Some of these are passable, like the snake dude and Boa, and Doffy and warever that lady is....You can even think up an argument for Franky's copy there and maybe even Rob Lucci....
But come on, theres no excuse for the Kuma and Shanks copies there.
And this is the same retarded author who is soo shitty at making characters that he keeps making a slightly diferent version of his own characters in every single manga he makes.
