Who else except?

Off of the top of my head, the following teen heroes wear/have worn hoods:
 * Phantasm
 * Raven
 * Red Hood (Kingdom Come Lian Harper)
 * Speedy (Mia Dearden)
 * Static

But that doesn't mean it's one of them: Phil Bourassa, Dusty Abell and Jerome Moore can reinvent other heroes as hood-wearing.
