Walkthrough
Chapter 8 begins on the World of Kais, with Elder Kai explaining the situation to Supreme Kai. They cannot do a thing about Android 21, except keep watch and hope that the Z-Fighters can defeat her. After this scene, you return to the Map to face more Clone Battles and Regular Battles - as well as Clone Kid Buu Battle - none of which will have have any implication on the main story. You will end up having to face another Boss Battle against more clones. After defeating them, the next scene will begin, showing Android 21 turning Nappa into a treat and then eating him. After she does, she calls out Cell, who she could sense was around all along. She has become stronger by consuming a number of fighters, and then she does the exact same thing to Cell.
Once you have seen that, you will again return to the Map and have to defeat more Clone Battles and Regular Battles, leading to yet another Boss Battles against even more clones. After doing all of this in a relatively quick fashion, you will see Android 21 next turn the entire Ginyu Force into cupcakes and hen dine on them. After Android 21 has had her next meal, Frieza will appear and quickly learn the sad fate of Cell and the other infamous villains like himself. Frieza will try killing Android 21, but he isn't strong enough now that Android 21 has gained the Energy of all the fighters she has consumed. Android 21 then turns Frieza into her next snack, before deciding to ultimately go after the Z-Fighters next. After completing the next wave of Clone Battles on the Map, including one against Clone Kid Buu, Chapter 9 will begin.
