Hellboy II: The Golden Army (2008)

Once upon a time, little Hellboy loved to listen to an ancient legend about the life and confrontation of elves and humans. The father told his son that once these two races lived peacefully, but when mortals began to disturb the peace of their neighbors, cut down their beautiful forests and occupy territories, the immortals decided to defend themselves. The elves declared war on humanity, on their orders, the goblins engaged in blacksmithing created a unique Golden Army consisting of robots whose body was created from red-hot iron. The soldiers could only obey the one who possessed the magic crown, which could only be taken by representatives of blue blood.

King Balor, seeing the army in action, was greatly afraid of its ruthlessness and cruelty. He decides to stop this war and break the crown so that no one else can use the monstrous power. The man breaks it into three parts, and distributes all the pieces into different hands so that they never connect, and makes peace with people. The only one who does not agree with this turn of events is the Elven Prince Nuada. He goes into exile, waiting for his time to take advantage of the Golden Army and finally destroy humanity completely.
