User blog comment:Oknight/End of Young Justice 2 spoiler/@comment-3465526-20110322173344

Okay, having re-consulted RT's history, (Lord! What a horrible, horrible mess) I learned RT had a similar role in the original comic book Young Justice (I've never read it), which provides a more simple meta-explanation of what he's doing there. (I understand that a cross between Teen Titans and YJ was the original sort-of genesis of this project)

Of course in RT's history he has been used as a villian weapon to attack the JLA several times...
