The basic program of FOXALIVE was designed by Naomi Hunter, which she then entrusted to Sunny in 2014, during the short time she was on board the Nomad. Sunny completed the program with an enhanced variation of the worm cluster created by Emma Emmerich, the code of which she found within the Nomad's supercomputer, Gaudi. According to Otacon, it worked by triggering apoptosis in GW's "cells."
