- ―Sixtat as he takes on the final challenge
On Serenno, Sixtat was invited to participate in the Box challenge, alongside ten other contestants, where the five winners would take part in Dooku's plot to kidnap Supreme Chancellor Palpatine. Following the guidance of Obi-Wan Kenobi, he survived up to the final challenge, where Morallo Eval informed the survivors that the next challenge involved hitting moving targets with a sniper rifle. Confident in his abilities, Sixtat decided to take on the challenge first. He managed to hit two of the targets, however when he missed one target the floor beneath him fell, and he fell into the fire below.
