Golurk is a bipedal automaton Pokémon resembling a suit of armor. It said to have been invented by ancient people to serve as a laborer. It is mainly teal in color with yellow swirls on its shoulders and hands. It has a small head compared to its body, and pale yellow eyes, one of which turns to its left at the bottom, unlike Golett's eye, which turns right. There is a crack across the chest of the armor, which is patched diagonally with a brown seal resembling a belt. It has a crystal-like formation on each shoulder, and there are large bangles on its wrists and ankles. It has a Roman armor-like "skirt" and flat feet beneath.
Despite its large size, Golurk is capable of flying by retracting its hands into its arms and its legs and feet into its body, then taking off like a rocket. If the seal on its chest is removed, its energy runs wild. This causes it to rage and fly around uncontrollably without being able to land itself. It is also capable of forming a cannon by pulling its legs into its body and standing on its hands, as seen in PokéPark 2: Wonders Beyond. Golurk was created by an ancient civilization to protect people and Pokémon.
A Golurk appeared in That's Some Spicy Island Research!, under the ownership of Hapu. Golurk was first seen assisting Hapu in a Poni Island radish field. It attacked Ash when Hapu believed he was the one who had been stealing radishes from the field, and defeated Pikachu in battle. Golurk has since made further appearances in the Sun & Moon series. Hapu commonly uses Golurk to fly around Poni Island.
AZ's Golurk appeared in The Redemption. It battled Calem and his Chesnaught, and lost. Another Golurk was seen under the ownership of a soldier, during a fantasy of a story from the past, where it was one of the many Pokémon fighting in the great war of Kalos 3,000 years previously.
Golurk and its pre-evolved form both appear to be based on golems and, considering its body structure and ability to learn Fly, giant robots. The crack and strap on its chest may be a reference to the golem in the Hebrew story The Golem of Prague.
Golurk is a combination of golem and lurk (referring to its Ghost type).
Goloog is a combination of golem and サイボーグ saibōgu (cyborg).
