Franklin Badge

The Franklin Badge (Japanese: フランクリンバッヂ in Mother and Mother 3, フランクリンバッジ in Mother 2) is a reoccurring item in the Mother series, and also makes an appearance in Super Smash Bros. Brawl. It functions differently in every game that it appears in.

Mother
Two Franklin Badges are found in Mother, the first being given to Ninten by Pippi after rescuing her, with the second being found in Duncan's Factory. If in a character's inventory, it automatically reflects PK Beam γ back to the enemy, allowing the character to survive an otherwise automatically fatal PSI attack.

EarthBound
Only one Franklin Badge is found in EarthBound, being given to Ness by Paula before he faces Mr. Carpainter. Unlike in the previous game, it reflects all lightning-based attacks back to the enemy if in a person's inventory, instead of PK Beam γ.

Mother 3
The Franklin Badge is given to Lucas indirectly by Flint in Chapter 7, originally as a Courage Badge. However, after giving it to a Mr. Saturn in Saturn Valley for inspection and cleaning, it is revealed that the Courage Badge was merely an old and rusted Franklin Badge. It is given back to Lucas after he meets Ionia in Argilla Pass, and stays in the key items section of the inventory, as opposed to being able to stay in an individual's inventory. Because of this, it will only deflect lightning for Lucas. It otherwise behaves similarly as it does in EarthBound.

Super Smash Bros. Brawl
The Franklin Badge makes an appearance in Super Smash Bros. Brawl. Here it is a trophy and item. Its purpose is to deflect projectile attacks, like many attacks other fighters have. The Franklin Badge only stays temporarily however.
