In the year 8941, The scientists at MACDUS have created a marvel.
A being, capable of shapeshifting into anything with organic material in it. When it does, it takes memories, skills, powers and magic abilities.
In the year 7045, magic was found when a group of soldiers returned from the cave of Baniik on the planet Shar'zor. They returned with the ability to toss fire, water, life and undead.
The one with powers of fire was capable of surviving in volcanos for as long as they want. These people are usually used to enter planet cores due to their intense tolerance of any temperature.
The one with powers over water were capable of extinguishing fire, making pools of drinkable fresh water and even aggressive sharks leave them alone when they explore deep water areas.
The third with powers of life could heal any wound, disease, sanity issues and control the earth around them in some ways. They couldn't control how fast crops grew or alien plants without extreme training.
The last with powers of death could summon skeletons and zombies to do their bidding for a certain period of time depending on their training. They could temporarily stop people from dying, again the length depends on their training. This form of magic is usually illegal to use because, the more you use it, the more evil and crimes you end up committing. This form of magic is also more potent and addictive to use than other forms.
As time went on, more and more forms of magic were uncovered. Eventually, these were the forms found.
Fire, Water, Wind, Life, Death, Psychic, Ice, Light and Dark.
Each and every form of magic appeared when the wielder matured at the age of 20. There were, however, extremely rare. In the population of 400 billion humans and aliens spanned over the Milky Way, only 500 magic wielders were found.
So, in 8000, the group of MACDUS was formed to create the perfect human. With all forms of known magic, the ability of shapeshifting and free will, it would be the perfect human.
The result: Project E-43.
It took them 941 years, but they did it.
For the next 3 years, Project E-43 was injected with knowledge of everything known to every species of the milky way. Magic, technology, every language, maths, geography, science, art, weapons, fighting and everything else.
In total, it took 944 years and 700 billion Credits, the universal currency, but it was finished.
For the next few months, Project E-43 was processing for the information it was injected with.
Then, in March 17th 8941, Project E-43 was called a success when the single cell of Project E-43 rapidly reproduced and a human was made.
This human opened it's golden eyes and looked around the room it was in. Then, it turned directly to one scientist and changed.
The shape shifter was perfect. His ability to shapeshift worked flawlessly. Down to the atom level, they were the exact same. He had every form of magic, as tested, and was trained as high as possible. He had every skill they pumped into him. Drawing, using weapons, fixing vehicles and weapons, convincing people to do things, no matter how dumb, and the other skills they pumped into him.
And so, Project E-43 was called a full success and the 944 years and 700 trillion credits a good investment and he was moved into the military, reaching the rank of Commander and earning the Star of Terra in months.
Then, in the year 10777, Project E-43 and all the research of him vanished completely. No trace could be found of him or their research. After that, Project E-43 was called a failure and every planet that pumped credits into the project withdrew their support.
Without sufficient funding, MACDUS was disbanded and the country that made them swore not to try to make another perfect human.
Though E-43 vanished because he wanted to.
By shapeshifting into the tech savvy Quarians, Turians and humans, he was able to add their knowledge to his and create a time machine to go back to 2183 to create a new life for himself in the past. Something about the past intrigued him.
The time machine worked, partly. He was sent back in time, and to another universe.
Project E-43 woke in small alleyway. He stood immediately and looked around. This place was not in his memories. He looked out the alleyway and saw a Turian walking past the alley. He shapeshifted instantly and memories rushed him. He looked around the newly named 'Citadel' and changed back into his form, with clothes that matched this year's fashion. He walked out of the alleyway and walked to the left, toward the Embassies. According to the Turian's memories, there was quite a view.
Absent-mindedly playing with fire in the hand hidden beneath his jacket, (Imagine Shepard's uniform you get for importing a ME2 character into ME3, just without the N7 logo) he leant over the railing and looked out. The view was, true to the Turian's memories, beautiful but he'd seen better on the planet of Dagobah. Project E-43 saw a trio of armoured humans, a Quarian and a Krogan head toward Councilor Udina's office. He got off the railing and went behind a pillar, activating the tactical cloak from 10777 and following them.
Project E-43 followed the five through the door as they opened it and went into a corner to eavesdrop on the now seven individuals in the room.
"You're not making my life any easier Shepard. Firefights in the wards, Trashing Chora's Den-" Udina began until he turned around. "What's this? A Quarian? What are you up to Shepard?" E-43 instantly deduced this man as a human extremist and racist.
"This Quarian has evidence against Saren. Which I would have said, had you not jumped down my throat." Shepard stated. Udina's tone did a complete 180. From angry to respectful.
"Really? Maybe you better start at the beginning Miss..." Udina began.
"Tali. My name is Tali'Zorah Nar Rayya." Tali started. "I was on my pilgrimage." E-43 tuned out after that, leaving a small part of his brain to listen for any other important information. It seems even in this alternate universe, Quarian, when they reach maturity, get trained and equipped befoe being sent out to bring something of value to their homeworld of Rannuch.
"Eden Prime was a major victory! The beacon has brought us one step closer to finding the conduit." A Turian's voice projected through Tali's Omni-tool.
"That's Saren's voice! This proves he was involved in the attack!" A black human male cheered.
"Saren won't get out of this one." Shepard growled. E-43 saved this piece of information.
"Wait there's more! Saren wasn't working alone!" Tali quickly replied.
"And one step closer to the return of the Reapers." An Asari voice projected over the speakers.
"I don't recognize the other voice, the one talking about Reapers." Udina scratched his chin.
"Maybe the Council know." Shepard wondered.
"Regardless of what they think of the Reapers, this proves Saren's gone rouge." The unnamed male stated. Then, the group left and, after a quick mind scan, were off to head to a fast travel.
Project E-43 was definitely curious about who 'Saren' was and what the end of this political debate would be. Following the group out the door, he went behind the same pillar and deactivated his tactical cloak, already fully charged for another cloak. He followed Shepard and his group in a different fast travel car, as not to raise suspicion.
Achivement!: BACK TO DE FUTURE! 5G: Well technically, you went back to the past but if you follow the same logic as Back To The Future then you went forward into the past which would make no sense as the past is backwards and the future is forwards and the whole process repeats itself infinitely if you try to explain it like I did.
