A muscular man with long dark hair, shirtless and wearing brown pants, stands in a fiery red environment, extending his right hand to generate and control a large ball of fire, which he then propels forward in a powerful blast. The scene cuts to a white silhouette of a figure against a black background, followed by a shot of a line of dark, shadowy figures with glowing eyes, viewed from behind a bald character with a blue stripe on his head.
