Chapter 18.

Hey everyone. Back with another chapter.

This chapter will cover the final showdown against Nemesis, Typhoid Mary, Saracon and the Klingons. It will also be written entirely in Third Person POV.

It will also end the Discovery arc as well before we move onwards. So yeah this is going to be a long chapter.

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

Disclaimer: I don't own any characters and elements you see in this fic. I only own Jason Stark and any other OC's and worlds you see in this fic.

On with the show.

SupergodzillaSailorCosmos: Thanks for the review. You will find out more about the SCP Foundation Mythos Scarlet King later on. I agree on the He-Man/She-Ra idea but not sure if He-Man will show up. If you have a good idea, feel free to leave it in a review.

the mysterious Mr.E: Thanks for the review. Dude you just read my mind. You will see in Chapter 20 what happens with John Wick.

No One's POV.

Following the defeat of Gabriel Lorca and the return to Earth-1, the Discovery had warped to above Quos, with Leonard Snart, Quinten Beck, Jason Stark, Cassilda, Shang Chi, John Constantine, Frank Castle, A.C, Oliver Queen and Bruce Wayne suiting up to go fight Nemesis, Saracon and Typhoid Mary on the ground. Nick Fury, Maria Hill, Talos, Soren and Monica Rambeau would also provide ariel support.

The Discovery would remain airborne to fight off the Klingons.

The heroes beamed to the ground.

"Let's move" Jason said as they all ran silently across the large field towards a close sector of buildings.

Cassilda and Oliver hid behind several crates as Klingons moved into the filed.

Oliver silently shot both of them down.

Another Klingon patrolled the area but was quickly dispatched by Bruce who had used his suit to blend in with the shadows.

Shang Chi flip-kicked another one that came close by while Jason brutally killed another one.

"Let's go" Jason whispered and together, they ran further into the sector.

It was dead quiet which the heroes all found rather strange.

"There they are! All forces kill them!" a speaker boomed as multiple Klingon warships flew towards the grounded heroes along with hundreds of ground solders.

"Go, we'll handle them" Beck said as his helmet formed over his head.

Beck and Snart then charged to fight the Klingons.

Shang Chi leapt onto a nearby rooftop and sailed across it, dodging gunfire.

Cassilda grabbed a Klingon and threw him so hard; he was knocked out on impact.

Frank drew a large knife and brutally killed another Klingon.

Constantine chanted as a fireball emerged, killing another four.

Jason drew his sword and slashed down two while A.C punched another one down.

Bruce silently knocked out two.

Oliver drew an arrow and it flew into one Klingons throat, killing him.

The heroes all moved forward, killing Klingons left and right.

"Split up guys, we can cover more distance that way!" Jason shouted.

Shang Chi and Cassilda ran down a narrow alleyway while Jason and Oliver teamed up.

Bruce and A.C went together and Constantine went with them.

Frank travelled by himself.

Then a crack of thunder was heard as a being slammed into the ground, creating a massive impact crater.

It was Nemesis.

Her eyes glowed bright purple.

She stood in front of Cassilda and Shang Chi.

The master of Kung Fu got into a fighting stance ready to hold the line if neascary.

Above them, the sounds of gunfire and explosions were heard.

"Shang Chi, go now. I'll hold her off" Cassilda said in a calm voice.

Shang Chi looked reluctant to do so, but he nodded and leapt onto a rooftop, dodging gunfire.

"Oh handle me, that's cute" Nemesis mocked.

Cassilda cracked her neck and charged at Nemesis.

She leapt and punched Nemesis square in the face, although Nemesis caught her next strike, punching her in the gut and kneeing her in the face.

Cassilda staggered back and raised her right foot, blocking a strike from Nemesis.

Cassilda blocked another strike and sent a barrage of powerful punches at Nemesis's body, before brutally upper-cutting her away.

She grabbed Nemesis and punched her, before throwing her onto the ground.

As she charged, Nemesis got back up and grabbed Cassilda by the throat, lifting her up into the air.

Cassilda gasped for air and attempted to gauge Nemesis's eyes out.

She grabbed two of the bone protrusions on Nemesis's back, trying to break them.

She grunted but managed to successfully snap one of the bones as Nemesis howled in pain.

She then brutally threw Cassilda away.

Nemesis snarled and tore the broken protrusion off.

She then ran up to Cassilda and brutally punched her multiple times in the chest, and began draining Cassilda of her life force.

Cassilda gasped and fell to one knee.

She then snarled and knocked Nemesis back, before grabbing her and head-butting her.

Cassilda then collapsed to her knees, exhausted.

Nemesis growled and marched up to Cassilda.

She grabbed a limp Cassilda by the arm and began draining Cassilda's energy.

She then slammed a ball of energy into Cassilda, sending her flying back and knocking her out.

Nemesis smirked and turned around, walking to go find Shang Chi and the other heroes.

Cassilda groaned and got to her feet, glaring at Nemesis.

"NEMESIS!" she roared.

Nemesis turned around with a look of rage and disbelief.

"You have no honour" Cassilda panted out.

Nemesis growled and charged at Cassilda.

She punched Cassilda square in the face.

Cassilda tried to fight back, but she was severely weakened and she barely dodged Nemesis's hits.

Nemesis punched Cassilda into a nearby building, where she spat out blood and rose to her feet.

She charged at Nemesis and threw a punch which she easily dodged.

Nemesis replied by punching Cassilda so hard, her ribs broke.

Cassilda groaned in pain and fell to he knees, allowing Nemesis to kick her in the head.

Cassilda slowly staggered to her feet only to get kicked backwards.

"Oh come on, you can do better than that" Nemesis taunted.

Cassilda split blood from her mouth and rose.

She tried to punch Nemesis, but she grabbed Cassilda and pulled her into a vicious headlock.

Cassilda struggled for a while, trying to break out of the headlock, but found it was near impossible.

She eventually stopped, struggling and she knew what was coming.

Nemesis chuckled darkly.

She then snapped Cassilda's neck, killing her.

She threw Cassilda's body to the ground and leapt into the air, looking for the next hero who was stupid enough to fight her.

Meanwhile, Oliver, Jason, Shang Chi, Bruce and A.C were fighting against multiple Klingons.

A.C pummelled them with his fists while Bruce used his martial arts skills to take them down.

Oliver was busy fighting a Klingon when he heard a bow being drawn back.

Spinning around, he fired off an arrow that completely shattered the arrow that was being fired at him.

Standing atop a roof, Saracon looked on in disbelief.

"Impossible. No one is that good" he commented.

He sailed off the rooftop and landed in front of Oliver.

"Maybe because I'm just that good" Oliver smirked.

The two charged at each other and traded blows, but Saracon held the upper hand and smacked Oliver away with his bow.

A.C and Jason fought back to back against Klingons, but both were sent flying back from a telekinetic shove.

"What the hell?" A.C groaned.

Typhoid Mary landed on the ground and approached them with a smirk.

"I've got her A.C, you and Constantine need to handle those guys" Jason said pointing to about two dozen Klingons that were coming at them at full speed.

Shang Chi landed and kicked Mary forward as Jason also got up.

The two of us began circling Mary.

"Let's finish this already" Mary snapped and attacked Jason at blinding speed.

He barely dodged her hits and replied by smacking her with his bow.

S.W.O.R.D. had managed to destroy multiple Klingon warships but there were at least five dozen more warships inbound.

Oliver was busy fighting Saracon and was trying to evade his hits.

Saracon tried to slash with his sword but Oliver leapt over his head.

"Yoohoo!" Oliver mocked.

"Cut that out!" Saracon roared.

"Not this time" Oliver smirked.

Saracon pulled out a miniature nuclear bomb and threw it at Oliver who flipped and kicked it high into the air, causing it to explode as everyone watched.

Jason and Shang Chi were busy fighting Mary and she had managed to knock Shang Chi down while Jason flip-kicked her.

Mary roared and punched Jason, before slamming his head to the ground multiple times, dazing him.

Jason's wounds then began slowly healing as he smirked.

He then brutally head-butted Mary back.

Frank drew a large gun and roared, firing at Klingons, as he punched one down.

Mary grabbed Jason and hurled him into a wall and he fell down, dazed.

Shang Chi punched Mary in the face and elbowed her in a rotary motion.

Mary blocked his next strike and punched him in the ribs.

Shang Chi jumped and kneed Mary in the face as she blocked and whipped him in the face.

Shang Chi staggered back and leapt, kicking her in the chest.

Mary grabbed Shang Chi and punched him in the face as he fell back.

Jason fired an arrow which hit Mary in the leg causing her to yell in pain.

Shang Chi took that opportunity to slam her head onto his knee, dazing her.

Jason leapt and tried to flip-kick her, but Mary sent him flying off.

She then thunder clapped and Shang Chi went flying into a building, dazed.

Meanwhile A.C, Bruce, Constantine and Frank were struggling to hold there own against the endless amounts of Klingons.

Frank roared and drew a machete, cutting off the head of one Klingons and elbowing another one.

Constantine picked up a fallen Klingon blade and was busy duelling with two of them.

Bruce was dodging and weaving around there attacks, and slashed two down.

A.C punched and kicked Klingons into oblivion.

Oliver and Saracon were still duelling as they fought.

"I'll kill you!" Saracon roared and punched Oliver in the face.

Oliver rolled away and fired 3 explosive arrows that Saracon dodged.

Except for the fourth one which caused Saracon to groan in pain.

His wounds then started healing.

He grabbed Oliver and punched him several times in the face, before throwing him into a wall.

Oliver laughed and fired an arrow that shocked Saracon.

"I hate you!" Saracon snarled.

"Feeling's mutual" Oliver said.

Saracon roared with rage and charged at Oliver, ramming him into the wall.

Oliver leapt into the air and fired an explosive arrow that caused Saracon to bleed.

His wounds started healing as he fired a grenade launcher at Oliver.

The rocket hit Oliver but he started healing as well.

"How?" Saracon asked in shock.

"I had Nick Fury inject me with a super serum. You know I don't want to humiliate you grandpa" Oliver mocked.

Saracon fired 4 arrows but Oliver replied by shooting 6 arrows, the first 4 shattering Saracon's 4 arrows and the final two piercing Saracon in both his shoulders.

Saracon snarled with rage and yanked the arrows out.

"Fight me hand to hand like a man!" he declared.

Oliver threw his bow aside and rushed at Saracon.

Saracon kneed Oliver in the face and threw him aside as his wounds started healing.

Jason and Shang Chi were still struggling to fight Mary as she blocked all of there attacks.

Shang chi tried to kick Mary but was blown aside.

Jason drew a knife and charged, trading brutal blows with Mary.

Mary head-butted him and he back flipped.

Bruce was dispatching the last of the Klingons as A.C threw the final one into a wall, knocking him out.

Constantine imiadetley tensed and started chanting as Nemesis landed on the ground.

A.C charged at her and tackled her.

Nemesis brutally kicked A.C off of her as Bruce threw a Batarang which was slapped aside.

Constantine made a fireball appear and threw it at Nemesis who destroyed it.

"Is that all you've got?" she taunted Constantine.

Frank roared and charged at Nemesis, punching her in the face and was kicked into a wall.

Constantine tried to slash her, but she slammed his head to the ground and knocked him out.

Oliver was still circling around Saracon.

"You're drugs make you weak. Now let's see if you have the actual skills to fight me" Oliver mocked.

Saracon kicked Oliver backwards and he rolled, throwing a flechette that disarmed Saracon of his sword.

Oliver raced forward and caught the sword, slashing Saracon's stomach.

Jason had managed to grab Mary and using all of his strength, slammed her head to the ground, knocking Mary out.

He and Shang Chi then turned there attention to Nemesis who was busy fighting Frank, Bruce and A.C.

Oliver carved out Saracon's stomach and kicked him down.

"What's the matter? Ate too much?" Oliver mocked as Saracon screamed in horror upon noticing his stomach had not regenerated.

"That's why you shouldn't take drugs kids" Oliver mocked.

Saracon tried to get up and as he did, a blur of red lightening sped and grabbed Saracon along with an unconscious Mary and vanished.

Oliver shrugged and turned to face Nemesis.

He fired an explosive arrow which she caught but she screamed as the shrapnel entered her eyes.

She tore them out and they healed.

She then punched Oliver hard, sending him flying.

"Where is Cassilda?" Jason asked.

"I'm sorry Jason. She's dead" Constantine said regretfully as he climbed to his feet.

Jason froze at that which allowed Nemesis to deck him hard.

Nemesis looked around to see that Mary and Saracon were both gone and that the Klingon warships except for one had both been destroyed.

Seeing that the Klingon warship was in orbit, Oliver drew his last arrow and aimed.

He then fired the arrow.

The Klingon warship was in orbit and exploded when the arrow hit it.

"Bullseye" Oliver quipped.

"I shall take my leave but we are not done yet" Nemesis snarled and teleported away.

"What did you mean Cassilda's dead?" Jason demanded.

"I mean she is dead. Nemesis killed her" Constantine said sadly.

Jason looked like he had been punched in the gut.

The battle was over but at a terrible price.

A Few Days Later.

A few days following the battle, there had been a massive celebration.

The Klingon forces across the galaxy had surrendered peacefully following the battle.

S.W.O.R.D. had also departed to investigate a demonic presence elsewhere.

But Jason was still half a mess.

He was still trying to come to terms that she was really gone.

The heroes had all gathered together along with the crew of the Discovery.

Pike was there as well.

"I take it this is goodbye" Pike said with a small smile.

"For now" Jason said.

He then shook Pike's hand as they parted as friends and allies.

"Actually Jason, I was thinking of staying here in the future for a while" Snart spoke up.

Jason looked at him with surprise.

"Really?" he asked.

"Yes. This galaxy needs to be cleaned up and I'm gonna help. Thanks for everything though" Snart replied.

Jason nodded in understanding.

"Well take care though. All of you. Also Captain, I wanted to give you this" Jason said taking a small device out of his pocket.

"What is this?" Pike asked as he accepted it.

"It's an interdimensional extrapolator. I designed it so we can exchange travel and communications between us. So if you need help, just give me a call" Jason said.

"Thank you Jason" Pike replied with a smile.

"Goodbye my friends" Jason said with a soft smile.

He then opened a breach to the Monitor's realm and all the heroes including Oliver, A.C, Bruce and Beck stepped through it and were gone.

When they stepped out on the other side, Mar Novu was standing there looking exhausted.

"Novu. I never thought I'd say this, but it's good to see you" Jason said.

"You too Jason and I am sorry for your loss. My friends, I am Mar Novu aka the Monitor" Novu said with a bow of his head.

Oliver, A.C, Bruce and Beck greeted in return.

Jason then turned to face them.

"Thanks guys. For everything" Jason said gratefully.

"Anytime Jason. Sorry for your loss though. It was still fun" Oliver said.

"I made you guys extrapolators for Earth-21 and Earth-1992. So if either of you need a help, just give me a call" Jason said.

"Will do Jay. Thanks" Oliver said.

Then Oliver did something unexpected; he hugged Jason.

"I'll see you again bro" Oliver said.

A.C shook Jason's hand and patted his shoulder while Bruce shook Jason's hand.

They opened breaches to there respective Earths and departed through them.

Jason had earlier invited Back to join his team and the latter was very grateful for it.

"How's Conrad?" Jason asked.

"Follow me" Novu said and they appeared in a hospital wing where Conrad looked near death.

"I'll handle this mate" Constantine said.

He opened Conrad's mouth and poured a drop of liquid in his mouth.

Within a few seconds, Conrad gasped as he awoke.

"YESSSS!" Jason leapt with joy at seeing his old friend awake once more.

"I saw her" Conrad panted.

"Who?" Novu asked.

"Nora Snow Allen" he replied with a smile before collapsing back onto the bed.

Jason sighed with relief.

A few weeks later and Barry Allen had contacted him and his team to help him fight off an alien race called the Dominators.

Back to war again it seemed.

Five Hundred Light Years From Earth.

At a distant part of the galaxy, a robotic being cackled with laughter.

"Time to show the humans that the future is metal"

"Time for the Age of Ultron"

And Chapter 18 is done. I hope you all enjoyed it.

BOOOM! I bet none of you saw this coming.

So yes, Cassilda is dead. Some of you may be wondering why I killed her off. The answer is that I wanted Jason to have emotional pain and that Cassilda always seemed like the least useful OC I had. So I decided to kill her off in this.

However I won't be like those dumbass Arrowverse and Smallville writers who get rid of a love interest and then have the main character promptly forget about her like 5 seconds later.

I do plan for another love interest and PM me if you want to know who it is.

And now I decided to have Snart stay in the future as I have another plan for him.

And now Ultron is here as well and he will be a major villain in a future Star Trek arc that will draw elements from Star Trek: Picard.

The Oliver Vs Saracon fight was inspired by Aragorn II Elessar's fic Trolling Diaz by the way. However Saracon and Mary aren't dead yet.

And now Conrad is awake again. And the name "Nora Snow Allen" will be explored in Chapter 20.

Now next chapter won't begin the Invasion arc, it and the following chapter will be 'break chapters'. Then we will start the first arc centred on Rebecca Potts and Arrowverse Lex Luthor.

Until next time, review, follow, faviroute, stay tuned and tell me what you think of this chapter.
