Attack FX P is a badge in Paper Mario: The Thousand-Year Door.
Effects[]
As the name may imply, this badge is not a partner badge, and thus only affects Mario. Mario can wear this badge for zero BP, and wearing the badge makes some of his attacks make a loud roar sound.
It is obtainable from the Lovely Howz of Badges later on in the game, around the completion of Chapter 6. It is on sale for the steep price of 100 coins and sixty if it is discounted.
