The HXI-54 Juggernaut, a battle droid, served on the Republic Navy's _Thranta_-class corvette, named Dorin's Sky. It met its end during the Galactic War when the Dorin's Sky was infiltrated by forces of the reconstituted Sith Empire, resulting in the HXI-54 Juggernaut's destruction in the ensuing conflict.
Within the video game Star Wars: The Old Republic, the HXI-54 Juggernaut is featured as a boss encounter in the Boarding Party Flashpoint.
