Bohandi

Bohandi is a species native to unknown Water planet. It is (unlikely) dominated by females, although they never leave their homeworld (except to colonies). They most - known colony is Alpha Centauri Prime, which is also the closest to Earth.

History
Bohandi makes contact with Ansoids, although both races leave each other alone. They also contacted birds-shaped colds, which resulted a long - time war. Birds-shaped call for help to their allies, including species later known by humans as Greys. That resulted birds-shaped retreat to their home system and Bohandi attack to Greys. Bohandi was able to create a virus, deadly as to Greys as to Reptilians and Insectoids. They fire torpedoes with that virus to Greys ships and let them dies. Later, Greys abducted humans to find a cure to the virus. (Aliens)

Later after that, Pigs started to expand it power. They become Bohandi allies and attacked Icer ship. Icer escaped and landed on Earth, although pigs stolen his end Birds eggs, that resulted Icer, Birds and Sojuz (with crew of amazons) to chase pigs. Pigs landed in Bohandi's Alpha Centauri colony and that become first contact between humans and Bohandi. Bohandi and pigs was defeated, although Bohandi colony survived. ( Space mission of Birds)

Year after that, Swallows, Amazons and Birds arrived to birds-shaped home system onboard the Chukspace. Soon after that, Bohandi attacked that system and Chukspace destroyed they main ship. That resulted a start a cold war between humans and Bohandi. (In the land of Icer)

However, few years later, Agmat allied with Bohandi to conquer Earth. They build base on Pluto and star Galaxy - wide War of three Worlds. Chukspace again destroyed Bohandi base, then their homeworld was attacked and contaminated. Some of Bohandi escaped, but at least 90% of them was assimilated by The Borg. (Pig's new inventions)

However, survived Bohandi, along with Pigs, was able to construct the Time Weapon, and, although of send a Jonh team, they fired on Earth, conquer it by changing the timeline. However, second fire ( to birds-shaped homeworld) was sabotaged and entire weapon was sucked into "fluid space-time". Then, its structure was changed by Peggy (who infiltrated them, posing as Earth outcast) and was destroyed after emerging on Earth orbit. (After fact, Fluid time, Aliens)

But history was changed. Emerge was in past and Bohandi conquered Earth in this timeline. Jonh's team (with Peggy) worked with Greys to restore timeline. At end, after destroying Bohandi mining station at Coridian system, they made time weapons unable to exist and they restore timeline. Before return to the future using Greys ship, they gives them a cure to virus: human's hemoglobin. (Aliens)
