Mistress Splinter

While retaining the martial arts expertise and calm demeanor of Master Splinter, this version would have a more feminine silhouette. Her face would be similarly gentle and wise, with a slightly less pronounced jawline and more delicate features. Hair would likely be black and styled in a manner that is both sophisticated and practical, similar to the original Splinter but with a more feminine touch. She might wear traditional martial arts attire, modified for a more feminine silhouette. This could involve flowing robes, a kimono-like outfit, or even a more modern, tailored suit. The color palette would likely be muted, reflecting Splinter's character, but with a touch of feminine elegance, perhaps with subtle embroidery or decorative elements.
