Create a full-face mask merging Japanese Oni demon features with sharp horns and fierce glowing eyes; intricate Latino sugar skull floral filigree patterns across the face; bold geometric Aztec glyph lines and warrior symbols framing the mask. The mask has an anti-hero smirk, blending menace with dark humor. Shape the mask as a diamond or shield silhouette. Use matte black base colors with blood red accents on horns and eyes, silver detailing the filigree.
