I think BB can still use darkness to render Laws DF useless.U_U.....because BB reaction was enough to scar an on guard Shanks before he had yami yami.
His powers would only render Law unable to use his powers if he grabs Law, and it's not like Law would just do nothing as Teach gets close. Black Vortex can be countered by simply doing an attack before you actually reach Teach, Law can just cut him as Teach pulls him in.
This Shanks feat is starting to irk me on here. People say it like they know for sure when Teach did it. For all we know, it was two days after Shanks left Roger's crew and was still a snot-nose. For all we know, it was two days before Shanks saw Luffy eat the Gomu Gomu no Mi. We know nothing about when or how Teach scarred Shanks, it doesn't hold that much weight to it.
Law is just gonna stay motionless while Teach pulls him in? Okay, if you say so.[/QUOTE]
I kinda agree we dont know much about how Teach scarred Shanks but Teach was threathning enough to make Shanks warn Whitebeard to withdraw Ace from pursuing Teach.
