Pokémon Legends: Z-A Season X Brings a Free Shiny Xerneas and a Very Restricted Ruleset

On Thursday, Pokémon developer Game Freak began giving Pokémon Legends: Z-A players a free shiny Xerneas, the legendary introduced in Pokémon X. That gift will come in handy for the new season of Legends: Z-A's multiplayer, which has a very restrictive ruleset for what Pokémon can be used.

Season X, the game's 20th season, began on Friday. Even though Mega Evolutions are Legends: Z-A's main battle gimmick, Serebii reports that only Raichunite X, Charizardite X, and Mewtwonite X Mega Stones are allowed in Ranked Battles. Legendary Pokémon are banned, except for Mewtwo and Xerneas.

Season X will last until Dec. 11. That's around the same time shiny Yveltal, Pokémon Y's box legendary, will start being distributed. Don't be surprised if next season is Season Y and has a similarly restrictive ruleset.

Pokémon Legends: Z-A Season X rewards

Pokémon Legends: Z-A's Ranked Battles pit four trainers against one another using the game's unique real-time battle mechanics. You'll field a team of three Pokémon and earn a point for every Pokémon on your opponent's team that you knock out. All Pokémon will be set to level 50, regardless of the team's base level. Mega Evolution is key to victory, so expect to see a lot of Charizards, Raichus, and Mewtwos this season.

Season X will reward you with Greninjite, Delphoxite, Chesnaughtite, Baxcalibrite, Sceptilite, Swampertite, and Blazikenite stones for earning Rank Y through Rank S, respectively. You'll also get a bunch of different types of Poké Balls and exp. candies as you go. Check out the full list of rewards on Serebii.
