Summary
Based on everything that’s been revealed so far aboutPokemon Legends: Z-A, the backdrop of Lumiose City’s futuristic urban redevelopment could offer an opportunity for Game Freak to get creative with its potential regional forms and evolutions. Since their introduction inPokemon Sun and Moon, regional variants of existing Pokemon are now among some of the series' most popular traditions, includingPokemon Legends: Arceusand its unique Hisuian Pokemon. Between this game and the latest Paldean variants featured inPokemon ScarletandViolet, it seems almost inevitable thatPokemon Legends: Z-Awill continue this trend.
But in contrast toLegends: Arceus,which revamped its regional variants as ancestral Pokemon from Sinnoh’s feudal past,Legends: Z-Awill instead have to look to the future if it plans to introduce its own regional Pokemon. However, with the confirmation thatLegends: Z-Awill be set within Lumiose City and not Kalositself, Game Freak has the chance to add another twist to regional Pokemon that takes inspiration from another real-world example of modern evolution. In doing so,Legends: Z-Acould become the firstPokemongame to show the future potential of regional forms instead of those past and present.

Predicting Pokemon Legends: Z-A’s Lumiose City and its Regional Pokemon
Exploring the Real-World Inspiration Behind Regional Pokemon
With Alola taking its inspiration from Hawaii and other Pacific islands, Gen 7 made waves when it adapted the real-world Darwinian theory of evolution by natural selection and jump-started an all-new tradition of new regional Pokemon with each generation.Pokemon’s latest generation expanded on this withScarletandViolet’s “regional fakes” or convergent Pokemon, another real-world example where separate species evolve in near-identical ways. As thenext potential mainlinePokemongame,Legends: Z-Aand its regional variants could go even further by once again taking inspiration from a more recent real-world phenomenon.
Due to increased human activity such as urbanization and pollution, it appears that certain plants and animals have already begun to adapt to their new city eco-systems through a process now known as “urban evolution” or “urban Darwinism.” Though the number of confirmed instances is limited, it already includes examples like moths becoming darker due to pollution and insects adapting to the high temperatures of heat islands. Between the official and rumored cases of urban evolution, this evolutionary phenomenon would be perfect for regional Pokemon inLegends: Z-Athanks to its Lumiose City setting.
How Urban Evolution Could Influence Pokemon Legends: Z-A
While there may already be a handful of regional Pokemon that fit the urban evolution model, like Alolan Grimer and Muk or Galarian Weezing,Legends: Z-Acould take a deeper dive into this through the game’s city as a “region.” WithLegends: Z-Apotentially giving Zygarde the spotlight, a story focusing on the impact humans have on nature and life would be perfectly suited toXandY’s Legendary trio if they are set to return. The table below outlines just a few instances of urban evolution thatLegends: Z-Acould take inspiration from when combined with Pokemon first seen in the Kalos region.
