The Yaka were a race of Near-Human cyborgs hailing from the Yaka system. Centuries before the rise of the Galactic Empire, the neighboring Arkanians, known for their genetic experiments, implanted the naturally dim-witted race with cybernetic implants. Some Arkanians saw this effort as something benefiting the brutes, while other socially conscious Arkanians questioned the ethical implications of such an act.
Yakas appear as tall, brutish-looking, near humans with obvious signs of possessing cybernetic implants. Their average height was around 2 meters and they possessed a large frame with limbs to match. A Yakas face commonly lacked expression whatsoever, this was due much to the cybernetic brain that is implanted at birth and was what gave them genius-level mental abilities. This modification is what made the Yakas one of the most intelligent and technologically advanced species in the known galaxy.
A sometimes dangerous side effect from the cybernetic tinkering done in a Yaka's brain was all Yaka were left with a severely twisted sense of humor. Their minds raced with accelerated thought processes and were quickly bored by their own thoughts. They kept themselves occupied by making sarcastic comments and playing practical jokes on others. They also seemed to have an uncanny ability to find irony in grim situations when others didn't.
Yakas bore children like most humanoid species and chose to implant their children themselves, desiring them to have the same intelligence they possessed. An interesting note on the implants throughout their bodies was their similarity to the cybernetics found in Ganks, except that they were far more advanced. Senior Anthropologist Mammon Hoole was noted to have made a comment about Gank circuitry being the beta testing for the final implementation on the Yakas.
