Shok Choka was a Yuuzhan Vong warrior of the male gender. He commanded a boarding group on a space station located within the Yag'Dhul system. Corran Horn was challenged to a duel by him, but Anakin Solo stepped in to fight in Corran's stead. During their combat, Shok Choka managed to sweep Anakin's feet out from under him. He then attempted a punch but extended too far. In the brief moment he had to choose between rolling onward or standing back up, Anakin reacted by decapitating him. Choka stood taller than most Yuuzhan Vong, and his individual scars consisted of three sizable chevrons on both of his ears, along with a scar extending from his chin, through his lips, and up to his skull.
