15. Dante (Dante's Inferno)
Who needs permanent salvation from memories of hellish behavior? This guy! Soul Calibur can solve his problems. Dante went through Hell and back to save his baby girl, and he did it with a mean scythe to boot.
If Dante can make Death look like a straight beeyotch, he can hold his own on the Calibur battlefield. That scythe of his can do plenty of damage and change forms for added destruction.
Make sure Zasalamel gets back in when Dante arrives. These two scythe wielders could fight for hours and we'd enjoy every slashing minute of it. Dante, duck! GUUUUUUUUAHHHH!
