Nintendo announced that, alongside the debut of Pokemon Legends: Z-A, Season 1 of the Z-A Battle Club Ranked Battle kicked off with Greninjite for Mega Greninja as a reward. People have until November 5, 2025 to fight in online matches to earn it. Note that you do need to pay for Nintendo Switch Online and grab the day-one patch for the game to take part.
There’s one requirement to earn Greninjite so you can Mega Evolve Greninja in Pokemon Legends: Z-A. You need to hit Rank K. This is accomplished by earning points as you take part in matches. While winning helps you get there faster, the nature of the competition here means that even if you don’t, it is possible to earn the Mega Stone without too much trouble.
The other rewards for getting to certain tiers in Z-A Battle Club Ranked Battle also came up for the first season. Regardless of what rank someone reaches, they’ll get at least one Nugget. Seed of Mastery Z-A shows up as an additional reward for ranks L through R. A Bottle Cap is included in the bundle if you hit between Rank F and K. Folks who manage to get to between Rank A and E will get all of the previous rewards, Sport Ball Poke Balls, and a Gold Bottle Cap.
Game Freak and Nintendo also brought up the major rewards for seasons 2 and 3. Again, they will be Mega Stones. Delphox’s Delphoxite will be the second one. Chesnaught’s Chesnaughtite will be the one awarded in the third season.

Pokemon Legends: Z-A is available for the Switch and Switch 2, and the Z-A Battle Club Ranked Battle Season 1 Greninjite will be available as a reward until November 5, 2025. After that, season 2 will begin.
