NPC – Dos-Ryga
It’s already quite obvious that pet battles are a throwback to Pokemon, but this is the first Battle Pet that I’ve seen that seems to be named after a Pokemon. Dos-Ryga is a water type Fable battle pet, found in Kun-Lai summit (added in Patch 5.2).
Dos-Ryga is an angram of Gyrados. Gyrados is a dual type water/flying pokemon (information from Bulbapedia) with a dragon like appearance. Gyrados evolves from Magikarp, which more closely resembles Dos-Ryga.
Interestingly, Magikarp have an extremely strong immune system and can live in polluted waters. Perhaps that is why you find Dos-Ryga next to the Sha polluted water in Kun-Lai. Gyrados however are destructive – it appears Dos-Ryga is somewhere in-between the two.
