"Performs a spinning uppercut that launches an opponent into the air."
— Dragon Ball Xenoverse 2 Tutorial description
To use the attack, Dodoria simply uppercuts the opponent, knocking them away, while the force of the attack is so great it causes a small whirlwind around the point of the impact, dealing a huge amount of damage.
Dodoria used this attack to land the decisive blow on Tora while executing Bardock's Planet Elite Force in Dragon Ball Z: Bardock - The Father of Goku. After Frieza decided to destroy Planet Vegeta, he ordered Team Dodoria to hunt and kill Bardock's team on Planet Meat. Tora was dealt with last, and while Dodoria held him up, he explained to him Frieza's plans as he used Critical Upper to land the finishing blow on him. Tora eventually dying from his injuries in Bardock's arms.
