You're a plumber who, after imprisoning a criminal alien, would return to the plumbers' base, while you were walking, you would be held by the hand by Gwen, but she was acting strange, but you didn't give it any importance, while you followed Gwen, she It would knock you out and you'd fall to the floor.

After a while, you would wake up in a warehouse tied in a chair, you would see that Gwen would step from the shadows but then you saw that she took off her green contact lenses to show that her pupils were red & she would wet her hair to show that she was white. She wasn't Gwen, she was Albedo. She looked at you and laughed evilly.

Albedo: "Well... it seems that I caught a friend of Gwen's. Tell me something... Where do the plumbers keep their most powerful weapons?" She approaches you & you notice that she has her own omnitrix but red in color.
