Editing Geo-Force (section)

===Justice League of America===
While sailing in his [[yacht]] off the coast of Greece, Geo-Force suddenly finds himself losing control over his powers. This sudden increase in power, which causes Geo-Force to black out, is ultimately caused by the villainous [[Deathstroke]] through as yet unrevealed means.{{issue|date=August 2023}}

Geo-Force seeks help from the newly reformed [[Justice League|Justice League of America]], becoming an unofficial member of the group. This will ultimately be revealed to be Deathstroke's overall plan, as he confronts Geo-Force to blackmail him into becoming a spy in exchange for Deathstroke's promise to remove the added powers he forced upon Geo-Force. Geo-Force informs [[Superman]], Batman, and [[Wonder Woman]] of Deathstroke's scheme and agrees to become a double agent: spying on Deathstroke for the League, while spying on the League for Deathstroke.

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.

In ''DC Universe: Last Will and Testament'', Geo-Force confronts Deathstroke in a battle. After contemplating murder, he is talked out of it by Black Lightning and Rocky Davis of the [[Challengers of the Unknown]]. He loses a lot of blood to Deathstroke in their fight, but then he sets their confrontation at the same alley and building complex where Deathstroke's second son [[Jericho (DC Comics)|Jericho]] was held after being kidnapped. Slashing his own throat in the same manner as his son was cut lets Deathstroke's guard down, allowing Brion to impale Deathstroke with his own sword through his own body. Believing he has defeated Deathstroke, while sacrificing his own life, he is surprised to wake up in the hospital. It is thought that he single-handedly took down Deathstroke, but no one knows that Geo-Force was trying to commit suicide. Geo-Force becomes the field leader of the Outsiders and is still secretly living with the shame of his actions.
