Jeek was a male Neimoidian and the twin brother of Teek. Both brothers proudly claimed themselves as tier-six inventors of Research Corps Eight of the Imperial Science Bureau, a rare feat for non-Humans in the xenophobic Empire. During the Cold War the two brothers traveled to Tatooine, where stationed at two different Imperial outposts each of them asked the same Imperial passerby to help with testing of new battle droids.
