Can be tamed.
|Wowhead:||Wild Onyx Serpent|
Located in Mount Neverest, Kun-Lai Summit. The Wild Onyx Serpent circles Mount Neverest in Kun-Lai. It can be difficult to reach but you can just get in range of it if you find the right outcropping to stand on. At max level, use an item level 1 weapon (can be bought from a weapon vendor), remove your armor, and perhaps even kill yourself and take resurrection sickness to pull the serpent without killing it.
