By consuming the essence of the Smasher, you gain several boons:
*Channel the powers of every playable character in the Super Smash Brothers video game series, at their full power rather than just the limited movesets of the games. You can only channel one character's powers at a time, but you can switch between them on the fly.
*Grant other people these powers by creating a sticker of the character in question, which the target must then attach directly to their skin. These are indestructible stickers and can't be removed by anyone but you. You lose access to the powers of the character for whom you make a sticker, as long as they are being used by someone else. When you take back a sticker, it vanishes into your body as if you had never made it in the first place.
*When you're in a serious combat situation, items from the games may appear that you can use to turn the tide of battle. These items work exactly the same way they do in the games, which means they can be used by combatants other than you.
*You can also create 'amiibos' of the game's playable characters, clones of them with all of their powers who are 100% loyal to you despite how they may act in their source material. Yet like with the stickers, you lose access to those character's powers for as long as that amiibo is active. If a character has alternate costumes or appears as both genders rather than just one, you can choose what form they take as an amiibo. This can include alternate color schemes as well. When an amiibo dies, you can either choose to retake their powers or revive them. Note that choosing to retake their powers doesn't mean you permanently lose that iteration of the character. They stick around as a voice in your head offering advice and/ or encouragement, until you decide to make them a new body.
