That chapter is pure gold for my soul. Eustass Captain Kid, finally you can take that Rat Out!!
for the chapter, I got some points to mention, specially with the spoiler in mind:
Apoo attacked luffy and Zoro with his hax power, both mention they just didn’t understand. So they decided to leave. Important here, they got no significant damage.
Secondly. Apoos range seems pretty limited and needs some time to prepare. So he needs to change his teeth, or arms... anything into a music tool (his teeth are different in different panel, so I think he need To change them too). And together with the time he need to prepare, his Defence seems pretty bad.
he saw kid coming, kid yelled loud and clearly and still apoo was not able to do anything except have a deeply scared face. He got punched in the wall without any Defence or counterattack, while he saw the attack coming.
so I take for me:
Apoo has a strong offense with preparations, but his Defence is weak. He is kinda the other side of the medal from Bege, which had lacks in offense, but an immense defense.
