At the beginning you see Super Saiyan Vegeta taunting Android 19 and saying that he was going to send him to the scrap heap, then after that Android 19 flies at Vegeta and punches him and Vegeta takes the punch, then Android 19 hits him a few more times then stops and starts laughing like a maniac. After a bit of waiting Vegeta kicks Android 19 so hard that you can see a lump which is the same shape as Vegeta’s foot on the other side of him. Then Vegeta kicks him up into the air and teleports himself above the Android and hammers him back down to the ground which is enough to create a massive crater in the ground that Gohan, Piccolo, Tien and Krillin had to avoid, then Vegeta goes down into the hole too. He starts taunting the Android even more but then Android 19 jumps up and grabs both of Vegeta’s arms and goes on about the fact that he’s not going to let go, then Vegeta jumps up and smashes Android 19 in the face with his feet and keeps on pushing with them. After a while Vegeta cries out that you should never give up and pushes his feet so hard that both of Android 19’s hands come off, and he goes flying into a wall! Then Vegeta observes the energy absorbing devices on the Androids hands and throws them on the ground, and Android 19 is so scared that he scurries up the pit and starts running away from Vegeta, when Vegeta goes up too, Android 20 shouts for Vegeta to stop battling but Vegeta says that he’s saying that because the two Androids are losing the battle, Vegeta then chases after Android 19. After a little clip of Yamcha still carrying Goku back to his house it returns to the battle scene where Vegeta is talking to Android 19 from above, he then gets really mad and fires a Big Bang attack at Android 19 and blows him to pieces!
You then see Bulma, Yajirobe and Baby Trunks in the hover car flying towards the battle scene and they all start worrying about the massive explosion up ahead, Yajirobe then freaks out and Trunks starts crying so Bulma starts arguing with Yajirobe and then they fly off. Next, you see Vegeta flying down towards Android 20 and asks him why he thinks he’s so strong when he was made by the same person as Android 19, only Android 20 says that he is different and much more powerful, he then flies away really fast and Vegeta gets really mad about it and starts to give chase. Piccolo, Gohan, Tien and Krillin decide to go and search for Android 20 themselves too and so they split up to find him, Vegeta gets really mad and powers up a massive energy blast and Krillin freaks out because he thinks that it is going to hit everyone else too but out of no where, Android 20 comes out and absorbs the whole blast, and runs off. Vegeta gets REALLY angry now and carries on looking and so is everyone else as you see clips of them all searching for the Android, Android 20 then says that he needs more energy if he is going to defeat Vegeta and so is going to sneakily absorb energy from Piccolo, Tien, Krillin and Gohan instead because he knows that Vegeta won’t make the same mistake as last time, the episode now ends here.
