First, Bardock charges a light-blue aura around his body as he strikes a crouching pose. Then, he shouts "I will never forgive you!" as he charges toward the opponent using the blue aura as a shield, inflicting a great amount of damage.
Bardock uses this attack on Frieza's soldiers while pursuing Frieza's spaceship. After using the Flash Spirit on a small group of soldiers, a large group proceeds to crowd Bardock, keeping him from flying to the spaceship. Bardock retaliates by using a Ki Blast to blast all the soldiers away. The Saiyan uses the "I'll Never Forgive You!" rush to knock another batch of soldiers out of his way, getting closer and closer to the spaceship while Frieza along with Dodoria and Zarbon watches on his monitor.
