As previously mentioned Capitano is arrogant but that's only to hide the fact that he's a coward. What I think this means with reference to the Tales of Winter is that he's a less pompous brand of arrogant compared to Signora. Instead he's more like a band leader. He acts very confidently and that instills morale in his people. This is why Viktor likes him over Signora who's arrogant and calls even Archons filthy rats.
Whenever we find him he'll have the full support of his henchmen. But when we finally corner him into a fight it'll be revealed he was terrified that we'd challenge him and maybe the fight itself might even be more like us against tons of Fatui with him acting as Support instead of a direct confrontation. He'll keep summoning endless allies until we can take him down something like the Kairagi Bounty.
This is why I feel like he'd fit more with the Weekly Boss of Natlan during the Archon Quest than Pantalone. He'd act like a foil for the Murata in terms of my theory about Murata. Where he's actually a coward putting up a confident front Murata will still be a brave yaksha underneath her fear from her time serving Zhongli adding that extra layer that Capitano doesn't have.
Who do you think will be the Fatui culprit in Natlan? Is there anyone who might fit the story better in your opinion?
