(Showcase '93 #4, 5) - Geo-Force flew Denise Howard to Markovia so they could spend some quality time together, and she was deeply impressed with his nobility. Geo-Force had to deal with a mysterious electric fire at the Earth-Fusion Lab before bringing Denise back to his castle. He showed her ceremonial armor, and told her that Queen Ilona was expecting an heir. he'd imagined he'd one day be king, but was happy to step aside, because his first duty was to serve Queen and country. They soon discovered the culprits behind the fire, the Untouchables, villains who could turn intangible. One of their number, Clyde Barrows, was dying because he'd been permanently rendered intangible, and they needed Markovian tech to fix his condition. Geo-Force promised to render his assistance if they agreed to surrender to his authorities, because he wasn't about to hand over scientific equipment to criminals. They balked, and turned him intangible so he could see what their friend was going through. Geo-Force almost suffocated because he couldn't breathe air before using a plus-gravity field to make himself more solid. Untouchable Bonnie panicked and put a gun to Denise's head. Geo-Force still refused to deal with terrorists, and negotiations got tense before Denise reminded them that if they didn't start working together Clyde as a dead man. Geo-Force made a royal pledge to cure Clyde, and he would allow them to go free afterwards. They went to Dr. Kneidel's lab, where she hooked up a generator to Geo-Force so he could extend his plus-gravity field to Clyde Barrow. Untouchable John Dillinger doubted the royal word and started destroying equipment, making Geo-Force's generator overload so they'd have a chance to flee. Geo-Force released the resulting explosion in the atmosphere, and retuned to earth to apprehend the Untouchables, who realized they screwed up in not trusting his word.

Geo-Force served as a member of the Thunderfront when they attacked the JSA, the only heroes not under the Humanite’s control. The JSA used a device that disrupted the braincaps Humanite used to control the Thunderfront, leaving them unconscious but freed from Humanite’s mental domination. The JSA later defeated Humanite.

Black Adam was a god with nothing left to lose, and each punch he threw was intended to kill. His savagery was winning the day until Martian Manhunter reappeared and flooded his brain with his own loss, the death of the entire Martian species. Black Adam was distracted long enough for Captain Marvel to hurl a Shazam bolt at him. Theo Adam was powerless, and left with amnesia. He staggered away unnoticed from the end of WWIII.

(Justice League of America II #4-7) - Geo-Force was on the HMY Viktor when it was bombed. Geo-Force crawled from the wreckage, and put in a call to Black Lightning.

His memories started going, and he found himself dressing in his old Geo-Force costume. Geo-Force met with Black Lightning in Gotham City, and told him he suspected that he was the one that sunk his own ship because his powers were out of control, and he'd seemingly acquired Terra's powers.

(Tales of the Sinestro Corps: Superman-Prime #1) - An army of Earth's heroes, including Geo-Force and the Outsiders, appeared to take Superboy-Prime down during the Sinestro Corps invasion of Earth. The heroes focused on wrecking his armor, because after a year on Oa, and away from a yellow sun his Kryptonian body still wasn't at full strength, and his armor collected sunlight. Superboy bragged that once the sun rose on Earth he'd be at full power. Superboy was battered by Wonder Girl and Wonder Woman, who blamed him for Superboy's death, as well as Supergirl and Power Girl, who blamed him for the death of the Superman of Earth-2. As the fight went against him, Superboy broke down in tears. He tried to wipe them away, saying that it was impossible for boys to cry, and then whining that no one ever thanked him for sacrificing his Earth to save the multiverse. The battle lasted until dawn, and he flew into the sunrise. As he achieved full power he declared himself the one, true Superman. The Guardians arrived with Sodam Yat, the new Ion, and pitted him against Superboy-Prime.

(Batman & The Outsiders Special #1, Outsiders IV #15) - Feeling the call of the Earth Geo-Force spent weeks digging a hole before burying himself for three days. His servant dug him out to announce the presence of Alfred Pennyworth, who'd come to recruit him for the new Outsiders. Alfred assembled the Outsiders and explained Batman's vision, that they all represented aspects of his personality, and that there would always be a 'Batman' outside Gotham. He required them to go off the grid, cutting off contact with everyone in their lives and becoming true Outsiders. They'd be a frontline group, constantly in the line-of-fire and constantly risking their lives. Geo-Force rankled at a butler giving orders, but Alfred reminded him that he'd served in MI-6 and was Batman's aide for many years. Alfred dismissed them to consider his offer, and Geo-Force brought Katana to the alley where he fought Deathstroke. He admitted that he had no one to miss in Markovia aside from his servant Sergai, and as he relived his encounter with Deathstroke, he asked Katana if she'd do anything to defeat someone trying to steal her soul. She said yes, because souls are all we have, and they kissed. They rejoined the Outsiders the next day, as did all of Alfred's other recruits. Alfred told them they'd be confronting the Outsiders greatest enemy, who'd been behind their conflicts with such former antagonists as Bad Samaritan, the Duke of Oil, and the Force of July, even though they'd never met face-to-face.
