This is my first story, so I hope to get constructive criticism, advice and a bit of support wouldn't be bad either.

Disclaimer: All characters from the Megaman universe belong to Capcom and Keiji Inafune.

This story will show OC's as well as other characters from the Megaman series.Very important: In this story I will make both pairs of past main characters collide, having: Vent, Aile, Grey and Ashe, all in one story. Maybe I'll make a story explaining that some time after this one.

Chapter 1: "Biometal?!"

Some months have passed since Albert's attack, and the hunter base seems peaceful and happy. Thanks to the Biometal users Grey, Ashe and Aile, there weren't many problems in the surrounding areas, and Vent, although having lost biometal model Z, was still working hard as a commander in the base.

Everything seemed normal, until one day, the monitors where showing a massive amount of what seemed as dissident reploids going to a random location in the middle of the desert. Of course there couldn't be anything random with this, and the hunters noticed immediately.

"I want all three special squads heading to the area in question!" Vent ordered through a communicator.

"Yes, sir!" Was heard in unison through the device.

"Ashe, you lead them through the center, while Ashe and Grey will be covering you from the sides. We must cover the area as much as possible!" Vent said.

"Ok, I'll make sure teams α, β and γ don't suffer any losses" Ashe said.

"And we'll have your back!" Grey said. "So give it your all!" Ashe completed.

Some time after arriving*

"This is weird..." Ashe said with a suspicious voice. "We're destroying hundreds of them, but they just move on, almost without fighting back" She finished.

"Absolutely, this is not a fight... It's a massacre!" Ashe's Model Al [short for model Albert] answered to her thought.

"What could be so important that they don't care sacrificing so many?" Aile thought in her head.

And there they saw it. What was supposed to be just another part of the immense desert was in fact a base, but one that seemed very old, with a damaged structure, possibly by the years in solitude.

"Whatever there is in that base, we can't let them reach it!" Grey said with decision.

"We'll have to finish them all quick, I guess" Aile answered.

And thus, the two Megamen started to unleash a barrage of attacks upon the left reploids, which were annihilated by buster shots in seconds.

"I thought that would never end" Aile sighed.

Her Biometal separated from her for a moment though.

"I feel a strong source of energy coming from deeper into that building" Model X said. "It could be a Biometal!" He finished.

"ANOTHER BIOMETAL?!" Grey's Model Al cried in surprise.

"Even though we were all created around the same time, we were in a state of sleep after the process that turned us into Biometals, so there could be others that neither I or Z would know about" Model X stated.

"Anyway, we should hurry and get it before another horde of those reploids come to the place" Grey said with decision.

"I don't think you should worry about the reploids" a childish familiar voice said full of pride.

Grey, Aile and Ashe turned around to see who was there: Thetis, and not alone, since the other rogue Megamen were there too.

"Did you really think you were the first to find the biometal? We sent those pieces of garbage to look for it, but it seems they are not even good for that" Aeolus said scornfully.

"We knew something was wrong, but I'd have never thought that YOU were behind this!" Grey shouted.

(Atlas took a step forward) "Look who's all cocky here. Just because you've defeated us before doesn't make you so strong. As a matter of fact, we've learned some tricks that make us stronger!" She finished.

(Aile was still in shock though) "But how?! Me and Vent were there when Model Z decided to stay behind and stop you all from using your biometals... You couldn't have survived inside Ouroboros after it crumbled and collapsed into the sea!" She said confused.

"Let's just say that someone was interested in us and decided to save us for some reason" Aeolus said.

"But who would and COULD have done something like that? Even if someone was watching after you, it would be almost impossible to do something about you in that situation!" Ashe asked.

"Being honest, we don't know how the Master was able to do it either! But the only thing important is that we're here to play once again! I've been looking forward for a rematch!" Thetis dared.

"We're not here to play fish-head! We're here to burn these creeps to ashes!" Atlas said to Thetis.

"You behave quite like a macho, even though you are a lady!" Thetis teased in reply to Atlas.

"I have an idea for today's meal. Do you see yourself turning into a plate of fish and chips, Thetis?" Atlas dared.

"I'll put off those flames of yours!" Thetis said.

"Unless you are burnt to a crisp in the next seconds!" Atlas answered angrily.

"TEAM WORK STRATEGY. STATUS. ENDENGARED. PREPARING TO FIGHT AS AN INDIVIDUAL." Siarnaq said with his robotic voice.

"Everyone shut up!" Aeolus ordered. "The Master ordered that we had to fight as a team, and I firmly believe that the only way to win this fight is behaving as allies at least for this moment!" He finished.

"INDIVIDUAL FIGHTING STRATEGY. CANCELLED. COMMENCING COMBAT USING PREVIOUS STRATEGY." Siarnaq said.

"Bring it on!" said Ashe.

And a choir of "MEGAMERGE" was heard.

And the battle started. Aile had decided to fight one on one with Aeolus, while Ashe fought Siarnaq, and Grey took on Atlas and Thetis.

Aile was shooting charged shots with her buster, which were dodged by Aeolus when were fully charged and sliced by his blades when charged at half.

"Is that all? Not amusing..." Aeolus said while making a boredom pose.

"Of course not silly! I'm just playing with you" Aile answered.

Aeolus used his special attack (the one of the moving blades) "Then we better start to get serious" he finished.

"As you wish" Aile answered while charging her buster to the maximum.

Meanwhile*

Ashe was shooting at Siarnaq just a moment before he disappeared into the shadows. "And what about the teamwork stuff you said earlier? You're fighting alone, just like always" Ashe asked the model P user.

"TEAM STRATEGY. SEPARATE MEGAMEN FOR SMOOTHER ERASURE. STATUS. IN PROGRESS." Siarnaq answered.

"It's a pretty basic strategy you know? And I don't think it's working either" She told him with a grin.

"MASTER ORDERS. NO QUESTIONS ASKED." He said with a colder tone than usual [if it's possible] and he used his special attack, creating shadow clones that seemed more powerful, since they could now throw big ninja stars, instead of the small kunai.

And meanwhile*

"Are you sure about taking 2 of us by yourself?" Thetis asked Grey with a smile on his face.

"I wouldn't mind taking all 4 of you either" Grey answered him.

"You have become quite confident, as you're not the scaredy cat we met in the ice anymore... Actually, I kinda like your style, but orders are orders, and I'm still pissed about what happened at the desert!" Atlas told him.

"Come and get me, if you have what it takes!" Grey dared.

Thetis and Atlas charged. The blue Megaman tried to stab Grey with his lance, but was surprised when the "defective" evaded his attack and delivered him a fully charged shot.

"Agh!" He screamed with pain as he fell to the floor.

Atlas tried to push Grey with her buster from behind, but Grey jumped a moment earlier, and scoped a barrage of guided shots to her. She could avoid the first two, but the rest caught her, dealing a big amount of damage.

"Damn it!" She cursed.

"Hey Atlas!" Thetis caught her attention while standing up with difficulty. "What about that combined attack the Master made us practice?"

"I hate teaming up" she said at first, but she saw Grey preparing to deal another attack... "But you know... It doesn't seem like a bad idea".

"Then let's do it!" Thetis said.

The model L user started to create a polar wave with sharp pieces of ice pointing at Grey, and once he threw the attack, Grey was prepared to avoid it, but suddenly, Atlas blasted a spiral of fire that was covering the ice attack in a way that it wasn't melted.

The Megaman was cornered, so he decided to use his special attack, shooting a barrage of blasts towards the attack.

To his surprise, not only had it worked, but it left the other 2 Megamen beaten in the ground.

"I can't even move!" Thetis shouted full of rage and impotency.

"Curse you defect!" The woman insulted him.

But he couldn't care less. He turned his back (since they couldn't move anymore) and ran towards his friends, since they were still fighting.

He thought Ashe would be alright, so he went to aid Aile first. And thank God he did, because Aeolus was giving her quite a hard time.

He ran towards the fight and jumped just in time to catch Aile and save her from a slice of one of Aeolus's blades.

"I can't believe my eyes" Aeolus said with a faint smile in his face. "It seems that you defeated two of us... I didn't expect you to be THAT strong, but since you defeated Albert it is how it should be. You'll be much more entertaining than this girl, as she has weakened up a bit since the last time we met" He finished.

"I'll handle this guy, you go help Ashe" he said to Aile.

"I hate that things turned out this way, but I guess it's for the best" Aile said bitterly, then she went towards Ashe, who was still in a heated up fight with Siarnaq.

Grey started fighting Aeolus in the background.

"Need some help here?" She happily asked Ashe.

"I wouldn't mind if you gave me a hand actually, this guy is indeed stronger than before!" Ashe admitted.

"NEW NUMBER OF ENEMIES. 2. PREPARE FOR ADVANCED COMBAT PROCEDURE." Siarnaq responded to Aile joining the fight.

"This guy gives me the creeps!" Aile said as Siarnaq made his red eye shine.

Then Siarnaq's body started to shine as a shadow started engulfing his body.

"Okay...? Just what the hell is happening?!" Ashe said scared and confused.

Any ideas of what's happening? Remember that biometals are made from the guardians.

That's the only clue I'm giving. I'll start writing chapter 2
