Buffy and new person in town start off on the wrong foot. Buffy's dislike grows over time but not everyone agrees. Starts around Real Me/Replacement Season 5

Buffy is patrolling in the cemetery, it's been a pretty slow night until she hears a distressy female voice cry out. The slayer heads toward the sound and sees a pretty blonde about her age being chased by a brown haired guy in all dark cloths.

The girl has a lead on him but he's fast. Buffy starts running to cut him off, neither of them have seen Buffy yet. He hurtles a headstone and Buffy pushes for a little extra speed. Right before Buffy is going to tackle him he sees her coming and tries to slow down and go evasive. Buffy slides taking his legs out from under him.

He flips forward landing hard on his back but immediately kips up to his feet but Buffy is already standing and attacks with a kick to the head from his right and a left hook. He manages to block both and counters with a spin-kick that Buffy easily ducks. The girl he'd been chasing never slowed down.

Buffy gets her first good look at him, not as tall as Xander and younger, or had been younger when he stopped being human.

Buffy kicks him in the chest trying to knock him backwards into a headstone but he reaches back gripping the stone and stopping his momentum. He ducked her next kick which shatters the concrete planter atop the tombstone. He launches a flurry of strikes partially catching across the side of the head with an elbow.

Buffy stops his attack by kicking the back of his knee and putting him on the defensive. She pulls a stake and brings it overhead and down but he blocks her forearm with his own before she can generate much momentum. There is a confused look on his face and Buffy lands a snap kick to his ribs. He spins away and pulls a wooden stake from his own belt, holding it where Buffy will see it.

He nods at her stake "Is that some kind of sick trophy?" His voice has a little bit of an accent.

Buffy ignores the weird vampire's question and tries a few more kicks before realizing he was keeping her at a distance to use his reach advantage. They mostly block each other's next few kicks but Buffy does draw blood from his shoulder with one swing from her stake. She catches him looking in the direction the girl she'd saved had run off.

"She's safe, I'm going to make sure you never touch her."

"She's probably bringing more of your kind back here. I need to dust you quick bitch."

"You are the weirdest vamp I've ever met. You'll be an interesting story to tell my friends. Then we'll move on."

He steps back looking at her trying to figure something out.

She mocks him "Awe, do you have brain damage? That would be kinda sad with the no soul having."

"You really think I'm a vampire?" He touches the cut on his arm and holds his bloody fingers out. "You haven't fanged out."

"Wow, you really are a… you're still bleeding" she said with surprise.

"Yeah human's do that." He pulls the crucifix necklace he's wearing our from his shirt color.

Buffy holds out her own cross. He angrily demands "What the hell's wrong with you?"

"With me? Who the hell are you, why are you here?"

"I was going to stake that vampire, the one you rescued."

Buffy looks surprised "But, I thought. How was I supposed to know?"

"Next time just stay out of my way."

"Listen kid, I don't know who you are but I protect Sunnydale. Go back where you came from."

"Protect? Anyone that vampire kills is your fault, there blood is on your hands. I'm good at this stay out of the way from now on."

He turns and walks away leaving Buffy fuming.

After a little more patrolling Buffy returns home still angry and tells Giles about the encounter.

"So he seems human? How fast was he moving?" Rupert ask

"Better then track team, maybe vampire or me speed if not then pretty close. Plus he can take a punch and really he's annoying."

Giles sighs "And if sounded like he plans to remain in the area?" he prompts.

"Yeah, he said a couple things like "next time" so yeah definitely sounds like we may be stuck with Mr anti-social mystery guy for a while."

"Well, not to worry, we've dealt with bigger mysteries then this new arrival."
