Phantom Zone
In the miniseries "52" the Phantom Zone is ingested by Mister Mind while he is mutating into a giant insect form. Once full-grown, Mind regurgitates it in an attempt to destroy Booster Gold and Rip Hunter, but the attack is deflected by Supernova, who returns the Phantom Zone to its proper dimensional plane. Supernova is able to control the Zone as his supersuit's powers are based upon Phantom Zone projector technology stolen by Rip Hunter.
