@uniaka:
Now I want Cesar clown to join. He has his dream, to become best scientist instead of that fraud, vegapunk.
I actually agree. Not that he should be a strawhat but he should be kept under tabs by Luffy. If he's not kept under control he can literally do island scale damage and generational damage to people. He should be kept on an island where he is forced to do experiments that help people(like he did on Zou) with someone strong enough to defeat him like Barto or Cavendish. Or maybe Law can just keep his heart. Caribou might have the same fate after Wano. A lot of these guys are better off with Luffy so they wont cause to much trouble and their only other real options are leaving the grandline or being killed by or made slaves of the other Yonkou or the WG.
That being said if we get somebody from the wano arc to join I hope its a supernova, like Bonney or Law. Also I think momo and otama
should become Luffy's cabin boys.
