Inuarashi: I honestly think that Inu has a 0% chance at beating Jack, unless Neko somehow shows up to help him. I would be here all night if I tried to list all the reasons why I think Inu beating Jack solo is impossible, so I’ll just leave it at this: Inu is far too irrelevant in this arc to justify getting the glory of beating a Calamity, and he’s clearly not as strong as Jack when he doesn’t have access to Sulong. If Inu was a main character in Wano like Kyros was a main character in Dressrosa, then I could see Inu being the one to beat Jack for narrative reasons, but Inu got basically no screentime in the first two acts, and all of his fairly limited screentime in Act 3 was shared with 8 other people. He’s just not important
