I started to make a poll but there's just too many different line-ups over the years to include them all. Odds are, there won't ever be a perfect line-up of characters, but which comes close for you?
Line-ups can include comics (Silver Age, Satellite years, JLI/America/Europe, JLA, etc...) or cartoons (Super Friends, Challenge of SF, JLU, etc...) tv shows, video games, or films.
It must have been an existing line-up (no "I wish we had had this line-up).
Mine is definitely the Satellite Years. What's yours?
