While the Nintendo community continues to recover from the impact of recent Game Freak data leaks, new potential details about the upcoming Pokemon Legends: Z-A game allege that certain Legendary and Mythical Pokemon will receive all-new Mega Evolutions. Dubbed the "Teraleak" among fans, the scale of the leaked content supposedly includes extensive beta and unreleased Pokemon designs, the source code for Pokemon Legends: Z-A and next Gen 10 games, and even information about Nintendo's closely guarded Switch 2 or "Project Omnibus." However, among these leaks was the reported reveal of two new Mega Evolutions for two key Legendary and Mythical Pokemon.
The return of Mega Evolution was teased during Pokemon Legends: Z-A's announcement trailer, but fans have so far been left in the dark about which Mega Evolutions would be returning if not all, or if the Pokemon Legends: Arceus follow-up would introduce never-before-seen Mega Evolutions. Yet while earlier Legends: Z-A leaks had outlined a handful of returning or all-new Mega Evolutions like those rumored for its starter Pokemon, the latest Teraleak has seemingly revealed potential credible information about Mega Evolutions for Zygarde and Zeraora. With Game Freak confirming the data breach, these newfound revelations could offer fresh insight into the upcoming Legends: Z-A.
Breaking Down the Details of Pokemon Legends: Z-A's Mega Evolution Leak
Though the Game Freak breach was substantial, the specific leaks regarding Pokemon Legends: Z-A's new Mega Evolutions are unfortunately limited to just one tweet of many from Centro Leaks over on X. The find was credited to fellow X user Mootmonthly who discovered content potentially confirming Mega Zygarde and Mega Zeraora, with the former alleged to even appear at some point in the Pokemon anime. However, unlike similar leaks for beta or unreleased Pokemon, there don't appear to be any potential designs for these Legendary and Mythical Pokemon yet, nor are there any other specifics about potential stats or type changes.
Possible Revelations from Pokemon Legends: Z-A's Mega Evolution Leak
Between the game's namesake and the chosen setting of Lumiose City in Kalos, it seemed inevitable that the third member of Pokemon X and Y's Legendary trio, Zygarde, would be Legends: Z-A's mascot Pokemon. While the recent leaks corroborate this theory, Zeraora's inclusion was initially surprising, though potentially self-explanatory when linking the start and end of its name to the game's "Z-A" moniker. Still, up until now, Zygarde and Zeraora have shared few other connections beyond both appearing in Pokemon Ultra Sun and Moon, which could mean Legends: Z-A will build new ties between Pokemon Gen 7 and Gen 6's Mythical and Legendary Pokemon.
However, Zeraora's return with a new Mega Evolution could instead parallel Legends: Arceus' introduction of Enamorus as a fourth member of Gen 5's force of nature Legendary Pokemon trio, especially as the rumored anime appearance for just Mega Zygarde singles it out from the pair. Moreover, with Zygarde's already existing 10%, 50%, and Complete forms and a stronger connection to Gen 6's Kalos region, it appears that the spotlight is focusing on Pokemon Legends: Z-A's Zygarde mascot, rather than Zeraora. But if true, then this could hint at a returning short-lived gimmick last seen in Pokemon Omega Ruby and Alpha Sapphire.
The Potential Return of Primal Reversion in Pokemon Legends: Z-A
The debut of the Primal Reversion feature helped Omega Ruby and Alpha Sapphire up the Mega Evolution ante when it came to the Gen 3 remakes. But much like Mega Evolutions, Primal Reversion has been absent from mainline Pokemon games since then, even despite its surviving popularity among fans and appearances in spin-off games like Pokemon GO. However, similar to Legendary Pokemon Groudon and Kyogre, the leaked new "Mega Zygarde" could potentially be a new Primal Reversion, and this "Mega" form playing a key role in Legends: Z-A's larger story and world-building.
