History
Escher was a member of the UK branch of Department X (otherwise known as the X-Tremists) and took part in trying to prevent the X-Tracts, a movement of anti-establishment rebels, from inciting a love fest on the streets of London.
This version of Escher disappeared when the Age of X-Man collapsed. It is unknown as yet if there is a version of him in Marvel’s standard 616 continuity, like there is of so many characters originating from the Age of X-Man.
Powers
Escher is invisible. This might be an ability he has no control over as he wraps himself in a specially made uniform to be seen
