Golurk, along with its pre-evolution are the first and only Pokémon that have a Ground/Ghost-type combination.
Golurk is based on suits of armor that knights wore in medieval times.
The name Golurk seems to be based on the words golem and lurk.
Golurk is one of few Pokémon with higher attack than HP.
Golurk, despite being a ground type with no visible wings or form of flight, can learn Fly. It can Fly because in a Japanese comic, it showed that Golurk can act like a rocket; shooting fire out of its feet and boosting itself up. This is also proven in the first "Black and White" movie staring Victini, where a shiny Golurk uses it's lower body and hands to fly.
