Legion Chronological Roster: the Retroboot Legion

The membership of the retroboot Legion can be assumed to follow the membership of the original Legion up to the point of Crisis on Infinite Earths, for the most part. There are exceptions:
- Supergirl was never a member of the retroboot Legion
- Magnetic Kid may never have been a member of the retroboot Legion
- Star Boy was expelled from the Legion for killing Kenz Nuhor, just as in original Legion continuity, but may not have rejoined the team after that, or, if he did, may not have rejoined until much later
- Lightning Lad, Saturn Girl and Cosmic Boy may not have resigned from the Legion shortly before Crisis on Infinite Earths; if they did, they rejoined sometime after that

Between Crisis on Infinite Earths and the Lightning Saga, we know some things about changes to the Legion's membership, but not the order of them. Among the comings and goings
- Chameleon Girl joined
- Karate Kid II joined and later resigned
- Night Girl joined
- Karate Kid I rejoined

Lightning Saga: It's not clear who all is and is not a Legionnaire in this story. We see Karate Kid, Wildfire, Dream Girl, Starman, Dawnstar, Timber Wolf and Sensor Girl, and others are mentioned, like Lightning Lad, Brainiac 5, and Night Girl. Reading it, I couldn't tell if Starman was a Legionnaire or not. Plus, Legionnaires present in this story later disappear, like Dream Girl and Sensor Girl. (?)

Superman and the Legion of Super-Heroes: By the end of this story, the Legion has an effective membership of Blok, Brainiac 5, Chameleon Girl, Colossal Boy, Cosmic Boy, Dawnstar, Invisible Kid, Lightning Lad, Lightning Lass, Night Girl, Phantom Girl, Polar Boy, Saturn Girl, Shadow Lass, Shrinking Violet, Sun Boy, Timber Wolf, Ultra Boy, Wildfire. Other, missing, Legionnaires are considered to be on the team even in absentia. But I think the only way to do it is to treat them as being on a leave of absence or something until they're reunited with the team. I'm not treating Superman as a full-time member either. (19)

Final Crisis: Legion of 3 Worlds: The Legion tracks down Mon-El and the White Witch in this series, although the White Witch doesn't stay with the team. Bouncing Boy and Duplicate Damsel return, and Gates and XS join. That makes 24 Legionnaires heading into Adventure Comics: Blok, Bouncing Boy, Brainiac 5, Chameleon Girl, Colossal Boy, Cosmic Boy, Dawnstar, Duplicate Damsel, Gates, Invisible Kid, Lightning Lad, Lightning Lass, Mon-El, Night Girl, Phantom Girl, Polar Boy, Saturn Girl, Shadow Lass, Shrinking Violet, Sun Boy, Timber Wolf, Ultra Boy, Wildfire, XS.
