(King's BIO HAZARD2 mythos)
The individual who became "Yāo", and the other Ten served under an Umbrella terrorist as he became involved in the artificial island. The Ten and their leader distrusted the Joker, and the soldiers used their Ki to imprison him in a web when he tried to escape. Later, they made their way out of their base camp - an abandoned train station - to the city outskirts, preparing to attack the B.H.S.T.'s compound. It was here that he infected himself with the G-Virus, as instructed. During the assault on the compound, Yāo succeeded in imprisoning Leon in a cage which appeared seemingly by magic.
