Episode 19 - Resurrection 'F'

Synopsis: With their power dwindling due to the absence of their leader, the remnants of Frieza's army are led by an alien named Sorbet, who decides to revive their master. He then sets off to Earth with one other minion, Tagoma, where they convince Pilaf, Mai, and Shu, who have collected the Dragon Balls to let them summon Shenlong instead. As Shenlong is unable to fully revive Frieza, he brings him back to life in pieces, which his minions reassemble using their advanced technology over the following two months. Once restored, Frieza plans revenge against Goku and Future Trunks, and then kills Tagoma when he objects to this, and learns that Goku has gotten much stronger, to the point of defeating Majin Boo and thus, he decides he too needs to become more powerful.
