Bullies

The Batbros are all in high school together. That's right, Damian, Tim, Jason, and Dick are all in the same school together and it's fun. They're all too smart to be in their grades but they can't let the government figure out their secret vigilante side job. School and heroism is hard but that's why you have friends.
(Ages and grades go like this: Dick: 18 and Senior, Jason: 17 Junior, Tim: 16 Sophomore, Damian: 14 Freshmen.)
