Lo Bukk was a Zabrak male who served the Jedi Order as a Padawan during the final decades of the Galactic Republic. Around 67 BBY, he and his Jedi Master, Ni-Cada, were sent by the Order to the world of Abraxin to investigate the continuous killing of marsh haunts, which were being carried out by the Force-sensitive Nautolan Naat Lare. On the planet the Jedi unknowingly crossed paths with the Muun Sith Lord Darth Plagueis, who was also looking for Lare. After Plagueis managed to make contact with Lare, the Muun convinced him into taking the offense against the Jedi as proof of his worthiness to join the Sith; the resulting skirmish was short, in which Bukk's Master killed Lare.
