Brawl Point

From the Super Mario Wiki
Luigi, Mario, and Bowser's Special Points

Brawl Points, originally known as Special Points, are a stat in Mario & Luigi: Bowser's Inside Story and its Nintendo 3DS remake, Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey. They are functionally identical to Bros. Points from other Mario & Luigi games and are needed for Bowser to perform Brawl Attacks. As Bowser gains levels and obtains better pieces of clothing, his maximum amount of BP increases. Certain pieces of clothing will also reduce the BP cost of Brawl Attacks when worn. BP can be refilled by using Syrup Jars in the original game or Cheese in the remake.
