** 1.0: Louisoix, Nael van Darnus ([[spoiler: or rather Eula Darnus?]]) With their Nael Deus Darnus form as an alt.
** A Realm Reborn: Minfilia, Aymeric, with Lahabrea and/or Gaius van Baelsar as a villain [[spoiler: and then his [[HeelFaceTurn Shadowhunter]] version as an alt like Cecil or Yda/Lyse.]]

** Stormblood: Hien, Yugiri, with Zenos as a villain (and most likely villain overall), Yotsuyu (with her BT having her turn into Tsukuyomi), Fordola, Nero, Asahi.

** Shadowbringers: [[spoiler: Ryne]] and the Crystal Exarch; Emet-Selch as a villain. Potentially also Ardbert. Gaia as a purple unit. The new Warriors of Light (Granson, Lue-Reeq, Cerigg, Taynor, and Giott (unbearded too)). Vauthry and/or Ran'jit are also additional villain candidates.
** Endwalker: Reaper Zenos, Sage Alphinaud, Pre-Sundering Emet-Selch, Hythlodaeus, [[spoiler:Venat (with her BT having her turn into Hydaelyn)]], [[spoiler:Meteion (with her BT having her turn into the Endsinger)]], [[spoiler:Varshahn]], [[spoiler:Zero]], Fandaniel/[[spoiler:Amon]], Jullus.
* FFXV: Gladio, Ignis, Ardyn definitely. Aranea, Cor, and Iris also likely. Luna, Ravus, and Regis are less likely, but certainly possible. Somnus, Gentiana, Iedolas, Verstael, Loqi, Aera, and post-TimeSkip Talcott are other options. Y'jhimei is far less likely, but still a possibility. Movie characters like Nyx would be a surprise but I don't see it happening (though with [[Anime/FinalFantasyVIIAdventChildren Kadaj]] getting in it opens up the possibility for Nyx and possibly also Glauca/[[spoiler:Titus]]). Solara from ''Dawn of the Future'' would be an even bigger surprise.

*** Both Reno and Rude made it in right after one another. Kadaj made it in as well, opening up the possibility for other ''FF'' movie characters. Shelke was also confirmed. Cissnei also beat both Angeal and Genesis to the game, despite Angeal's data being in the game for a long time before this. Defying this list, ''Jessie'' has also made it in, likely due to her increased prominence and popularity from the Remake. Weiss from ''Dirge of Cerberus'' also made it in, increasing the likelihood of the other Tsviets. And in keeping with the trend of ''VII'' characters getting added to the Japanese version of the game right after the latest ''VII'' global release, Rufus Shinra has also been confirmed.

* FFXVI: Clive (both young and adult) and Joshua are the most likely, with other Dominants also being quite probable: Jill and Cid Telamon have good chances to appear; Benedikta, Hugo and Dion are less likely, and Barnabas as a villain, [[spoiler:with Ultima being very unlikely to join the playable roster]]. Even other non-Dominant party members [[spoiler:Gav, Byron, and even Wade]] and antagonists like [[spoiler:Sleipnir]] have a chance of joining.

** Dorgann and Kelger have been added, so Xezat, the remaining Dawn Warrior, is likely to follow suit eventually. King Tycoon might also be considered. [[GreaterScopeVillain Enuo]] and [[WiseOldTurtle Ghido]] are possible, though unlikely. Cid and Mid, less so.

** Voracious Resplendence: Altennia, Excenmille, Garazu-Horezu.
