Shok Choka was a male Yuuzhan Vong warrior. He was the leader of a boarding party aboard a space station in the Yag'Dhul system. He challenged Corran Horn to a duel, but Anakin Solo took Corran's place. During the fight Shok Choka swept Anakin's legs from under him. He tried to punch him but overcommitted. In the split second he had to decide whether to roll forward or get back up, Anakin responded by cutting his head off.
Tall for a Yuuzhan Vong, Choka's personal scars included three large chevrons on each ear, and a scar that ran from his chin, through his lips, up to his skull.
