4) Robin (Damian Wayne)
Before Superman became a dad, writer Grant Morrison went and gave the Dark Knight a son back in 2006 (inspired by a non-canon story from 1987). The result of a tryst between Bruce Wayne and Talia al Ghul, Damian Wayne is every bit as volatile and unpleasant a 13 year old boy as you would expect from the progeny of a moody vigilante and an assassin.
Genetically perfect and grown in an artificial womb, Damian has a massive superiority complex and an ego the size of Gotham City. When he’s first placed in his father’s care, Damian is little more than a sociopath – he attempts to kill Robin to get close to his dad – but under Batman’s influence he grows into a hero and forms a close if fraught relationship with Bruce.
Nowadays, Damian has mellowed into a loveable brat. He might still think he’s the best superhero in the world and belittle his friends – mostly Jon and his teammates in the Teen Titans – but we know his heart’s in the right place.
