Explanations: (1) Greninja uses fast, physical attacks similar to fox's fighting style. (2) Fox's Arwing is a fast flying object made of a hard material (Sound familiar?). (3) Fox uses powerful kicking attacks in Smash Bros., much like Blazekin. (4) A fast, cool looking canine Pokemon fits Fox perfectly. (5) Flygon can fly (obviously), and the dome/screen things on its eyes remind me of a pilot's goggles. (6) Every character as awesome as Fox deserves a cool legendary, and this one happens to be a fox Pokemon (Zoarark would be more Wolf's style).
