"The Ultimate Battle Begins!" (超決戦の火ブタ切る!! Chōkessen no Hibuta Kiru!!, lit. "Kick-Starting the Super Decisive Battle!!") is the one hundred thirteenth chapter of Dragon Ball Z and the three hundred seventh overall chapter of the Dragon Ball manga.
Standing on top of Frieza's Spaceship, Goku has detected that the battle is occurring close by. At the battle site, Frieza continues to mercilessly beat Vegeta. He throws the Saiyan into a rock formation with his tail, then complains that Vegeta is a boring opponent. Just as he is about to finish Vegeta off, Goku arrives, catching everyone's attention. Goku sees that Piccolo is there, and deduces that he was revived with the Dragon Balls. He says that he will take things from there, and Gohan and Krillin comment on his changed ki.
Goku tells Frieza to leave Vegeta alone, and Frieza feels as if he has seen Goku somewhere before. Vegeta calls Goku by his Saiyan name, and Frieza realizes that Goku resembled Bardock. Vegeta wonders if Goku is now a Super Saiyan, and Frieza promises to kill Goku. He attacks with a kick but misses, and Goku kicks him in the face. Seemingly amused, Frieza fires five simultaneous Death Beams at Goku, who manages to deflect them all with one hand. Frieza is surprised, and Vegeta tells him that Goku is indeed a Super Saiyan. He claims that Frieza is done for, and that he is glad to have lived to see a Super Saiyan. Frieza, visibly perturbed, fires his Death Beam at Vegeta through the heart, mortally wounding him.
- Although this chapter marks the very first appearance of Bardock in the manga, he also appears in the manga Dragon Ball Minus: The Departure of the Fated Child created by Akira Toriyama, which takes place before the events of the manga Dragon Ball and Jaco the Galactic Patrolman.
- Because of this, chronologically makes Bardock the very first character to appear in the manga.
