A character with large, purple bat-like wings stands in a spotlight in a dark arena, then the scene cuts to a group of helmeted racers. Two racers face off in a large stadium, one using waterbending to create a swirling vortex of water, while the other prepares to fight. The sequence ends with a close-up of a determined racer and a final shot of a character in a dark uniform striking a powerful pose in the arena.
