Cassus Fett's Battle Armor was a uniquely crafted set of Mandalorian battle armor specifically created for and utilized by the Mandalorian warrior and strategic mastermind, Cassus Fett, before the outbreak of the Jedi Civil War. It is believed that Fett donned this armor during the Battle of Jaga's Cluster, where he famously eliminated the captain of a Republic frigate, an act that spread his notoriety throughout the galaxy. Following his presumed demise, the armor eventually fell into the possession of Adum Larp, a Rodian dealer specializing in arms, who listed it for purchase at a price of 15,000 credits.
