Chibi Fighter Sprite Sheet

Generate a 4x4 sprite sheet of a chibi anime character on a transparent background. The character is a young boy with spiky black hair featuring blue highlights, wearing a dark navy sleeveless martial arts gi with orange trim and white wristbands. Each cell in the grid must depict a distinct frame of an action sequence: Row 1 shows idle poses and a punch wind-up; Row 2 displays a dash attack followed by a heavy punch impact with orange energy effects; Row 3 features a high kick with blue motion trails and a spinning kick; Row 4 contains crouching defense and standing guard poses. Ensure consistent proportions across all frames for animation looping.
