AN: Originally I was going to use the Enterprise D Refit from the episode 'All Good Things' but then I fell in love with the Prometheus class. To see what the ship looks like Google images 'star trek Promethus class'. It's the ship with the 4 nacells.

ANII: Due to people not knowing what an ascension class looks like, I decided to change the body type of the ship to a Prometheus class. Only it's much bigger then the 415 meters in cannon. The ships details will be explained in the story, but not until chapter 14.

ANIII: I took a little leeway, in adding Commander Data to the crew of the Phoenix. It's fanfiction, so sue me. (Don't, don't really, I have no money.)

Ship Of The Line: Phoenix

Chapter 01

"This is Captain Bryce D Avari calling any ship within range. Does anyone read?" Came the voice of the man standing on the street surrounded by tiny monsters. He had just tapped the com-badge on the left side of his chest and was calling for help. He didn't know how he got to where he was now, the last thing he remembered was being on The Phoenix, then suddenly he found himself on this M class planet, in what appeared to be a non-technologically advanced residential area. The first thing he did was call for the computer to end the holo-deck program. When the computer didn't respond, he tried his com-badge.

"This is Data, Captain, aboard the Phoenix."

"Data, thank god, Where are we?" Avari asked.

"One moment sir." Data responded. Avari could hear the beeping of buttons being pressed, before Data continued. "Sir, these readings are not making much sense, but the ship appears to be in orbit of a pre-warp earth."

"The last thing I remember was being on board the ship, Just leaving Earth. Now somehow, we're in the past. Activate all Prime Directive Protocols."

"Aye sir." Data replied. On the bridge of the Phoenix, Data input a series of commands, activating the ships cloak, and setting all communication bands to narrow beam.

"Prime Directive Protocols are active, Sir."

"Scan for any other Starfleet personnel, and get them off this planet, asap."

"Aye sir." Data manipulated the controls, finding a total of twenty three active com-badges. He also ran a quick scan of the ship.

"Computer, activate the Emergency Command Hologram."

A tall thin man appeared standing in front of the captain's chair, dressed in captain's colours. "What is the nature of the command emergency?"

"The ship appears to be empty, there are twenty three star fleet personnel on the planets surface, and I have go to the transporter room to bring them aboard. We are following Prime Directive Protocols. You have the bridge."

With that, Data hurried to the Turbolift. "Deck Fourteen, Aft."

Captain Avari fired his type-2 phaser at a small snarling creature, knocking it to the ground unconscious. Moments later, a short blonde woman in a yellow and black security uniform ran around the corner of the street, and approached him.

"Thank god, there's someone else here." She said. "I'm Tasha Yar, Security chief of the USS Enterprise."

He looked at her rank markers,and noticed she was wearing an old style uniform. "Nice to meet you, Lieutenant.

"Do you have any idea where we are?" Tasha asked.

"I was told by my first officer, that we are on a pre-warp Earth."

"That's surprising. The last thing I remember was beaming to Vagra II.

"I was on the bridge of my ship."

They began walking, occasionally stunning creatures that charged at them. Avari happened to glance at the window to a car they were walking past, and froze. He had seen his reflection, and his face was not the one he remembered. He looked completely different, and younger. His hair was longer and black, with a different face under it.

"What's the matter, Captain?" Tasha asked, backing up, to look at the window he was staring in.

"This isn't me."

Tasha froze, seeing her own reflection. "Oh my god."

"You too, huh." Avari asked.

"We need to find out what's happened to us." Tasha stated.

"Data to Captain Avari." Came the voice from his com-badge.

"What have you got for me, Data?"

"The transports are in progress, sir. But I feel you should know, My scans have detected a large power source emitting a type of anaphasic energy."

"Which should not be possible on a pre-warp era planet. We'll check it out. Can you beam us to the location of the energy?"

"Aye sir. Two to beam to that location."

The Annular confinement beam surrounded the two Starfleet officers and they were beamed up into the ships pattern buffers, before being redeposited in front of a shop with a large sign, sporting the name 'Ethan's.

"It appears to be a costume shop, sir." Tasha spoke up.

"That it does, Lieutenant. That it does."

"So Data is your first officer?" Tasha asked.

"That he is." Avari answered.

"Unless you have someone who isn't an android named Data, then we're from different periods in time. I was last in 2364, what year is it for you?"

"2422."

Sudden movement drew their attention to two people who had apparently seen them beam in. One may have been a man, but it was hard to tell, because he was wearing a red and gold mechanical suit of some kind, while the woman was all in white with white blonde hair.

"Who are you and where did you come from?" the man asked. It was definitely a man, Avari could tell by the voice, even modulated as it was through the suits speakers. "Uniforms like that, they gotta be military, of some sort."

The blonde stared at them for a moment, before speaking. "They are possessing teenagers, just like us."

"You know what's going on here?" Avari asked. "Who are you?"

"My name is Emma Frost, and this is Tony Stark. As I said, we are possessing teenagers, summoned by magic." She pointed at Avari. "Your hosts is named Alexander Harris, and yours is Buffy Summers."

"Magic isn't real." Tasha stated.

"Oh it very much is my dear, and it's coming from inside." The blonde woman pointed towards the costume shop.

"How do you know all that, anyway?" Tasha asked.

"I'm a telepath."

"Great," Tasha mumbled, "I hate telepaths."

"My suit's scanners identified the energy coming from inside," Tony stated, "It's some kind of chaos magic."

"It must be the anaphasic energy." Avari commented.

"Well well... lookie what we have here." Came a distinctly British voice off to the side. The four gathered people turned to see a platinum blonde haired man accompanied by two adult men with grotesquely disfigured faces, and a number of small snarling creatures.

"If it isn't the slayer, all weak and helpl-"

Spike cut off mid-sentince, as he had to leap aside, to dodge a phaser beam. "What the hell was that?!"

With a soft whine, Tony raised his hands, powering up the repulsors in his suit.

Emma spoke up, "Tony, the small ones are only children possessed by their costumes. Don't hurt them."

"What about the big ones?" He asked.

"Vampires. You can kill them." Emma said, making a big smile cross Tony's face, hidden as it was by the suit.

Hearing this, Avari and Tasha opened fire on the small creatures, their phasers set to stun. The children were all quickly unconscious. Tony fired at the two non-Spike vampires, tossing them backward into the side of the building across the street, giving Bryce and Tasha time to adjust the settings on their phasers. They then fired at the two dazed vampires, turning them to dust.

"Well this isn't very fair." Spike commented, before spinning, and taking off at full speed.

"Leave him, Tony, we need to free the children we are possessing."

Avari turned and tried the door to the shop, which was locked. He stepped back, and adjusted the setting on his phaser, before aiming it at the door and firing, causing the door to disintegrate.

Tony led the way into the shop, Frost, and the two Starfleet officers following, phasers at the ready. The front of the shop was empty, but there was an eerie green glow emitting from under the curtain to the back room. Bryce and Tasha took out their tricorders, scanning for the anaphasic energy.

"It's coming from back there." Avari informed the group. He led the way, glancing between his tricorder, and what was in front of him as he moved. He pulled the curtain aside, to find a man standing before a two- faced bust, with his back to them.

"About time you got here, Ripper." He stated, before turning around. "Oh. You aren't ol' Ripper."

"No, we aren't." Avari stated.

"It's the statue." Tasha said, "It's emitting the anaphasic energy."

"How do we stop this?" Avari asked.

Emma stared at the man for a moment, reading his mind. "Destroy the statue. It'll end the spell.

Avari aimed his phaser at the statue, and fired, causing it to explode, releasing a green wave of energy that flashed outward, causing the two Starfleet officers, and the two comic book characters to collapse to the ground, leaving Ethan free to make a hasty exit.

On board the Phoenix, Data was manipulating the controls of the transporter when the green energy washed over him. Moments later, the transport completed, leaving the officer within to collapse as well. It appeared that she was a doctor, though not one he recognized. Data rushed forward, tapping his com-badge. "Medical emergency in transporter room three."

After getting no response, he quickly scooped the woman up, and headed for sickbay, activating a hologram to run the transporter while he was away.

"Computer, activate the EMH." Data ordered, upon arrival in sickbay.

"Please state the nature of the medical emergency." Said the hologram.

Data lie the unconscious Trill woman on the bio-bed, before speaking to the EMH. "She is unconscious. I suspect others are as well."

The doctor hologram scanned the trill woman, making sure both she and the symbiont were in good health.

"She's going to be fine." The hologram said, "Just low on energy, and needs rest." He continued to scan her for a moment longer, "Her brain waves are a bit more active then is usual, I'd like to keep her for observation overnight."

"I brought a total of twenty-one officers and enlisted on board. She may not be the only one unconscious."

"I will go with you to check on them." Replied the EMH.

Xander opened his eyes, to find himself lying on the floor in the back room of the costume shop where he bought his star trek costume. Lying with him were Buffy, Cordelia, and a guy in an Iron Man costume.

"Hey. Hey Buff, Cordy. Wake up."

Buffy groaned, and opened her eyes. "Captain?" She asked, sounding confused. "I mean... I mean, Xander."

"Yeah, that's me." He muttered, thinking back to his possession. In his brain was the entire life of Bryce Avari, from growing up in Florida, to serving on the Phoenix. "I think."

He slowly climbed to his feet, and noticed there was a phaser lying on the floor by where he fell. He picked it up, and adjusted the setting back to stun, before realizing that it was a plastic prop when he bought it, but it was now real. He quickly slipped it into the holster on his waist, then moved to help Buffy to her feet. He turned to help Cordelia, and noticed that she sat with her hands on her head, looking confused.

"You alright, Cordy?" He asked.

"What?" She wondered, looking up at him. "Um, I think something is wrong."

"Everything is wrong about tonight." Buffy commented.

"I guess that means I'm not the only one who kept all their costume's memories." Xander stated.

"That's not all I kept." Cordelia commented, pointing at her head.

"You mean Emma's telepathy?" He asked. Cordy just nodded.

Suddenly, The other boy in the Iron Man costume sat up and looked around. "Huh." The mask sprang upward, revealing a face that was about the same age as Xander and the two girls. "My suit is real."

"We need to talk to Giles." Buffy declared.

"I have a van not too far from here. I parked by 'The Bronze'." Said the guy in the Iron man costume.

"Aren't you the guitarist for Dingos ate my Baby?" Xander asked.

"Yeah, I'm Oz."

"Oh, I'm Xander. This is Buffy and Cordelia."

Together, they walked the few blocks to the industrial district of Sunnydale, where the Bronze was located. In the Alley that contained the doors to the stage, sat Oz's van. They climbed in, the springs squeaking when Oz did, which made Xander speak up.

"That suit must be real."

"It is," Oz replied. "I've got a heads up display and an AI, and everything. Say Hello, Jarvis."

"Hello everyone." Said a cultured sounding British voice.

On the way to the school, they explained the truth to Oz about what goes bump in the night. They soon arrived at Sunnydale high, and headed to the library, which was unfortunately empty.

"Where could he be?" Buffy wondered, aloud.

"Um... he didn't by chance... dress up, did he?" Xander asked.

"Um... maybe?" Buffy commented, "I think that Mrs. Calender mentioned about getting them costumes."

"They weren't by chance wearing star trek costumes, were they?"

"I think so." Buffy admitted.

"Great." Xander muttered. "Do you remember what Avari's command was to Data, when they spoke? To beam all the Starfleet personnel aboard."

"You think the ship is still there?" Buffy asked.

"Only one way to find out." He tapped his com-badge, which beeped. "Avari to Data."

"Data here, sir." He replied. Xander released a breath he didn't know he was holding.

"Is everything alright up there?"

"Affirmative, sir. Everyone that I beamed aboard lost consciousness at the same time, but they are all coming around unharmed."

"Good to hear. Are you near the transporters?"

"No sir, but I activated the holographic crewman, so you can call for beam up if needed."

"Good. Where is everyone located?"

"In the Hub, sir."

"Alright, Data, Avari out."

"What's the Hub?" Buffy asked.

"It's the bar and lounge, The hub of entertainment, hence the name. Like on the Enterprise it's Ten forward, on the Phoenix, it's The Hub." Xander double tapped his badge. "Phoenix, four to beam up."
