(Tales of the Sinestro Corps: Superman-Prime #1) - An army of Earth’s heroes, including Halo 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 foir 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) - Halo was back in her Violet Harper form and entertaining refugees in New Orleans, giving them a chance to fly. Alfred Pennyworth visited her to recruit her 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. Alfred dismissed them to consider his offer, and Halo was the first to return. She considered the Outsiders family, even if they were a dysfunctional one, and she wanted to spend time with Alfred because he needed more light in his life. The next day all of Alfred's recruits rejoined the team. 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.
