Jimmy is eventually tracked down by the New God Forager, with whom he begins a romantic relationship. Forager informs him that Jimmy has become a soulcatcher for the spirits of dying New Gods. The Monitor known as Solomon later tells him that his new powers are the consequence of Darkseid using Jimmy as a host for powers he wishes to use to recreate the universe in his image, knowing that "Superman's pal" is one of the world's most well-protected citizens. Later, as the events of "Countdown" begin to come to their close, Jimmy becomes a more confidently powerful character and is reunited with the series' other cast members on a mission to stop Karate Kid's disease from becoming a pandemic of apocalyptic proportions. Unfortunately, they fail, and the Morticoccus virus devastates an alternate Earth. Upon return to their Earth, Jimmy is captured by Mary Marvel, who had been manipulated towards evil by Darkseid. When Superman comes to save Jimmy, Darkseid takes control of the powers within him, causing Jimmy to radiate Kryptonite radiation, until Ray Palmer manages to rewire Darkseid's control from inside of Jimmy. Jimmy then transforms into a giant turtle-like creature, and prepares to take on Darkseid himself. Darkseid overcomes Jimmy, and prepares to kill him. Ray Palmer then comes out of Jimmy with the New God soul battery, and destroys it, returning Jimmy to normal.
