Beaten by Blackbeard? Any proof to back that up? It states he was captured by the Blackbeard pirates he probably got low diff'd by the horse
Thing which you can't prove in any way at this point, because we haven't the chapter yet or any complete spoilers.
I said BB because it seems that his commanders were in a difficult position at that time, but even if it was a BBP member, Smoker still lost no diff to Doffy.
Like I said, maybe Koby is weak, maybe no, I don't know, but losing to BB or BBP in any way is underwhelming.
We have to wait for the chapter at least.
