Nazgûl are humans, they're the kings that took the 9 rings given to the them by Sauron.
The flying 'drake' things didn't have names:
"The great shadow descended like a falling cloud. And behold! it was a winged creature: if bird, then greater than all other birds, and it was naked, and neither quill nor feather did it bear, and its vast pinions were as webs of hide between horned fingers; and it stank. A creature of an older world maybe it was, whose kind, lingering in forgotten mountains cold beneath the Moon, outstayed their day, and in hideous eyrie bred this last untimely brood, apt to evil. And the Dark Lord took it, and nursed it with fell meats, until it grew beyond the measure of all things that fly; and he gave it to his servant to be his steed. Down, down it came, and then, folding its fingered webs, it gave a croadking cry, and settled upon the body of Snowmane, digging in its claws, stooping its long naked neck.
Upon it sat a shape, black-mantled, huge and threatening. A crown of steel he bore, but between rim and robe naught was there to see, save only a deadly gleam of eyes: the Lord of the Nazgûl."
BTW: Smoke, they're called 'mûmakil', not 'mammalkill'
Now if you want controversy...
Why didn't Frodo just hitch a ride on an Eagle to begin with, all the way to mordor, toss the ring in, and fly back? They completely pwnt the Luftwaffe of Mordor, Sarumon couldn't stop them, what the hell!
BTW: IMO the ROTK movie was infinately better then the book. I can't say the same about the other two, but I never liked ROTK book... Frankly, Tolkien is the most horrid descriptor or battles ever
He goes off on these ass-long tangents about which way the flags are blowing...
