"Leaps up and fires a Ki Wave downward."
First, Zarbon puts his right hand upward and charges an orange energy sphere. He then puts his hand forward and fires an energy wave at the opponent, inflicting a high amount of damage.
Zarbon uses this attack to kill an old Namekian while he, Dodoria and Frieza are interrogating for the whereabouts of the Namekian Dragon Balls at Moori's village. After Zarbon killed an elder with a kick to the neck as an example of the Galactic Frieza Army's power, a second elder, enraged, moves to attack Zarbon. Zarbon tosses up one of the Dragon Balls he is holding, dodges the old Namekian's Energy Cannon (killing one of his soldiers instead), and kills him with the Shooting Star Arrow. Zarbon then gracefully returns to Frieza's side and brilliantly catches the Dragon Ball he threw into the sky.
Appearances in games
Shooting Star Arrow was named in the Budokai Tenkaichi series, where it is one of Zarbon's Blast 2 attacks. The attack also appears in the Raging Blast series, Dragon Ball Z: Ultimate Tenkaichi, and Dragon Ball: Zenkai Battle Royale. In all those video games, the technique is an energy barrage wave. Zarbon also uses the technique when summoned in Dragon Ball Z: Supersonic Warriors 2, where it is an energy wave.
This attack reappears in Dragon Ball: Xenoverse 2 under the name Gorgeous Shot, as one of Zarbon's Super Skills. It can also be learned by the Future Warrior (Xenoverse 2) by completing Student Quest: Lesson 1 of Zarbon's Training. Unlike most video games, Gorgeous Shot is depicted as an Energy Wave in Xenoverse 2.
Interestingly, it is called Shooting Piledriver in the Plot description of Lesson 1 of Zarbon's Training despite the Skill being listed as Gorgeous Shot in the mission's Basic Rewards section.
