(Titans II #36, Titans Annual II #1) - Atom Ray Palmer investigated the death of Atom Ryan Choi and learned that Deathstroke and his Titans were responsible. Atom contacted Batman, Starman and the Justice League, and they confronted the Titans, demanding justice. Deathstroke showed the Justice League that his plane was equipped with a nuclear self-destruct system, and he’d rather destroy himself and them than surrender. Deathstroke also told Arsenal he knew the League would never allow him to die, because they still considered him one of their own. This exact situation was the only reason Deathstroke allowed Arsenal to join his team. The League backed off temporarily, and allowed the Titans to fly off. The League confronted the Titans again in Kahndaq, where the villains had enlisted the support of Kahndaq’s ruler Osiris. Batman tried to get Arsenal to side with the League, but he refused, telling him that heroes never won when it counted. Tatooed Man rejoined the team, just as Deathstroke knew he would, and gave Slade the opportunity to stab Supergirl with a kryptonite sword created for him by Lex Luthor. The battle ravaged Kahndaq, and Isis had enough. She demonstrated her godlike powers, and banished the League from her country. She sent Osiris and the Titans off, telling her brother that he’d proved he was unfit to rule.

(Titans II #38) - Mikaal, the Justice League of America and the rest of the superhero community attended the funeral of Atom Ryan Choi
