We have seen 1 named frost giant in game before in Morrowind, and there are more known in lore. http://www.uesp.net/wiki/Lore:Frost_Giant
Gargoyles have also been seen before in Daggerfall, though I don't think they were as terrifying. http://images.uesp.net/b/be/DaggerfallGargoyle.gif....Or maybe they are with that freaky grin.
We also know that there will be Hell hounds and Armored Trolls in the game. Hell Hounds were in Arena http://images.uesp.net/8/87/ArenaHellHound.gif, but their new designs may be much different, perhaps having a more undead of demonic appearance.
Also I don't know if Hell Hounds are going to be associated with vampires like the gargoyles are, but look on the upper walkway behind Harkon right here. http://www.youtube.com/watch?v=jHalNRPt_4Q&feature=player_detailpage#t=187sThere is some sort of quadruped animal walking, and It doesn't seem to me they would use normal dogs.
Anyways are there any other creatures you would like to see in Dawnguard? Preferably from preexisting lore. I really wish much more Daedra variety would be added.
