Fun fact: The Gaur Plain stage in Super Smash Bros. for Wii U and 3DS isn't actually set in the Gaur Plain area of Bionis' Leg. I think it might actually be set on or near Viliera Hill, which is north of (or above, depending on your perspective) Gaur Plain. Also, you never actually fight Metal Face on the Bionis' Leg, meaning that Xord would have been a more appropriate boss for that stage.
