For some reason, it's common for badges to be depicted as either giving special abilities to or augmenting the special abilities of the wearer. This could be rooted in the fact that military officers and the like wear them as symbol of [[AuthorityEqualsAsskicking authority]]. Authority is by no means necessary to use ''these'' babies, however.

This trope is common in {{RPG}}s, where they will be collected as equipment.

[[IThoughtItMeant Has nothing to do with]] [[ImprobableWeaponUser using sewing needles, tacks, pushpins, or the like as weapons]].
* In ''Manga/{{Bleach}}'', Ichigo has badge that can, among other things, detach his soul from his body.
* In ''Franchise/SailorMoon'' the main character has a brooch which serves as both a Transformation Trinket and a holder for her Power Crystal. Chibi-Chibi also gets one later on.
* In ''{{Voltron}}'', the keys to the lions hide themselves as pins.
** In ''VoltronForce'', the keys are required to activate Voltcoms.

* E.E. "Doc" Smith's ''Literature/{{Lensman}}'' series. The Lens, which is the badge of the Lensmen of the Galactic Patrol, gives the wearer a variety of useful mental powers, including language translation. It will also kill anyone who touches it other than its owner.

* TabletopGame/DungeonsAndDragons has a handful of magical pins/periapts/scarabs/brooches, starting with 'brooch of shielding' which protects against Magic Missile and 'scarab of protection' which before D&D3 gave a saving throw against spells normally not allowing it, in later versions gives spell resistance and absorbs a number of lifeforce-draining or death attacks.
** ''TabletopGame/ForgottenRealms'' [[HeroSecretService Harper]] pins (AD&D2 ''The Code of the Harpers'' / D&D3 ''Magic of Faerūn'') give their wearers a bonus against mind-affecting effects, immunity to detection spells/psionics, Magic Missile and electricity/lightning attacks. They also blacken and start to jangle if worn by an evil being.

* In ''Videogame/EarthBound'' (and the other VideoGame/{{MOTHER}} games), one of the earliest really useful special items you get is the [[Creator/BenjaminFranklin Franklin]] Badge, which reflects electrical attacks. It should be noted that in Videogame/{{MOTHER1}}, the Franklin Badge only reflected PK Beam Gamma, which was a one hit KO.
* In ''Videogame/FinalFantasyTacticsAdvance'', certain characters wear a ribbon (the military style, with a badge) that makes them exempt from all laws.
* In the ''Videogame/{{Mario}}'' [=RPG=]s, badges affect stats and sometimes have more interesting effects. In PaperMario and [[Videogame/PaperMarioTheThousandYearDoor its sequel]], they are Mario's sole form of equipment, and do anything from giving the player extra information, to giving Mario extra moves, to giving already existing functions more effectiveness, to boosting Mario's stats when low on health. They have stat-boosting functions in ''VideoGame/MarioAndLuigiSuperstarSaga'' and ''VideoGame/MarioAndLuigiPartnersInTime''. In contrast, ''VideoGame/MarioAndLuigiBowsersInsideStory'' and ''VideoGame/MarioAndLuigiDreamTeam'' have a badge system where an in-battle badge meter can be filled up with successful attacks; the exact advantage given is determined by Mario's badge, while the rate and requirements for filling the meter up are determined by Luigi's badge.
** Just some of the effects the badges give in Dream Team is worth noting... badges in that game can freeze time, act as a ResetButton, give the characters a forcefield or have the chance of taking out everyone in battle in about a minute. They can also be charged up and kept in reserve til necessary, making them act more like superpowers than badges.
* ''VideoGame/TheWorldEndsWithYou'' is built around this trope; every "player" in the "game" the protagonists are trapped in gains PsychicPowers from one. Neku, the PlayerCharacter, is unique in that he can use more than one (thus he can use pins in a PowersAsPrograms style). Oh, and the BigBad's EvilPlan is [[spoiler: to use modified pins to wire everyone up to a HiveMind. Neku's power makes him the best hope the MysteriousBacker has of countering it.]]
* In ''Videogame/{{Pokemon}}'', badges obtained by defeating gym leaders allow the player character's traded Pokemon to listen to them instead of ignoring orders. In early games, badges permanently gave a boost to a Pokemon's stats in battle.
* Many of the trinkets in ''Videogame/WorldOfWarcraft'' fall into this category, although it's hard to tell with some of them because their names are so vague.
* In the fourth installment of the ''VideoGame/EpicBattleFantasy'' series, some of stat-boosting or ability-granting pieces of flair are badges.
