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.
Suicidal ran up the stairs frantically leaping and rushing to the main area of the hellicarrier knowing that not only are they under siege but the Hulk is on the loose and aside from Thor and maybe Iron Man, none else on the ship could survive against the Hulk. As she was making her way up she stopped to see a gun fight between SHIELD soldiers and Loki's invaders. Suicidal knew she had to go after the Hulk but seeing the good soldiers severely outnumbered she couldn't help herself from saving them so she goes in and using her wrist mounted controls she calls in her skyboard.
Looking on the floor she found no shortage of debris and threw a chunk of cement at the oncoming soldiers to get their attention then charged in between the two groups taking gunfire then shouts to the SHIELD soldiers to fall back. The attackers press on shooting multiple rounds of machinegun fire at her but it does no more than annoy the Avenger. She runs at the soldiers catching the first one and tossing them away then comes up to the next and punches him in the face crushing the helmet. As she sees his glowing blue eyes she realises that they are under the same mind control as Clint so she understands that she must take care with them. Within the space of only a few seconds her mind flashes back to her own time under mind control much like these men and women who she is fighting right now and she collapses to the ground groaning. In a few seconds she comes back to her senses from a close range shot from a rife that knocks her over and she rises screaming in furious rage. She catches the rifle and points it up so the next shot misses then pulls the rifle to herself then shoves it into the soldiers face knocking them down.
Another soldier close by reloads a clip into their machine gun and unloads it as Suicidal walks at them again catching the machine gun and crushing it in her grip then punches the soldier in the stomach. Seeing another soldier aiming a rocket launcher at her, Suicidal leaps at them and grabbing him with one arm she throws the soldier over and snaps the rocket launcher in half. Suicidal feels a few bullets hit her in the back then hears a clicking sound and turns around to see an attacker shooting blanks. She turns around and walks towards the frightened soldier who nervously reloads their gun but the closer Suicidal gets the more nervous and clumsily the soldier struggles to reload. As the soldier takes aim Suicidal steps closer and says "I wouldn't do that if I were you" and flashes her nails at the soldier who drops their gun and puts their hands up in surrender
Her wrist unit signals the skyboard coming in and seeing it above her head she picks up the fallen machine gun and leaps onto the board. With Loki's mind controlled soldiers shooting from below she take her machine gun and while flying over she shoots down a glass panel sending them running. She hears a loud crushing noise and turns and seeing Thor flying through a wall then rises almost unphased. Suicidal flies over and hovers nearby Thor and says "Hey tall, blonde and handsome. You need a hand"? Thor replies "Aye fair Maiden. I have faced the frost giants of Jotunheim but this green one is more than a worthy adversary. In days past I would refuse thy help but now it would prove most useful".
Just then the Hulk leaps out into the fight bringing his fist down which Thor catches and counters with a strike to the jaw. Thor yells out "Sarah Jensen, buy me a moments time" and holds out his arm calling Mjolnir to him and Suicidal distracts Hulk by flying past and punching him in the face then just as swiftly flying out. Just before Mjolnir returns to Thor, Hulk manages to get another hit in knocking Thor down unable to grab his hammer. Hulk then tries to lift Thor's hammer but cannot budge it in the least as the floor around him cracks from the pressure, Suicidal flies higher then leaps down crashing into the Hulk like a comet distracting him. Just as Suicidal is about to stand the Hulk lifts her by the hair and growls at her face to face. Suicidal stares back and says "If you want a kiss it's $5 but not tongue. But since you're so big and green then here's a free kiss for you". She wraps her legs around his neck and pounds and his face but after several punches realise she's only making him angry so she opens her hands and rakes her nails at his face repeatedly leaving long bleeding claw marks across his face.
As Hulk raises his hands to cover his face Suicidal leaps off to the ground and calls back her board then jumps back on and hovers back. Before she can catch her breath Hulk uncovers his face which is completely healed within seconds and claps his hands together sending Suicidal flying and her board cracking apart. As Suicidal gets up she looks at her skyboard frowning then turns to Thor who is also standing and charges at the Hulk dodging a strike then jumping on Hulk's back trying to choke him. Suicidal is about to run in but hears a helicopter and turns around to see a gun aimed at the Hulk and she yells "Stop turn back now, you'll only make it worse". The pilot pays no attention and starts shooting then as the bullets draw closer to the Hulk, Suicidal steps in and takes the brunt of the force of te high calibre rounds but after enduring several hits from the Hulk she struggles and collapses while the firing continues and gets to the Hulk. In a fit of rage Hulk throws Thor off and charges towards the Helicopter.
As Hulk gets closer the helicopter stops firing and begins to pull back, then Suicidal gets back up and just as Hulk gets past her she leaps onto his back trying to hold him back but he begins to shake her off. Struggling to keep him still she claws his back but Hulk pays little attention to the ferocious slashing and scratching and reaching over his shoulder he grabs her throwing her into the ground again. She scurries back then leaps onto his face in hope of distracting him from attacking the helicopter but just as she's in mid air he punches her and sends her flying back through reinforced walls with the combination of her unbreakable skin and his strength. Suicidal stands up with her legs shaking and her head buzzing from the last punch. As she inches forward supporting herself against the wall she sees Thor flying towards Loki and Hulk falling after the pilot has ejected. She readies to press her wrist power booster but in her dizziness struggles and begins to collapse not knowing if she had indeed succeeded or failed.
