A colossal reptilian creature, its body a dark, mottled grey, resembling volcanic rock hardened into dense, jagged plates. Smooth, metallic silver armor gleams around its forearms, shoulders, and head, reminiscent of Aggron's plating, while its large, powerful tail is segmented with Tyranitar's rough, green-tinged scales. Its red, piercing eyes glow from within a heavily armored, horned skull, conveying an unyielding, aggressive stance.
