The intent is to be comprehensive of predator-named chess pieces. Still on
Wolves and Foxes, http://www.chessvariants.org/large.dir/evilhorde.html,
there in Fantasy Grand are two. Werewolf moves forward as Knight, and
promotee Wolf Rider combines King and Knight. Wolf has also been Carreran Champion Rook plus Knight and Fox Carreran Centaur: http://www.chessvariants.org/large.dir/wolf.html. The so many languages, it's as if Arno von Wilpert were reaching out in 1940 to prevent WWII.
Charles Gilman implemented the Stiles' Fox and Wolf double-bend riders here: http://www.chessvariants.org/index/msdisplay.php?itemid=MS4linepiecefusi. There he explains Rook plus Wolf is SheWolf, and Rook plus Fox Vixen.
No Giraffes of course. But the ground is not shaky at all to call Gryphon predator and will include (all-spellings the one griffin, griffon etc.)
