>Legends Arceus has regional variants of a past version of Sinnoh (Hisui)
>Legends Z-A has mega evolutions

Assuming every Legends game has each own twist on "new forms for old pokémon", what could they do for Legends games set in other regions?

Some ideas
>Legends Mew
Cloned pokemon, like those from the Mewtwo movie
>Legends Celebi
Day/night/twilight forms (like Lycanroc). Different forms can be found in the wild or be evolved depending on the time of the day
>Legends Deoxys
More mega evolutions, probably. Or maybe primal reversions instead
>Legends Kyurem
Seasonal forms, similar to those of Deerling/Sawsbuck
>Legends Necrozma
Ultra Space forms. Kinda like regional forms but more alien-looking
>Legends Eternatus
Gigantamax forms. Maybe Blue Gigantamax too, like Calyrex's dynamax
>Legends Terapagos
The Terastal forms that were rumored to be in the Indigo Disk but turned out to be bullshit
