In the comic 图书 Flash (Barry Allen) dies and Wally takes over. In YJ, Flash is still alive, so wally hasn't taken over. Also, in Justice League Unlimited they're probably going 由 the comic books, YJ doesn't go 由 the comic books.
Young Justice is completely different from the comics and JLU. (JLU Is better in my opinion, because it is almost exactly like the comics, with a tad bit of 动画片 flair and director imagination)
