the only stuff that is hard to counter is the 2nd line but wtv , u're weak , and u're weak cause u dont have hatred ^^Ace couldnot beat BB.
sabo got no chance. If u think Sabo can beat BB just because he had haki then also u are wrong.
BB is a D.Sabo was born in noble family.Most of them fear D. so yeah i think BB had an upper hand there.
He also got WB powers and he must have learned haki now.
