Kazon

The Kazon are a sapient, but aggressive humanoid species hailing from the Delta Quadrant. They are known to have had first encounters with the United Federation of Planets during the 2370s, namely with the U.S.S. Voyager.

Biology
Though greatly similar to humans, Kazon are known to have several differences. One such difference comes in the form of their distinctive ridges on their forehead, as well as their skin color. There are at least 2 different color skin tones for the Kazon, most of them being of copper skin tone with brown skin tone being the minority. Their hair also comes in colors of either black or brown, however unlike humans, who have individual strands make up their hair, most of their hair is in chunks.

History
The Kazon were known to be slaves under the control of the Trabe, who were responsible for conquering their home. Whether their sects existed prior to their enslavement or not, what is known is that the Trabe kept them in line by having them fight among themselves. This changed however when Jal Sankur told the sects to put aside their petty squabbles and unite against their oppressors. This resulted in the Trabe losing their slave force and much of their technology.

Following this, the Trabe would become nomadic, as the Kazon ensured them they would never find a place to call home again.

Technology
As stated before, Kazon had no real technology of their own. Most of what they had was stolen from the Trabe, but they were able to master the usage of such technology. They are capable of warp drive, possessing deflector shield, tractor beam and energy weapons technology. They however lack technology, such as the transporter and replicators, which they sought during their encounter with the USS Voyager.

Despite their technology however, the Kazon have never been assimilated by the Borg, as they find their technology "inferior". Assimilating their technology and biology would be nothing but a waste of time for the Borg as a result. They are known to possess medicine, however not as advanced compared to the Federation.

Kazon possess several different types of spacecraft, which they use against their enemies, including other Kazon factions. All of which were once vessels used by the Trabe they served.
 * Fighter: A much smaller version of the Raider, the fighter was an attack ship capable of complimenting of a single pilot. These vessels were armed with bow particle weapons, as well as a ventral torpedo launcher and deflector shields.
 * Shuttle: Possibly the smallest vessel the Kazon possess, the shuttle is capable of transporting 3 troops at any given time. Some of these have been reinforced to the point where they can pierce the hull of an Intrepid-Class starship.
 * Raider: Raiders were larger patrol craft, technologically limited, but very fast. Raiders were armed with 2 particle based weapons on their bow, as well as capable of dispensing variable yield photonic charges.
 * Predator-Class: The largest ship the Kazon operate, the Predator-Class ship is probably considered the highest in threat level when it comes to the Kazon. These ships are armed with various particle cannons, as well as capable of launching powerful plasma torpedoes. They were shielded, however couldn't withstand a direct attack against sustained fire from a phaser or photon torpedo. They were also clumsy at impulse, giving a ship with manuverability the advantage.
