NATASHA POV:

"Steve, we need additional manpower to deal with these stupid robots." I said to Captain America while fighting the robots Ultron had created.

"She's right. We need re-enforcements." Clint added.

"Quicksilver!" Steve said. "Can you run to the Xavier Institute to gather more manpower?" He asked.

"Sure. I'm on it." Pietro said and dashed as fast as he could.

"Retreat!" Tony ordered. "We cannot handle this bunch with our small team." He continued.

"Let us wait for the return of Pietro. Maybe he'll bring a bunch of re-enforcements." Steve replied.

"But we can't just stand here and beat ourselves up." Clint said.

"So what should we do now?" Vision asked.

"I think we should fall back. We need to gather all the power we can and plan for our next attack." Thor suggested.

Everyone rushed to the plane and Clint pilot the craft. Wanda created fields that would not allow the attacks from Ultron's bots to crush the aircraft. Steve contacted Pietro to lead the re-enforcements to the Avengers building, while I sang the lullaby to calm down Bruce. We landed safely at our HQ and started to strategize for the next attack.

PIETRO POV:

I've reached my destination and knocked at the huge doors of Xavier Institute. But before my fist touched the doors, bright light shined just right in front of me and after the light faded, two boys stood in front of me.

"How may I help you?" The boy with crimson hair asked me.

"Who are you?" The boy with azure hair asked.

"I am-" I said but the crimson haired boy cut my sentence.

"You are Pietro Maximoff from the Avengers, right?" He asked me. "I'm Daisuke Pryde and he is my twin brother Dale." He continued.

"You wanted to talk with Professor X, am I right?" Dale asked me and I nodded.

They opened the doors and we entered the vicinity. I let my eyes roam around and noticed that they wore uniforms with "X" marks. I noticed a familiar face but I cannot recall when and where did I met him so I just disregarded the guy and focused on the mission.

"Professor X, somebody wanted to talk to you." Daisuke said upon entering the office of Professor X.

"Glad to meet you again Pietro. How is your sister?" Professor X asked.

"Wait? What? You know us? But how?" I asked.

"You are my bestfrie-" He didn't have a chance to finish his sentence because a man with white hair entered the room.

"Just shut up will you?" The man said.

"I'm Erik Lehnsherr and he's my best friend Charles Xavier." The white hair dude said.

"But how did he know about me and Wanda?" I asked him.

"Just spare that explanation later. The Avengers need help in battling those Ultron bots right?" Daisuke asked.

"How did you know about that?" I asked him.

"One of his mutations is to read minds." Dale answered.

"Ok then, I'll go with them. I'll bring with me Dale and Daisuke." Erik said.

"Call him Magneto." Professor X said.

"You should address Dale as Azure and Daisuke as Crimson." Erik said.

"So shall we go now, Quicksilver?" Daisuke asked.

I nodded and he opened up a portal and everybody went in so I followed them.

STEVE POV:

"Let us plan for our next attack when the re-enforcements arrive." Thor suggested and a portal opened just right in front of us.

"Hello guys, I'm back." Pietro said. "I'm with Magneto, Crimson, and Azure." He added.

"They are the strongest among the mutants. How will they survive the sentinels without them?" Wanda said.

"They can handle it. Besides, Charles and Wolverine are with them." The man that Pietro addressed as Magneto answered.

"I'm Captain America that is Thor, this is Black Widow that one over there is Iron Man the other one's Hawkeye here is Hulk and the twins-" I said but Magneto cut me.

"Yeah, the twins. Pietro and Wanda Maximoff." Magneto said.

Everyone was shocked that Magneto knew the twins but the two mutants seemed to know what was happening.

"Let us continue to our planning. Let us spare the explanation later." Crimson said.

"If we need some more re-enforcements, we could contact the 4." Azure said.

"Are you sure that both of you are ready to work with them?" Magneto asked.

"If we need to, then we can work together." Crimson replied.

"Could you contact them?" Hulk said.

"Yeah, I'll do the honors to bring them your message." Crimson said.

"Can you do it yourself, or do you need Pietro or Hawkeye to assist you?" Magneto asked.

"They would not be pleased if I'm going there with a guy." Crimson replied. "But I'll go with Clint." He added.

Once again, everyone was shocked that Crimson knew the real name of Hawkeye.

"By the way, one of our mutations is that we could read minds, so don't be so shocked if Crimson and I addresses you in your real names. Ok?" Azure said.

After that, Crimson summoned a portal and they vanished. While they were gone we continued in getting to know each other.

"I am Erik Lehnsherr. My mutation is that I could attract metal just like a magnet so they called me Magneto." Erik said.

"I'm Dale Pryde and Daisuke is my twin brother. Our mutation is that we could copy the mutations of other mutants." Dale explained.

Everybody then introduced their own identity to the X-Men. Then we planned for the attack and waited for Clint and Daisuke together with the Fantastic 4 to arrive.

DALE POV:

"Is there something wrong between the both of you and the Fantastic 4?" Steve asked.

"It is a long story captain. Let us first deal with the current situation and talk about these kinds of matter later." Dale said.

"But how did Erik know us? And why does Professor X asked how Wanda and I are?" Pietro asked me. "And the reactions you gave us when Erik told our names." He continued.

"Just as Dale said, let us spare the story for the latter part. Let us dwell now on how we would exterminate that Ultron thing." Erik said.

We all agreed to that and we started to move to our postings. I opened a portal opening to the north side of Ultron's base where Natasha and Bruce were assigned. Then I opened another one to the west side of the base where Steve and Erik were assigned. I opened one on the east where Wanda and Pietro were stationed. And finally I teleported to the south part of the base where I was supposed to infiltrate. We left a message at the Avengers base for the designation of the Fantastic 4 and Clint and Daisuke.

We all waited for the chance to attack and suppress them in the middle of the base but we were caught in Ultron's trap. Ultron was able to control even the sentinels that were attacking the mutants so the robot army of Ultron gained numbers. We were surrounded by the Ultron bots together with the sentinels. All I could do is to put a force field around us to shield their attacks. Where the hell are Clint and Daisuke? Are they gonna be here to save us? Did they got the support of the Fantastic 4 or did the Fantastic 4 capture them?
