Buffy was looking at Xander, the day after Halloween in the Library. Or rather the large alien made of diamond like material which Xander had turned into using his watch, which was in reality an alien artifact. Which could turn him into aliens, with superpowers. Buffy blinked a few times and say, "What?"

"Seems some how I retained not only many of the memories of Ben Tennyson, Wielder of the Omnitrix... but got some kind of advance version of the Omnitrix." said the crystal man in a deep voice, at the trio collected there.

"Advance version? What makes this... Omnitrix device different from a normal version of the same?" asked Giles, as he was cleaning his glasses.

"It's like someone took the real Omnitrix merged it with the Ultimatrix Evolution features but without the bugs." Seeing the confusions of the people before him, he explained the feature, "It takes a same of a lifeforms DNA, then runs a simulation where the alien is place in a world wide war for millions of year till their DNA begins to evolve the most powerful combat form of that alien. From what I know about it. Which is frightening given some of the aliens in this thing" continued Xander as he finally timed out and return to his human base form.

"How power could a bunch of alien be? Diamond Guy looks good, but little grey men don't look that strong." answered Buffy in a flip manner.

"Celestialsapien for example. I have Ben's memories from when he used his version of it, Alien X, to create a nearly exact copy of hi universe when it was accidently destroyed by the Anihilaarg." The stunned silence was deafening from what was not said and the eyes widing in shock.

"Bloody Hell. You're literal a god. Unlimited ultimate power." The older man looked shocked and scared at the comment.

"Not unlimited. Celestialsapien have two conflicting personas, not including me when I become one, and there has to be agreement before Alien X can do anything. Even walking or talking. If they don't agree, Alien X is basically a statue. Ben knows a way around it, so now do I, but there's a risk I can become a statue for all eternity. So absolute but limited power. A tool of ast resort since so many of the other aliens are more useful.

Of course the next powerful would be Atomix and his power over radiation as well as atomic power. So yeah." continued Xander as he pointed out the powers. The stunned silence continued, so he decided to break the ice.

"I also have monster aliens."

"Monster Aliens, like how is a monster alien different from an alien alien. Couldn't an alien be considered a monster? What would be the difference and why am I babbling." was the rapid responce from the redheaded old friend of the new wielder of the Omnitrix.

"Because they are aliens which seemed based on ghosts, mummies, werewolves, frankensteins and... vampires." continued the dark haired younger man, hoping they would not notice the last part.

"Vampire? Alien Vampire? Mister Kill All Vampires? Burn them with fire? You can turn into an alien Vampire?" asked Buffy as she seemed to be smirking at the new as her shock at the other more powerful alien was lost. Willow was the same, but Giles was still serious.

"Can we see this... alien vampire? I am curious for reference between your new form and the traditional vampire we're familiar with." asked the Watcher, likely diving into his role.

"Okay. But be ready. Vladats have a great hunger for life force energies. Ben was able to control it for the most part, but there was a few slip ups. Especially in the beginning." He moved to his watch and pulled up the holographic interface and selected the alien. Hitting the rised plantform, he said, "Whampire!"

The alien vampire had greenish-white skin and yellow fangs. A black and green jumpsuit, with a broad shoulder chest, black gloves with green fingers with sharp talons, green markings on the back suit and a green spiked mask. His head was large and featured green eyes like all of Xander's forms. His Omnitrix symbol was on the stomach.

He was also drooling.

"So much life force." spoke Xander as he looked at them.

"Xander, don't you dare. We are not twinkies!" said Willow, as she gave her resolve face. Buffy and Giles tensed up, ready for a fight.

"Sorry. It's just my instincts. Like leaving Buffy in a mall with a seventy-five percent off sale." He had to pause for a minute as Buffy went to that mall in her head. Giles stoppped that as he asked for more details.

"I have the power to fly, absorb and feed off the lifeforce of other beings by sucking them, can create a sonic explosion, hung upside down like a bat, see the internal structure of beings and energies of beings, enhanced strength, and become a bat like being. But my greatest powers are my hypnotic eyes and my Corrupturas. " With that he spit out on. A small diamond like thing with horns and bat wings, as well as one eye. He then continued, "A Corruptura can take control of someone who's forehead it's attached to, to control their bodies. Their mind are aware and conscious but completely powerless to stop the control of their bodies. Basically they become my puppets. Also I am immune to all Vladat powers mind control powers."

"Weaknesses?"

"Sunlight, each other, a need to feed, can feed on Ectonurite or ghost aliens, my Corrupturas can break when I time out and they have to attach to work. If you're protected by a shield, like a forcefield or body mucus... it makes you immune. Also if you do enough damage, I can die. Unlike the undead." finished Xander as Whampire as he answered Gile's question.

"Is there anything we can do about... this?" asked Willow, looking worried for Xander. He had also told them before on how people had seen the Omnitrix as a weapon and come after it.

"In all likelihood, no. Chaos magic made the Omnitrix, it may be impossible to unmake it. Assuming it wasn't made because of some greater evil being out there who could only be taken down if Xander has the Omnitrix. Or it could be as simple as having many more opponent for Buffy to train against. With his aliens and powers, Xander should be able to defeat many of the forces of darkness and give Buffy a hard workout. The latter could only increase her power as a Slayer.

The problem is either the world has enemies which could challenge Xander... or it will bring them here to balance it out. In which case, we will need it. My question is what could take on a superhero with powers challenging a god?" answered the librarian, as Xander wished it could as easy as when he hung Spike by his underwear.

In space...

As pyramid ship were preparing for battle on a strange blue-green world, who had tormented and annoyed their gods, others were watching this same world. Strange power readings were coming from their world, more powerful then the technology of the native species. More powerful then the species which was now detecting energy readings, which was why they were moving in secret from their galaxy to this world. Hoping this might have some knowledge which could help some of the major problems they were facing.

The question which was haunting Supreme Commander Thor of the Asgard was, "How to do this without alerting the invading Goa'uld while protecting the Tau'ri and not alerting the Tau'ri more then we have to?"

Author's Note/Commentary:

A few quick things...

If Xander and/or others were to use hybrid costumes which would you like to see him as? Both as gods (Forgotten Realms, D&D, Myths, others) and other media. Like a mix of Lathander and Sune perhaps?

If I were to bring in other god, say because Barren broke the rules to empower others and balance had to be maintained, who would you like to see? Other then Chauntea, goddess of Agriculture, who is Lathander's on/off lover? Cause her I am thinking of mixing with a potential Xander love interest. So the obvious question is who? Cordelia Chase? Or make some kind of Warrior Farm Goddess by using Buffy or Faith?

Based on dogbertcarrol's story, What if Xander dressed as the one boy chosen to fight the darkness, Xander the Vampire Slayer? One question? Does the male slayer in Xander, which will remain in him, and the femae version in Buffy/Faith/Kendra/etc, hate each other or desire each other like mates or both? Also how does the Council react? How big is their mental explosion?

Also on another non-halloween lark...

What about the Xander-Verse, where a renegade power wants to destroy Xander, all Xanders in the Muitiverse. So Xander unite to take them down. Based on Spider-verse.

Or one where the children of every woman Xander was involved with or could be, visits him.
