Schott Key No.2 is a small doll-like Stand with triangle shaped marks on its head, that is kept contained within the younger A. Phex Brother's soccer ball. It is hidden at all times behind the zipper in the soccer ball.
Toxic Gas: Schott Key No.2 is an automatic Stand that constantly releases a toxic gas, the strength of which is not shown in full. The gas has burned Josuke's skin on contact and made it difficult for him to breathe, suggesting that at full potency it could kill a person. Because Schott Key No.2 is automatic, it is kept within a soccer ball with a zipper on it, and the gas is only released when the zipper is undone. Schott Key No.2 can be used in combination with Schottkey No.1, as the elder A. Phex Brother can touch the zipper on the soccer ball with his left hand to spread Schott Key No.2's toxic gas with his right hand, but the power could possibly backfire on both of them.
