 Should it kill someone without a Factor's "assistance", usually by accident, a Machina has been known to resuscitate and heal the person by injecting their D-S.O.I.L nanobots into them, which in turn makes the person a Factor.This is case for Factor Reiji Moritsugu.In the case of Kouichi Hayase, then-Linebarrel pilot Emi Kizaki begged Linebarrel to heal him, which turned him into a Factor, at the expense of making Emi a less desirable Factor to Linebarrel ("It" does not want Emi to fight).
