In Multiversity, one of the parallels world is protected by another team with the same name and is composed by amalgamated versions of members of the Justice League.
When Superman and Batman tried to return home from their brief and maddening adventure in The Nanoverse they ended up stranded apparentely on a alternate world instead. In this world teams as The Justice League and the Teen Titans did not exist in a traditional sense. Rather the people and the places they knew had been merged into one. Here the main superheroes were the Justice Titans (an amalgamated alternate reality version of both the Teen Titans and the Justice League) with Night Lantern as their leader.

When the spell of the witches was broken and Dr. Destiny defeated this illusory world ceased to exist.
