Ironfist was a human male Mandalorian mercenary active during the Cold War.
It was rumored that he worked for the Sith Empire for a long time and, in particular, for Grand Moff Kilran himself - and he was never captured, defeated or even driven back.
He and his men were hired to capture the bridge of Republic transport the Esseles so that Kilran could gain custody of Ambassador Vyn Asara, whom the Sith Empire classed a terrorist. While an Imperial boarding party led by Lieutenant Isric distracted a group of Republic operatives, Ironfist's Mandalorian forces seized the bridge of the Esseles. Upon realizing their mistake, the operatives stormed the bridge and freed the command crew, killing Ironfist in the process.
