- Follow the Leader: The success of this led to similar "back to basics" series like JSA and Titans, to the point both were spun off of events related to this (the arc "Crisis Times Five" serving as a Poorly Disguised Pilot for JSA and Titans starting with the JLA/Titans: The Technis Imperative miniseries).
- The Merch: During the last years they held the license to make DC figures, Hasbro released a line of action figures that was mostly KB Toys-exlcusive (with the last wave being at Toys 'R' Us) that was mostly repaints of figures from the Total Justice, Legends of Batman, Superman: The Man of Steel, Batman Forever, Batman & Robin, and Steel toylines, with the last few waves also acting as this for Young Justice.
- Name's the Same: Both the final arc of this run and a tie-in for 52 are named "World War III".
- Toyless Toyline Character: Hippolyta, Orion, Big Barda, Aztek, Oracle, Tomorrow Woman, and many members of Young Justice (outside of Red Tornado and the founding trio) never got toys in the JLA toyline. Additionally, the line had comic store-exclusive box sets that featured the majority of the holograms the Injustice Gang used to attack Star City, as well as Lex Luthor and the Joker. However, the Wonder Woman hologram, Luthor and Joker's Injustice Gang cohorts, and Darkseid (the Greater-Scope Villain of "Rock of Ages") never got figures—despite Darkseid also being the Big Bad of the Total Justice toyline.
- Unintentional Period Piece: This was DC Comics during The '90s, where they were knee-deep in experimenting with how much they could screw around with the status quo at the time. This means that JLA ends up being a premiere time capsule for everything about 90s DC from Superman's infamous mullet, to his Superman Blue electric form, to just Kyle Rayner's presence in general, to Aquaman's barbarian look, etc.
