Walkthrough:
Chapter 7 begins with Android 17, Android 18 and the good version of Android 21 finding the evil Android 21 in one of the Red Ribbon Labs. The evil Android 21 has found the remote that Controls the machine creating the Energy-suppressing waves. The good Android 21 tells the others how her evil persona activated the machine that Dr. Gero created long ago, hoping to paralyze all of the people of earth in order to devour them all to gain their energy. It came as a risk though, as the waves also have an effect on both versions of Android 21. The evil persona thought she would be strong enough to overcome the waves, but she wasn't after she had eventually activated the machine. This was how the good version of Android 21 was able to regain control of her body and resurface to her consciousness, having tried to hold back her evil persona as long as she could afterwards.
After this has been shared with Android 17 and Android 18, the evil Android 21 will eat the remote, thinking it will causes her more trouble than good if she kept it whole. However, after doing this, she realizes that all of the waves have stopped being sent across the globe. She doesn't really care though, as she will look to finally finish off the remaining Androids. Just then, Krillin and Goku will suddenly appear. Krillin will share how they already know everything that is going on, and the Goku will quickly Instant Transmission to grab some Senzu Beans for the others.
After Goku returns, it appears as though he will have a showdown with the evil Android 21 right then and there. Before the fight is about to happen, however, the evil Android 21 will back off, saying she will save the best fight for last. She will then use Instant Transmission to flee. Once she has left, Krillin will share how they learned about the entire from Dendy, who has been observing how things had unfolded from the Lookout. Goku will mention how the evil Android 21 had learned the Instant Transmission Technique after seeing it done just once, much like Majin Buu had. Krillin will then add how she turns people into candy before eating them in order to absorb their Energy, also like Majin Buu had done.
After Android 18 wonders if some of the same cells that make up Majin Buu were indeed used when Dr. Gero created Android 21, Krillin and Goku will ultimately agree to help them stop the evil Android 21. The good Android 21 will thank them dearly, and then the group will decide to round up more fighters before proceeding further. After this, you will have your next set of Clone Battles, Ending with yet another Clone Boss Battle. Once all of that has been taken care of, Chapter 8 will begin.
