Here's all the times Barret uses symbols to swear :


"Barret: Huh? Never expect ta hear that outta someone like you. …you jes' full of surprise. The upper world…a city on a plate… It's 'cuz of that #$@*&# 'pizza', that people underneath are sufferin'! And the city below is full of polluted air. On topa that, the Reactor keeps drainin' up all the energy.

Barret: *$&%! Someone blew it…

Barret: Where's its #%$*#&$ head? This whole thing's stupid. Let's keep goin'.

Barret: &^&%…surrounded, huh? If I was alone this wouldn't be a thang but, I gotta reputation to protect.

Barret: $*$&%……awright. Go Northeast to a town called Kalm. If something happens, we'll meet up there. 'Sides, we can't have 5 people strolling down the fields. It's too dangerous. Split us into 2 parties…

Barret: So PLAY! …messin' round %&*$#&! Don't forget we're after Sephiroth!

Barret: That #*$&#&' kid!!! Grrrrrgh!! Arrrrrgh! Uhhhhhhhhhhhh!! She was after our materia from the start!! She went north! When I get my hand on her, I'll get our materia back! C'mon! We're goin' after her!

Barret: Damn dirty-playin' @*#&$@*#&@@#!"
