Justice League of America, Vol. 1

The Flash of Earth-Two helps Earth-One's Flash defeat a group of terrorists before heading to the JLA satellite. Before they can reach it, they're attacked by the Thunderbolt who leaves Earth-One's Flash mortally wounded. Aboard the satellite, the annual get-together of the Justice League and Justice Society is in full swing when it, too, is attacked by the Thunderbolt. Several members of the League are injured before Black Canary manages to banish it just as the two Flashes arrive, one carrying the other. After ensuring the injured members are safely being treated, the heroes attempt to contact the other members of the League only to find they too have been struck down. To compound matters, several super villains are attacking mystical locations at the same time. As the Society members leave to tackle the villains, Black Canary and Starman track the Thunderbolt back to its home dimension and end up prisoners of the Earth-One Johnny Thunder who, to Canary's surprise, shows her a glass coffin containing the remains of her late husband and herself.
