Thank you to everyone who has favirouted, followed and reviewed this fic so far.

This chapter will begin the final battle of this story, and some League of Legends champions will be brought in.

Power of Magic: Thanks for the review. Well, Doom has done similar things in the comics as well. Oh our heroes are gonna give Doom a fight that he will never forget. You will see as to why Doom is involved.

Super Shadow 2018: Thanks for the review, LOL! I loved that joke. Anti-Monitor won't appear for a while, but I like your suggestion, and I will see if it works in my plans. Agreed, CW Anti-Monitor was pathetic, and hell, even the Ruined King from League of Legends could beat him.

matthorserider40: Thanks for the review. Yes, MCU Peter is absent, but he will show up again at some point.

PotCFan101: Thanks for the reviews. Yep, though Doom is much more powerful and dangerous than even Constantine. I took the scene from 'A Game of Doom', and you should definitely check it out.

SupergodzillaSailorCosmos: Thanks for the review. Yep, that's Doom for you. My faviroute League of Legends champions are Yasuo, Twisted Fate, Gnar, Jhin, Taric, Ashe and Miss Fortune. Buffyverse characters will appear soon in this series.


Chapter 12- Endless combat

Runeterra, Demacia City.

The sound of footsteps echoed as a figure entered a library.

It was a young woman, with long blonde hair flowing behind her. She was garbed in silver armour that clung to her form fittingly, and a staff was in her hand.

She was Luxanna 'Lux' Crownguard, the Lady of Luminosity.

"Where is that spell?" She murmured, taking out a book and flipping its pages.

Just then, the ground shook violently.

Lux turned around in alarm and rushed of the room to a balcony, her eyes glowing. She could clearly see a huge area, the Conqueror's Land, a patch of land centered in the middle of the continent of Valoran.

Many great battles had been fought there in the past, though Lux wondered what was going on now.

"What now?" Lux asked, levitating in the air before flying to the Conqueror's Land to investigate.


Ionia, same time.

A man casually blocked strikes from a ninja while gently sipping a cup of tea.

The man was garbed in a blue cloak, half-shredded, and his long hair was tied in a ponytail behind him. A long sword lay in front of him.

He was Yasuo the Unforgiven.

Sighing, Yasuo casually blocked a strike from the ninja while stirring his tea with a spoon.

He then kicked the ninja's knee, staggering him before hitting him in between the eyes, knocking him out with the spoon as the ninja tumbled back into a pile of other ninjas.

Catching the spoon, Yasuo smirked in satisfaction.

Just then, the ground shook violently, and Yasuo looked around in confusion.

Gently laying his tea on the ground and picking up his sword, Yasuo rushed outside the hut he was in and stared as the world continued shaking violently.

"This must be bad." Yasuo commented. Tying his sword to his hip, Yasuo took off towards the source at blinding speed. A blur was the only trace that he was even there.


Zaun, same time.

A ball hit a wall and bounced back as a long metal arm reached out to grab it.

It was a robot, heavily built with two glowing eyes and a pair of short legs. Huge sheets of metal covered its middle.

He was Blitzcrank the Great Steam Golem.

Just then, the world shook violently, making Blitzcrank look around in confusion as he climbed to his feet.

"WHAT IS GOING ON?" Blitzcrank asked in his mechanical voice.

His senses detected earthquakes coming from central Valoran and a look of determination appeared in his eyes.

"I MUST GET THERE QUICKLY." Blitzcrank said, rushing out of the alleyway.


Bandle City, same time.

Yordles were looking around in confusion as these tremors were affecting even Bandle City, which shocked many Yordles since it existed in the Spirit Realm.

A female Yordle with white hair and large pink ears and goggles on her head hopped down from a tree.

She was Tristana the Yordle Gunner.

"What the hell?" Tristana asked in shock.

"It appears to come from central Valoran." One Yordle said to her.

A look of determination washed over her face as Tristana cocked a huge cannon in her hands and attached several grenades to her belt.

"I'm going to find whatever is causing this and kick its ass!" Tristana growled, hopping through a portal.


The Freljord, same time.

Tremors shook the entire land as entire icebergs cracked and fell apart and even mammoths fell down from the force.

Heavy footsteps crunched on the snow as a man appeared. He was huge, with messy brown hair and a helmet covering his head.

The man was wearing a light tunic which exposed his rippling muscles and two huge hand-axes were in his hands.

He was Olaf the Berserker.

As the tremors increased in power, Olaf threw his head back and let out a loud laugh.

"Finally!" Olaf cheered as the tremors increased. "A proper challenge."

"I thirst for endless combat!" Olaf roared, charging towards the source of the tremors.


Noxus, same time.

A door cracked open as someone entered. The figure stepped into the sunlight, revealing a strikingly beautiful woman.

She had blood red hair that fell down to her lower back. Her piercing green eyes demanded attention and a scar crossed her left eye.

She was wearing skin-tight pants and a pink and white jacket while a pair of long knives were in her hands.

She was Katarina Du Couteau, the Sinister Blade.

"I know you're there, Talon, so you can stop hiding in the shadows like an idiot." Katarina said.

The shadows in a corner shifted and a young man exited. He was garbed in light armour with a cloak made out of blades. A hood covered his face, allowing Katarina to see only the light stubble on his chin.

He was Talon, the Blade's Shadow.

"How did the mission go, sister?" Talon asked.

"Very well, brother," Katarina replied. "Target was eliminated."

Katarina let her eyes wander around the room until her eyes caught a framed panting.

It was of her, Talon and White Canary. The three were laughing about something, and they looked happy.

Katarina's eyes turned wet at seeing that.

"I miss you Sara." She whispered.

Just then, the ground shook violently, and Katarina and Talon looked around in confusion. "What in the Hell?"

"Go!" Talon said to her. "Find out what's causing this and stop it!"

"I will brother." Katarina nodded, kicking the door open and speeding out.

"I've got your back, sister." Talon nodded confidently.


Earth-199999, Avengers Tower, same time.

All of the Avengers from Earth-199999 and Earth-911111, the Earth-21 Justice League, the heroes from Earth-1937, Nimue and Talos stood together as Steve faced them.

"We have one mission," Steve began as all looked at him. "Get Alexia, get her out. Take those Skrulls and Doom down. We are going to show them that they don't control our lives. We do. We are our own people."

Everyone looked at him with determination and nodded.

"Good luck everyone." Steve finished.

"He's really good at that." Talos noted.

"I know, right?" Jason agreed.

And then, Strange chanted before all disappeared in a flash of light.


Everyone reappeared on the Skrull ship just as many Skrull guards noticed them.

Steve threw out his shield which smashed into a Skrull, taking him down before Tony, Tonya and Sam flew into the air, firing repulsors and pistols respectively.

Logan roared and leapt into their midst, stabbing Skrulls left and right with his claws while Chris, Natasha, Bucky and Nikolia fought back-to-back, firing their weapons.

Jason killed one Skrull with a swift stab to the throat while Penny tossed debris at the Skrulls, taking them down and David and John Stewart conjured shields to block.

Several Skrull ships flew outside and Kal, Kara, David and John Stewart flew outside to fight them.

Kal dodged a laser beam and fired Heat Vision that destroyed it.

Then, a thunderclap was heard and Thor flew into one Skrull ship, destroying it before firing lightning that took out several more.

"It is good to see you again, friend." Thor nodded to Kal.

"You too, Thor." Kal agreed, ramming into another ship.

Knight threw out several Batarangs that delivered powerful electric shocks that took down several Skrulls while Wonder Woman rammed into another, taking it down.

Ollie flipped into the air and fired two explosive arrows that knocked out several Skrulls while Nimue decapitated another and Talos shot down some more.


Runeterra, Conqueror's Land, same time.

Yasuo stopped speeding as he arrived at Conqueror's Land. It was a huge patch of green land, with mountains surrounding them and forests darting the area.

But what really caught his attention was the huge Demon army that had gathered downhill.

"Oh boy!" Yasuo muttered, his hand still on his sword.

"Yasuo?" a female voice asked. Yasuo whipped around to see Blitzcrank walking towards him with Tristana on his shoulder.

"Tristana?" Yasuo asked in surprise. "What are you doing here?"

"What are you doing here?" Tristana countered, hefting the cannon onto her shoulder.

"Investigating what's going on." Yasuo replied.

"Then it seems that our interests are aligned." Tristana noted, eyeing the Demon army.

Thundering footsteps were heard as Olaf marched towards the three.

"Olaf, right?" Yasuo asked, remembering White Canary telling him about the Berserker.

"I am. You must be Yasuo." Olaf noted, a grin on his face.

Hearing footsteps, Olaf, Yasuo, Blitzcrank and Tristana looked up to see Lux walking on a ledge.

"Damn!" Lux said.

"Well, well, well," a haughty, female voice said. "If it isn't Yasuo the Fuckhead."

Yasuo had a look of shear annoyance on his face as he turned to face Katarina. "Good day to you, Katarina the Sinister Bitch."

Katarina's eyes screamed bloody murder as she glared at the Unforgiven.

"Oh for crying out loud," Ezreal face-palmed as he arrived. "Can you two please table it until after we beat the Demon army?"

"Ezreal, you know about this?" Yasuo asked him.

"I do," Ezreal said. "Long story short, bad guy named Doctor Doom is the one responsible for summoning that army."

"Then we're gonna take him down." Tristana said with a smirk.

"I thirst for endless combat!" Olaf bellowed.

"Finally, a decent brawl." Katarina added.

Ezreal, Katarina, Yasuo, Tristana, Blitzcrank, Olaf and Lux looked downhill to see thousands and thousands of Demons coming towards them, some normal sized, other giant sized, and several huge 3 headed dog like creatures were there as well.

"Death is like the wind, always by my side." Yasuo said grimly.

"We can do this!" Lux said, looking at them all.

As the Demon army charged at them, the seven smirked at once before Lux, Katarina, Olaf and Yasuo bellowed at once.

"DEMACIA, NOW AND FOREVER!"

"FOR NOXUS!"

"LET THERE BE ENDLESS WAR!"

"SORYE GE TON!"

And then, all seven charged downhill together while the army of Demons charged as well.

Insert 'I Need a Hero' from Shrek 2 here.

Yasuo charged and avoided a ball of energy flung before he threw himself to the ground and slid before moving at super-speed.

Lux flipped and fired a beam of energy at the Demons, incinerating a few while Blitzcrank fired bolts of electricity from his fingers, killing a few Demons.

Tristana rode on his shoulder, firing her huge cannon and killing clumps of Demons like that while lobbing grenades here and there.

Ezreal fired his arcane bow while keeping his distance and Olaf simply leapt with a crazed roar and threw himself into the Demons, beginning to hack away and slaughter Demons.

Katarina charged straight at several Demons and stabbed one before decapitating another from behind.


Earth-199999, Space, same time.

Kal flew into a ship, destroying it while Kara and Thor destroyed some more with Heat Vision and lightning.

Inside the ship, Tony flew and blasted several Skrulls while Penny webbed them up and Jason killed another by ramming him into the ground, breaking his neck.

Bucky fired his gun in a circle, killing several Skrulls before Ollie fired two explosive arrows that threw Skrulls back.

With a roar, Logan stabbed another Skrull through the throat with his claws and sliced down another.

Wonder Woman rammed into a pair of charging Skrulls, taking them down while David formed a large hammer and threw it at the ground, taking down many Skrulls.

Talos killed two other Skrulls and Nimue beheaded another while Chloe took down several more.

"Find Mulan!" Nimue shouted. Logan, Jason, Steve and Natasha managed to break free from the fighting and run towards Talos. "Come on, follow me!"


Paibok and Lyja stood at computer monitors, observing the fighting going on.

"Paibok, we are wasting soldiers trying to kill these fools," Lyja snapped. "We need to retreat."

"No," Paibok shook his head. "We will kill them all. Especially Stark."

"Why Jason?" Lyja asked.

"Jason Stark has served his purpose well but the threat he now poses is too much should our plans go on. I believe we have to remove him from the board." Paibok said.

Lyja frowned uncertainly. "Killing him will be difficult. The man is a master at cheating death."

"None of them will stop us," Paibok hissed. "They are simply pebbles in a huge cosmic game."

Hearing alarms go off, Paibok grinned and said. "Follow me to the prisoner."

He and Lyja walked off at a brisk pace.


Runeterra, Conqueror's Land, same time.

A Griffin charged at Yasuo who side-stepped at superspeed to avoid and sliced it down with his sword before throwing some shurikens which killed more.

A Scythe tried to slice Katarina with its scythe but she leaned back to avoid and stabbed it with a dagger, causing the Scythe to disintegrate into grey mist.

Olaf continued roaring as a hundred large Demons attacked him. He sliced down two with his ax before throwing his second ax which killed a Griffin.

Olaf then grabbed a Demon with his bare hands and ripped it apart before punching, head-butting and smashing Demons.

Lux ran through a dense forest as a large 3 headed dog chased her. Turning back, Lux fired a beam of light that smashed into the creature, sending it flying and destroying several trees.

Tristana blasted a Blue Fang in the face with her cannon, destroying it while Blitzcrank fired electricity from his fingers, destroying some more.

Hopping off, his shoulder, Tristana rolled across the ground and fired at some Demons, destroying them.

"Oh yeah! Once a Bandle Gunner, always a Bandle Gunner!" Tristana cheered.

One Demon leapt at her, but Blitzcrank grabbed the Demon and threw it to a distance. The Demon landed just as a grenade rolled towards it.

With a huff, the grenade exploded, killing the Demon as Tristana and Blitzcrank fist-bumped each other.

Yasuo was chased across the land by a pair of Demons. Yasuo threw shurikens that the Demons avoided before he slid across the ground, damaging it.

As the Demons charged at him again, Yasuo cut the ground with his sword, producing a powerful wind-wall that knocked the Demons out as they crashed against it.

Olaf was growing angrier, giving in to his bloodlust and he kept roaring madly. Head-butting a Blue Fang, he spun and killed two more Demons with his axes.

A feline lunged at him only for Olaf to grab it and rip it in half.

"He really seems to be getting angry." Lux noted as she sprinted across the field towards a group of Demons.

Her eyes glowed golden as she fired a powerful God-Blast, completely annihilating the Demons there while the ground shook violently and trees fell over from the force.

Katarina lunged into a group of Demons and began battling them all, her daggers becoming coated in blood. One Demon knocked her down only for her to stab it in the throat.

Blitzcrank noticed dozens of large Demons charging at him and threw himself down, a protective force field appearing as the Demons attacked.

Tristana stood on top of him and fired her cannon. "Come on you mangy curs!" she roared as she fired at them.

Yasuo noticed and he was surrounded in a blue aura as winds whipped violently around him.

Grinning, Yasuo sped into the Demons, moving like a blur as Demons were cut into pieces.

"Thanks buddy!" Tristana smiled.

"I got your back, sister." Yasuo grinned.

"And I got yours." Tristana nodded back.


Earth-199999, Space, same time.

Thor fired powerful bolts of lightning while Kal destroyed some ships with Heat Vision.

Strange opened a portal inside the ship and Hulk ran out, punching several Skrulls away and ripping more in half.

"Finally, we have a Hulk!" Penny smirked.

Arrows from Tommy and Robin took down several more as Bart, Wally and Pietro sped around, using knives to take down more Skrulls.

A batarang from Knight exploded in a Skrull's face, taking him down as Wonder Woman pushed one back with her shield and sliced him down, while gunshots rang out as Nikolia fired from a corner.


The door to the main headquarters exploded outwards as Jason, Nimue, Logan, Talos, Steve and Ollie ran through.

Several large Skrulls attacked and Logan leapt at them, stabbing one in the throat while Steve bashed another with his shield.

Nimue and Jason sliced down several Skrulls with their swords and Ollie fired two electric arrows that knocked some more out.

"Talos, where is Alexia?" Jason asked.

"Several floors down," Talos replied. "Follow me."'

With that, Jason, Ollie, Logan, Nimue, Talos and Steve continued fighting.


Runeterra, Conqueror's Land, same time.

Yasuo stopped running and sheathed his sword once more. As hundreds of Demons came charging at him, Yasuo unsheathed his sword at super-speed, creating a huge tornado that sent Demons flying off.

Katarina sliced a Demon down before kicking another back while Ezreal teleported about, firing bolts of arcane energy.

Lux charged at a dozen Demons, firing a God-Blast from her eyes that incinerated dozens of them before she turned as Ezreal ducked.

"Don't pretend you didn't see me, Lux," Ezreal smirked. "That doesn't work."

Lux rolled her eyes before blasting some more Demons.

Olaf punched a Demon away as his rage increased. Lifting a boulder with one hand, he hurled it towards a bunch of Demons, taking them down as well.

Tristana ran through some tress, avoiding Demons before she sprinted into the open clearing.

Demons flung balls of red energy at her as Tristana side-stepped to avoid before Lux blasted a Demon, killing it.

Yasuo was knocked back and slid across the ground. He ran at the Demon and chopped it in half before speeding towards a group of Blue Fangs, effortlessly tearing through them.

Katarina threw herself into a group of felines, cutting down many as she turned and head-butted one.

Blitzcrank was swarmed by Demons which tackled him to the ground. Though he kept fighting violently, he was beaten.

Just then, someone tackled the Demons off and began hacking at them with a furious frenzy.

Blitzcrank turned to see that it was Olaf. The Berserker turned and gave him a hand.

"Up, machine. We must wage endless war against these foul creatures." Olaf said to him.

He hauled Blitzcrank to his feet as thousands of Demons surrounded them. Olaf and Blitzcrank looked around before trading nods.

"KILL THEM!" Blitzcrank said.

"WE SHALL END THEM!" Olaf roared as the two hurled themselves into the Demons, hacking, punching and head-butting them into oblivion.

Lux fired a God-Blast at several Demons, destroying them while Tristana blasted some more with her cannon.

Yasuo sped around just as several Blue Fangs charged at him. With a smirk, Yasuo increased his speed level and rammed into the Blue Fangs, effortlessly cutting them down.


Earth-199999, Space, same time.

Hulk thunderclapped several charging Skrulls while Nikolia shot down some more. Bart and Pietro sped around, taking down some more.


"Follow me!" Talos commanded, shooting a Skrull in the head before Jason leapt and kicked another in the chest, sending him flying into a wall.

Ollie fired two explosive arrows before kicking another in a spin motion while Steve bashed another Skrull with his shield and Logan stabbed another with his claws. Nimue decapitated a charging Skrull.

The group ran down some stairs, killing more charging Skrulls while Talos led the way.

As they opened a door, all six of them were blown back by an explosion. As they looked up, they saw Paibok marching towards them, a fierce glare on his face.

"Paibok." Talos snarled, getting to his feet.

"Talos," Paibok sneered. "You are a traitor."

He was about to say more when Jason leapt and smashed a boot into his face, making him stagger back. "Sorry pal, not the first alien I've fought!"

"Fool," Paibok snarled. "You think I'm merely a soldier?" His hand suddenly glowed with energy and he hurled a blast that sent Jason crashing into a wall. "You face Paibok the Power Skrull!"

Talos could only marvel at how the man's ego was even bigger than when they served together as he turned to Jason.

"Prisoner level is two decks down!"

Jason looked at Steve and Logan. "Can you hold him?"

"Go get her!" Logan returned as Paibok roared and lunged at them. Logan blocked with his claws, grunting as he did so.

"Come on, bub." Logan snarled, leaping at Paibok but was grabbed by the throat and thrown into a wall. Paibok turned in time for Steve to ram into him, sending him back.

"I will crush you!"

With that, Paibok unleashed a powerful blast at them, sending Steve back as Logan tired to charge but was sent back as well.


Runeterra, Conqueror's Land, same time.

Katarina lunged at a feline, decapitating it before spinning and throwing another knife that impaled a Demon in the throat.

Olaf howled madly, his roars being heard for miles as he hacked his way through hundreds of Demons.

Blood was seeping from deep gashes in his torso and arms, but Olaf couldn't care less. He loved this. This was the battle he craved.

Nearby, Lux was avoiding balls of energy as she fired a powerful blast from her eyes, destroying the cliff the Demons were standing on and leaving a smoking crater.

Yasuo sped around, before a dozen Demons ganged up on him from the side. Smirking, Yasuo generated a powerful wind-wall that stopped the Demons in their path before he sped into the group, killing all Demons.

"Come and get some, you mangy curs!" Tristana was shouting nearby as she shot down Demons.

As some reached too close, Blitzcrank, who was next to her, lifted her up.

Blitzcrank then fired electricity from his hands, killing the Demons while spinning them both around as Tristana fired and cheered, "Come on! Get some! Get some! Come on! Get some!"

"Thanks for the assist!" She said as the Great Steam Golem put her down.

"WE MUST KEEP FIGHTING." Blitzcrank nodded.

Tristana smirked. "Oh we will."

Ezreal jumped over a log and twisting in the air, fired a bolt of arcane energy that killed a pack of Demons.

Olaf and Katarina then fought back-to-back, killing many Demons that way.

"WHO WANTS TO FIGHT ME!?" Olaf roared.

About a hundred Demons charged at him from all sides. Roaring, Olaf chopped the first two in half before head-butting a third. Smashing a fist into a third, Olaf spun and killed another Demon.

Yasuo ran towards several 3 headed dog-like creatures and leapt, flipping through the air, cut one in half before avoiding the other two as Blitzcrank killed them.

Olaf smashed through another group of Demons, killing them all before Tristana blasted some more.

Katarina stabbed one in the throat and sliced another down before kicking a third Demon in a spin motion.

Lux flew into the air and fired a powerful God-Blast at the ground, and many Demons were killed while the ground exploded.

Yasuo took advantage of the blast to speed in and kill many Demons with swift strikes.

"Send those Demons up!" Lux shouted.

Blitzcrank moved in with Tristana and Katarina, boxing them all in.

With a roar, Olaf charged and punched all the Demons sky-high.

The Demons looked up to see Yasuo hovering in the air, a glare on his face and a hand on his sheathed sword.

"SORYE GE TON!"

With that, Yasuo sped to each Demon, slicing it into pieces as body parts rained on the ground.

Landing on the ground, he walked to where Lux, Olaf, Katarina, Blitzcrank, Tristana and Ezreal were.

Then suddenly an enchanted mist appeared at a nearby tree and turned into Doctor Doom, who looked down at the heroes.

"Doom!" Ezreal shouted as the heroes turned to face him.

"This is Doctor Doom?" Katarina asked.

"Yep." Ezreal replied, glaring at him.

"Why did you attack this place?" Lux asked as the seven walked towards him.

"And you drew that conclusion because I just appeared here?" Doom asked rhetorically.

"Doctor Strange explained about you," Ezreal grunted. "Your plans never work."

"Typical of you, Ezreal the Prodigal Explorer. Assuming you can win every time. But this time, it is much different." Doom said in an emotionless tone.

Olaf roared and leapt at him but Doom did a gesture with his hand and Olaf was sent flying off, shattering the ground on impact.

"Now, let the real game begin." Doom said.


And the first half of the climax is done. Hope all enjoyed it.

So yes, Lux, Yasuo, Katarina, Blitzcrank, Olaf and Tristana have finally appeared! When writing this story, I felt they would be perfect for this fight.

That and Yasuo is my number 1 faviroute League of Legends champion, with Twisted Fate, Gnar, Jhin, Taric and Miss Fortune behind him.

Hope all enjoyed the fight scenes and everyone going all out against the Skrulls.

Next chapter will wrap up the final battle, and the one after that will finish the main story.

Hope everyone enjoyed and see you all next time with another chapter. Stay safe ya all!
