3. Year One Team

Green Lantern, The Flash, Aquaman, Black Canary, Martian Manhunter. The original Justice League, according to Justice League: Year One.

Also, JLA Year One is far and away my second favorite Justice League-centric story of all time (Favorite being New Frontier). The Year One team, despite missing Superman, Batman, and Wonder Woman, is still just as iconic as ever.

I personally really like the retcon of having Black Canary be a founding Leaguer instead of Wonder Woman, partially because I prefer Canary, and partially because it gives the League a tangible connection to the Justice Society of America. The team united to fight the Appelaxians, and held together for a full year before admitting new members.

Batman eventually joined the team after their battle with Fire Eyes, and Hawkman would join after the fight with Wotan and the JSA (All of that is available in the criminally underrated JLA: Incarnations miniseries, by the way). But yeah, I flipping LOVE the Year One team.
