Nausicaan

The Nausicaans are an aggressive humanoid species native to the planet Nausicaa in the Beta Quadrant.

History
In 2058, Naussican raiders boarded the lost Vanguard colony. The inhabitants attempted to greet them peacefully, but to no avail. Over 200 colony residents were killed before the Nausicaans were driven off. The colonists referred to them as "tuskers".

Nausicaans often pirated smaller ships, attacking and stealing their supplies. 

In 2152, while time traveling, Doctor Phlox saw a possible future in which Enterprise was attacked by Nausicaan pirates.

Kajek was a Nausicaan Bounty hunter that was in the employment of the Orion Merchant-Prince Ganz. Kajek performed several missions for Ganz in the late 23rd century.

In the 2370s, Nausicaans were hired as bodyguards and enforcers, such as by Brunt of the Ferengi Commerce Authority or by the Orion Syndicate. 

In 2376 Nausicaan rogue agents attacked Starbase 92.

Iliana Ghemor used Nausicaans in 2376 and 2377. One served her aboard a Besinian freighter, while Savonigar was hired to kill the mirror universe Ghemor.

In 2380, a Nausicaan served as a bouncer in the Cantino, a bar on a space station near Idryll space.

In 2389 the Gorn Hegemony hired the Nausicaans to fight for them during the Klingon-Gorn War. Two years after the 2403 fall of Gornar, they signed a non-aggression pact with the Klingon Empire.

By 2409 many Nausicaans served in the Klingon Defense Force.
