FROM TEA AND SECOND BREAKFAST IN THE SHIRE TO FACING DOWN MORGOTH'S EVIL.
GIF INFO: Spotlight on what, personally, I find to think is the coolest-looking, most terrifying Orc adversary in the entire "The Lord of the Rings: The Fellowship of the Ring" (2001) motion picture, the unidentified, more than likely, female goblin warrior encountered in the mines of Moria. Creature makeup effects/design by Wēta Workshop.
PIC #2: In second place, my second favorite Orc creature design was the unidentified Orc Taskmaster, who ultimately oversaw the Isengard Orcs working in the caverns, breeding Goblin-men and forging weapons for the Great Enemy's army of Uruk-hai warriors.
