In front of the planet, a shadowy, dark entity looms ominously, shaped with undefined edges and glowing eyes. The dark entity's body flows like liquid smoke into the space beyond. The bottom features silhouettes of five youthful figures—resembling the Teen Titans—gazing upward towards the entity, their stances a mix of awe, determination, and unease.
