This monster is an upgraded version of "Des Feral Imp"; both have the same Attribute, Type, Level/Rank, and their Japanese names include "gremlin". "Des Feral Imp" itself is an upgraded version of "Feral Imp".
This card's Japanese name is a portmanteau of the words "king" and "gremlin". It could also be interpreted as a portmanteau of "kin" (the Japanese word for gold or a synonym for "children") and "gremlin", since he is surrounded by tiny, gold-colored gremlins, a significant portion of his body is the color gold, and there are pieces of raw gold in the background.
This monster's design is based on the gremlins from the 1984 horror-comedy film Gremlins.
This card's effect may also references the movie, as when a gremlin gets wet, they multiply; this card's effect allows the controller to obtain a Reptile-Type monster from their Deck when Xyz Material is detached from it.
This monster appears in the artwork of "Xyz Trip".
