For me, its a simple reason why I like this character. His will and fearlessness. Even when facing impossible or dire odds the guy never gives up. He lost an arm to the Shanks pirates and still kept going. When kaido first landed, he fought kaido to his absolute limit, was willing to die protecting his will/crew than surrender. He fought BM to his limit. During wano we saw some of more of his interactions with killer which was nice, just hoped to see more. Its clear he shares a strong bond with killer/his crew kinda similiar to luffy. And if anything his backstory regarding how his crew was formed makes him even more likeable. He doesn't have any grand destiny, god fruit, legendary ancestors, legendary blades etc...He just has a strong will, no fear and crew that trusts him.
