Golden Cube

Golden Cube was the most powerful Cube, one of The Cube Queen's personal cube and Storyline Entity in Fortnite: Battle Royale. The Golden Cube first made its appearance in Chapter 2: Season 7, during the Operation: Sky Fire event.

Description
The Golden Cubes are identical to the Corruption Cubes, albiet golden in colour. The Golden Cube acts as a catalyst for Cube reproduction, allowing for more cubes to be spawned in once it "activates/awakens" other Corruption Cubes. During The End event, Cube Queen used the Golden Cube at the top of The Pyramid to gather all corruption cube energy and use them to open a golden rift to the Last Reality.

Operation: Sky Fire

 * Right before The Mothership explodes, The Looper and others witness all the cubes inside a room on The Mothership activate. On the far side of the room, players could just barely make out the Golden Cube as she let out a loud monstrous sound. In the ending cutscene, players could very faintly see said cube in its beginning location on the map.

Chapter 2: Season 8

 * Throughout the entire chapter, this cube moves around more than any other, going around and "Activating" other cubes, in order to produce more cubes. It moves every hour until arriving at The Aftermath. A timestamp list is below:

The End (Chapter 2)
The Island has flipped and The Golden Cube and most likely dissolved. Its current whereabouts are unknown along with The Cube Queen
