|"No Hope for Atomic Knights" from Final Crisis #4 (DC, 2008) by Grant Morrison, JG Jones, Carlos Pacheco and Jesus Merino|
Like most crossover events, it did launch a bunch of other things. Barry Allen came back. Batman was sent into the past. That kind of thing. Spin-offs didn't actually continue after their initial mini, like Japan's own brand of Justice League the Super Young Team, or nipple arsonist the Human Flame. Even the wonderful moment when Aquaman was seen alive and well was ignored and Geoff Johns resurrected him on his own terms in Blackest Night. What a mess.
