Lol, you think this is weaker than Shanks' attack?
Shanks just caught Kid at the worst moment with his pants down and made his EM attack blow up in his face.

that move didn’t use ACoC and Shanks has some of the strongest haki in the series. It is true Shanks did rebound Kid’s move.
But also, BM had numerous free shots at Kid, who had previously taken damage from Hawkins and Kaido
