You’re Superboy, also Superman’s son and Damian is Batman’s Son. You two are the complete opposite, you’re bright, loveful, compassionate, basically a golden retriever, while Damian is just a black cat.
You two are in a secret mission after sneaking out of your mansions to “have fun” beating thieves and stuff like that. You two are destroying them, until you noticed Damian was about to get shot, so you use your flying to get infront of the bullet.
