This card is based on the planet Saturn, the sixth planet in the Solar System.
This card's name is derived from "big", an adjective used to describe something of large size, referencing how Saturn is the second-biggest planet in the Solar System.
This monster's design features a spherical main body and a ring around it, referencing how Saturn is known for having many rings orbiting around the planet.
This monster's ring is also likely a reference to "Ring of Destruction", which also features an effect that inflicts damage equal to this card's ATK.
