8962 Crystal King is a Power Miners set released in 2009. It includes Rex and Duke (both version 2) Minifigures.


The Crystal King has grabbing claws and crystallized teeth. His body is glowing with crystals, caused by devouring many crystals in the past, and he can fit a whole Power Miner in his mouth. His jaw is hinged and has 3 places where it locks: closed, "roaring", and opened to the maximum (about 180 degrees from the closed position). The Crystal King has surprisingly small legs compared to the rest of his body. The drill Rex is holding can revolve. It is larger than the miner, and the drill blade is made from three pieces commonly used as BIONICLE claws, eyes, or teeth. All of his crystals are green (unlike the Clutch Powers movie).


The Crystal King is the largest of all known Rock Monsters. In the "Bios" section of the Power Miners page on, the Crystal King is said to be the "undisputed ruler of the Sulfurix," likely because he shares the same colours as a Sulfurix monster. This is odd, since in the actual set description he is said to be the king of all Rock Monsters.

The Power Miners "encountered" him while mining, apparently awakening him from a very long sleep. The Crystal King is the most powerful Rock Monster, and has eaten crystals for ages. The older he gets, the more power he gains. His body is glowing with the crystals he has devoured over thousands of years. According to a comic, the Crystal King was awakened by the noise of the Titanium Command Rig's drill. Enraged, he smashes many of the Power Miners' vehicles until the Titanium Command Rig arrives. He was so powerful that he was able to lift the Titanium Command Rig off the ground during a battle. The Power Miners were able to defeat him by transforming the rig into its tower mode, knocking him off-balance. This caused the rig to fall on top of him, smashing through the cavern floor. The Crystal King apparently survived; he was seen dangling from a rock ledge in the background.
