Golurk is an enormous bipedal golem-like automaton with ethereal ghostly powers. Its bulky, heavily armored body appears to be composed of a teal-bluish rocky material; it also appears to be wearing knight-like armor. It has a small head with a spike-like formation at the tip and two yellow eyes (one of which is L-shaped). Its relatively small head is attached to a great round torso. It has a large glowing fissure across its chest, which is stitched closed by a brown band. It has a cylindrical tasset-like formation just beneath its torso, and thick, heavy legs with brown bands encircling its ankles just above its massive feet. Its arms are long, thick and powerfully-built; its shoulders are round with spines protruding from either side, and it has massive five-fingered hands with brown bands encircling its wrists. It has diamond shaped features with glowing yellow swirls on the front of its hands, and identical swirled patterns on its shoulders.
Golurk is extremely powerful; it is in fact so powerful that it must have a seal on its chest to keep its internal energy from leaking out, causing it to lose control. Golurk are known as ancient protectors of people and Pokémon. It can Fly, using rocket-like propulsion, to move at Mach speeds.
Golurk is the evolved form of Golett as of level 43.
Golurk and its pre-evolution are the first Pokémon that have a Ground/Ghost-type combination.
Golurk is one of few Pokémon with higher attack than HP.
Golurk, despite being a Ground type Pokémon with no visible wings or form of flight, can learn Fly. It can fly because it uses its lower body and hands as propulsors.
Golurk looks a lot like The Iron Giant from the movie of the same name, and flies in the same manner.
Golurk along with its pre-evolution are the only non-Legendary Ground-type Pokémon from Unova that are not owned by any main character in the anime.
Golurk is based on a ghostly golem warrior or automaton. Its design is based on suits of armor that knights wore in medieval times. Golurk may be based on the Prauge golem, as both are golems and both have some sort of seal on their chests.
Golurk's name seems to be based on the words "golem" and "lurk".
