YOU ARE A UNIQUE
and more powerful than you know. Since you do not have a dimensional twin you cannot be externally controlled by the Reciprocity Effect.
You may also be able to cross over from one reality to another. What this means is that you are in the position of changing multiple realities at once. Most Uniques just want to live normal lives and may never realize that they live in multiple realities, but the dark forces of E.S.C.H.E.R. Corp and The Shadows of Mercy are forcibly recruiting people like you, who can phase their atomic structure. They need powerful Uniques to activate an interdimensional bridge. This bridge will allow them to have complete control of both worlds.
