Jagger, a Mandalorian belonging to Clan Ordo, existed during the violent era of the Cold War between the Galactic Republic and the Sith Empire. He accompanied Corridan Ordo and other clan members, including his close companion Torian Cadera, on a hunt to Dxun, the beast-ridden moon of Onderon. While the Mandalorians primarily hunted bomas and maalraas, Jagger successfully killed a zakkeg during the expedition. Subsequently, Cadera jokingly called Jagger a "lucky jare," a Mandalorian expression for someone who is nearly suicidally daring.
Jagger made his initial appearance within Star Wars canon through the massively multiplayer online game, Star Wars: The Old Republic. This game was developed by BioWare and launched on December 20, 2011.
