"A Little Bit of Everyone" from JLA: Year One #5 (DC, 1998) by Mark Waid, Brian Augustyn, Barry Kitson and Michael Bair
Mark Waid knows how to write superhero comics. Period. Beyond showing rather belated retconned post-Crisis adventures of the early Justice League of America (sans Superman and with Black Canary in Wonder Woman's spot), and filling in what might have happened in between issues (à la Untold Tales of Spider-Man), Waid also gave the characters humanity. How were their personalities instrumental in creating a team that would last for so long? My favorite part? How Aquaman had to adapt to speaking out of water, and everyone had to tell him to speak up!
