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 continued to draw out the chitauri then something came up on her radar as her glasses indicated Iron Man flying past behind her followed by an enormous object. She spoke into her headset "Board: 180" and her board spun around then her heart skipped a beat after what she saw. A giant leviathan like flying ship flew after Iron Man and devastated the pursuing chitauri in its path and continued after Iron Man.
She looked down seeing all of the Avengers including Thor standing below with the giant armoured serpent heading towards them and with a deep breath followed Iron Man. She flew past the serpent noticing how it was carrying an army of chitauri and though they did not attack they were screaming and snarling at her. She wanted to attack as the leviathan came closer to the avengers but knew full well it would be useless and dangerous, and then as she came closer she noticed Bruce Banner standing below. "Oh no, oh no, oh no he's gonna get himself killed" She thought to herself and flew faster hoping to intercept the hit.
As she was speeding down she called into Captain America's earpiece but he was busy talking to Banner. Sarah managed to overhear Captain America saying "Doctor Banner, I think now might be a good time for you to get angry".
Bruce through away his glasses and replied "That's my secret, Cap: I'm always angry" and automatically ripped through his clothes and turned into the gargantuan green Hulk and punched the Leviathan square in the face killing it with one blow.
Suicidal flew on downwards and landed with the avengers and said "So I see the party's carrying on without me". Iron Man hovered down as the chitauri came out in overwhelming numbers surrounding the Avengers. The seven heroes all stood back to back in closed formation and readied themselves. The Hulk let out a massive roar and flexed his enormous muscles, Hawkeye pulled out an arrow preparing his bow and taking aim while Thor raised his hammer ready to strike. Black Widow reloaded her guns, Captain America adjusted his shield to position and next to him Suicidal adjusted her wrist unit to give her an extra power charge up and flexed her hands brandishing her claws. Iron Man charged his repulsors and said "Call it, Captain".
Captain America took charge and called out "All right, listen up! Until we can close that portal up there, what we need is containment. Barton: I want you on that roof, eyes on everything. Call out patterns and strays. Stark: you've got the perimeter. Anything gets more than three blocks out, you turn it back or you turn it to ash. Thor: you've gotta try and bottleneck that portal, slow them down. You've got the lightning - light the bastards up"!
He turned to the two women of the team and continued "Natasha, Jensen. You two and me: we stay here on the ground, keep the fighting here. And Hulk: smash"!
Iron Man took off with Hawkeye dropping him onto a nearby building while Thor flew to the top of the highest skyscraper and unleashed his lightning fury and Hulk leaped into the air smashing into two hovercrafts and annihilating every chitauri in his path. Natasha, Steve and Sarah huddled together as the chitauri closed in and on Steve's mark they attacked. Captain America now on the offensive was utilising his shield masterfully making it bounce off multiple targets knocking each down with a single hit and in the midst of all the combat he even managed to help the local police in their strategy. Natasha was also holding her own with use of her handguns as well as unarmed combat training with the help of her shock gauntlets which let her take down each enemy in close quarters.
Suicidal was for the first time in the fight without her skyboard and would rely strictly on her powers and combat skills. Fortunately she was well versed in the use of her powers and was supercharged from her adrenaline booster while the chitauri were still unaware of her abilities and they fired at her with half the shots missing thanks to her incredible agility while other single shots she shrugged off. One chitauri charged at her and she responded with a backflip kick that sent the chitauri attacker flying. Seeing that firepower was futile a group of a dozen chitauri charged into Sarah bludgeoning her with their weapons and overwhelming her as they attacked.
She began to take the hits drawing them in closer then once she had a chance she went on the offence against the chitauri swarm surrounding her. She began swinging her fists taking them down with her raw power then when she got more space began to use her acrobatics and agility to enhance her fighting and take down larger quantities. Finding one attacking target she caught the attacker lifting it over her head and slamming the alien into the ground, then just as she was ready to deliver the finishing blow she heard a noise behind her.
She turned around and saw three chitauri standing with their guns aimed and in coordinating an attack blasted her and sent her flying several metres across. Slowly recovering, Sarah charged forward and as the three combined blasters began to power up again she leaped forward slashing through the weapons with her claw like nails disarming her attackers then without pause lunged at them throwing one into a building wall while uppercutting the second one and then finished off the third with her claws.
She turned to her two teammates who were discussing the tesseract at the top of Stark Tower and heard Captain America say "Natasha can you take care of the generator" and she replied "Sure. I'll just need a boost". She ran at Captain America who was seated with his shield facing up Natasha jumped onto his shield pushing off into a Chitauri hovercraft taking out the rear guard then taking over the controls aiming for Stark Tower.
Suicidal ran over to Captain America and yelled "Rogers how you holding up"? Steve replied "We've got them on the run but I don't like the look of that" and pointed to a room full of chitauri holding a group of people hostage. Captain America threw his shield at one of the chitauri then as the shield flew he leaped onto a car then bounced off onto a street pole then into the room. Suicidal watched in wonder of his agility and relentlessness and was about to call in her board but instead called out "10 out of 10 Cap. Now let's see if I can wow the judges" and charged into the building jumping one storey up against the wall then climbed up the wall using her nails to dig into the concrete.
When she arrived she was too late for Captain America had taken out the Chitauri and looked at Sarah and said "Next time, try to keep up" but as swiftly as he made his remark his expression turned to horror as his eyes drew to an explosive device. Suicidal and Captain America looked at each other then at the hostages inside and Steve said "We can't save everyone here, hell we can't even save ourselves".
Suicidal said to him "Well guess it's time to live up to my name. Get your red, white and blue arse to safety" and jumped onto the bomb covering it with her body as it ticked away. Steve ran forward wanting to pull her off but the bomb went off and Steve jumped covering himself with his shield as he went out the window. The explosion sent Suicidal flying through the sky and while she only sustained several cuts, her body felt like she got hit by a truck and her head was wringing so she could barely get her bearings right. As she came down, the Stark tech she was wearing activated as her adrenaline skyrocketed and she fell back down crushing the pavement beneath her and slowly getting up.
As she crawled up catching her breath Captain America ran over to help her up and said "That was one crazy stunt you pulled there SJensen. Are you sure you can continue"?
Sarah stood up coming from her knees and replied "Yeah I can go another round. You know the more I slow down the weaker I'll get so bring them on". With the area cleared Suicidal and Captain America ran down the street into another mob of chitauri and as they readied for combat Thor's hammers flew down erupting in lightning sending the chitauri scattering, then Thor flew closer summoning his hammer back and stood by his two teammates.
Captain America came up to Thor and said "Thor you're looking good and strong" and Thor replied "Aye Captain America. I was watching from above and thought you may need thy help".
Captain America replied "Well a helping hand never hurt. Let's go" and watched as another armada of chitauri came at them from land and air.
Just as they were about to attack Suicidal grabbed Steve by the arm and said "Wait, Captain. With Thor here we can spread out. If it's ok I can take another area".
Steve replied "Well with Thor we can take it, but stay close so we can come over your way if there's trouble" and looked over at the Mighty Thor who was deflecting the incoming laser blasts.
Suicidal called in her board and quickly jumped on as it was mid air and screamed back "Thanks Cap. I'm going after Loki".
Captain America yelled "Wait get back here you can't go after him alone. Thor do something"
Thor replied "I say thee nay Captain. That Sarah Jensen has proven herself a fearsome battle maiden and I fear not for her but for my brother who doth stand against her. For now my battle is by your side"
Still concerned Steve asked "But it's Loki, do you honestly think she can take him" and Thor replied "She fought courageously by my side as we battled the green giant. Let her face Loki in battle" then he raised his hammer to the incoming chitauri and bellowed out "HAVE AT THEE"!
