As much as Brook normally goofs around on the ship engaging in acts of silliness with Luffy, he is still a formidable opponent. Due to his previous experiences and skills that he amassed from the days when the Pirate King, Gol D. Roger was still active, Brook, in all respects, is a veteran pirate (though these attributes are somewhat downplayed by his overall demeanor, along with the fact that his isolation in the Florian Triangle seemed to have eroded his knowledge of modern society). Though he often gets scared easily by powerful enemies or the supernatural, he can be very calm and fearless to defend his crew. Examples are such as when he cleverly realized he could trick Jora to defeat her, and when he willingly sacrificed himself hoping to hold back Kuma.
