In the year 2048 of the Citadel Era, the Turian Hierarchy lost to a newly discovered species called Humans in the First Contact Incident that happened in the Human's newly colonized world, Shanxi. The concepts of war that were observed and used by the Citadel Council and the Galactic Community were shaken the moment the Humans deployed their own brand of weapons, one of them are called the Mechs, a weaponized giant walker that can operate on both planetary surface and space, depending on their specifications. The First Contact Incident (according to the Citadel based Codex) sparked when the 125th patrol, led by General Octavius Oraka of the Turian Hierarchy and his Dreadnaught Talons of the Hierarchy, have fired the first shot when a reconnaissance vessel from the Humans came out from the Relay 314.

When the Turian Hierarchy's pacification fleet entered the Relay 314 to pacify the humans, the battle for Shanxi became the shortest space battle that ever happened when the carrier escorts of the human colony ships, led by Captain Alexander Williams and his flagship, the Noah Class Shirogane Custom, deployed every mech that they have in their hull to outnumber the 55 battleships that the Turians have with their 150 Gespenst Mk11 and Lion Mk14 Armored Troopers, fighters and bombers not included. The mech's general agility and their advanced beam coating that rendered the Turian ship's GARDIAN systems and main cannons useless, combined with the refined beam weapon technology and the recently discovered non-eezo powered FTL drive the humans called the Tesla Drive, have decimated most of the Turian Fleet's ships without any of the Turian ground troopers and drop ships making planet fall.

The human's introduction and entrance to the Citadel general public after the Relay 314 Incident (which the humans did not even qualify nor consider as an incident or a war) has made the Citadel Space become very excited and at the same time, afraid of the newcomers, its brand of technology and its power while highly curious about the newest space flight species that the Turians have found, except for one race.

The Batarian Confederation, a newly established government for the Batarian race after the fall of the Hegemony in the year 2009 CE, made a revelation that they have been in contact with the humans longer than the Turians have. According to Varres Tilak, the current representative of the Batarian race, they met the humans when a Batarian rebel-hijacked derelict cruiser somehow drifted into one of the human held territory after it accidentally activated one of the Relays that the Batarians hid from the Council for "explorations" in the year 1978 CE. When first contact between the Batarians and the Humans are made, the latter agreed on helping the cause of the Batarian Rebels in exchange of information, star maps, and technologies. It is also noted by the ambassador that the humans said that they were the first alien species that did not initiate war or hostilities after fifty five human years of fighting against hostile alien contacts and invaders.

The Turian Councilor and the Salarian Councilor are both angered at the fact that the Batarian Confederation were dealing with the humans for seventy years without even informing them, the latter even more when their STG actually failed to acquire information about the Batarian-Human relationship and the critical information on what truly happened in the Batarian Civil War for long. Batarian Ambassador Tilak added that if the Turian Hierarchy were to declare war to the Humans, the Batarians will also come to aid the humans for they are also humanity's allies that kept them informed of what is truly happening in the Citadel Space.

The Turian Councilor has nearly frothed in rage after the ambassador declared themselves as humanity's allies. The Salarian Councilor's mind went into hyperdrive at the possibilities of the Batarian technologies nearly mirroring the humans. If they were receiving older versions of human technologies, models, and weapons to use and study upon, the Batarian Confederation's research and development made leaps and bounds and they would have begun making customizations and basing newer technologies from the older models. By now, the Batarians are in par with the Salarians and are catching up with the Asari in terms of technological level.

The Asari Councilor however, secretly saw this as another failure that the Citadel has made to their members ever since the Geth Rebellion and the Krogan Hermitage, where the Krogans withdrew from Citadel Membership in order to continue rebuilding Tuchanka and protect their fellow Krogan after their species were afflicted by a disease that causes their reproductive systems to have the lowest fertility rate and highest stillbirth rate that they've contracted from the Rachni. The Batarian Secrecy became popular for hoodwinking the three council races and not realizing that there was a newly found alien race helping the Confederation in coming to power and hidden relays that may have been used by the defunct Batarian Hegemony to enslave pre-space flight races or wage secret wars to technologically disadvantaged space flight races.

When the Turian Councilor suggested that they go to war with the Humans, the Citadel Council has once more seen the true powers of an angry Asari Councilor. She stated that any acts of aggression towards the recently found species have been made into general public and that the Turian Hierarchy will not only be heavily sentenced with years' worth of trade embargos, the Asari Councilor will also ensure that every Citadel Council race civilians will know that the Turians started a war with a new space flight species that was uncalled for and not justified if ever they went to war with the humans.

The Turians will not be seen as peacekeepers but as warmongers the moment they bring their ships to Shanxi. No amount of propaganda will scrub the fact that they will lose their faces across the galaxy if ever a war starts.

The Humans, formally known as the Systems Alliance, however, were also having a serious discussion about their ruse being uncovered when the Relay 314 somehow activated without any ships near it. They know that what is on the other side of the Relay might be a patrol route of the Turian Fleet and that on their side was just a recently established colony world of Shanxi. The only defense that they have there were the 10 ships strong 12th Mobile Carrier Guard Fleet that escorted the colonization ships led by one of the Human's most prized and recently built Capital Ships, the Noah Class Shirogane. Knowing that there will be trouble, the Governor of the Shanxi colony ordered a stealth corvette to scout the opened relay for any potential threats that might be there and depower the Relay after they have finished scouting the area… or warn them of any incoming enemy forces.

Unfortunately, the ship did not come back and in their place, the 125th Turian Patrol. Knowing that ground conflict on a recently established colony with its military garrisons, defenses and installations under construction will be bloody at best, the 12th MCF scrambled all of the fighters, bombers, and mech units and hold the invaders off until reinforcements from either the Alliance or the Confederation arrives. Though the battle was short due to the Shirogane making a quick work on half of the fleet using the Tronium Main Cannon to clear off three fourths of the enemy bulk, the Turians lacking the needed specs to block energy weapons, jammers that are spread by Lions with stealth engines that cut down their communications, and numbers of the mech units that outgunned and outmaneuvered the Turian ships, the Alliance believes that they will not be able to hold their ground against the Turians if they were to invade with a massive number of ships if what the Batarian information has about the Turian Fleet is true, even worse if they brought along the Asari and the Salarians with them.

The best case scenario at that point was that the Turians will not know that one of their patrol fleets went missing.

Luckily, they wouldn't be forced to go to war as the Batarians contacted them and delivered a message that calmed them down.

"The Citadel Council is willing to make amends for what has happened in Shanxi. They are also willing to end any hostilities that may spark between the two races."

The Batarian's message have placated the majority of the human population who are either panicking or in a warpath. It also gave the military and the governing body of humanity the reason to breathe easy, for they will not end up wasting lives, resources, and money over a war that was started because of a relay that suddenly powered up for no reason.

The Batarian ambassador also added a video of an Asari Councilor simultaneously ripping the Turian Councilor a new one for even daring to suggest a war with a newly discovered species that did not even know what the laws of the Citadel Space are and at the same time, speaking with the only connection that they have to the humans and telling the Batarian ambassador to inform them the next time they meet a newly discovered space flight era species. Though the Citadel Species consider the video as hilarious, the Humans find the video assuring that whoever attacked them, they are not going to be attacked again due to the Asari Councilor being against such actions.

But that did not mean that they will simply drop their weapons and relax.

Somewhere within the dark corners of the Citadel Space however, one entity raged as it saw its plan fail to spark the anger of the Ones That Came Before to the ones that fell to their trap. Though they managed to destroy them a billion years ago, it was because their creators have severely weakened them in a petty war for domination. They tried to assimilate them along with their technologies, only to fail due to how prepared they were to thieves that dare to lay a finger on their technologies and their counters to their usual methods.

These so-called humans threw a wrench to their plans and pose as a threat to them.

"The Citadel Council wishes to give the Humans and the Systems Alliance its belated welcome to the galactic community." the Asari Councilor greeted the humans that are dressed in business suits and white military uniforms with multiple medals attached to show their ranks.

The humans stood on the other side of the Councilors, looking around the chambers where the meeting is being held. They saw a number of species that they haven't seen in their time in space that do not resemble too close to be mistaken as humans. Remembering how many autopsied corpses from the Gradosian Wars, the Balmarian-Zuvorg-Earth War, the Shura War, and the Gradosian-Balmarian Pacification Wars all of the results say that the aliens that invaded Earth and some of its fourteen core worlds have similar, if not similar then exact, body structure as the humans.

Though all of the said aliens are almost identical to the humans, instead of having a peaceful contact with them, the human aliens went to war with them. The Gradosians saw humans as a threat to their empire and invaded them during the early stages of their colonization under the banners of humanity needing to be reined under the Gradosian Empire's watchful eyes. The Balmarians, who makes the defunct Batarian Hegemony slavers look tame in comparison, intended to use humanity as a trained attack dogs after psionically enslaving them. The Zuvorg Alliance war was out of a great misunderstanding that was caused by an overzealous child genius/commander and his superior that saw humans as people who are too dangerous to live and deserved nothing more but to be exterminated. The Shura however, are nothing but battle-thirsty warriors who literally lives for war and battling.

All of the human aliens that waged war to humanity however, lost to the very species that they waged war with. Only two human alien races received the bad end of the stick, mainly the Balmarians who are dissolved and broken down as an empire and the Gradosians who are still recovering after their war with the humans up to now. The Zuvorg ended the war that was born out of a misunderstanding with diplomacy after the instigators of the said war were not in a position to disrupt the end of the conflict. The Shura left on their own when the newest leader, who did not wish to fight anymore, have decided to renew the culture of his people and find a way to remove the curse of their inability to sustain their lives outside of the battlefield.

Four human alien races waged war to the humans. And all four of them are defeated by the humans with weapons and technologies that are still experimental and at its infancy with two pacified and defanged later on after the humans have recovered and mustered enough strength and mastered what they have developed and information from the Zuvorg Alliance that revealed the preparations of the Balmarian Empire and the Gradosian Empire to once more attempt their conquest to the humans.

It was ironic that the ones who contacted and desired peace with the humans are supposed to be the very things that they could have shot and waged war with when they have met an alien that is not human-like. They are secretly glad that they wouldn't have to fight in a war with another species, but that did not mean that they will lay down their arms like so.

One of the human, a male with a short brown hair that is streaked with gray and brown mustache stepped forward. He wears a dark blue business suit with a white polo and red necktie underneath and has a golden badge that is decorated with a shield with three circles and multiple stars above a large half world within the shield that is pinned on the right side of his suit. The man looked calm as he began to speak.

"The Systems Alliance accepts your greetings, Councilors Adava, Pharesi, and Decius." the diplomat said in a polite tone. He looked at the area where the Councilors are.

The Batarian Ambassador Tilak said that the one at the center who looked like a human (something that the military got wary of) except for their blue skins, lacking any male gender, and having crests instead of hair is the Asari Councilor Adava, who is wearing an ornate red dress with white sleeves that extends up to the mid upper arms. Adava couldn't believe that they have found a race that looks nearly parallel to an Asari in terms of appearance if it weren't for their lack of crests and assorted skin complexion.

On her right is a hooded amphibian looking being that represents the Salarians and currently looking at them with great suspicion due to the fact that they have not deemed it important to contact any of them until they were attacked by the Turians, Councilor Pharesi, whose robes are somewhat similar to the black religious robes with yellow and crimson trims that the human diplomat has seen in many of the classic fantasy movies. He couldn't believe that the Batarians managed to keep them in the dark while the humans continue to operate under the table with them.

On her left is a being that looked quite similar to predatory birds except for the fact that they have no feathers and have metallic carapaces and mandibles for mouth, the Turian Councilor Decius, who wears a somewhat ceremonial version of the hard suit that the human ambassadors saw in many of the prisoners. Councilor Decius, who was once livid with what the humans have done with the patrol fleet, have calmed down after the humans have given evidences that they did not activate any Mass Relays and that it was their first time seeing one. Still, he still looks at humans with great suspicion due to how they remained out of contact from the greater community for so long.

"We of the Citadel Space are quite shocked and confused on why you did not contact any of us despite being given with the appropriate technologies and coordinates by the Batarian Confederation." Councilor Adava gave Ambassador Tilak a dirty look before looking at the human diplomat, "We would like to know why your people remained in the dark until you were attacked by General Octavius Oraka and his patrol fleet after the relay opened for unknown reasons, Diplomat Midcrid."

"The Systems Alliance, our representing arm to the Galactic Community, and the humans are not yet prepared for any contact with the Citadel Community." Midcrid answered the question calmly, "We were planning to contact you in the year 2057 of the Citadel Era via Batarians after Shanxi, the one of the few planets that we have that is near the Mass Relay that your people use, is secured and colonized. But then the Relay activated for some unknown reason and our stealth corvette's cloaking system has malfunctioned after passing through it and was turned into dust after warning us of the incoming patrol fleet."

"On behalf of the Turian Hierarchy, I apologize for the rash actions of the 125th Patrol Fleet and General Octavius Oraka, Diplomat Midcrid." Councilor Decius apologized, the humans in the military suits are rather doubtful of his apologies and were about to speak until one of them, a bald headed Caucasian with the Systems Alliance insignia attached on his right sleeve and a white star cutting across the black shield, gave them a hard look in order to stop them.

"It is accepted, Councilor Decius." the chosen speaker of the humanity said to them with a smile, "Before we begin, we would like to know why the Mass Relay that is positioned near Shanxi was activated all of the sudden." though his voice is rather calm, everyone inside the room knows the seriousness of the topic that was brought forth.

The three Councilors did not know what they should answer to the humans. The relay's sudden activation despite the fact that no ships came into contact with it after checking the ship logs that the humans provided to them and the ones provided on both Mass Relays was quite the surprising news to the Citadel's majority. They did not know how it happened and many speculations are being made by their experts on how it activated on its own. The Salarian Councilor Pharesi gave the answer to Diplomat Midcrid, an answer that many humans who are present are somewhat expecting.

"We do not know how it happened, Diplomat Midcrid." the Salarian said, causing the delegates of humanity to frown, "Investigations are currently being made in order to identify the cause behind the relay's sudden activation."

"I understand, Councilor Pharesi." Midcrid's frown was noted by his fellow delegates along with the slight change of tone to somber, "The Systems Alliance will have to make do with the explanation that you have given me about the Mass Relay's sudden activation, I suppose."

"Now then, shall we begin with the talks for the cessations of hostilities between the Systems Alliance and the Turian Hierarchy and a late ceremonial welcome that the Citadel Council should have given to the humans had the Batarian Confederation shared their discovery of them?" the Asari Councilor clasped her hands together with her hopes that the human's view towards the Citadel Space would improve after the negotiations. The last part of what she said illicited the Batarian ambasaddors and diplomats' amusement.

"Yes, it would be a boon to both sides if we begin the talks, councilors." the human diplomat's frown turned into a small smile.

The talks for ceasefire went well for both sides. The Humans agreed upon ending all possible forms of hostilities with the Turians and return the prisoners, the captured ships, and the Hierarchy's soldiers' cadavers that the humans have in their morgue in exchange of the recon vessel that was shot upon by the 125th Patrol Fleet and the bodies of the humans that were found inside the ship.

The Turians agreed upon the conditions without any hesitation despite the possibilities of acquiring new technological advancement from the slagged ship. They are not that stupid to alienate a newly discovered space flight species that was also one of the main reasons why the Batarian Hegemony stopped being a problem. Besides, they have all the time in the galaxy to study and develop the same technologies that the humans have.

After the negotiations for ceasefire are done, the Councilors and the Citadel diplomats welcomed the humans into the greater galactic community. They asked questions on human history, how they developed without the valued Element Zero, and if ever they were interested in joining the Citadel.

The first answer given on human history was somehow confusing and sad. Their transition from landlocked to space flight capable was bloody at best, especially in their early stages. The fact that they survived four genocidal, slavemaking, bloodthirsty alien races that are toting technologies that also do not rely on eezo is nothing short of amazing. They were also curious on why they fought them all despite their same resemblances with the humans, why fight instead of attempting diplomacy.

The military details that joined the diplomatic team answered by showing them various clips on humanity's attempt to stop the war with diplomacy before it could even begin and during the war with most of them ending in failure. They even showed one clip where the humans were nearly sold to the Balmarians as slaves by a group of diplomats who are later considered as traitors until Dr. Shuu Shirukawa, a scientist who developed the first Black Hole Reactor and the Granzon, destroyed the diplomatic meeting and singlehandedly took out both the human and the Balmarian security details while showing the world of the betrayal that the Earth Federation, the governing body of humanity back then, have done in order to save their own lives.

No humans would ever say the name of their old government without showing absolute disgust on what they have nearly done.

The second question not that simple to answer. Humans have developed at least three types of energy sources: Tronium, Black Hole, and the experimental Antimatter. Tronium remains as the most widely used energy source due to how abundant it was in human space. Black Hole Energy however, requires Artificial Intelligence in order to work properly due to how it needs constant surveillance. The entire chamber, except the Humans and the Batarians, looked wary when the humans said that they were using Artificial Intelligence and told the humans of the dangers of using it. The Humans told them that the AI that they use wouldn't harm anyone as long as they do not harm the AI, something that made the Asari Councilor pale and recalled one significant event in the Quarian Secession where a Quarian defended their AIs and stopped being a part of the Citadel when they were told to destroy them. Adava allowed the Humans to use the AIs on a condition that they keep them in human space despite the protests of some of the diplomats, mainly the Hanar and the Asari. The Antimatter however, is still at its infancy and not yet ready for large scale applications of any kind.

As for the questions of joining the Citadel Space however, the Humans showed the territories that they have explored and colonized; something that the Turians frowned upon due to how their military budget will be strained. The Systems Alliance own nineteen garden worlds and explored at least 70 solar systems, most of them are outside the Relay Network. Though the humans found a number of garden worlds that would make every Citadel race sell an arm and a leg to acquire one, they did not colonize them due to overstretching their military patrols. They also showed the human alien territorial borders and mining worlds that are currently being patrolled by humans. Revisions on the Treaty of Farixen were made in order to accommodate the patrol fleets that the humans use, something that the Turians do not mind due to how terrible the military and space naval doctrines that the Asari and the Salarians have and required them to defend their territories as well as theirs.

After the revisions on the Treaty of Farixen, the Systems Alliance is now a part of the Citadel Community, which the former regretted a little after being flooded with multiple trade requests and joint scientific researches and colonization projects from Citadel races after a few months but enjoyed some peace in dealing with aliens for once.

In an unknown area, a group of humans conferred with each other in a dimly lit room. All of them agreed upon the Citadel not being a threat so long as the boat was not rocked and the Systems Alliance would not attempt to run them to the ground just because some xenophobic and radical politician or general wanted humanity to be on top by force. There are other ways to be the dominant species without using too much muscle anyway.

After all, that was how they won against four highly advanced human alien species who tried to use force in order to subjugate and exterminate the humans and thought that humans would use theirs against them and fail and gained an alliance with a former slaver race that was converted to their line of thinking.

Balmarians and Gradosians learned the hard way and paying for the price of their idiocy, Zuvorg is starting to have normal diplomatic relations with the humans, and the Shura's warlike culture was changed for the betterment of their people thanks to that. The Citadel Community now is the ultimate test for all humans. They are now a part of a greater alien community that consists of beings of different shapes and sizes. No longer are they limited to the Zuvorg Alliance and the Batarian Confederation for trade and diplomatic ties for now, they are a part of a greater community. They now have other alien races to trade and grow with.

They also knew that the internal and external threats increased in numbers after the Systems Alliance's induction to the greater community.

They will not let them upset humanity's current position.

Doctor Bian Zoldark once said that humanity must be prepared for the threats that lurk within its heart and outside their homes. Doctor Shuu Shirukawa proved how a group of humans can be as dangerous to the safety and freedom of humanity as the threats outside the Sol System. Albatro Null, known in his human name as Eiji Asuka, has shown that not all aliens are ready to destroy humanity and would defend them willingly even if the odds are against them. Folka Albark, the current leader of the Shura, made the humans see that even aliens change for the betterment of everyone around them. Mekibos, a Zuvorg General turned Councilor of the Zuvorg Alliance, have given humanity the Zuvorg's hand of friendship and their assistance to rebuild what humanity lost. The Branstein Family, the United Colonies' influential backbone, stood with humans of Earth even if they were no longer a part of it and were targeted by countless opportunistic and greedy politicians that died during the foiled sale of humanity in the Antartica. Countless numbers of heroes that fought with humanity, both human and alien in origin proved that space and the unknown should be feared by those who are unprepared and ignorant.

The thoughts of humanity's current position and ways of life being threatened by a warmongering alien, a misunderstanding that would equal the Zuvorg-Human War's cause or a group of opportunistic or xenophobic humans sickened them. They will never allow humanity to be nearly driven to death or be indiscriminately seen as a threat thanks to those certain factors anymore.

If the Systems Alliance is the Shield and the Sword of humanity's body, then the Divine Crusaders is the Cloak and the Dagger of humanity's shadow.

Okay, since no one has done a Mass Effect and Super Robot Wars crossover, I've decided to take action and make one myself. This crossover is incredibly AU from the very beginning due to the SRW's history, which involves a certain time controlling human alien race that created the humans a billion years ago being severely weakened by a certain apex race that were dumb enough to create and program the Reapers. Thanks to that, the ancient human aliens died off thanks to that certain ancient apex race's stupidity and the last of their kind's mother ship/cryopod filled colonization ship became the Earth's moon, which will wake up some time later in the story and find the surviving ancient apex race to settle their grudges with.

Now, since this is a Mass Effect and Super Robot Wars, you'd probably see some other mecha series that were used in SRW like Fullmetal Panic, Gundam series, Go Nagai's Super Robot animes like Mazinger and Grendizer, Big O, and others. Don't expect Gurren Lagann, Code Geass, and other mecha animes that involves heavy AU on Earth's history though since I'm meshing Mass Effect's timeline with the Original Generation's timeline. For now, imagine MITHRIL going about in space instead of the Earth's water, kicking ass like the allies of justice they are, guarding living black boxes, and instead of being crewed by humans, it also includes Citadel races that also believe that they can do more good outside the system.

Though it is painful for me to put Shuu Shirukawa out early due to him doing his part in the Balmarian and Zuvorg Wars earlier and later, the La Grias incident, I really couldn't find any reason to bring in the trolling doctor that throws around black holes like it was nobody's business into the crossover without resorting to lol!MAGIC or lol!SCIENCE. That goes the same for Sanger Zonvolt, Ratsel Feinschmeker, Masaki Ando, Lune Zoldark, the entire La Grias crew, the SRW crew, and many significant and somewhat manly SRW characters that were involved in Balmarian, Zuvorg, and Shura wars. That doesn't mean that I wouldn't bring in other Original Generations characters that were made and characters from other series in the mix.

Anyway, if you guys have anything to say, do write up a review.
