New people come to comics all of the time, and may know of one Robin, Dick Grayson. Unless they’ve seen The New Batman Adventures or Young Justice, then they may know of Tim Drake, or the animated movie adaptations, where they first heard of Jason Todd or even Carrie. With an event centered around Robins (this being modern DC of course they’re fighting like Marvel characters), Comic Book Resources gives a quick history of the Boy (and Girl) Wonders.
