Dragon Ball Super S02E10 - Clash! Freeza vs. Son Goku! This is the Fruit of My Training!

The battle between Goku and Frieza begins. They fight on even ground, with neither one able to inflict significant damage to the other. Frieza resorts to attacking Krillin and Bulma. Goku tries to save them and is caught off guard when Frieza lands several blows on him. Eventually lashing out at Goku, Vegeta intervenes out of impatience for the fighters' constant rambling and holding back their full power. Goku takes Vegeta's request into account and convinces Frieza to power up to his maximum. When Frieza calls out to Goku to show his full power, Goku transforms on his own into a new version of a Super Saiyan God.
