The Watchtower is the one from the first and second seasons of Justice League- which was destroyed in the final episode, just before Unlimited aired. Also Wonder Woman remembers and makes mention of Jonah Hex, Bat Lash and El Diablo, whom she supposedly had forgotten after the event s of 'Once and Future Thing'. Though she took part in that 'adventure', she had disappeared back into the present and retained no memory of what happened. It is unknown whether Green Lantern or Batman informed her of said events, but it is doubtful they would have, so as not to risk damaging the timeline.

Jonah Hex, Bat Lash, El Diablo and Wonder Woman all appear in JLU season three ender, 'The Once and Future Thing.'

What appears to be Green Lantern Alan Scott's battery is in the Watchtower Trophy Room.

This was an okay read, but nothing stellar. We are treated yet again to a time travel story. But of course, how else can the so-called 'Justice Rangers' be utilized. The art also leaves something to be desired. While they do Elongated Man and the Vigilante beautifully, Wonder Woman and Jud seem forced and hard into model.

- the appearance of Vigilante's ancestor, Jud Saunders, closely modeled after Batman Beyond's Terry McGinnis.

- the return of the 'Justice Rangers'.
