8 : KRYPTONITE

Tony looked out the window of the living room and saw a sunny day in New York City. The weather was nice. How could his team members hiding in the tower like this?

It's their weekly Wednesday day-off. Steve and Natasha just came back from a mission in Argentina. Thor picked Jane up at the airport last night. Betty and Bruce just came back from their science seminar upstate as well as Pepper just came back from her parent's

The first time in many weeks that they all gathered together.

That it! He gotta do something!

"Avengers Assemble!" Tony shouted. "We going paintball"

Lazy voices came back from everyone and still not move themselves from where they sit. The soldier and the spy didn't even bother to look at the billionaire.

"We need to be more active you brunch of old people!"

"I'll pass, Stark" said Natasha.

"Persuade us, Tony" Steve uttered, "Why should we need to go outside on our day-off?"

Tony grin mischievously and rubbed his hand.


"Damn! How can he do that?" Natasha muttered

"He's good, Natasha"

Steve was sitting in the passenger seat while Natasha was driving her red Ferrari behind Banner's BMW and followed by Thor's Hummer.

"I still can't believe he would be able to persuade us"

"I think it would be fun. Stark even close off the entire arena just for us"

"It's the same as our mission and I think of it as a practice and a chance to kick Stark's ass for good reason"

"I hope that it just a simple game"

"Oh Steve" She laughed. "You don't know a damn thing about paintball yet"

The exciting look on Steve's face suddenly faltered.


Steve step out of the car and he immediately understood what Natasha said to him earlier.

It's not paintball. It's a war. The game of survival

The whole team gathers at the changing room to select their choice of weapon. Stark made a rule that no one allows carrying more than three guns and one grenade. They picked up their color proof suit and a mask

Natasha help Steve with his protection suit before gathered up at the picnic table outside which other girls were sitting

"Tony, please be careful and don't get yourself hurt" Pepper pleaded

"Of course, my dear" Tony said. "But you should tell she devil over there to take it easy on me" The billionaire pointed to the redhead assassin.

"No way, Stark I can only promise hurt and suffer." Natasha replied with her Widow smile.

"How should we play this?" Thor asked.

Natasha and Steve moved closer to each other immediately. Tony saw that and rolled his eyes.

"No No NOOOOO! You two cannot be on the same team. It just not fair!"

"How about we play on our own. Last man standing" Clint proposed.

"Aye!" "Okay then" "Fine with me" "Whatever you say" "Agree"

"May the strongest warrior win this glorious battle! Thou shall lied defeated beneath the Odinson"

"Don't be so sure, Thor" Natasha said.

"Lady Natasha, you cannot match the strength of the son of Odin"

"Care to explain?" The tone of the spy voice changed immediately

But Thor didn't notice that and continued his speech even his friends signaled him to stop. Natasha folded her arms and stared at Thor angrily.

"You're small, my lady. In a game of war, you are not the fiercest warrior."

"Thunderer speaks the truth, red. We are a lot bigger than you"

"From statistic, you are likely to get hurt more than anyone" The doctor expressed his concern.

"Who can fight us in the game of man, Tasha?"

Steve sensed that Natasha was about to explode into a fiery rage. He put his hand on her shoulder and said quietly

"Don't worry, I will protect you"

But that was a trigger. Natasha pushed Steve's hand off her shoulder. The spy gave a murderous glare to every man in front of her.

"Well, today i can only promise you guys one thing. I will make sure you are in serious pain that you will regret to be born. I will come up with the most painful way to kill each of you! I don't care how. You will have a bullet in your eyes socket and you better pray I don't have a real bullet!"

Everyone stepped two feet away from Natasha because she already has a gun in her hand. The spy turned to the super soldier who startled and stepped back a bit.

"And you, Captain freaking America, I will make sure you hurt the most!"

She stomped away leaving Steve gulped by her warning. Tony had to push his best friend to move into the arena.

"Why did she have to threaten me like that?" The captain asked with a shaking voice. "I just try to help"

"Capsicle, you know she hate it when someone think that she cannot fend for herself and you offer to protect her!"


Six Avengers are at their starting point, away from one another, and waited for the signal. Steve saw determination on his friends' face.

But he didn't feel the same because he got threaten by the world deadliest assassin.

The signal sounded and the game has started. Steve pulled his mask down and released the safety on his gun. He ran to find the cover.

Bullet flew around the arena. Even Steve had been through many battles but nothing like this one at all. No battle is more ferocious like when Avengers battled one another and one of them was an angry assassin.

"STARKKK! YOU CANNOT HIDE FROM ME! I'M GONNA KILL YOU!" The furious voice of Natasha came from another side of the battleground.

Steve decided to peek over his cover and saw no one near him. He stealthily moved to find a higher ground. Natasha's voice can still be heard.

"COME BACK HERE IRON ASS!"

"Bruce! Thor! Help me! Do something!" The billionaire cried. "Bruce Bro! Unleash the HULLLLKKKKK!"

The sound of bullets made impact at someone followed by a painful scream and the happy laughter.

No one heard from Tony Stark again.

Steve swallowed because he knew his fate already. If Tony were in that much pain, the thing Natasha will do to him would be hundred time painful.

Captain America ran behind the pine line until clashed with someone. He aimed at the figure and it was Thor.

"Don't shoot me, friend Steven" Thor said. "I been chase by Lady Widow"

"We need to collaborate, Thor. If we want to survive or else Natasha would brutally kill us all"

"Aye!"

And the two warriors moved to the higher ground and try to come up with a plan to deal with Natasha.


Bruce came out from his cover and dragged Tony who lay on the ground, groaning, to the cover. The billionaire covered by multi-color bullet. Natasha didn't hold back and steal Tony's bullet to refill her guns.

"Are you ok, Tony?"

Painfully groan was the answer. Tony tried to sit up and leaned against wooden cover.

"Red is freaking brutal." Iron man muttered. "She shot my ass!"

Bruce tried really hard not to laugh at the billionaire. Tony try using his hand to wipe the paint out of his goggle.

"On the bright side, she took you out first. Imagine what Steve had been threaten"

"Yeah" Tony nodded in agreement. "Romanogers battle each other should be quite an entertainment"

The two geniuses didn't even know that the beautiful assassin standing behind them with a grenade.

"You two make it too easy for me"

Tony gasped and Bruce looked like he about to faint. The redhead devil showed no mercy and dropped a grenade in her hand.

"Leave the arena now, Stark." She said.

The grenade exploded leaving a purple Bruce and Tony Stark who look like cover in mud because he has too many color on him.

Both of then walked toward the exit and drop their crippled body on the ground and lying there.


Thor and Steve taught it was the best way for them if they let Natasha and Clint killed each other first but Natasha was far cleverer than that. She knew Clint would have hide somewhere up above those trees. It's no chance for her to get near him because he has better line of sight

But she is faster and smarter.

The spy knew the location of Steve and Thor as well as Clint. She just waited for the right time.

The silent fall before the forest, Steve and Thor decided to step out of their cover. Right then Steve knew he had made a mistake. Thor got shot by Clint and Clint fell from the tree by a shot from Natasha.

Steve wanted to help Thor but the thunder god signaled him to run. Steve ran for the cover because he knew Natasha could suddenly appear from nowhere.

Thor and Clint were groaning painfully on the ground. The archer cried because he fell from the tree. Thor shot Clint angrily but the two stopped when they saw the spy standing above them with a devilish smile.

"So, who want to die first?"

The two men swallowed and waited for the pain that about to begin.


The painful screams can be heard again. It's even made Steve fear more and more. There are only Natasha and Steve left in this game.

The only way for him to win is to wait until she came out or fight with her hand to hand.

"You cannot run away from me, Steve" her voice came from behind.

She jumped on him and used her legs to wrap around his necks and pulled him to the ground by just one move. The spy straddled on his waist and bend down until her face was hovering above his. Steve gasped. He didn't know what to do because his eyes met with her beautiful green orbs.

Steve froze in the spot.

"Surrender?" The soft whispered lingering at his ear.

Steve shook his head adamantly. His courage will not weaver but Natasha was not any normal woman. Captain America not supposed to have any weakness but he already found his Kryptonite.

Natasha Romanoff is his Kryptonite.

That mischievous grin of her reminded Steve that she's about to do something he never expected.

The spy leaned down and blushed her lips on his for merely two-seconds but it froze the soldier on his spot. When she broke off, she saw a confusing look in his eyes. Natasha bended down near his ear and heard Steve gasped before she whispered.

"Close your eyes, Rogers. It's gonna be hurt"

And the mightiest of them was killed, slowly, painfully by the hands of Natasha Romanoff.


Steve slowly walked to the exit and found out that his friends still laying there. They all looked really in an awful pain. He dropped his body beside Thor.

Everyone covered in a colorful paint. Tony in mud-like color. Bruce in purple. Clint in blue. Thor in green and Steve Rogers in red.

Natasha walked over the dead body of the fallen soldiers with a victorious smirk on her face.

"Where can we find a girl like this?" Tony muttered before groaned like a baby. Hand clutches his ribs.

"She just cold-bloodily killed us" Clint murmured.

"Lady Natasha is the fiercest warrior indeed." Thor admitted.

"She just mobbed the floor with all of us." Bruce cried.

Only Steve didn't give any comment. He was in too much pain to open his mouth but Natasha did prove to everyone how strong she was.

As much as he knew because he saw her in action for two years and she didn't need any super power. She only used her brain and her skilled to won the battle.

Steve couldn't be more proud of his partner.

The girls saw that only Natasha walked out the exit gate. They rushed in to find their boyfriends but when they saw the mighty heroes, the girls couldn't help but laughed.

"Tony! You got your ass kicked" Pepper exclaimed.

"Anyone want to play again?"

Steve was still lie on the ground. Natasha helped him up and walked out the arena.

"Remind me not to piss you off ever again" He said quietly. Natasha burst into laughter. "You're a real meaning of Kryptonite."

The statement was true. Natasha was the only one who makes him weak and it's really hard to breathe when she was around.

She giggled and helped Steve get the protection suit out. Tony said that they should head back to the tower, order some pizza and get cozy watching movie.

Steve slept all the way back to the tower and Natasha can't help but smile at the cuteness of her captain.

The six avengers took a shower and left Pepper to order the food.

"Do you have an entire army with you, miss?" The pizza guy asked her.

"The avengers eat a lot" She replied.

That statement changed everything. The pizza guy eagerly took her order and will send everything to the tower within twenty minutes. The Avengers came down stairs and sat themselves in front of the television. Clint and Bobbi sat on the sofa with Bruce and Betty. Tony and Pepper sat on the love seat. Jane sat on Thor's lap on the left. Steve and Natasha sat together in front of the sofa.

Natasha got to pick the movie and she choose 'The Notebook', which sent Tony into the deep trench of sleeping within ten minutes. Steve was eating his pizza until he was full. He leaned back against the sofa and slowly drifted into sleeping until he was sleeping on Natasha's lap.

The other dozed off in the arms of their love one. Natasha turned off the TV and brought a pillow to support Steve's head before moved herself to sleep in his arms. Her head was on his chest and listening to the steady beating of his heart. His body was warm that she doesn't even need a blanket.

She knew that she is safe within his embrace maybe because of what he said in the paintball arena.

'Don't worry. I will protect you'

He will protect her when anybody else tries to harm her. He is on her side even if he has to fight his friends. She didn't mad at him. She just thought that she might going to blush and might do some stupid things so she had to cover it up by put on the mask of the ruthless assassin.

She soon fell asleep in the warm embrace of her captain.
