Art style: Pixar-like 3D.
Donatello "Don 'Brain'", shown full-length from head to feet, standing upright — a tall lean mutant turtle humanoid with smooth olive-green leathery skin and a slim, wiry build. He wears a purple bandana mask knotted around his eyes, its long tails hanging behind. His expression is calm, sharp and analytical, with alert intelligent eyes and a faint knowing smirk. He wears a slightly rumpled grey hoodie under an open dark tech-vest with many zip pockets, dark cargo trousers, and worn grey sneakers on his three-toed feet. Slung across his chest is a laptop bag; a coiled headset hangs at his neck and a smartphone with a wiretap dongle sits in one green three-fingered hand. He stands in a dim cluttered back-room lined with monitors, tangled cables and stacked cash, weight relaxed, one hand adjusting an earpiece.
