Hey everyone, GunPro X here. Seriously guys, why have only a few people ever done this? As a fan from series of Megaman and Mass Effect, I'm kinda disappointed to find only 2 guys wrote stories about this kind of crossover. Well, I think they have stopped since it has been years since they have uploaded any new chapter.

Well, this idea was an inspiration from Shadow Guyver' story, though in a different approach. Here, I won't just insert a few Reploids like X, Zero and Axl, but I'll introduce them as a race called Humanoids. Yep, it follows after ZX Advent storyline and also I'll be using their Reploid style here.

I guess this introduction is enough to clear this up. Happy Reading!

Prologue

Journal of Commander Aile, leader of the Guardians:

June 21th, 2532 - Today is the day where I can finally sit on my chair and sigh happily. Our enemy, the Ultimate Biometal Ouroboros which was formed from several Model W parts, was destroyed with the help of the Model A Chosen One called Grey. Master Albert, who was responsible for awakening all those parts, has also perished in the explosion. However, the victory came with a great cost to us, the Guardians. Model Z sacrificed himself to hold back the other Megamen while I tried to rescue Grey from the exploding Ouroboros. I don't know what happened to them, heck I don't even care what happens to those four mongrels, but I hope Model Z comes back safe and sound.

June 22th, 2532 - We established a perimeter around the explosion site to locate any Model W par that survived. With the help of Grey and his Hunters, we destroyed everything that resembled to that wretched piece of Biometal. Around late afternoon, Model Z appeared before me with H, P, L and F, stating that "If he went offline with that explosion, he would be shaming his ancestor." Me and Model X were so happy that we threw a party to welcome him back at our HQ, the Grand Nuage. As for the guys who wore the other Models, I can believe they didn't survive the explosion.

February 5th, 2534 - In these 20 months, we noticed a decrease in the Maverick numbers at the Outer Regions. We also found out their attacks were poorly coordinated compared to two years ago. Fleuve believes that, with Model W terminated, the Mavericks lost their main source of their outbreaks and are acting on pure "individuality". I for one refuse to accept that they are individuals after they have done to my parents a few years ago at Cinque Ville. Suffice to say at least, those news gives us a tactical advantage and a moral boost against those freaks.

March 12th, 2534 - Tonight is an important day as me and Grey, now leader of the Hunters, join our organizations as one. We both knew that Guardians and the Hunters had the most experience in the field against the Mavericks, so we had a meeting where he suggested that our forces joined together into one to not just eliminate the Maverick threat, but also protect from whatever enemy wanted to cause harm on Humanoids. He also suggested that the Hunter Base should be the HQ for the organization, which I agreed since the Grand Nuaque couldn't afford to house both Guardians and Hunters soldiers. All in all, I'm proud to write this as the first to announce that the Maverick Hunters will be reborn this night, the same as it was before. I hope Lord X and Lord Zero are watching us in this day from Cyberspace.

January 15th, 2535 - Trade routes between nations from Innerpeace started to reform as the Maverick Hunters kept the push to wipe out the Mavericks from existence. As a result, our civilization took its first footsteps outside Innerpeace.

May 21th, 2540 - From what I have been seeing so far, the Humanoids have really grown in such short time. Our maps show that we had reclaimed almost 60% of our original territory compared to what we had back in 21st century. It's not surprising that the Legion had announced yesterday to the public that Innerpeace would begin the Earth Repopulation attempt next month. In the meantime, the Sages entrusted us to keep the civilians protected against Maverick straglers.

January 2nd, 2541 - Grey finally confessed to me today. I always made sure, since a year ago, to make my moves obvious enough to even the dumbest of people notice I wanted something more than our friendship. But, he is way too dense for it. Three days ago, in a talk with Model A, I discovered that Grey actually had feelings for me since he liked to talk much about me in his opinion. He said he would make Grey "man up" to make him see reason. So, I guess I owe him one.

March 14th, 2541 - Guess who came back to our organization? Yep, Prairie! At first, I couldn't recognize her since she had been modified into a more adult body, but when she talked to me I knew something felt familiar on her. After a bit of chat, I offered her position back as the commander of the Maverick Hunters, but she refused and said I was better suited than her in the situation. Modest girl, I tell ya. It's so damn good to have her back.

April 29th, 2555 - The Humanoids take a step to space exploration once again as the Legion sent a shuttle to the Moon in attempt to construct the first extraterrestrial base. They decided to name it as Nuaque Base in honor to our mobile battleship.

February 8th, 2561 - Mars Expedition is launched in an attempt to colonize it and further explore for new resources. They will set their first city on the planet at the Eos Chasma. I fear the Maverick Hunters will have to set their eyes to space soon if we want to continue protecting Earth...

July 4th, 2562- The Legion announced the construction of a massive orbital shipyard planet ring around Earth as the start of a space navy production for Sol System defense operations. A daring feat if it's ever concluded. They even suggested the first ship produced would be a dreadnought for our organization as a thanks for wiping out the Mavericks. If anything, I'm quite flattered.

August 21th, 2570 - I heard some Mars miners found something at the southern pole of the planet. They said they unearthed some kind of alien research facility, I think. Our scientists are already studying the data stored in there.

October 1st, 2570 - Our scientists figured the monolith the miners found. Apparently, it was an outpost for observing humanity by a species called Prothean. The last records show they were made approximately 50,000 years ago though. Not sure what to make of that. At least, the public has made up their minds and now, it seems we will get united.

January 10th, 2571 - The Legion has taken the last step to a world-wide unification. The Protheans are out there somewhere and our race can't play unprepared like we did with Maverick and Elf Wars. The nations of old Innerpeace banded together into the United Humanoid Systems which aims to ensure we, humans and Reploids, are never at risk like we were before. With SolForce (The Maverick Hunters was renamed after the completion of our flagship Hexagon of Arcadia in honor to the Guardians of Neo Arcadia, forgot to add this here) as the sword and shield of the UHS, I intend to do the same.

May 3rd, 2571 - Our scientists made a breakthrough from the Prothean artifacts we recovered from their base on Mars. At first, they were nonfunctional but when exposed to an electromagnetic field, their mass changes. They already isolated the material that triggers the change, they called it Element Zero. It seems it produces an amount of energy even higher than nuclear fusion!

,September 12th, 2574 - The Protheans may be more of a threat than I had thought. Explorers on the edge of the solar system noticed something strange about Pluto's moon. Turns out it's some kind of Prothean station, buried in ice after they left it behind. It's too damn massive. It almost scares the crap out of me. We can't fight a race like this when we're still packing our fleets. I pray to X and Zero that they stay away until we're ready for them.

December 9th, 2574 - Our scientists concluded that the Prothean station on the edge of our system is actually a transportation device. Somehow, it uses Element Zero to send objects at higher speed than normal FTL to another sector of space and it seems range isn't a bother to this technology.

May 1st, 2575 - If we ever enter in ground battle with the Protheans, we need every advantage we can get. That's why me, Grey and a handful of our most trusted scientists and engineers decided to start Project Albion. He'll represent the first of a new generation of warriors capable to adapt to multiple environments, including space battles, and shift his own armor into differents one with distinct combat styles that suit his needs in battle. We estimate that this Project should be completed in approximately four years.

June 30th, 2576 - The Humanoids now have a wide range of territory, thanks to those "mass relays" as we decided to call those Prothean stations. We have 37 colonies and three fleets consisting of 150 ships with still more to come from the Orbital Shipyard. As one of SolForce leaders, I'm proud with progress we have accomplished so far.

October 10th, 2580 - I have received a report from Grey that his research team found another relay at the edge of Shanxi' system. However, they were delayed as the artifact was buried in ice. He said the work should be completed tomorrow by early morning, but I can't shake this feeling that something is going to happen there. I hope everything goes okay with them.

Next chapter, I'll start writing codexs about this new race in ME Universe. Also, I think some pics shall help you see how exactly things are in this story. Things such as ships, main character and so on. I'll post them on chapter 2.

Also, I'd like to thank shynerdylady in accepting a partnership as the beta-reader for this story. She's kinda of new in Megaman Universe, but has an excellent view of Mass Effect which will be decisive in making this story a success. I'm very close of posting Chapter 1, just waiting Lady to give me green light to proceed. And thanks to the people that have already read it and followed/faved/reviewed, I'll try not to disappoint.

I'm also up to suggestions from you guys. Any thoughts that you have mind that you feel it's good, send a PM and we'll discuss about it. Don't hesitate to share if you have an idea!
