TMNT dragon AU 🐉

Nickname: Leo and Leonardo. Weapon: Twin ninjas. Splinter, who serves as their adoptive father and sensei. Due to his unwavering dedication to ninjutsu, and partly because he requested it, Splinter chose Leonardo to be the leader of the Turtles. Leo is an emerald green ninja warrior. His eyes have sapphire blue irises with black pupils, but like his brothers, when they are shown fighting or being stealthy, they disappear, leaving their eyes white. He wears a royal blue bandana-mask (although he wears a black bandana in his emo and rebellious guise). He is the most skilled fighter; his green skin is slightly darker than the others. His ninja equipment includes brown knee and elbow pads, and beige bandages wrapped around his wrists, ankles, and fingers. He is the most serious, mature, and focused of the team. As the designated leader of the group, Leonardo is very enthusiastic about his role. He is also a big fan. Leonardo is a science fiction fan. His favorite series is "Space Heroes," and his favorite character in the series is Captain Ryan. Leonardo has a habit of memorizing Captain Ryan's best lines from the series and sometimes repeating them during battle. Leonardo is so caught up in Space Heroes that he relies on Ryan's character traits rather than his own intuition, which often causes his brothers (especially Raph) to question his leadership. However, there are occasional moments where he can be as childish as his brothers, such as teasing Donnie about one of his inventions failing. He often tries to comfort his brothers when they are scared or upset, especially Michelangelo. Overall, he is a helpful, adventurous, brave, responsible, hardworking, protective, honorable, respectful, and enthusiastic ninjutsu prodigy with a "can-do" attitude. He is the most serious, disciplined, composed, mature, spiritual, stoic, level-headed, calm, courageous, and focused member of the team.

1. Wing Bud and Dorsal Opening Point of origin: In the side view, the wings do not grow directly from the outer surface of the shell, but from the deep muscle mass of the back, right between the shoulder blades and the inner part where the dorsal armor joins.
   Internal pressure: The bone structure of the new limbs (similar to an elongated upper limb with extended phalanges) begins to form beneath the armor. As it expands, it exerts continuous pressure from the inside out.
   Opening of the shell: The force exerted eventually fractures the bonds between the carapace and the posterior skin. As the appendages advance, the skin gives way, allowing the winged limbs to unfurl along the sides of the torso.
2. Bone and Muscle Reorganization
   Bone expansion: To support a dragon's wingspan, the spine and ribcage undergo accelerated lengthening. The bones creak and readjust as the vertebrae spread apart and the shoulders broaden to support the new pair of limbs.
   Muscle stretching: The dorsal and pectoral muscles divide and reconfigure into thicker, more extended bundles. New muscle connections are formed that extend toward the wing cartilages, allowing movement of the membranes.
3. Skin Development and Texture
   Skin formation: Between the long, articulated fingers of the winged structure, the skin stretches until it becomes thin but tough, tightening as the wing is fully extended to the sides.
   Skin Transition: The smooth skin of the original profile gives way to a more rigid texture, with protective plates and scales developing along the spine and shoulders, integrating the structure of the old shell with the new reptilian physiognomy. They went from being simple turtles to being Turtle Dragons, guardians of a force they barely understand.
