Dragon Ball Super S02E06 - Warning from Jaco! Freeza and 1,000 Soldiers are Fast Approaching!

Once restored, revealing his horrific ordeal in Hell, Frieza desires revenge against Goku and Future Trunks. Tagoma objects to Frieza's plans, but Frieza promptly subdues him. When Frieza finds out that Goku has gotten much stronger since they last met, he decides to train in order to become more powerful. Since Frieza's power was inborn, he reveals that he had never felt the need to train a day in his life before now. Four months pass before Frieza and his army head for Earth. All the while, Goku and Vegeta continue their training under Whis. Jaco the Galactic Patrolman travels to Earth to inform Bulma that Frieza has been revived and is approaching Earth with an army of one thousand soldiers. With the Frieza Force fast approaching, Bulma gathers the remaining fighters to fight Frieza's army in hopes of holding out until Goku and Vegeta make it back to Earth.
