Clone snowtroopers under Commander Mag were deployed on the icy world of Orto Plutonia, where they were tasked with testing subzero gear such as the Freeco bike. After the outpost was wiped out by the Talz, another clone cold assault task force from the 501st led by Captain Rex was sent to investigate, accompanied by Jedi Generals Anakin Skywalker and Obi-Wan Kenobi.
