Like so many other competitive online video games, Pokémon Unite has a Battle Pass system. The game may be free-to-play, but it still needs to make some money for it to continue being supported at the end of the day. If you purchase the Battle Pass in Pokémon Unite, you will work your way through its various tiers to unlock various cosmetics and items that can be used in the game. Here are all of the rewards you will see in the first Battle Pass for Pokémon Unite.
Once you have reach rank 90 and got the pirate outfit for Cinderace, you can then continue doing missions to earn Battle Pass Prize Boxes. From the looks of things, these appear to be loot boxes that will give you various rewards when opened. You can have up to 25 Battle Pass Prize Boxes unopened at a time.
