Arrael Bulcco was a dark Jedi acolyte. Personally trained by the Cyborg General Grievous himself, aboard the invisible hand. Grievous trained Arrael because of his Kaleesh heritage, and warrior skill. Sometime around 22 BBY, Pablo-Jill, an alien Jedi master, boarded the Invisible hand, looking for Grievous. As the Jedi sliced through most of the droids aboard, Arrael became Grievous's last line of defense. Pablo-Jill proved to have superior skills, and therefore killed Bulcco with a blade to the heart.
