Create a blocky, Roblox-style version of Nyx-7 with a lean, athletic build. The robotic augmentations on the arms, legs, and parts of the face should be made using simple, geometric shapes to give a blocky, low-poly appearance. The nanotech armor should look sleek and reflective, with a color-shifting effect to blend into the environment. Nyx-7's neon blue eyes should glow faintly, adding a cyberpunk touch. The design must emphasizing stealth and agility in a simple, blocky style.
