At the funeral of the Flash, Bart Allen, the Monitor tells Jason and Donna that the former Atom, Ray Palmer, is alive and lost somewhere in the Nanoverse, and that locating him is key to surviving the coming crisis. Donna, Jason and the Monitor (nicknamed "Bob" by Jason), meet with current Atom Ryan Choi in Ivy Town to recruit him in the search for Ray Palmer. Searching for him within the microscopic "Nanoverse", they are captured by Queen Belthera, and are later rescued by Kyle Rayner before Ryan Choi is abducted back into Ivy Town. Kyle informs the group that they will have to tour the Multiverse to find Ray Palmer, and they encounter the Authority on Earth-50, a Soviet Superman on Earth-30, and the Crime Society on Earth-3. As they leave Earth-3, they are unexpectedly joined by the Jokester (the Joker's heroic counterpart and father of Duela), passing through Earth-15 and later Earth-8, where Lord Havok and the Extremists capture them before an invasion by Monarch and his newest recruits, the Crime Society gives Jason the opportunity to feign a betrayal, allowing their eventual escape.
