Barbara (バーバラ, Barbara), whose full name is Barbara the Bat, is the mascot of the Jam with the Band series.
Barbara debuted in the Japan-only game Daigasso! Band Brothers. She is the manager of the music store, Great Barbara (GB) Music, in Waruwaru Town, and an avid guitar player. She guides the player throughout the game and possesses a rather arrogant personality. She also appears in the Nintendo DS game Master of Illusion as owner of the magic shop.
As an Assist Trophy
Barbara appears as an assist trophy. She is unlocked for use after collecting 25 CDs. Her attack is similar to Donkey Kong's Konga Beat: upon appearing she remains in place for a few seconds, playing her guitar which produces musical shockwaves that damage the summoner's opponents and cause reasonable knockback. Her last soundwave has a bigger range and damage.
The manager of the music store GB Music in Waruwaru Town--her real name is Barbara the Bat. She leads the player through the game, showing her arrogant attitude as she cracks the whip at others but pampers herself. Her little brother's name is Tingtin the Bat. By the way, the "GB" in the name of her store stands for "Great Barbara," NOT "Game Boy."
As a costume
Barbara's trophy is exclusive to Super Smash Bros. for Nintendo 3DS.
As the manager of a slightly dubious talent agency, Barbara's always looking for people who want to join a band. She'll even teach you to play—whether you ask her or not. It's best to let her think she's taking advantage of you, even if she really isn't. Her hidden theme music really illustrates the contrast of darkness and light in her soul...or something.
