Goku is later joined by android 18, whose look reminds 17 of each his personal and Dr. Myuu’s true nature, contributing to the ends of both Myuu, who was killed by 17’s Shocking Death Ball, and Super 17 himself. Dr. Gero and fallen colleague Dr. Myuu brainwash Android 17 telepathically via Hell Fighter 17, a Machine Mutant version of himself created by the 2 scientists in Hell with the design of merging with him into the final word killing machine.
After attacking Trunks and earlier than merging, 17 asks Android 18 to join him, a gesture which she mindlessly obeys until a fatal attack on Krillin brings 18 back to reality, inflicting her to attack her brother. Seeing what she has accomplished, he then targets Marron so he can acquire full management of 18, however 18 defends her from 17’s Photon Flash, leaving her in a crucial situation.
However a few of the cells (implied to be those of Kid Buu as his clones share the unique’s personality) went out of control causing Android 21 to develop cravings to turn individuals into meals to devour and take up their power like Cell and Majin Buu. This triggered 21 to develop an evil cut up persona which is vying for control of Android 21’s physique.
16 states they planned to make use of the soul link system developed by Dr. Gero to suppress the evil 21. Android 21 recreated 16 as a result of him being designed after her human son and would have lived peacefully with him had it not been for her cravings and rising evil persona.
Pan’s ploy to have Gero deliver 17 to a halt is ruined when Dr. Myuu reveals his programming placed him in full management of the tremendous android, and so Super 17 kills Dr. Gero, for the second time. Piccolo and Dende create a gateway between Hell and Earth, permitting Goku to flee and confront Super 17, before another Z Fighters may be killed.
How was Super 17 created?
He does not possess a visible nose, and has six spots of moxibustion burns on his forehead, a reference to the practice of Shaolin monks. Toriyama once stated, seemingly humorously, that Krillin’s lack of a nose is because he has a “physical idiosyncrasy” that allows him to breathe through the pores of his skin.
