Luffy can for sure 1000% beat BM 1VS1
She has nothing over Luffy,
nothing at ALL
she doesnt have
Adv CoA, Future sight or Adv CoC which Luffy has them all beside broken Awakening
Oda pushed Kaido to have a sudden future sight otherwise even Kaido should've been beaten much faster as we saw he wasnt able to defend without FS
