Barbara

Barbara the Bat is the mascot of the Japan only release Daigasso! Band Brothers (Jam with the Band is it's slated US name) for the Nintendo DS.

Character description
Barbara the Bat is a fun-loving rock starlet who plays the lead guitar in her own band, the Band Brothers, along with her little brother and her friends. She hates it when people do not address her by her full title.

In Super Smash Bros. Brawl
When Barbara the Bat appears, she plays her guitar for a few seconds, sending out musical shockwaves that damage your opponents and cause resonable knockback. This works in a similar fashion to Donkey Kong's Konga Beat.
