LEGO Power Miners

Boulderax is a Rock Monster character featured in the LEGO Power Miners theme, introduced in 2009. He is a large and imposing creature made of brown and dark brown rocks, with visible orange crystals embedded within his body. These crystals are the source of the Rock Monsters' power.

Unlike some Rock Monsters like Meltrax, Boulderax does not appear to have any specialized weapons or functions built into his design. He relies on his size and brute strength to combat the Power Miners and steal their energy crystals. He represents a common and formidable enemy within the series.

Boulderax is portrayed as a destructive force, eager to seize the crystals and wreak havoc on the underground mining operations of the Power Miners. He's a recurring antagonist in the sets and associated media, serving as a constant obstacle for the miners to overcome.
