Disclaimer - I do not own any of the characters mentioned in this story aside from Suicidal who is my original character. Otherwise I would be very, very wealthy.
Just a very rough scene by scene go through from the Avengers movie combined with an OC of mine.
A/N - Hope you enjoy and for more info on Suicidal checkout my story "Red headed stranger". It has also dawned on me that some of my retelling may be inaccurate and not directly in line with the movie but it is a fanfic so lets just role with it. I've also made some of the characters more powerful and closer to their comic book counterparts. Please read and review and especially keen on feedback about my OC character.
The explosion rocked the entire carrier setting alarms off throughout the hellicarrier. Tony, Steve and Thor sprawled out to defend against the oncoming attackers while Black Widow grabbed Bruce and told her to follow her to safety. Sarah stood by Fury and said "Alright chief let's head" but he replied "Jensen, go with Widow and Banner". Sarah replied "But sir you're the director here and it's my job to protect you". Nick took her by the shoulders and said "Look agent Jensen, right now angry man is our priority. If Bruce Banner Hulks out I need you there to hold him off cause you're the only one that can survive against the Hulk". Sarah half smiled and replied "So if the good doctor goes green I'm punching bag and target practice. Gotcha" and went off to follow.
On the lower floors Sarah went ahead with Black Widow and Bruce Banner when another explosion rocked them and sent everyone to the floor. Black Widow was trapped with her leg pinned under a piece of wreckage while Sarah fell down a flight of stairs and Bruce was knocked over and breathing heavily. Black Widow saw him starting to turn green and while trying to get herself from under the wreckage she tried to calm Bruce telling him "Fight it Bruce I know you can" but it was to no avail as his muscles began bulging through his shirt. Sarah walked up to see the events unfolding and was about to run ahead but Widow signalled her to stand back and said to Bruce "We're gonna be okay. Right? I swear on my life I will get you out of this, you will walk away". At that point Bruce turned and growled "Your life" and turned into the Hulk without the slightest bit of restraint".
Black Widow was still struggling to pull her leg out from under the wreckage as the Hulk stood over and she feared for her life but then she heard a woman's voice screaming "Hey mean and green". She turned around and saw Sarah standing with her handgun and shot two bullets at the Hulk who didn't even notice. While Hulk was distracted Sarah ran up the stairs to the overhead platform and looked down at the Hulk roaring at her, then as though without a thought she jumped on off onto the Hulks head grabbing onto his shoulders. While Sarah distracted Hulk, Black Widow managed to get herself free and stand while Hulk pulled Sarah off his head and holding her with one hand screamed at her point blank.
Black Widow pulled out her twin guns and unloaded her bullets at Hulk taking his attention and he dropped Sarah. With her heart pumping overtime and her blood rushing, the adrenaline surge kicked in and she began to transform into Suicidal. She started growing getting taller and stronger with her special customised uniform stretching together. As she grew taller her hair extended out into long crimson locks hanging down around her. Her musculature broadened and grew stronger, her skin hardened to it's near unbreakable resistance and her fingernails extended ripping through her gloves.
With her transformation complete she whistled and called out "Hey green beanz, you recognise me"? The Hulk turned around and she ran forward throwing a flying kick at him that even the Hulk felt. He struck his fist down which she evaded by somersaulting, then as he swung his arm around she leaped over doing an aerial flip over his arm then throwing a punch to his side. Suicidal grinned and said "Gonna have to do better than that" as she squared up against the Hulk, then with unexpected speed he grabbed her before she could notice and slammed her into the ground like a ragdoll then lifted both fists overhead and slammed down shaking the room but Suicidal rolled out of the way. Immediately as she got up the first thing she saw was Hulk's giant foot smashing into her and she flew back through tons of steel ripping through barely recovering but surviving. As she got stood back up she could see Hulk chasing Black Widow but Natasha managed to get away as the Hulk leaped off further into the upper levels of the carrier.
Black Widow composed herself while Suicidal stood up getting her senses back to normal after a severe beatdown by the Hulk and headed towards Natasha to make sure she was alright. As they were face to face Suicidal saw a look of shock on Black Widow's face and immediately turned around with an arrow hitting her in the shoulder. The arrow bounced off but managed to leave a scratch which angered Suicidal realising she could be hurt. She yelled to Black Widow "Stay behind me" and marched onwards towards the attacking Hawkeye who fired another arrow that bounced off her cheek then another arrow that bounced off her chest. As soon as she saw Hawkeye pressing buttons on his bow and charging a different head on his arrow Suicidal ran forth into the exploding arrowhead as Hawkeye ran backwards.
While the smoke cleared Suicidal heard footsteps then felt something bounce off her head. She looked up and saw Hawkeye leaping off her and somersaulting in mid air with his bow drawn. Immediately she caught him by the foot while the arrow shot out at Black Widow who dodged out of the way saving herself, then Suicidal restrained Hawkeye back. Despite her strength she was struggling to hold him as he would not give in so while Natasha came back in Suicidal finally managed to keep him still by holding her nails spread across his face and throat while holding him back with the other arm.
Black Widow approached and cautioned "Careful there Suicidal. We don't want him hurt but we can't take chances with him" and Suicidal replied "No worries my Russian friend, I'll keep your boyfriend good as new". Meanwhile unbeknownst to both women Hawkeye was using his free arm to unlock the bottom of his quiver and pulled out a high voltage arrowhead and drove it into Suicidal's leg. What would normally paralyse a regular person sent a shock through her body sending her back off Hawkeye and while Suicidal recoiled momentarily freeing Hawkeye he kicked Black Widow and turned around aiming his bow at Suicidal.
In the split moment that Suicidal was in pain Hawkeye pressed a button on his bow and pulled out a net arrowhead and shot out an arrow that exploded into a steel mesh net over Suicidal. As he turned around Black Widow was ready to fight and disarmed him immediately. Using her speed and agility she was able to outmanoeuvre Hawkeye and held her own against him. Meanwhile Suicidal tore through the steel net rising up to see black Widow knocking down Hawkeye unconscious. While Black Widow caught her breath Suicidal said "Aaaaw Widow I wanted to punch his lights out". Natasha took no notice of the comment and replied "I'll take care of Barton, you go upstairs. I have a feeling they might need you a lot more than I do.
