Four humanoid turtle warriors, each wearing different colored masks

Four humanoid turtle warriors, each wearing different colored masks (red, blue, orange, and purple), stand in powerful and dynamic fighting stances. One wields two sharp katanas, another holds a long wooden staff, a third grips dual nunchakus, and the last one has twin sai daggers. Their muscles are tense and their stances grounded, as if preparing for an epic battle. The scene is set in a gritty urban alley at night, lit by glowing neon signs and dim streetlights, with rain-slicked pavement reflecting the light. Their skin is realistic, with detailed reptilian textures and strong, battle-worn bodies. Their armor combines leather and tactical gear, emphasizing their role as fierce urban warriors. The group is positioned in a triangular formation, ready to strike, with intense expressions that show their readiness for combat.
