A sleek, feral humanoid Skyrider, fused with Hesperornis, has a muscular, streamlined body of black and steel-blue plumage. A ferocious face with an elongated beak, sharp predatory teeth, and crimson eyes, set in a serrated grin. Jagged armored fins replace wings. Dark chrome armor, jagged and serrated like aquatic scales, glows with turquoise runes, offering a hard, scaly tactile quality. It wields dual hooked obsidian scythes, curved like lightning, charged with glowing storm energy, in an aggressive, lunging stance.
