Legion Timeline Roadmap v3

First posted in April 2020, then updated in Feb 2025. Here's the latest Legion roadmap for August 2025, now updated to try to show the simultaneous presence of both the Rebirth and Retroboot Legions in the current present, plus the Absolute Legion (aka Darkseid's Legion), plus highlighting the standings of all four mainstream heroic Legions. Let me know if you think I've messed something up or forgotten something!

Don't read anything into the "point" numbers here, it doesn't signify importance or anything, just there to denote what is branched off of what.

The four bright colors represent the four mainstream versions of the Legion, with their common names. I also added a layer for the Absolute Universe.

yellow = Reboot

orange = Threeboot

cyan = Retroboot (technically the inheritor of the pre-5YL history and continuity)

green = Rebirth

gray = Absolute Universe aka Darkseid's Legion

• 0.0: Earth history proceeds without Darkseid's essence permeating the universe
• 1.0: 1958-1985 (everything up to the beginning of Crisis on Infinite Earths; Adventure Comics  #247 to LSH v3 #17)

• 3.0: 2004-2009 (post Infinite Crisis "Threeboot"; LSH v5)
• 4.0: 2019-present (post Rebirth; LSH v8)
• 0.1: Earth history proceeds with Darkseid's essence permeating the universe (Absolute Universe; Darkseid's Legion)

Each of my breakpoints in the 1.0 section is a "mini-reboot" or a place with retcons and new continuity:

• In 1985, either the Crisis happens (1.1, as published 1985-89) or it doesn't happen (1.2, as seen on Earth-1985 which we haven't seen yet)
• At the end of the Magic Wars in 1989, either the Great Collapse happens (1.1.1, as seen in LSH v4 #1-4) or it doesn't (1.1.2, the Retroboot)
• I consider the Mordruverse itself (LSHv4 #5) to be an alternate reality, so it's not in this roadmap
• The Mordruverse aftermath created a world in which there never was a Superboy or Supergirl, and Valor and Laurel Gand filled their spots, giving 1.1.1.1 (we have not seen a timeline in which the Mordruverse did not happen, which would be 1.1.1.2)
• New 52 was arguably different from what had been before in the aftermath of Flashpoint, so that becomes 1.1.2.1 (and 1.1.2.2 would be a world where Flashpoint didn't affect the Legion). 
• Convergence (1.1.2.1.1) undid New 52 and brought back the Retroboot, as seen in the 2023-24 JSA series which ignored the New52 team deaths and other changes, but Flashpoint did happen.

And of course, we know that the there are lots of timelines out there that we just haven't seen yet, now that every timeline exists: the one where Crisis didn't happen (Earth-1985), the one where Zero Hour didn't happen and the 5YL timeline is still going, etc.
