The Trollocs are introduced in the very first episode of Amazon's "The Wheel of Time," and interrupt the festival of Bel Tine to begin massacring the innocent townsfolk, though we don't get a whole lot of information about them in these early scenes.
They appear as huge, shaggy humanoids with animalistic features, hoofed feet, and enormous horns on their heads. As with humans, no two Trollocs are exactly alike; some may swap their fur for feathers, or their animal fangs for beaks, though each one is between eight to 10 feet tall.
They are capable of crude speech and have a sadistic sense of humor, and while they are far less intelligent than humans, they are brutal in battle and known to eat the people they kill. Their animalistic nature makes them very dangerous in large groups, but easy to defeat one-on-one.
The Trollocs are essentially the main strength in the army of the Dark One, and as Amazon's series continues we're sure to see plenty of them along the way. On the other hand, perhaps our heroes won't have as much trouble with them as they do in these early episodes.
