Zerras anatomy

I did this so u could understand Zerra better.
Sorry for the differant color paper but i did it on a bigger scale and it did fit in the scanner.
So Zerra is a tipe of mutan like most of the pepole on the planete (in my storry).
Zerra is a mix of 4 types of dragons (Montain dragon, sea serpant, forest dragon and desert dragon), a cheetah and a human.
So feral parts:-Cat claws
-Cat ears
dragon parts:-Teeth
-Hydrogen (she hasen't got the flight bladers other dragons have because her wings are big enought to carry her weight)
-Wings (which u can't see.)
human parts:-Body structure.

1) Two acide glands.
2) Lungs and hydrogen sacs.Can breath hydrogen out of mouth or nose ( Warning!acide+ hydrogen=Fire!
3)Finger, nail, cat like Claw.
4)Claw come out of her toas.

so their u go, its crazy i know, but i thaugth it would be cool. warning!beware of the dragon temper!:D
