All Pokemon Games With Mega Evolution

Mega Evolution is, without a doubt, one of the most popular mechanics in the Pokemon franchise, as this mysterious phenomenon allows trainers to unlock an incredible and powerful new transformation for their Pokemon that can quickly turn the tide of any battle.

This mechanic has existed since 2013, but, much to the disappointment of Pokemon fans, it hasn’t returned in all the other games released since its introduction. It may not be entirely clear to some people exactly which Pokemon games have Mega Evolution in them and which ones don’t, so this guide will detail which ones it is available in, including upcoming releases that are set to bring it back after a seven-year-long absence.

Updated on April 16, 2026, by Julián Fernández Loyarte:The original version of this list came out back in August 2025, when everybody was anticipating the long-awaited return of Mega Evolution in both Pokemon Legends: Z-A and Pokemon Champions. Now that those two games are finally out, we have a better idea of how this mechanic was changed, how it has been impacting the competitive scene, and which Pokemon got some much-needed Mega Evolutions after all these years. As a result, this list has been updated to properly reflect all those recent changes.

Pokemon X And Y

The Games That Introduced Mega Evolution

The release of Pokemon X and Y was a monumental moment for the franchise. Not only were they first mainline games made with 3D graphics, but they also introduced Mega Evolution, and this fascinating new mechanic immediately captivated the entire fan base. Along with a plethora of new Generation Six Pokemon, Eighteen Mega Evolutions were added in X and Y, including Mega Mewtwo, Mega Gengar, Mega Scizor, Mega Blaziken, Mega Gardevoir, and many more.

Weirdly enough, however, players could only use two Mega Evolutions during a regular play-through: Mega Lucario and the Mega Evolved form of whatever Kanto starter they chose at Lumiose City. Combined with the fact that only three NPCs used Mega Evolutions against the player (Korrina, Lysandre, and Diantha), this mechanic felt surprisingly underutilized in its debut game. Nevertheless, it still completely redefined the online competitive scene, with many Mega Evolutions reaching the Uber tier alongside most Legendary Pokemon.

Pokemon Omega Ruby And Alpha Sapphire

The Hoenn Remakes Put A Bigger Emphasis On Mega Evolution

A little over a year after X and Y, Pokemon fans finally received the Generation Three remakes they had been waiting for over a decade: Pokemon Omega Ruby And Alpha Sapphire. While these two games were obviously in full 3D and had several significant quality-of-life improvements, they also took advantage of the brand-new Mega Evolution mechanic that had been introduced in the last entry.

Eighteen more Mega Evolutions were added in Omega Ruby and Alpha Sapphire, which mostly included forms of Pokemon that are native to Hoenn, like Mega Camerupt, Mega Sharpedo, Mega Sableye, Mega Sceptile, and Mega Swampert (which finally rounded up the Starter Trio after Mega Blaziken had been introduced in X and Y). Even Mega Rayquaza made its debut in these remakes, which quickly became one of the most overpowered Pokemon ever made. Additionally, a lot of NPCs, including the entire Elite 4 and the Champion, chose to Mega Evolve their signature Pokemon during their initial encounters, and it made the overall experience a lot more fun and challenging.

Pokemon Sun And Moon/Ultra Sun And Ultra Moon

Mega Evolution Took A Backseat In Generation Seven

Pokemon Sun and Moon kick-started the seventh generation of Pokemon, which meant that a brand-new battle mechanic tried to take Mega Evolution’s place: Z-Moves. Nevertheless, despite the introduction of these over-the-top single-use moves, Mega Evolution was still available during this generation, meaning that both mechanics could interact with each other in battle.

However, there was a huge downside: no new Mega Evolutions were introduced in either Sun and Moon or their direct successors, Ultra Sun and Ultra Moon. This beloved mechanic took a backseat during this entire generation, as it was nowhere to be seen during the main story and could only be accessed in the post-game. These games were also notorious for including Pokedex entries of all the Mega Evolved forms, but, weirdly enough, most of them claimed that these transformations hurt the Pokemon and had a negative influence on their behavior.

Pokemon Let’s Go Pikachu And Let’s Go Eevee

Mega Evolution’s Final Appearance Was Quite Underwhelming

In 2018, Game Freak and the Pokemon Company released Pokemon Let’s Go Pikachu and Pokémon Let’s Go Eevee, two new Generation One remakes that implemented the more casual catching mechanics from Pokemon Go. Being able to explore a 3D reinterpretation of Kanto appealed to both new players and long-time fans, but a few new changes and mechanics were also added to keep things interesting and differentiate these games from the previous Generation One remakes, and Mega Evolution was one of them.

However, there was a catch: since Let’s Go Pikachu and Let’s Go Eevee only feature Generation One Pokemon, only pre-existing Mega Evolutions from that generation were included, not to mention that not a single new one was added. While the inclusion of Mega Evolutions made the experience a bit more fun and more challenging, it’s worth pointing out that these games are missing some of the series’ core mechanics – like abilities and held items – so they didn’t have as much of an impact on the gameplay as they did in previous games.

Pokemon Legends: Z-A

Mega Evolution Is Finally Back After Seven Long Years

When Game Freak announced that the next entry in the Legends subseries, Pokemon: Legends: Z-A, would have Mega Evolution in it, everybody was absolutely ecstatic, since this mechanic had been absent from the mainline Pokemon games for over seven years. Fortunately, the final product did not disappoint, because not only did it introduce a batch of new Mega Evolved Pokemon, it also recontextualized and revitalized the entire gimmick.

Mega Evolution is not only present in Pokemon Legends: Z-A: the entire game revolves around it. The main campaign sees players confronting various Rogue Mega Evolved Pokemon (whose battles are both challenging and entertaining), and almost every participant of the Z-A Royale uses one as their ace. Of course, the base game introduced new Mega Evolutions for a vast array of Pokemon from almost every generation (like Meganium, Feraligatr, Emboar, Dragonite, Hawlucha, Malamar, and countless others), but its DLC expansion, “Mega Dimension,” went one step ahead and added even more, many of which most fans never saw coming, like Mega Baxcalibur, Mega Scovillain, Mega Crabominable, and the Z-Megas.

Needless to say, Pokemon Legends: Z-A is the perfect game for any die-hard fan of Mega Evolution.

Pokemon Champions

Mega Evolutions, Z-Moves, And Terastallization Will Finally Meet In One Game

A few months after the release of Pokemon Legends: Z-A, Pokemon Champions brought the mechanic back to the franchise’s turn-based battles and, by extension, its massive competitive scene. What made this comeback even more exciting is the prospect of Mega Evolution clashing with other generational mechanics, like Z-Moves or Terastallization, but, at the moment of writing, it’s the only one available in the first season of this free online game.

The return of Mega Evolution in Pokemon Champions has been especially fascinating because the mechanic has been gone for almost a decade, meaning that many Pokemon that can use it have seen various nerfs and buffs ever since, and some of them (like Mega Charizard Y or Mega Blastoise) have successfully overcome power creep to position themselves at the top of the competitive ladder. Additionally, players also have access to some of the Mega Evolutions that debuted in Legends: Z-A, and many of them have been dominating the meta so far, with two prominent examples being Mega Froslass and Mega Eternal Floette.
