Gigalith is a blue, quadrupedal Pokémon, with various spiny, crystal-like red features jutting out of its body. Its limbs have gray joints and are topped with red crystalline features, with the two claws on each limb being similar features. It has a red eye inside each ear. Several of the crystalline features are present on its face; three below its eyes, one in the middle resembling a crest, and other crystals to the sides of its head.
Gigalith compresses energy in the core inside its body, allowing it to fire attacks powerful enough to blow away mountains. When it fires these attacks at full power, the sheer force of the blast creates multiple cracks on its body. It can also store sunlight in its orange crystals, magnify it within its body, and shoot powerful energy balls that can destroy dump trucks from its mouth, though it loses this ability at night or during rain. It lives in caves and tunnels deep underground. Gigalith is a hardy Pokémon with hefty horsepower and is a popular partner for construction workers and miners. In Galar, it works with Copperajah in construction sites and mines.
Gigalith was first seen in a Triple Battle with teammates Reuniclus and Gothitelle against Blitzle, Darmanitan, and Drilbur, during an Oha Suta episode which aired on June 27, 2010. It was not revealed in earnest until August 7, 2010.
