Batman (real name Bruce Wayne) is a crime-fighter from Gotham City, and a founding member of the Justice League. When Nightwing was still Robin, Batman was his mentor, and is now a mentor to a new Robin, as well as Batgirl. He was also responsible for assigning missions to the Team.
Batman has a strict by the book personality. He rarely smiles and keeps a level head in nearly every situation. Despite this, he is not above showing kindness, as he raised Robin like his son.
His role and personality as a mentor to the Team shows him to be a very stern general and taskmaster, yet surprisingly, understanding authority figure. He is quick to issue orders and expects them to be followed with no questions asked, but he does listen and at times even accept the opinions of younger heroes. His natural commanding presence and intimidating personality commands respect from the Team, but he rarely, if ever, abuses or lords his authority unfairly over them. In fact, even when the Team makes mistakes on their missions, he makes certain to still praise them on what they did right, as well as educate them on what they didn't.
Batman also seems to take a personal interest in the young heroes beyond their work as covert agents for theJustice League. Aside from Robin, he's taken an interest in trying to help Superboy and Superman connect, suggesting to Clark to try and help the newly born clone and play the role of a father figure. He also helped set up Artemis for her superhero career and, via the Wayne Foundation, got her a scholarship to get enrolled in Gotham Academy. He is incredibly serious and assertive, traits often displayed when he takes command on missions, and when with the Team.
He is particularly fatherly towards Dick, setting aside time once to play basketball with him when sensing that he was jealous of Aqualad, who got attention from Batman as the leader of the Team.
Batman is a tall Caucasian male with a dark and imposing figure, short black hair, and dark brown eyes. He wears a dark gray costume with the symbol of a bat spread over the chest, black trunks, gloves (with fins on the outer side), boots and a black cape with a unique pattern at the end. Batman also wears a black cowl designed with bat ears at all times to hide his identity.
He also wears a yellow utility belt to complete his Batsuit. As Bruce Wayne he normally wears a formal black suit with a grayish-blue tie.
