Headcanon that Barbossa's sword skills are genuinely frightening to other pirates.
In CotBP, his crew hesitates to take him on in the cave, despite all of them being undead and him being alone.
In AWE, Sao Feng, a Pirate Lord, surrounds him and Elizabeth in his bathhouse, outnumbering them by a long shot, but the second Barbossa suddenly gains a weapon out of nowhere, he resorts to taking a hostage.
I'm convinced Barbossa has genuinely come out of a 1 v XY completely unscathed at some point during his career and everybody feared him ever since.
