One episode in and "Crisis on Infinite Earths" has already lived up to its promise as the biggest, most ambitious television crossover event of all time, gathering the heroes from across DC's entire history of TV and film.
"Holy All-Star Squadron," a visibly awestruck Ralph says, referencing the classic DC superteam as Killer Frost tells the others to ignore her colleague as it's his first crossover.
Created by Roy Thomas, Rich Buckler and Jerry Ordway, the All-Star Squadron -- who debuted in Justice League of America #193 in 1981 -- was a conglomerate of the Justice Society of America, Freedom Fighters, Seven Soldiers of Victory and various individual superheroes to aid the Allied Powers in winning World War II. Whether more Golden Age heroes are slated to join in the Crisis remains to be seen.
"Crisis on Infinite Earths" begins Sunday, Dec. 8 at 8 p.m. ET/PT on Supergirl, then continues in Batwoman on Monday, Dec. 9 at 8 p.m. ET/PT and in The Flash on Tuesday, Dec. 10 at 8 p.m. ET/PT. After the winter hiatus, the crossover will conclude on Tuesday, Jan. 14 in Arrow at 8 p.m. ET/PT and in DC's Legends of Tomorrow at 9 p.m. ET/PT.
