Badge

Badges are used in Paper Mario, Mario & Luigi: Superstar Saga, Paper Mario: The Thousand-Year Door, and Mario & Luigi: Partners in Time. In all four games they are equipped as accessories.

Paper Mario Series
Badges can be obtained in a multitude of ways in the Paper Mario series. Most badges provide a special attack for Mario and consume BP (Badge Points) when equipped.

Paper Mario: The Thousand-Year Door
Notes: Equipping more than one of the jump or hammer attack badges Mario has already obtained doubles FP requirements, but increases attack power by 1. When wearing both Double Dip badges, Mario can use Triple Dip for 8 FP. For more than one Charge badge, Mario or his partner gains an extra 3 attack power for 2 FP for the next turn. When both the W Emblem and L Emblem are equiped, Mario will wear Waluigi's clothes.

Total number of badges: 85.

* When using P-Down D-Up (P) the defense point added additionally decreases damage received from a defense-piercing attack by 1, whereas even Defend Plus doesn't protect against such an attack.

Unused Badges
These badges were found in the game's ROM, but cannot be normally found in the game. Some information may be incomplete.

Paper Mario
Note that the badge number column lists the number of the pointer in the ROM referencing each badge. It is included here primarily to give a standard designation to the unnamed badges.

Mario & Luigi: Superstar Saga
In this game, badges do not provide new attacks. However, they do increase POW and BP, and sometimes have other special features. BP is not Badge Points, but Bros. Points, and serves a completely different function. Each brother can only wear one badge at a time. If a small number is shown in the last column, refer to the end of the table for that effect.

– No effect. 1 Increases counterattack power. 2 Increases POW in battle. 3 Recover 2 BP every turn. 4 Enemies will drop items more often. 5 Recover HP equal to 1/10 damage dealt with Hand attacks. 6 Increases frequency of Lucky hits. 7 Recover HP equal to 1/10 damage dealt with Jump attacks. 8 The more Mushrooms in your possession, the more damage your attacks will do. 9 Recover HP equal to 1/10 damage dealt with Hammer attacks. 10 Inflict twice as much damage on Spiny enemies with Jump attacks.

Mario & Luigi: Partners in Time
In the second installment, the setup is the same, except that badges only add special effects to each of the four brothers. Clothing increases and decreases all the stats in this game. If the Location is "Fawful's Bean 'N Badge", the price is in number of beans.

Trivia

 * Super Paper Mario eliminates the use of badges for there is no RPG style battling system. Although, there are two items that were previously badges in the past games: Power Plus and HP Plus, they retain their main purpose. Power Plus boosts the character's attack power by one and the HP Plus boosts the character's Heart Points by five. But with the badges they had to be equipped and could be unequipped. In the most recent game, once it is used, it's permanent.
