In the beginning of the "Brightest Day" storyline, Alan lies in the arms of Obsidian, convulsing and writhing as a green light pours from his body. His body possessed, Alan flies off with his JSA teammates in hot pursuit, eventually led the team to Germany. The JSA meet up with Batman's new Justice League and find that Jade, who had been staying on Oa since her resurrection, has returned to Earth inside a green meteor, later revealed to be the legendary Starheart that gave Alan his powers. Sebastian Faust tells the two teams that the Starheart has been gradually taking control of people on Earth for quite some time. Now that it is on Earth, it is growing more powerful and driving metahumans all over the world insane. Jade states that the Starheart captured her in space and purposely brought her to Earth to find Alan and that it is her fault that her father is now in danger. Just then, Alan awakens and his costume transforms into a suit of armor identical to the one he wears in "Kingdom Come", and he then tells the assembled heroes that he intends on destroying the world.
