A vampire ran desperately through the building. He had seen the man in the white coat cut down a group of vampires without effort. The vampire had never imagined a creature of such strength could exist. He cried out as a bayonet slammed into his back, but continued to stagger forward, crying out again as a swarthy man in a black leather bodysuit and dark sunglasses dropped from the roof in front of him, pointing a sword in his face. The vampire started to back away when another bayonet hit him in the back, and he stopped moving anywhere, frozen with the knowledge that he had a monster both in front and behind.
Anderson watched as the vampire stopped moving, still standing in a droopy position. Anderson decided the vampire was as good as finished and directed his attention to the man in black.
"Ay heard that a freak was hangin' around tonight. The Daywalker, am ay right?"
"That's none of your goddamn business, pal."
"Ye're takin' His name in vain, are ye? Well that is quite offensive to me, especially coming from a freak vampire abomination."
"If you're killin' vampires, then we ain't enemies. I am not a goddamn vampire."
Anderson seemed angered by Blade's once again taking his Lord's name in vain, but he softened. Anderson strongly believed in doing God's work, but he wasn't sure Blade really qualified as an insult to God. Blade had been born as he was, a large part of him was still human and he used his power to kill vampires. Grinding his teeth, Anderson stepped back, lowering his bayonets.
"Ye have a point. We will be having a war soon with the Nazis, and I could use someone else who's good at sending vampires to their final resting place. My name is Father Anderson."
Blade nodded, lowering his sword. Anderson then suddenly looked up, readying his bayonets again.
"May I test your abilities? I like to know what any potential ally is made of."
Blade gave a slightly fierce smile, and readied his sword in a samurai stance.
"Sounds cool to me. Bring it, Father!"
Anderson and Blade charged forward, colliding with the vampire from both sides and literally splattering him. Blade staggered back from hitting Anderson, then jumped forward and locked blades with Anderson once more. Anderson forced Blade back and started slashing at high speeds with Blade struggling to defend against the strikes. Anderson then jumped back and flung a barrage of darts at Blade, charging forward and catching Blade by the arm, Blade having just dodged the darts.
Blade dashed at Anderson and started exchanging fast blows with him, the much harder metal of his sword snapping several of Anderson's bayonets only for Anderson to pull out a replacement each time. Blade left a few cuts on Anderson, and then punched Anderson in the face, grinding his teeth in frustration at his lack of success. Anderson then reared up at Blade with six bayonets placed between his fingers, and the two started exchanging blows, but Anderson's bayonets were soon broken, but he then punched Blade, spinning him around, before pulling two more bayonets.
Anderson stabbed Blade through the chest with both bayonets and threw him onto the floor, throwing two more bayonets into him and nailing him to the floor. Anderson then landed on Blade and readied two more bayonets, but jumped away as Blade swung his sword at Anderson. Blade forced his way to his feet, pulling the bayonets out of himself, but was quickly grabbed by Anderson, who cut into Blade's side and punched him in the face. Blade landed back on the floor and raised a gun loaded with silver bullets, shooting at Anderson, who took the bullets in the chest and buckled.
Blade dashed forward to attack Anderson with his sword, but Anderson jumped back up, striking Blade with another bayonet and then flinging it into Blade's neck. Anderson then gripped Blade's arm, pulling the sword from Blade's hand and tossing it aside, holding another bayonet to Blade's neck.
"This'd be curtains if ye were actually a vampire."
Blade glared at Anderson, then nodded, relaxing as Anderson released him.
"Not bad at all, Father."
Blade and Anderson stood in silence for several seconds before Blade said, "You said something about wanting my help killing Nazis?"
Analysis:
Anderson holds the advantage in strength, having the strength to stagger Alucard who was unmoved by a hit from a bazooka rocket, and also in speed as he is able to comfortably dodge bullets and jump halfway up a building when Alucard releases his final restriction. Anderson also outruns Alucard's advancing forces, a feat the Nazi vampires were not capable of. The Nazi vampires could also comfortably dodge bullets. The only other person who was able to outrun Alucard's advancing forces was the Captain. Anderson is also much faster than Yumie who was fast enough to dodge a bullet literally just as it was about to hit her eye.
The advantages held by Blade are the quality of his sword and his comparable or greater skill. His sword being stronger than Anderson's bayonets is balanced out by the fact Anderson has a seemingly limitless number of them, and obviously Blade's gun won't tip the scale. Blade is arguably more skilled, but Anderson is skilled enough to win still with his superior physical power. As a final note, if Anderson had used the Nail of Helena, Blade would have no real answer to Anderson's newfound power, since Monster of God Anderson was comparable in strength to Alucard who can catch anti-aircraft bullets in his teeth and stand completely unmoved by a bazooka and several grenades all at once. In short, Anderson holds a substantial advantage in physical power.
