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 chased after the chitauri hovercrafts through the sky in search for Loki then using her glasses she linked into the shield recognition server and matched Loki's description and followed him. She came up behind and as she flew past Hawkeye on a rooftop she saw him fire an arrow into Loki's eye, then just as it approached from the side Loki caught the arrow without paying the slightest attention. As he caught the arrow Sarah saw the opening and using the distraction she flew into his hovercraft and leaped off tackling Loki. Both plummeted down as Suicidal tackled him but none could get manage to attack as both fell onto a rooftop.
As they recovered, Suicidal leaped onto Loki and began to swipe at his face but he pulled out his dagger and deflected her attack as sparks flew when his dagger clashed with her nails. Finding an opening chance Loki threw Suicidal off himself and leaped to his feet dagger in hand and went forth to plunge the dagger into her heart. Suicidal managed to catch his arm and as she held it to protect herself she went for his throat with her spare arm but Loki was swift and managed to catch her. Both stood at a stalemate with Loki's dagger into Suicidal's heart and her claws to his throat.
As they both struggled against each other Suicidal said "Third time around pretty boy. And this time I promise I won't hold back" and pushed on as her nails came closer and closer to slashing his throat.
Loki began to look frightened and weakened from his fight with Thor then suddenly pushed Suicidal away with a surge of strength to her shock and replied "Yes tis our third battle and you still haven't learned that you cannot match my strength" and threw his dagger at Suicidal.
Suicidal attempted to leap out of the way but the dagger caught her across the leg. As she stood up bruised and bloodied Loki pulled out his staff and blasted her off the roof. Loki shook his head and muttered "Filthy wench" and turned away then heard a voice from behind saying "Hey scarface, get back here". He turned around and watched as Suicidal rose up on her skyboard which saved her on her way down.
Loki went back with his staff in hand and screamed out "Why do you bother to fight me human? Do you not realise that I am a god and you are a weak insignificant speck of nothing".
Suicidal breathing heavily from her fall replied "You know something slim, you look weak. No projectile illusions, no mind games. I bet you're good looking brother must've cracked you pretty hard with that hammer of his" and charged into him on her skyboard.
As she came closer about slam into Loki he held up his arm and her board flew over him and began to spin uncontrollably. Loki looked at Suicidal with a stern look and replied "You dare call me weak. I will show you my true power" and motioned his hand to the side and Suicidal went flying into a wall. Loki repeated the motion throwing her around with his mind like a toy slamming her into the floor of the roof then into a wall again and then toyed with her for his amusement sending the her spinning in circles.
Suicidal was struggling to breathe and could not balance but then in the midst of all the flying a realisation hit her. She noticed that Loki's focus was solely on the board and she herself was in no way restrained so as the board began spin she quickly caught a moment and disconnected herself from the foot holds and leaped at Loki kicking him in the chest and sending him tumbling across the roof. Loki held out his arm to summon the board back to hit Suicidal but with a press of a button on her wrist the board switched off and fell.
Loki stood up watching Suicidal come at him with her hands spread out and she said to him "See here's the thing. When I work for Fury he's always like watch the claws agent, careful with those claws Suicidal, you could hurt someone. Well right now, I couldn't care less that I'm gonna make you my personal little scratching pole. Maybe I'll start by adding some symmetry to your face".
Loki held out his staff and replied "Well then, let's see if you can match you're words with you fierceness" and both charged into combat. Suicidal drew in at close range throwing a punch into his face which Loki deflected with his staff and repeated deflecting her kick then threw a backhanded strike against her face sending her back then spun around tripping her onto one knee and punched her in the face.
Loki looked down at her and said "It's truly a shame to destroy one such as magnificent as yourself. Had you not been so strong willed I may have made you my queen" and slammed his staff at Suicidal but she avoided him by barely an inch. While she tried to stand leaning over onto the floor she looked at her wrist and realised she had enough energy to boost for another charge which although wouldn't heal her it would give her energy and strength. Loki came over as she was about to hit the switch and caught her by the arm and said "No, I will not allow that".
He twisted her arm behind her back then in a final attempt she threw her arm over her shoulder with her nails pointed at his face but Loki caught her arm with lightning fast speed. Holding her by both arms he whispered in her ear "Do me one favour before you die. I want to hear you scream in agony."
With both arms twisted behind her with superior strength she heaved forward and kicked back at Loki and then spun around with a hook punch into his jaw and finally finished off with a backflip kick bringing Loki down. As she went over to finish him off, Loki stood up and grabbed Suicidal by the throat lifting her off the ground. She looked down at his wicked smile as he said "Well doesn't this bring back memories. As I recall this is how we first met".
Sarah could feel him crushing her throat and felt helpless against his strength then finally she grabbed his arm and raked her claws into his skin forcing Loki to release her and fall back in pain as she recovered gathering her breath. Loki held onto his bleeding hand while Suicidal caught her breath finally standing up and breathing heavily said "You say you're a god Loki. Then how come you're bleeding"?
Enraged Loki fired a blast at Suicidal which she dodged and rolled across the floor coming within striking distance of Loki. He slammed his staff down at her but Suicidal caught it with one arm then with the other swiped Loki on the side of his chest leaving a bloody trail of claw marks and sent Loki back in pain. Loki grabbed onto his chest cringing in pain and just managed to evade as Suicidal came at him again just missing him and tearing his cape. Loki held his staff by the end and slashed across with the blade in an enormous circle as Suicidal ran at him and just as the staff was about to connect she leaped over and came down scratching Loki on the shoulder.
Loki's snarling face showed his pain but he did not slow down. Standing with his side to Suicidal he rammed the butt end of the staff into her chin and kicked her back. Suicidal resisted with all her strength and charged forward clawing down Loki's chest with one arm sending him to the floor bent over. Sarah turned momentarily at the sound of an explosion but then came back up to Loki from the behind pulling his head back by the chin and holding her nails against his throat.
As she looked down she spoke to him "You say you wanted to make me your queen. I don't know what's worse; you thinking that I would actually like you or that you seriously though that a skinny, creepy guy like you would have a chance in hell with me. All those nightmares, those visions and that hell you put me through. I should just kill you right now but I'm an Avenger. And I won't bring myself to your level".
Loki was trying to speak so Suicidal pulled closer and listened to him say "You speak of hell. Yet you know nothing of it. But I have already seen hell first hand". And suddenly Suicidal felt something grab her from behind. She looked down and saw Loki fade away with an evil grin and realised he used an illusion to trick her and now she struggled as he held her with the staff at her throat choking her.
As she struggled Loki said to her "I tire of you wench. See you in the afterlife". As he proceeded to choke her she began raking her nails into his leg but he did not give in and held tight. Desperately she continued and then repeating with her other arm was too much for Loki and he let go. Just as she pulled away and turned around Loki struck her across the stomach with the blade of his staff dropping her to the ground bleeding.
He looked down paying no attention to his wounds and said "Well you claim to be invincible. Yet how is it you bleed" and slashed again aiming his blade to her throat with his blade as she fell back lifting her arms in defence feeling the blade cut across her arms. She yelled out in pain seeing the blood coming out of her arms and stood up and turned around to run but before she could run she felt Loki's blade down her back and collapsed bleeding.
As she crawled to her skyboard Loki grabbed her by her hair and dragged her across the ground screaming "You dare humiliate Loki with your filthy claws. You challenged me knowing this would be the outcome, for not even your hardened skin could withstand my blade".
Loki lifted her by the hair over the edge of the roof and held his blade against her throat caressing her skin and readied himself to kill her. Just before he drew the killing stroke Loki heard something coming in, then as he turned around and saw Captain America's shield flying into him. The shield strike sent him flying back dropping Suicidal to the ground impacting into the earth. She looked around beginning to feel weaker but would not surrender or give up on her fellow avengers. She looked up to see Loki standing on the roof and with a mighty heave he thrust his spear into the rooftop and sent an energy blast all the way through. The entire corner of the building began to collapse onto Suicidal and she could not escape and braced herself for impact. Bricks, glass and steel fell around her and hit her harmlessly but finally a large piece of the building collapsed on her bringing her down.
As Suicidal lay pinned under the enormous chunk of debris she struggled but could not move it the slightest bit. Loki appeared above her smiling regardless of his wounds and mockingly said to her "You see I know you're weakness. You can withstand almost anything but you're strength is naught. For all you think of yourself so mighty, you truly are pathetic and weak". Suicidal continued to push the construct on top of her but could not move it in the least. As she desperately pounded and clawed at the structure to no avail, Loki held up his staff and sent out a beacon light and screamed "Chitauri warriors. Come to your master and destroy this wench" and leaped onto a passing hovercraft speeding away.
