wendinu

Fourth Spear, Wendinu (四の槍・ウェンディーヌ Shi no Yari Wendīnu) is a Snake Ninpou (蛇忍法 Hebininpō) mistress of disguise who appears on Earth with her partner Furabiijo, who occasionally calls her "Wendy". Wendinu is the one who enlarges the henchmen in various ways. But Wendinu was made a Dark Spear due to her unique ability to grow into a giant super-strong berserker after amassing enough stress and rage in her. In that crazed state of mind, Wendinu destroyed an entire planet single-handedly. She is the sixth strongest spear overall in the series.
