What is the Tolkien creature beginning with letter o?

Answer 1

That would be an ogre (although ogres are not specifically an invention of Tolkien). Actually, orc would be a better answer. Tolkien's fiction included both ogres and orcs, but the orcs were his invention, unlike the ogres.

Answer 2

The Tolkien creature beginning with the letter "O" is an "Orc." Orcs are fictional humanoid creatures in J.R.R. Tolkien's Middle-earth legendarium, serving as soldiers and minions of dark lords like Sauron. They are often depicted as fierce, brutal warriors.

Answer 3

orc
