Black Adam. In the 2006 One Year Later storyline, Owen finds himself placed in the metahuman prison known as Iron Heights. There he finds himself being the cellmate of Black Lightning, who was arrested for a murder that Deathstroke the Terminator committed. It is soon discovered that the other inmates have learned of Black Lightning's identity and are planning to murder him. The Outsiders become aware of this and attempt to break Pierce out of jail. Unfortunately it goes terribly wrong. As they escape, Black Lightning asks that they take Owen with them, which they grudgingly agree. As they escape, the Outsiders' jet, the Pequod, is shot down, and while the team escapes, the world believes them dead. Because of this event and the Freedom of Power Treaty, the team now works covertly. Most of the current Outsiders were believed dead until a botched mission revealed their presence to the world. His history as a Rogue has been exploited several times by team leader Nightwing from torturing dictators to taking down a cloned Jay Garrick. However, it is revealed that his desire to join the Outsiders comes from his desire for a family. Nightwing allowed him to join his team partially because Arsenal felt he would be worthy, and because Owen has been striving to find a family since the death of his father and the outbreak of the Rogue War. Owen searched out the current Robin because of their connection, where their fathers killed one another. While Robin originally believed Owen was searching for him to finish the fight his father started, in Robin #152, Owen revealed that he wished to make amends with the younger hero, and has offered his assistance to help Robin destroy a bomb created by the Joker. The two later spend the following night spreading out old hideouts of several villains. Afterward, Robin gained a bit of civil respect for Boomerang despite what their fathers did to one another. Boomerang attempted to shake hands with Robin, but Robin refused the gesture feeling unready to make that step. At some point during his tenure with the Outsiders, Captain Cold approached the mercenary Deathstroke with an offer concerning Owen. In exchange for kidnapping Deathstroke's daughter Rose (who had betrayed her father and joined the Teen Titans) and delivering her to her father, Deathstroke would track down the Outsiders and turn Owen over to the Rogues.
