A male Human Mandalorian named Jarg became a member of the Neo-Crusaders in the time of the Mandalorian Wars. Once the war concluded, Jarg, along with Reeza, became part of Sherruk's band of outlaws. As a pilot, he rode an XT-model bike. Eventually, the group made their way to Dantooine, where they began to terrorize and extort the people who lived there.
In 3956 BBY, Juhani, in a fit of rage, killed both Jarg and Reeza, while Revan killed all of the other Mandalorians who were present on Dantooine.
