Iron Golem

Iron Golems are a type of golems constructed out of metal.

Appearance
Iron Golems, at least the ones in the Great Tomb of Nazarick, are three meters tall. The golems were shaped like armored warriors.

Abilities
So far the ones in Nazarick are made from rare metals, thus they were stronger than regular golems made by the Supreme Beings.

Trivia

 * Two of these golems are explicitly named in the Web Novel.
 * They appear in the Light Novel, acting as guards to the Grand Library Ashurbanipal.
