So I was browsing WowHead yesterday, seeing if they had anything new up. And somehow I got to looking at all of the devilsaurs.
I linked the Wowhead page in the picture if you want to see it, but there's no actual description.
To quote one of the comments: "It's a T-rex. Mounted on a flying rocket shark with lasers. With a guitar playing undead on top."
I don't know who came up with it, but I love it.
