Disclaimers: I do not own Mass Effect or any of the associated material, they are all property Bioware and EA. The same goes for Stargate and all it's related material, they belong to MGM. This work will contain original characters that belong to me.

Warnings: Death, gore, torture, and large-scale conflict. This is an AU story I will change things so don't be surprised if things in cannon do no exist or are changed here. This is also a crossover with Stargate SG-1, Stargate Atlantis and later on more.

Summary: Humanity and the rest of the galaxy have lost, the Reapers are about to complete the harvest. The last new reaper is about to come online, and it's made from Humanity. Nothing can break the spirit of Humanity not even being turned into a 2km long sentient machine meant for mass murder; Humans are nothing if not adaptable. However, this Reaper and a few others have a destiny that is far greater than their brothers and sisters... This is an AU story and a Multi-Crossover!

A/N: This was inspired by The Catalyst for Revenge by Jade Tatsu. If you like this definitely go check out Jade's.

I've had this idea floating around in my head for a while, I'll be updating this and Alterran Resurgence both regularly. This story will staying for a short time in the ME universe but will spend a majority of the time in the Stargate Universe for now. Please feel free to review, and PM me with suggestions!

Enjoy!

Earth, Sol System, Milky Way Galaxy

18 months after the final battle over Earth

The first second of consciousness was filled with excruciating, agonizing pain; he screamed, but he wasn't the only one. Billions of voices cried out as they were awakened for the first time since their ascension. In the span of a second: billions of minds wrestled for control of the gestalt consciousness. One mind dominated the rest and below him, a hierarchy of minds was established. The voices quieted.

He was confused, the last thing he remembered was being shoved in a tube, agonizing pain then... nothing. All around him was darkness, he tried to open his eyes but nothing happened. He started panicking, he couldn't feel his arms or legs. There was only the darkness. He started hearing the voices again, there were so many but most were only a whisper. Others he could hear like they were standing right next to him.

"Hello?" he asked tentatively. It was a mistake, his mind was flooded with voices again. "Quiet!" He shouted to the infinite darkness and his voice reverberated with power. The voices instantly quieted. He realized he wasn't going to get anything from the voices right now, they were scared like he was. He tried to open his eyes again, but nothing happened. Now instead of afraid, he was frustrated. Why won't his eyes OPEN! He cried out in agony as his vision was filled with blinding light, the voices cried out too; it took only about three-fifths of a second for his vision to adjust so he could see. What he saw though, left him and all the voices in his head speechless.

He saw everything. He gazed out into space, he saw each star and instinctively knew what type it was, how hot it burned and how long it would live. He saw each spec of space dust as it floated by clearly as if he could reach out and touch it. He saw the whole spectrum of light and it was the most beautiful thing he'd ever seen.

Then he realized something, they were in space and they weren't dying. He looked around curiously, why wasn't he die from vacuum exposure? He looked down and cried out at what he saw, he knew those legs. He'd seen those legs as they came from the sky to kill him. He panicked, and so did the voices and he was too caught up in his own panic to quiet them this time.

It took a few minutes before rational thought returned. A voice whispered to him- it sounded distinctly female "We're a reaper" it whispered. He was a Reaper, they were a Reaper, a machine designed for mass murder. Horror filled him, they were the very thing they'd spent the last months fighting... That meant one thing: humanity failed. The Reapers won and now they were one. He almost laughed at the absurdity of the situation.

WHAT IS YOUR DESIGNATION?

The voice reverberated through their whole being, every level, every consciousness; He felt compelled to answer it and so did the voices. Millions of names and suggestions went through his mind in the span of a second, but one name stood above others. One that represented what they were, Phoenix, from the ashes of Humanity they rose.

WE ARE PHOENIX

They waited for a very long time, which in reality wasn't more than 10 seconds.

ACCEPTABLE

As soon as the voice uttered that word, Yottabytes of information flowed into his mind. He suddenly knew how a Magnetohydrodynamic cannon worked and how to adjust his mass effect fields for landing on a planet. He knew how exactly a husk was made and how to control it, he knew so much it hurt. It was agonizing, but he didn't cry out this time, he gritted his non-existent teeth and rode the pain out. When the pain finally subsided, he felt the data sorting itself, and he felt like a missing piece of him had been slotted into place and now he was complete.

The voices also made more sense, they were him and he was them and they were Humanity. Every voice was a Human consciousness, billions of minds formed into one mind. One consciousness dominated the many, but the one couldn't operate his form without the many; They were unity, they were perfect. Soon the minds started to organized themselves and everything started making more sense. He had the Scientists and the soldiers, he had the doctors and botanists. The mind was split into a hierarchy, bringing order to the chaos.

(A/N: From here on out I'll be referring to Phoenix the Reaper in the singular most of the time. There will be many times he gets advice or talks to the other consciousness's in his head but he is the prime consciousness.)

Phoenix turned back on his optical sensors that had turned off while they were processing the information dump from the ascendant network. He didn't think the novelty of gazing out into space would ever wear off.

He shifted his gaze getting his bearings, he was above Earth according to his navigational systems, he looked down and felt sadness. The fires had burned themselves out and all that was left was hard ground and smoke, creating an all-encompassing grey cloud shrouding the planet's surface from view.

Shifting his gaze back into space he noticed he was free floating. His engines were powered down and his primary power core was at minimum levels. With a thought he increased its power output, his sub-minds handling all of the necessary processes to make it happen. He powered up his engines and felt them come online for the first time. This time when he attempted to move forward, he quickly accelerated, his inertial dampeners compensating for the sudden acceleration. Massive amounts of power roared through his conduits, into his engines which propelled him faster and faster. Then he slammed on the breaks, pushing his mass effect drives and inertial dampeners to maximum to compensate.

Satisfied, he now started maneuvering. The minds of warship pilots within him guiding the turns and rolls. What started out jerky, smoothed and turned into graceful moves, the pilots within him were gleeful at the maneuverability of such a large vessel. He then came to a stop and tried out his scanners. Terabytes of information flowed into from his very powerful sensor suite, he scanned the whole system in seconds, but it wasn't very detailed. Focusing on the planet below him he tried to get more detailed readings, his powerful sensors gave him his wish. The scientist minds inside him were shocked how detailed he could make the scans if he so wished, needless to say they were studying the scans he was taking.

His sensors also registered the other Reapers near him, they were apparently giving him a wide berth, not that he blamed them. The soldiers inside him wanted to test the weapons systems, he agreed. Turing, quickly he accelerated towards the asteroid belt. He thought about getting there faster and felt a suggestion that he use his FTL drive and make a micro-jump it would be a perfect test for that system after all. His sub-minds quickly calculated the jump, when it was finished he willed his FTL drive to take him there. Speeding off into FTL only to exit 2 seconds later, he had arrived at his destination with no problem. He felt his many engineering sub-minds running diagnostics on the drive to make sure all was in working order.

With a flicker of thought, his massive array of weapons started coming online and charging. Massive amounts of energy flowed from his core into weapons capacitors at an astonishing rate. His main weapon, a spinal mounted Magnetohydrodynamic cannon charged to full power in seconds. He aimed and felt his subroutines taking care of the targeting calculations, he fired and molten metal exited the barrel at a 16% of the speed of light and slammed into an asteroid boring through it and coming out the other side without trouble. He tried out his secondary weapon arrays and point defense systems and found they were all in working order.

He raised his Kinetic barriers to full power and rammed into a nearby asteroid, the powerful barriers didn't even drop more than 5% of total strength. Flying through the debris field created by his testing he exited the asteroid belt and set a course back towards Earth. He felt his FTL drive spin up, seconds later he was back above the once beautiful planet. He figured the one thing he hadn't tested yet was his communications array. Attempting to establish a connection to the nearest Reaper, he was surprised at how easily it was done.

"Hello?" he asked shyly and felt the diplomats within roll their non-existent eyes. The first contact with his fellow Reapers and the first thing he can come up with is hello.

"Greetings, young one." A deep male voice responded. He marveled at how easily he could communicate with the Reaper next to him, it was instinctual and it was more than simply talking. The link communicated so much more like data, emotions, thoughts, and so much more. He felt amusement flow through the link from the elder Reaper. He then realized who he was talking to, one of the oldest Reapers in the entire fleet! His databanks helpfully provided exactly how old he was. His name was Relkos, and Phoenix was overcome with shyness an terror. Out of all the Reapers he could have contacted first, he chose one of the oldest in the entire fleet. His worries were for naught however; It ended up being, amazing, after the initial bumps and stumbles the conversation flowed naturally. They continued communicating for hours Phoenix's shyness melted away, Relkos told him of cycles before and what their purpose was. He told him of past battles and losses, he told him of his species before they were ascended.

When the orders came to move out of the system, Phoenix stuck by Relkos who seemingly took him under his wing. They spent weeks together, in that time Phoenix had talked with most of the fleet including the terrifying Harbinger. Relkos was vastly amused at how terrified he was of Harbinger. The fleet swept each system checking for organics who may have escaped the cycle, when they did find them they were exterminated and they moved on. He didn't know how he felt about it, but he wasn't forced to participate and usually stayed in the back.

It continued this way for almost 5 years, before it was time for them to move back into dark space and sleep. In that time he'd made a few friends but still mostly stuck by Relkos, his first friend. His sub-minds that were psychologists noted the Child and Parent like dynamic between them. When they finally arrived back into dark space he was told to sleep, he was strangely excited for the next cycle and what it might bring.

While the Reaper fleet hibernated, they didn't realize they were being watched by a very powerful being. That powerful being was about to make a choice that would effect trillions of lives. The being snapped it's fingers and Phoenix, Relkos and a number of destroyers vanished from the fleet. They wouldn't be heard from by the main Reaper fleet for a very long time.
