Kamen Rider Siren from Kamen Rider Dragon Knight is captured in Figma SP-026 with a dynamic, battle-ready silhouette. The figure features a sleek, armored suit that blends dragon motifs with rider armor, finished in a rich palette of deep purple, cobalt blue, and metallic silver. Each plate is sculpted with layered edges to convey movement, while translucent energy accents hint at Siren's sonic powers. The head is designed with a compact helmet and crest, and the figure includes multiple interchangeable hands and a stand for dramatic poses. Articulation is engineered for wide poseability, allowing action stances, mid-air kicks, and weapon-ready poses while preserving signature stylistic details from the series.

In the Dragon Knight universe, Siren is a formidable Rider whose power centers on sound and resonance. Trained to convert shock waves into precise, blade-like strikes, she moves with a dancer's grace that hides the ferocity of her attacks. Siren's arc involves a fragile alliance with the Dragon Knight and a personal quest to restore balance between rival factions that harness dragon energy. Her calls disrupt enemies, while her blade taps into the dragon's heartbeat, creating ripples of energy across the battlefield. Across battles and betrayals, Siren's resolve grows as she learns to trust allies, harness her voice as a weapon, and carve her place among the growing legend of the Dragon Knight team.
