In ''Countdown'', Weeks 49-47, Kyle Rayner is among those "anomalies" listed by the Monitors as being dangerous to the Universe, so he is on their list for termination. Also on the list are [[Duela Dent]], [[Donna Troy]], and [[Jason Todd]].

Rayner briefly appears in ''All-New Atom'' #15, once again carrying a Green Lantern ring (through his narration, Rayner makes it clear that he is no longer Ion, stating that he "[has] to change [his] business cards"). He now joins [[Donna Troy]], [[Jason Todd]], Bob the Monitor, and the Jokester in the ''Countdown Presents the Search for [[Atom (Ray Palmer)|Ray Palmer]]''. This story takes place after the events of the "[[Sinestro Corps War]]", though it was started while the war was still ongoing in the ''Green Lantern'' and ''Green Lantern Corps'' series. Rayner's new uniform is an amalgamation of his previous Lantern uniforms and elements of the traditional version, as well as his original mask.<ref>''Countdown'' #33 (September 2007)</ref>

When the challengers finally locate Ray Palmer (on [[Earth-51]]) Bob attacks him, revealing his acts of assistance to be a ruse.<ref>''Countdown to Final Crisis'' #18 (December 2007)</ref> Kyle escapes with Ray, who reveals that it was the deceased Earth-51 Ray Palmer who was meant to stop the great disaster, not him. The two are then attacked by [[Power Ring (DC supervillains)|Power Ring]] and evil versions of [[Booster Gold]] and [[Supergirl]].<ref>''Countdown to Final Crisis'' #16 (January 2008)</ref><ref>''Countdown to Final Crisis'' #15 (January 2008)</ref> While the battle between [[Monarch (comics)|Monarch]] and [[Superboy-Prime]] rages, the hand of the [[Source (comics)|Source]] urges the Challengers to go to [[Apokolips]]. With the help of Earth-51's Monitor, Nix Uotan, the group manages to leave before Superboy-Prime tears open Monarch's armor, obliterating that entire universe.<ref>''Countdown to Final Crisis'' #14 (January 2008)</ref><ref>''Countdown to Final Crisis'' #13 (January 2008)</ref>
