Dio Lazuli

A purple-skinned character with a star-shaped gem on their forehead fires a beam from a purple cannon-like arm at a blue, crystalline character, causing the beam to splash and freeze the blue character's arm. The two characters then run across a rocky, icy landscape before the purple character delivers a punch to the blue character's face, sending water droplets flying. The scene takes place in a cavernous, icy environment with jagged rock formations and a dark, starry sky.
