The first major boss in the Elden Ring DLC, Shadow of the Erdtree, is the Divine Beast Dancing Lion. This fearsome creature uses wind, lightning, and ice attacks, as well as its massive body to defeat players. However, it's worth noting that the boss is actually controlled by two people in a costume, similar to a traditional Chinese lion dance.
The Dancing Lion's design in Elden Ring's Shadow of the Erdtree expansion was inspired by the traditional Chinese practice of the lion dance, where two people wear a costume and mimic the movements of the big cat. One person controls the head, while the other takes charge of the body.
YouTuber BonfireVN revealed the nature of the Dancing Lion boss in Elden Ring's Shadow of the Erdtree expansion by stripping away the top layers of the boss's armor, showing that it's essentially two large dudes in a suit. The front end of the boss fires off elemental attacks and lunges at the player, while the back half follows along1. This design is inspired by the Chinese tradition of the lion dance, where two people wear a costume and mimic the movements of a lion.
