Teek, a Neimoidian of the male persuasion, was the sibling of Jeek, his twin. In the xenophobic Empire, the brothers, an unusual achievement for non-Humans, both declared themselves to be tier-six inventors within Research Corps Eight of the Imperial Science Bureau. The pair journeyed to Tatooine amidst the Cold War, and at separate Imperial outposts, they each requested assistance from an Imperial who happened to be passing by to aid in trialing new battle droids.
