Úvanimor

The Úvanimor were monsters of various kinds created by Melko (Morgoth). They appear in several of JRR Tolkien's earliest tales included in The Book of Lost Tales and the The Lost Road & Other Writings.

Background
While in the North; Morgoth (Melko) built his strength and gathered his demonbroods about him, the Balrogs. There he made the Úvanimor, monsters of divers kinds and shapes bred from the earth; they were monsters, giants, ogres and wicked dwarves (Nauglath) and these were the agents of Melko (but Orcs were not made until he had looked upon the elves).

They feared the feared the sinews of Tulkas arm and his iron-clad fists, when he had cause for wrath. Also Túvo protected Men and Elves from them and from ‘evil fays’, and of Orcs besides.
