Gigalith is a mainly blue-colored, quadruped Pokémon, with various spiny, crystal-like red features jutting out of its body. The joints of its limbs are gray-colored, and its limbs are topped with red crystal-like features, with the two claws on each limb being similar features. It now has a red eye inside each ear. Several of the crystalline features are present on Gigalith's face; three being below its eyes, one, in the middle, forming some kind of crest, and the other crystals to the sides of its head.
