Mob: Ironhide Devilsaur
Location: Roaming Un'goro crater
Level: Must be 69 to tame him. (Exotic)
Tame details: The tame itself isn't very hard, but Devilsaurs are infamous for being everywhere when you don't want to see them and nowhere when you do. It can take hours to find a devilsaur, let alone of the right color.
There's also a mob with his same skin in Netherstorm, level 71, by the name of (I think) Tyrannus.
Appearance:

Model: A nice, if rather low poly, model. The feet and head are especially nice, with well done toes and teeth. He's pretty blocky, though, and it only shows more on a scaled down, pet-sized Devilsaur.
Skin: I've never been super fond of this one. It doesn't seem black enough, nor blue enough. There are a lot of fake shines on his scales which make him seem more 3d than he is, which is nice, and I like the yellowish skin showing between his scales. He has striking blue eyes, which make his stripes look very dull in comparison. His stomach is tan-orange, which looks pretty odd next to his otherwise cold colors… A grey belly would perhaps fit it better.
Animations:

Disappointingly, he only has one idle, but he makes up for it by it being awesome. He roars, with a neat sound and everything. Other then that, he just waves his tail from side to side constantly.
His run animation is still built for his larger size. When he's huge, it would be terrifying to look back and see some massive beast running after you, shaking the ground, head lowered to the ground so he can stare at you intently. As he's now small, though, it looks rather silly.
The same goes for his attacks, which are designed for a beast trying to smash bug-like players. He stomps, bites, and head butts, but he does so to attack things on the ground… It seems like he's trying to knock someone over now that he's small.
His swim, at least, makes sense in any size. He looks adorable, too. It's an exaggerated raptor paddle, so adorable!
Combat:
Devilsaurs are excellent DPS pets, though their Exotic ability is exceedingly situation-based. If you're not fighting a mob that heals itself, it's useless. His other ability, a wolf-esque 5% crit roar, is very nice and useful in most groups. As a Ferocity pet, he doesn't make the best tank, but you have to be BM to use him so he's automatically a bit stronger.
I already have two devilsaurs, so this one will not stay.
Another? :->
