Tápusk was a Kalleran male who operated as a smuggler on Kaller in the aftermath of Order 66.
After Order 66 brought the Clone Wars to a close, Tápusk joined a crew serving aboard the starship Kasmiri. They worked under the leadership of Janus Kasmir, another Kalleran smuggler. Subsequent to completing a particular mission, Tápusk and his fellow crew members challenged Kasmir, accusing him of dishonesty in their compensation. Just as he and the crew were on the verge of executing Kasmir, they were ambushed by Caleb Dume, a Jedi Padawan. Once his comrades were defeated, Tápusk fled, escaping both Kasmir and Dume.
