Donnie

Build. Donnie is the tallest and slimmest of the brothers, with slightly elongated proportions. He looks less like a brute and more like a nimble and agile ninja. Skin. Olive green with cool undertones—slightly lighter than Raf's, and not as rich as Leo's. The face. Elongated features, large eyes (reddish-brown in this version), and a signature detail—a noticeable gap between the front teeth. Signature color. The purple mask with long "tails" is Donnie's main signature color. Equipment: Brown elbow and knee pads, beige wrist, finger, and ankle wraps, diagonal torso straps. The shell. Yellow-brown, segmented, with dark lines. In this version, it looks a little more technical due to the fastenings and straps. Weapon: A bo staff, which in the series can transform into a naginata (spear-sword). The team's "brains." Donnie is knowledgeable in technology, programming, physics, and chemistry. He assembles gadgets, vehicles, and communication systems from literally any scrap material. For him, technology is a way to protect his family. A perfectionist and an anxious analyst, he calculates and endlessly double-checks everything. If something breaks (especially his own invention), he becomes extremely upset and can lose his temper. Socially awkward but empathetic, Donnie often speaks in overly complex terms, spouting jargon and failing to notice that his brothers don't understand him. At the same time, he's sensitive to others' emotions: if someone is upset, Donnie will try to help, even if he doesn't know the right words. An internal conflict between science and tradition. He prefers precise calculations to "trusting his instincts." Kind and non-confrontational, he rarely gets truly angry, and when he does raise his voice, it's usually due to stress or when someone handles his equipment carelessly. Combat skills. Master of the bo staff and ninjutsu: combines acrobatics, weapons use, and tactical thinking. Engineer and inventor. Tactical thinking. Speaks in too much detail. Keeps records and diagrams. Nervous in chaos.
