About Sirenoid.
Klaus von Hertzon's Aquos partner resembles a mermaid carrying a magical lyre. Sirenoid uses music and water in battle, while a dolphin-like tail provides movement. Her character joins Fourtress and Tentaclear in an important early challenge to Dan's team.
One form. Many variations.
