He should currently be as strong as a Yc3 honestly. I place him at the very same level that sanji was before sanjis new lineage gene's powerup. As hard as that may seem to believe oda is doing several things that suggest he is indeed strong
1. He hyped up the potential capture of boa Hancock. And he futher went out of his way to not show any other combatant on the same ships as coby heading towards her.
2. He has been hyping up Coby's growth rate from jumping to a scrub that can't fight to using cipher techniques in 6months. And now in 2 years he is promoted to marine HQ captain with his post being in the new world under akainu. Akainu love him or hate him he respects the power of competent soldiers in battle.
3. On top of this this dude is now apart of a secret organization in the marine faction that is a polar opposite of cipher pole within that same 2years?????
4. He also allowed coby to take part in guiding and protecting a royal nation to maregious with kyro stating that the dude (coby) is strong and modest.
So Coby is stronger than Drake? Because according to Jack, none of the Tobi roppo, including Drake, are YC3
Alright, so you are specifically banking on Coby, the Luffy fan, Defeating Boa, the other Luffy fan in a pure 1v1 fight… And Oda will have to specifically say “Coby defeated Boa Hancock”… Not “The marines defeated Boa”… No Oda has to specify it was Coby that did it… Since he will obviously not actually show it
Hmm, okay… So you are just WAITING for that Act 3 end for a newspaper to have those exact words and for Boa and Coby being Luffy fans to NOT be a plot point in this situation at all
