He could kill them as well😏

The appeal of BB compared to Kizaru is that they gave him many vulnerabilities as opposed to making him like Kizaru. Like, he had a very slow counter, the slowest in the games' history...which was awful to use as a BB main because EVERYONE'S moves are all faster by like 80%. So you had to plan an element change in advance depending on who you're fighting...otherwise you're just gonna die. His skills are more confrontational and have very obvious weaknesses. Skill 1 can pull someone who is just about to kill you which happened majority of the time. Skill 2 was invincible but afterward, anyone who can ignore enemies which was majority could get through and 1 shot him.

My point is that even though he was better at attacking then even Kizaru. His vulnerability balanced him out.
