O-Powers
O-Powers are special powers that will help you progress through your adventure. These O-Powers come in many forms. Some powers may temporarily increase your stats, while others may make it easier to catch wild Pokémon. Still others may increase the Exp. Points or prize money you get from battle.
Offer O-Powers to Other Trainers!
The useful effects of your O-Powers are not just for you—you can also offer them to other Trainers around you so they can benefit from them, too. If a nearby player uses an O-Power, it will be displayed through your PSS, and you'll be able to use that O-Power yourself!
