Battle Drones were the soldiers and warriors of the Viperox, travelling in swarms of thousands. They had flat plates, four long mandibles and clawed hands, which could shoot out spines which exploded on impact. They had great strength, were resistant to bullets, had retractile wings and could dig through solid concrete. The battle drones were aggressive and would hunt for practice as well as food.
 * Above the battle drones were the Leaders, such as Lord Azlok. They were the smartest and controlled the rest of the Viperox. The lords were shorter than the drones, with more rounded plates, hands instead of claws and human-like mouths. They also had four wings, allowing them to fly.
 * The Viperox Queens were producers of eggs for the Viperox. They laid eggs by the thousands, allowing for the creation of armies. Though similar in appearance to the lords, the Queens were much larger, as well as having large abdomens swollen with eggs and four legs instead of two. (TV: Dreamland)

Culture
The Viperox created the Viperox Empire. During an invasion, the Viperox landed with a small number of Viperox and a queen, who would lay eggs. The eggs would hatch into battle drones, who would make up the invasion force. (TV: Dreamland)

Technology
The Viperox travelled in oval, organic-looking spacecrafts. They were covered in ridged armour, had 6 claw-like protuberances and an eye-like feature on the front. (TV: Dreamland)

History
In the 1940s, the Viperox were on the brink of war with the Gray aliens. The ambassador Seruba Velak attempted to negotiate in 1947, but was shot down by pirates and crashed on Earth. The negotiation fell through, and the war began, leading to victories by the Viperox.

In 1958, the Viperox, led by Lord Azlok, came to Roswell following Rivesh Mantilax, who had created a genetic weapon that could destroy their entire race. They set up a queen under the ground, laying eggs for an invasion force. Lord Azlok pretended to join forces with Colonel Stark, claiming that the weapon could be used on Russia. Lord Azlok also obtained an android from the Alliance of Shades, which he used to track down the weapon. By following the Tenth Doctor, Lord Azlok and Colonel Stark were able to get the weapon, but after the Doctor explained the Viperox's plan, the army severed ties with the Viperox. When the Viperox attacked, the Doctor was able to reprogram Rivesh's weapon, making it target the Viperox's nervous system and create an annoying supersonic sound. The Viperox were driven off and returned to their planet. (TV: Dreamland)


 * The Doctor frequently mentioned that the Viperox should not be destroyed as they would eventually become peaceful. Whether this is speculation or the true future is unknown, but considering how much the Doctor has explored the timestream, the latter seems likely.
