In "When We First Met", we spotlight the various characters, phrases, objects or events that eventually became notable parts of comic lore, like the first time someone said, "Avengers Assemble!" or the first appearance of Batman's giant penny or the first appearance of Alfred Pennyworth or the first time Spider-Man's face was shown half-Spidey/half-Peter. Stuff like that.

Reader Dan W. wrote in to ask, "With the Justice League coming out I was wondering when was the first time the Justice League fought Darkseid ?"

After spending the 1970s mostly just appearing in New Gods stories, Darkseid made his first appearance against the Justice League in 1980's Justice League of America #183 (by Gerry Conway, Dick Dillin and Frank McLaughlin). This was tragically the last issue drawn by Dillin.

The issue is the annual Justice League/Justice Society team-up. This time, they both teamed up with the heroic New Gods to investigate how New Genesis was suddenly missing a bunch of citizens. They were soon found working on a weird device...

The heroes attack in the next issue, which is now drawn by new regular artist, George Perez...

In the final part of the story, Firestorm hilariously defeats Darkseid one-on-one....

Thanks for the question, Dan! If anyone else is curious about a notable comic book first, drop me a line at brianc@cbr.com!
