is, in fact, Geo-Force's sister. Terra is afraid of finding out the results, fearful that she might, in fact, be a villainous traitor. When the test results come back positive, Brion lies to Terra, telling her that the results are negative. Around this time, as part of the Day of Judgement incident, a portal to hell threatens to swallow the country of Markovia. A small team of Outsiders, including the newer Terra, Katana, and the original Halo, are on hand to help combat it. Geo-Force and Terra become kidnap victims of a strange cult run by a man with mind-control powers. They are rescued by the super-team called the "Birds of Prey". Geo-Force briefly appears in 52 #35, assisting Metropolis citizens injured in a mass-murder caused by Lex Luthor. He later is a part of the army of heroes gathered by the Justice Society at the end of 52 to battle Black Adam who, in his global killing spree after the death of his wife and brother-in-law, has murdered Terra II. Before the battle, Geo-Force tells Beast Boy not to blame himself for Terra II's death.

Geo-Force seeks help from the newly reformed Justice League of America, becoming an unofficial member of the group.

The scheme falls apart when Lex Luthor organizes a new incarnation of the Injustice League and captures the Justice League. While a prisoner, Geo-Force is brutally tortured alongside Red Tornado at the hands of Gorilla Grodd. While recovering from his injuries, Geo-Force is "traded" to Batman's latest incarnation of The Outsiders, much to Geo-Force's dismay and, ultimately, acceptance.
