Kraals
The Kraals were a race of technologically advanced humanoids that were native to the planet Oseidon. They were forced to look for new planets to inhabit due to the higher levels of radiation on their homeworld.
They created androids that could mimic other species that were nearly indestructible. They also created a virus that was contagious and deadly, so deadly that it could prove fatal in seconds.
