Chapter 1: The end

After everything thats happened and all she's been through, she wouldn't have thought she would go down this way, being betrayed by those she thought were her friends and comrades, they went and sold her out to the Foundation.

Her AC was banged up, even with all the upgrades she installed that made it slightly more advanced, she was still unable to defeat the horde of drones that seemed endless.

She was currently held up in an abandon factory in the middle of a destroyed town, surrounded on all sides, with no real way of escaping, she was currently outside the AC, its purple and white paint scorched and peeled on every part, she was looking over the damaged done so far, the only reason why the autonomous drones haven't overrun the factory and blown it to kingdom come was due to the dozen or so sentries that she deployed as a distraction by the entrance.

Right now she was trying to weld a gash on the left arm shut with some scrap she found around the factory, her grease covered lilac hair sometimes getting in the way as she welded after fixing the arms she started welling the remaining scrap as improvised armor that would hopefully keep her going a little longer.

When she ended up in this world the first thing she learned was that this world wasn't kind, it was harsh, brutal and it would kill you in seconds if you let it. In order to make it out every day and night you were forced to adapt and keep moving, and when she met the people who she thought were her "friends", helped get her on the right path, taking care of her, acting as a net incase anything happened, and once she got the hang of it and understood how this world worked she knew she had to grow up, the once shy, innocent, selfless person she use to be was replaced by the now cold calculating, battle hardened mercenary who would use any means necessary to survive.

Once she did that they gave her her first AC and she quickly rose through the ranks, become their most valuable member, both feared and respected by the other mercenary groups in this war torn'd world.

But that didn't seem like much now, now the best mercenaries were being hunted down and slaughtered by the reaper squad, making people turn against their best out of paranoia, either telling them to leave, or by killing them out of fear that they would all get killed by the reaper squad if they stayed.

Now the same thing happened to her, her so-called friends asked her to go on mission with them and left her to die.

Even though she was smart and one helluva pilot, she had that gut feeling that she wasn't going to make it out of this one, she still has far too many things to finish, and sadly she felt she would die here.

Her thoughts were interrupted by the sound of something breaking, her lilac eye turned around to see that a group of Ammon drones were pouring into the factory.

She tossed the welder back into one of her cockpits compartments, and initiated start up sequence, hearing the autonomous voice say the same line every time you activated an AC.

MAIN SYSTEM, ACTIVATING COMBAT MODE

She side boosted from her current position to see the spot she was previously at engulfed in a bluish explosion by a Ammon A, she switched her right arms weapon to her battle rifle and destroyed two Ammon A's as they were starting their kamikaze attack.

Witnessing some of their friends get destroyed showed that there were a few Ammon's were S breaking off from the horde of A's to engage from long range with laser fire, as the rest moved in.

She knew that she had to keep moving, so she switched her left weapon to her sentry launcher and deployed three to distract the A drones as she moved to engage the S drones with her battle rifle, dodging their laser fire as she took out all but one drone with her battle rifle.

Before she could Destroy the last one, her AC's proximity alert rung out within the cockpit and before she could turn around she was blindsided by massive mech.

Her AC was sent into machinery, blurring her vision upon impact and dulling her senses.

Once her vision cleared up she looked at her AC's AP which was down 70% of the original amount, she looked to the culprit to find it was a To-605A getting ready to do another charge.

She got her AC up in time to avoid the charge but her left arms forearm was blown off by a Predator that entered through the same way the Ammon's did.

"Well i guess this is the end" She looked to the upper left side of her cockpit to see an ominous red button, she never used it before because it had the potential to kill her, but now that she was about to die, she could at least try to take as many with her as she could.

The predator and the To were right on top of her, saying her prayers she pressed the button, timed seemed to slow as the AC and her body began to feel the changes caused by OP-intensify, seeing a timer show there was only 30 seconds of operational time, she immediately sprung into action.

She side-stepped the predator and To, causing them to crash into each other, and Danced around the swarm of Ammon's as they all followed their programming and charged blindly forward to the still stunned Predator and To causing all of them to blow up.

She jumped towards the last Ammon S that shot her left arm of jumping from pillar to pillar as it tried to fly higher to escape the rampaging AC, but its efforts were in vain as one of its tendrils was grabbed.

She began to spin rapidly before hurling the drone towards the ground and diving on top of it, crushing its body.

When it was finished, OP-intensify operation time ended, she started panting heavily exhausted of energy to the point of fainting she was able to recover and see the damaged she cause, in the middle of the factory she saw the burning pile of scrap that remains of the horde before laughing, which started as a chuckle then going to full blown maniacal laughter.

She did it, she showed those cowards she considered friends that she beat them, she can't wait to see the looks on there faces as she crushes them underneath her AC's foot-

Her thoughts were interrupted again as she heard the sound of a weapon being discharged, quickly moving to the side she saw that a part of the To was still able to function, she pulled out her battle rifle and started to boost towards the remains at a leisurely pace, dodging the occasional round from the barley functioning drone, when he she close to it, she knocked the cannon off and rammed the battle rifle into its one giant red eye before picking it up by the rifle and blasting a hole though it, destroying it.

She was about to start laughing again when she felt an explosion rocked the Factory, The explosion felt too big for any automated weapon to use and not a lot of mercenaries had access to ultimate weapons, thats when she realized that she forgot one little detail.

Looking were the To's round had impacted all her thoughts of living were out the window, the round had hit a massive stockpile of flammable material, in this case fuel tanks, normally this wouldn't be a problem but the fuel was in gas form and the drone she had crushed on the floor was right next to and was on fire, and the icing on the cake is that theres are four tanks that are holding kojima next to the fuel.

The explosion must have been the Round over penetrating the wall and hitting a nearby pile of explosives.

With no real way out in time, she accepted her fate, she wasn't proud oh what she had become or what she did in order to survive here, her eye looked towards a photo sitting on the bottom of the cockpit hud, a picture of her with her older sister and friends all smiling and looking genuinely happy.

"I'm sorry sis, I never got the chance to-" she paused, she had forgotten what she was trying to accomplish what her sister wanted, what her sister wanted her to become its very foggy but it began with becoming something good.

"Well, goodbye..." she said as if talking to her sister, as the factory was engulfed by the combined forces of energy and fire, Time seemed to slow as the fires were just a few inches close to her AC before saying one last word.

"...Neptune"

Then everything went black.

I will post the AC's specs next chapter, But yeah a bit cheesy but hey i'm working on this at 4AM but anyway i will update Peacemaker soon and get going on those other Crossovers

Not sure if I'll add any OCs yet but if you want to suggest anything feel free to do so and as always feedback is appreciated, so don't forget to review Bye!
