Q: How do you rebel?
Red Hood: Kill to stop the killing, unite the underworld and make your own rules, keep your father and brothers at arm's length, protect Gotham, the city your father Batman protects, and keep the city's legend alive.
Rebel Knight: While his father King Arthur is away on a Roman campaign, master and make full use of the time-honored tradition of "backstabbing" (a future skill), take control of his father's city of Camelot, and face his father in a one-for-one showdown at Camlann, bringing the legend to a close.
-- Batman, already worried about his rebellious second son, one day discovers that a self-proclaimed good guy named Prydwen has teamed up with Jason. Well, he can't exactly be called a good guy, but he's much more normal than Jason's other associates.
Then summer passes, and Prydwen transforms into Mordred, one of the legendary Knights of the Round Table and the most famous rebellious son in European history, Pendragon, making his entrance!
Mordred: Let's set aside the whole taking-off-your-helmet thing. How is any of this real rebellion?
Jason: For once, I don't know how to argue with that.
The true rebel's background is from Prototype.
The fake rebel's background is from a crossover I thought was okay.
