Alucard vs Kenpachi
the immortal vampire against the one who never falls.
monster against monster.
both of them are allowed all of their powers. that means Alucard is at level 0 and Kenpachi has his eyepatch off and is using both of his hands to swing his sword (have a feeling he's going to need it).
who will be standing in the end?
Alucard can be hurt by holy energy. I'd assume that's what energy it is that soul reapers use being as they are the guardians of the entrance into heaven/hell. With kenpachi being the strongest of them, and one of the fastest as well (although he rarely uses it, he's been shown to be as fast as any of the other captains), I dont see how someone who's only strong enough to rip a human apart could hurt him.
