Kosh Teradoc

Kosh Teradoc was an Imperial Admiral in 13 ABY who traveled to the planet of Ryvester with the intention of collecting a valuable artifact from one Captain Hachat inside a bar. However, it turned out that Hachat was really Garik "Face" Loran of Wraith Squadron, and Loran and his teammates had lured Teradoc in with the intention of saving Dr. Cheems, a Mineral analyst who Teradoc was holding prisoner for his own selfish purposes. Wraith Squadron caused a commotion in the bar that allowed them to succeed in their mission of saving Cheems while Teradoc had collected his artifact.

However, as Wraith Squadron would later reveal to the saved Cheems, it turned out that the artifact was really a giant set of explosives combined together, meant to blow up and kill Teradoc from inside his own base on Ryvester. Sure enough, the artifact blew up as expected, but it is unknown if Teradoc was caught in the blast.
