During the "Brightest Day" prologue, Digger is seen locked in his Iron Heights cell. Digger is visited by Tim Drake whose father Harkness murdered. Tim tells him if he tries to escape, he will hunt him down personally. He is later given a message from Captain Cold saying that if he wants to be one of the Rogues again, he has to prove it by escaping from prison on his own. After being beaten by guards, Digger is being seen to in the medical bay, when he suddenly finds himself able to create boomerangs out of energy that explode on contact. While not understanding where this new power came from, Digger uses it to escape Iron Heights and attacks the Renegades while they are trying to apprehend the Flash for murdering Mirror Monarch. Shortly after, he finds himself confronting a wounded Flash.
