Kaiden claims to be a survivor of the Raccoon City outbreak but this has been brought into question due to a lack of birth certificate. He claims that the information is simply lost but it is unknown. If he had been alive at the time he would have been 13 years during the outbreak. Either way he made his way into the B.S.A.A. at the age of sixteen after showing a great deal of knowledge of viral diseases even advancing the B.S.A.A.’s antidote for the T-Virus. How he managed that at such a young age is unknown but they ignored it and allowed him into the B.S.A.A.. Since then he has become a field agent and aided in containing several outbreaks.
