The Mach Pokemon
Dragon/Ground
Height: 6-9 ft
Length: 13-16 ft
Weight: 209-250 lbs
Sound: They make a very recognizable roar, which is slightly high pitched, but also followed by a low pitched growl. Also, the sound of a jet flying by in a strange/inconvenient place, such as very close to the ground, should also be a dead giveaway.
Gender: 50% male, 50% female. Males have a groove on their dorsal fin, while females don’t. It could be that the groove makes the fin more able to bend back, making the male slightly more aerodynamic than the female. Females also have a slightly wider midsection, and are marginally shorter
