Cho Badeleg was a scientist of the Human variety, and of male gender, who worked at ExGal-4 on Belkadan in the year 25 ABY. Along with Danni Quee and Bensin Tomri, he traveled to Helska IV to examine what they thought was an extragalactic comet impacting the desolate surface of the planet's landscape. However, they were subsequently abducted by the actual inhabitants of the planet, the Yuuzhan Vong, under the command of Prefect Da'Gara. Tragically, Badeleg died as a result of the crash.
