I'm already surprised that he left the Marine base without Akainu's permission. This is huge imo. He barely disobeys orders.
Aside from Sentomaru, I genuinely believe that Vegapunk might be his dad and NO they don't need to look alike.
Yeah, hes showing a surprisingly rebellious side here. First Fujitora now him too. Guess you can count Green Bull going into Wano too lol.
Yeah honestly, they both have that sort of dopey, wrinkled look or so. Given who we learned Bonneys father is here, I can see Oda making him be "that guys" son for a parallel there too.
It's gonna end up adding some more insane layers and foreshadowing to Sabaody too potentially!
They don't have to look alike either as you said too ofc, it might deliberate to make us think they're not actually related in the first place. Plus it explains why he gets called Uncle too then potentially.
This is very exciting potentially.
