Giving shanks a scar off-screen means legit nothing
It means nothing since it doesn't fit with your agenda?
How did he do that in the first place?Thats 100% a plothole because even Oda dont know it.Unless you think Shanks didnt counter attack BB for whatever reason
I don't care how he did it. It happened in the story which makes it a canon feat for no DF Teach.
100% not as Ace lags the feats to prove your point.And before you bring it up,the Bouchi Manga is non-canon
Even without that Boichi manga, Ace has canon feats that put him over every single commander. Stalemating Yamato makes him stronger than every YC1 combined. Zoro, King, Marco, Kata, Benn, Shitryu put all of them together and Ace still high diffs them.
Also MF Ace who was tired and nerfed due to seastone was able to nullify Kuzan's fruit. The same kuzan that negs commanders for breakfast with his fruit.
And Yami Teach beat this Ace mid diff.
