What Is the Z-A Battle Club?

The Z-A Battle Club in Pokémon Legends: Z-A features Link Battles where players can enjoy battling in real time. Up to four players battle to defeat as many of each other’s Pokémon as they can within the time limit of three minutes, and they’re ranked from first to fourth based on how they do. Keep a close eye on the tide of battle while using a variety of moves and Mega Evolutions at your disposal to keep on the offensive, defeat the most Pokémon, and seize victory.

Two Ways to Play

There are two ways to play in the Z-A Battle Club: Private Battles, where players can enjoy playing against friends, and Ranked Battles that allow players to match up against random players from around the world.

You can receive a variety of rewards through Ranked Battles. Three types of rewards are offered: battle rewards that you get after each match, promotion rewards that you get when you rise up a rank, and season rewards that you get when the season ends and depend on your rank.
