This time we have another two characters who seem surprisingly similar.
For the east we have a villian from the Metal Gear series, Vamp.
For the west, there's the self-proclaimed "best at what he does", the mutant Wolverine from the Marvel Comics series, X-Men.
In comparing the two, you'll see just how alike they are. Both use blades in battle, both have almost instantaneous healing abilitys, both are more agile and stronger than the average human, and both age extremely slowly.
Vamps healing factor comes from small "robots' in his body called nanomachines, invented by Naiomi Hunter to save him and her from incureable diseses. Vamp is extremely agile, more so than Wolverine and goes about a fight with a level of grace as if a ballet. He has a full collection of knives, daggers, shuriken, and specially designed blades as his weapons.
Wolverine is a mutant, meaning his abilities were given to him at birth. He was born with abnormal strength(though it's not like Superman strength), agility, animal like senses of sight, smell, hearing, and claws of bone that protrudes through his fists. After serving his country, the American government noticed his abilities and used him for a project called "Weapon X". In this project his bones were painfully coated with a layer of a metal called Ademantium, the stronges metal in the Marvel universe.
These two are very similar, but to me personally there is one single difference that makes the choice easy for me. One factor that makes the battle. These two heal at a rapid rate, so the winner would have to make an instantly fatal attack, like cutting the other in half or cutting their head off. For Vamp, it'll be VERY difficult. One word, Adimantium. You cannot cut through adimantium, at all. And the fact that Wolverines claws are coted with adimantim, so I say Wolverine.
