Isn\'t it the Zero Virus? And I think one of the main reasons that all of the other Reploids get infected by this virus and X doesn\'t is that Dr. Light made him to his own perfection. The original reploid copied from x (excluding Zero) were based on the designes of X. However, some of the text was illegible. That\'s why they were so vunerable. Dr. Cain missed them out and just ignored them.
BTW, if that\'s the case, how come the games describe X as the most powerful reploid?
