Hugo is wrong. It is true that any piece moving to threaten an Orphan is automatically threatened by it, but what if the piece is also protected by an ally? Then if the Orphan captures it the Orphan itself can be captured as it has no time to capture the next piece. For example, there is a Black Orphan on a4 and a White Rook moves to d4, where a Bishop on b2 protects it. If the Orphan captures the Rook, the Bishop can capture the Orphan.
Is this a record for the time taken to reply to a comment? My excuse is that I have only recently become interested in pieces which imitate.
