Countdown 33.
First appearance of Injustice League Unlimited.
The booking numbers in the mug shots of Dr. Light and The Prankster are references to their first appearances. Dr. Fate's, Faust's, and Ferrin Colos' appearances appear to be mistakes, as the first is off with Dream, the second is trapped in Dr. Fate's tower, and the third is dead. Oliver Queen's first line on page 9 probably was meant for Red Arrow.
Unlimited (Chapter 2) continues in Justice League of America (DC, 2006 series) #13.
