The doublemove ferz (single capture, without Null move) is the same piece as the Free Padwar in JETAN. The Free Padwar movement diagram comes from a loose interpretation of the rules of JETAN, as given by Edgar Rice Burroughs. The Jester is the same piece, with a special initial move added. I have called the Free Padwar a 'War Elephant' in three of my chess variants.
