Killowat (incorrectly spelled as "Kilowatt" throughout) is accidentally pulled through a time portal that leaves him stranded in the present, and the Titans must find a way to return him to the future. Raven and Herald open an inter-dimensional portal and the Titans have to find which alternate world to send him to. One reality is ruled by the Teen Tyrants, their evil alternate counterparts, and opposed by the Brotherhood of Justice, the good alternate counterparts to the Brotherhood of Evil.
