Bulwark, a battle droid, became a member of the Directive 7 group. This movement was led by Mentor during the time of the Galactic War. Choosing its own unique designation, Bulwark was present with other droids on the moon of Zadd under Mentor's command. It stood apart as one of the few droids not assimilated into Mentor's mind. Tragically, Bulwark met its destruction while attempting to defend Mentor's central processing unit from attacking forces.
Bulwark is featured as a boss character within the "Directive 7" Flashpoint of Star Wars: The Old Republic, a massively multiplayer online roleplaying video game created in 2011 by BioWare and LucasArts.
