Quox is a dragon from the other side of the world, and a descendant of the original dragon.
Although Quox is young, by dragon standards, he is very large. At the time of his encounter with Betsy Bobbin and company he was a mere three thousand fifty-five years old. His body is a lovely sky-blue color and thickly set with glittering silver scales, each as big as a serving tray. His head and face are not especially ugly for a dragon, but his eyes are so large that it takes a long time to wink. Whenever he smiles he shows sharp, terrible teeth. His nostrils are large and wide, and his breath smells of brimstone. His voice is a little gruff, but not unpleasant. An electric light is attached to the end of his tail.
Quox had insulted the original dragon, calling him senile, and for this Tititi-Hoochoo the Great Jinjin made him his Instrument of Vengeance against the Nome King. He strapped seats to the dragon's back and had him carry Betsy Bobbin, Private Files, Hank the Mule, Polychrome, the Shaggy Man, Tik-Tok, Queen Ann Soforth and her army back through the Hollow Tube. Quox used the enchanted ribbon around his neck to cause the Nome King to forget his magic, and he deposed the Metal Monarch exiling him from his kingdom with eggs, which are lethal to Nomes. When the conquest of the Nome King was finished, Quox returned home through the Hollow Tube. (Tik-Tok of Oz)
One eventually attacks the Emerald City and the tunnel it dug is a key to finding the Silver Fortress during The Good the Wicked and the Silver. Unfortunately when the Witch finds the Silver slippers this allows her to control it, until Dorothy removes the protective spell on the silver shoes which allowed its wearer to control the quox.
