List of badges in Paper Mario: The Thousand-Year Door
Note: Badges that have a "P" at the end of their names are identical to their non-"P" counterparts, but affect Mario's partner. Equipping more than one of the same badge doubles the FP cost of the move for each extra badge equipped. Equipping more then one of the same attack badge increases the attack's power by 1 and/or increases the duration of the applied status effect by 1. Equipping multiple Charge badges gives Mario or his partner 1 extra power when charging. When both the W Emblem and L Emblem are equipped, Mario's clothes will change into Waluigi's clothes.
2 - There is a common misconception that the Feeling Fine badges have an effect on Poison Shrooms. In reality, all they do is stop the user from being poisoned. There is a slight chance that the user will not be poisoned or lose half HP, but instead will be fully healed. This is simply a random occurrence; wearing these badges makes no difference. This has been proven by extensive testing.
3 - All badges that can be stolen from an enemy can also be dropped after battle; the reverse is not true.
