A character with a topknot performs a firebending move, generating a large fireball against a backdrop with the Chinese character for fire, then the scene cuts to a silhouette of a character in a fighting stance with the character for "good" behind them, followed by a young boy with dark hair and a determined expression generating a fireball in a dimly lit room, then a close-up of a bald boy with a distinctive head tattoo concentrating intensely, and finally a female character with brown hair and a red outfit in a dynamic pose with fire effects around her.
