Alexander "Lex" Luthor hit the warehouse door running.

His black leather, military steel toe, oil resistant, jungle boots pounded against the pavement, as thighs burned with exertion from his steady pace. Blood dripped down the side of his face from a gash that ran from the middle of his forehead to his left temple, smearing his cheek, forehead, temple, and neck in red and staining his collar with blood. His ribs were broken, as the far too familiar sharp ridges of the broken ribs pressed against his lungs. Dirt, mud, and various other contaminants stained porcelain pale skin.

Lex's form was covered in black form fitting cargo pants, a black v-neck shirt beneath a military army swat vests for men with a waistcoat protective magazine pouch in black, and a black beanie that covered his bald head for protection. The clothes were dusty and covered in grime, blood, and other adulterants from his most recent skirmish with today's adversary. The dark clothing easily allowed him to slip in and out of the shadows that were contained inside the abandoned derelict buildings.

An array of hellish fire in an array of ruby red, bright orange, and dark yellow splashed off the burnt out ruins of what once was a department store, pulling Lex from his ruminations and back to the present. The triumphant howls and crackling of the Baazalanan increased in volume as they followed after Lex's running form. It was all a sport to these particular aliens, which acted more like an animal than humanoid.

From Lex's peripherals was the shadow of a tall, nine foot, humanoid body that was thin as a spindle, with arms and legs jointed in too many places. There was white bone protruding in lumps through flesh, as blue as azure ink. Its neck was no wider than Lex's wrist, its head more akin to a wolf than anything else. The wolf head stretched long and the mouth cut at the corners to fit in more serrated teeth. It's eyes were like the darkest shadow, a void of nothing, just empty and dreary.

Lex cursed under his breath at the sight. With the Baazalanan having caught his scent, it was only a matter of time before other alien species like Craels, Hoahts, Outriders, Chitauri, Leviathans or Chitauri Gorilla's, came about because of the noise the Baazalanan were creating. He could only hope that no demons became attracted to the sounds as well. Lex wasn't sure he had the energy to deal with both species at the same time.

Lex barely paid any attention to the destruction and decimation of life that surrounded him. It went as far as the eye could see, in the once prosperous city. Now, it was nothing but ruins and remnants of what a civilization used to be. Throughout the world it was like this. Quiet and desolate locations that once was full of life. More often than not, in the city ruins, one could easily stumble across some species of alien or demon looking for an easy meal. It was a free for all, now that humanity has been nearly made extinct, and food being sparse.

Partially melted rebar lay contorted amongst crushed concrete, a cage of metal bones, poised to ensnare the impudent in its spiny jagged grasp. Lex stumbled over the debris that were scattered amongst the ruins of decaying buildings and torn asphalts. The opening maws of buildings invited wariness for their darkened and despondent depths. Lex misjudged his steps as he made his way through the oil and waste that was hidden beneath the debris, barely holding onto his balance as he slips and slides through the mess.

Concrete snagged at Lex's shins as his foot plunged through a puddle, that was deeper than he had originally thought. Unaware of the dangers lurking beneath the surface, Lex's leg was caught on a hidden chunk of jagged steel and momentum carried him downward, sending Lex sprawling across the pavement with a thud. His right knee struck the rubble with an echoing crack.

The snarls and growls of the Baazalanan rang in his ears.

Pain blinded him for a brief moment as he attempted to gain his bearings. Lex was panting for breath as he attempted to stand on shaky and weak limbed arms, but could only lay there as he tried to gain his bearings. There was a coppery taste of blood that sat thick and heavy in his mouth and at the back of his throat. He could feel panic creeping up into his mind as he fought to continue to breath against the pressure of his broken ribs. The pain wasn't helping him. He could feel the air cutting off, his throat closing tight.

Darkness threatened to consume him. The menacing and sinister growls and hisses of the Baazalanan rattled in his skull, but it was too close for comfort, and another overwhelming sense of panic trembled through him. Lex fought viciously to keep himself conscious, as the danger neared closer.

"Get your ass moving Luthor!" Lex hoarsely scowled to himself as he forced himself to stand, leaving smears of blood across the surface of the asphalt beneath him. His legs nearly gave out beneath his shaky and weakened body. Booted feet stepped over broken marble and glass that glistened in the dim lighting of a heavy overcast sky, of what used to be a corporate office building. Thick fog obscured anything further than a couple of feet. It's compacted mist hovered just a foot above ground, encasing any who dared to walk through it's hold. There was no sound of life heard for miles, most animals having disappeared into the wild, or been killed off long ago.

Black dots obscured his vision as his eyesight blurred and the world around him spun and swayed beneath his feet. Fear and rage threatened to overcome the genius as another burst of hellish fire sprayed past him, leaving the scent of acrid air behind it. Pieces of stone fell to the floor, rumbling with the sounds of concrete vibrating beneath his feet, as the Baazalanan came ever closer.

Lex barred blood stained teeth in anger and irritation as he move further away from the Baazalanan. He carefully adjusted the grip of his single-shot M203, 40mm grenade launcher that was attached to his M16 assault rifle, that hung from a strap over his shoulder. Holsters for knives and semi-automatics clung to his thighs, lower back, and in his boots holster. His vest contained additional ammunition and grenades for times like this.

Pulling an EMP grenade from one of the pockets in his vest, he pressed the side of the metal circular bomb and tossed it over to the group of Baazalanan. The EMP grenade clattered to the ground, until it rolled to a stop right before the ever approaching horde of Baazalanan. A steady beeping noise, like one might have heard from a timer, raised in volume until it reached its limit and a burst of bluish white light exploded outward in force field that spread outward like a fence, delaying the Baazalanan's ability to move forward momentarily, while trapping them behind the shield. With another square shaped mechanism pulled from the pockets of his cargo pants, Lex pressed a sequence of buttons, before tossing it towards the shield.

The mechanism hit the group with a rattle and then began emitting a high toned frequency that caused the Baazalanan to screech in pain. The noise was at a frequency only animals, such as dogs or wolves could hear, which worked appropriately for an alien species like the Baazalanan.

"Enjoy that you fucking pieces of shit," he growled with a sneer at the alien species continued to howl and screech in pain as the high pitched frequency rose in volume and the EMP shield burned any Baazalanan that attempted to past.

Lex turned on his heel and stalked down the ruined street at a limping, but steady, pace. His steel bluish grey eyes scanned the area as he walked, wary of any surprise attacks, as he made his way back to the current base of the last of humanity.

The Compound

12:00 Hours

Location: Unknown

There hasn't been a chance to see sunsets or sunrises in a very long time, not when the base of the last of humanity was beneath the ground, in a bunker that used to be utilized in World War II. Now, the only safe place to survive was beneath the ground, where the various alien and demonic species couldn't get in. Over the course of the last couple of years, modern utilities and medical facilities had been added to the bunker. Additionally, there was housing units, bathrooms, classrooms, a canteen, an armory, indoor gardens, and labs.

The scientist who survived the initial purge used these labs to create new weapons and various scientific experiments, in an effort to continue the survival of what was left of humanity. One of the current experiments they were working on was attempting to build a machine that would allow them to send someone to the past. It has been a plan they have been working on for nearly a decade, and finally they were nearly finished. It was why Lex and his team (who were killed by the Baazalanan) were out that morning. Lex and his men had finally found their missing piece to the machine.

Lex walked down the narrow hallway of the bunker, by passing various rooms that housed those who have survived the purge so far, and turned left, walking deeper into the complex towards the labs. Very few were allowed past this point. Two armed guards stood at the doorway that led into the basement of the Compound. The two guards saluted Lex as he passed, causing the older man to smirk only when he had passed them, after saluting them in turn. He enjoyed the power he had, and still does, to wield it over the subordinates that had survived the initial attacks.

It was during his second presidential term that Earth had been attacked by aliens from a distant galaxy. The attack had been brutal and fierce. In just three years, half the population had been wiped out. By the seventh year since the attack, almost all of humanity had been killed off as a good source. The supposed Superheroes had done a better job then most at fighting back, but no one had expected other species of aliens to catch wind of Earth being a feeding ground. They never stood a chance.

Lex walked through the double doorway that led into the lab that contained the machine to travel back in time. The piece he had acquired was already in the machine with a small cluster of scientists standing in a huddle as they talked about the results of the machine.

The fifty-year-old scientist and former President of the United States of America's ignored the conversation going on among his team of scientists. Their conversation, a mere distant excited and buzzing noise to the once multi-billionaire, walked slowly around the machine with calculating interest shining in his eyes. After almost seven years, he and his team of scientists had finally succeeded in creating the machine.

The scientists had finally noticed their leader was present. The bravest of the group stepped forward and spoke, "Sir, with the missing piece for the Machine finally in place, we ran diagnostics on it and it came back with outstanding results. We should be able to run an official test on it in another few months."

"I'm afraid that it won't be possible to wait any longer." Lex responded with a sigh. While he may not look like he was fifty-years-old, having not aged a day since his late twenties, he felt his age in his bones. With having gained all his memories back, and that had been a thrilling experience, he had realized that his baldness had come with something else. He had a Regenerative Healing Factor that allowed him to heal from anything, even if there is absolutely nothing remaining of the body. Every injury he sustained would cease; he would be able to reform himself piece by piece. Even critical injuries can be healed in a matter of seconds. He had discovered that complete destruction resulted in complete restoration.

All forms of cellular injuries and disease infection can be healed at a metaphysical level, by rewriting all damage to a mere memory, even if said injuries appeared before the regeneration powers were obtained, such as heredity illnesses and unformed limbs. This, Lex discovered, was due to the cells and telomere lengths not being shortened in any way. Which is the reason why he hasn't aged and why even forms of sustenance intake required is minimal. He discovered that he is now also immune to drugs, disease, and all harmful foreign substances, and will forever be in optimal health and physical prime.

The regeneration also extends to his mental, emotional, spiritual and temporal existence as much as his physical state, rendering all damage to the mind, soul and timeline to be restored to its perfect working state, and blocking one's mind from any attacks or invasive attempts. It was why he was able to get his memories back. Lex's ability had forcefully awoken during the initial attacks, but his aging had stopped early on in his life. He, whenever he reappeared after healing from life threatening injuries, was in different spatial positions upon regeneration, which allowed him to evade any potential jamming into the body.

Lex gave the scientists a look, "Dr. Strange," he began as he faced Dr. Adam Strange, a scientist that had once worked at S.T.A.R Labs before the attacks. "We do not have time to wait. I have been informed by scouts that we have on the surface that a rather large horde of various alien species is coming towards out location." Silence fell in the room as everyone turned to look at their leader. If these aliens found their location, the last of humanity would certainly become extinct. Dr. Strange gave a terse nod to Lex and turned to face his scientists.

"We need to set it up now." Dr. Adam Strange said as everyone in the room began to rush to get the Machine and the other equipment that would monitor the Machine and Lex.

It was because of Lex's regenerative healing factor, as well as the fact that he was a genius, and a multi-billionaire in the past, that made deciding to send him back to the past to save humanity as the best option. Alexander "Lex" Luthor has the greatest chance of succeeding in saving humanity by preparing them for what is to come. Lex found this rather ironic, considering before his memories had been taken from him, he had been a villain of the highest caliber. While he would work to stop humanity from becoming extinct, that didn't mean he wasn't going to take this change to better his past and future.

There were many things he would have changed, Lex mused to himself as he took a seat on the Machine. It was a circular metal shaped platform with a black leather chair, that looked like a dentist chair, with straps that strapped him down so he didn't hurt himself during the process. Surrounding the platform, in what could be considered it's four corners, was four metal pillars with ancient and alien hieroglyphics that would begin to glow blue and connect with each other. The power it was using was an accumulation of electromagnetic energy, the solar power that came from the sun by solar panels they had on the surface, and the Stones of Power, also known as the Stones of Knowledge or simply the Elements.

Once Lex had gotten his memories back, and began planning to going back to the past, he had broken into the Fortress of Solitude, forced Jor-El (an Artificial Intelligence) to tell him how to go back in time, and then stole the Stones of Power as they would be able to get him back to the past. Of course, he only gained the AI's help after promising that he would ensure that he helped Clark when he went back to the past. Lex had planned to help Clark anyways, even before assenting to the AI's demands, as Lex wanted to ensure Clark's loyalty to him this time around.

Once upon a time, he and Clark could have been something great together. There was a point, before everything happened, that they could have had a chance to be together as a couple. However, the constant lies and distrust between them had been a continuous a mark against them. Especially once Clark began to believe Lionel over Lex. That was something that Lex couldn't forgive Clark for. Not when Clark had heard the stories about the abuse he was put through by his father, and at times his mother. His parents had been the reason why his older sister had run away from home when she was fifteen-years-old, compared to his five years of age at the time. Once they had disowned her, it was like she never even existed.

Lex kept his muscles loose as the Machine began to hum to life. It was understood by everyone in the room that the Machine was going to be extremely painful as it forced Lex into his basic matter and sent him to the past. From what they had discussed with the Artificial Intelligence Jor-El, it would send him to any year in the past he wanted to go back, as long as he was alive in that year.

The Machine continued to hum steadily as the hieroglyphics began to glow a brilliant blue. The light shines brilliantly as the pillars connected together. A blue dome of power covered the platform and made it impossible to see Lex Luthor's sitting form in the middle of it all. The air was heavy with power and magic, making it difficult for those surrounding the platform to breath. The hum grew louder as Lex's screams of pain raised in volume as well.

Chills ran up the watching party's spines at the sound of pure agony. They had all known it would hurt, but seeing how badly it hurt, was a completely different story. They all watched in horror, before having to turn away as the light became too bright for their eyes to handle. The hum and scream of pain reached a crescendo, before silence fell over the room. All those that had been in the room, turned back to see that the Stones of Power and Lex Luthor were gone.

Disclaimer:I do not own anything from the show Smallville. It was created by Alfred Gough and Miles Millar. I do not own anything from the show Buffy the Vampire Slayer or Angel. It was created by Joss Whedon. I also do not own the comic book series from either show. There will be minor crossovers with Charmed, Arrow, Batman, DC Comics, etc.

Author Note: I do apologize if there's any grammatical errors in this chapter. I did go over it a few times, to try and catch any mistakes, but I am only human.

After reading what I had written of this story previously, I have decided I was going to edit previous chapters and completely rewrite the story. This new idea came from reading other fanfiction regarding Smallville Time Travel Fix It stories that caught my interest. However, I wanted to do something a little different than the normal reasons that Lex Luthor would travel back in time. Essentially, the Lex Luthor who travels back in time, is the Lex Luthor who went through the Smallville TV series, but regained his memories after it's ending. With his knowledge of that life, (50 years worth) He decides to rewrite his history for his own benefit, while still working to save humanity. Lex is not a good man, he's a great man with a very morally grey compass.

In this story, Lex has an older sister ten years his senior, and he has four younger siblings. I will be trying to combine Lex's history from both comic book, Smallville verse, and my own personal history, as Lex goes back to his past and changes his life for the better while also preparing for the eventual attack that nearly wiped out humanity. Also, Clark Kent

Excelsior Academy Preparatory School I will have residing in Sunnydale, California. Sunnydale is a very old town, and also will not be a Hellmouth in this story. There is a certain point in BTVS that I will not follow. Now I'm not sure if Excelsior has holiday and summer breaks where the students can leave the school, but for the sake of this story it does.

You'll be seeing some parts from BTVS and Angel in this story. You'll be seeing some parts from BTVS and Angel in this story. While Lex Luthor takes the place of Alexander "Xander" Harris, Alyxandra "Xandra" Harris exists and is six years younger than Lex and the Scooby Gang, making her birthday April 12th, 1986.

Lex Luthor is the half-nephew of Anthony Harris and his wife Jessica Harris. They won't be drunks or abusive, they're be a bit like Lionel, as Anthony was raised like Lionel, as they are half-brothers. However, Lionel's parents are different from the Smallville verse, as obviously Lionel doesn't have a brother in canon. Anthony Harris, like his brother, is a successful business men and competitive by nature.

This story will be an endgame Lex Luthor/Clark Kent pairing, with Lex Luthor/Clara Kent (Clark's "twin" sister), among numerous other relationships that will make an appearance before that relationship occurs. Lex Luthor in this story is bisexual (as I honestly figured in canon Lex was bisexual).
