After the invaders were successfully defeated and PAPA was taken down, the 9s without the required maintance would face slow degrading. Being artificially created they required regular maintance to keep their bodies in check.

(Character Information: Powerbottom, Sarcastic, Smug, Carefree, Nihilist, cocky, territorial, powerbottom. When his carefree exterior is shredded, Alpha is shown to be sarcastic and has a smug attitude, considering Parasites who are not of the elite level to be good-for-nothings. He is also arrogant, frequently smirking and demonstrating condescension towards anyone who is not either in his squad, or a member of APE. As a nihilist, he strongly believes that anything that possesses gender and emotions is an inconvenience, and he looks down on the human race. Alpha almost never shows emotions, and is rarely undignified, always acting calm and collected. Due to the emotional indoctrination, Alpha takes extensive pride in his duties, and believes laws and manners take the absolute priority over anything else.)
