Hey everyone, this is something I'm uploading for anyone following this account, since I haven't posted in a long time. I had an X-men/Teen Titans story in the works that was part of my Spider-man/Teen Titans story, but nobody seemed all that interested in it, so I dropped it to work on this and other ideas. Also,Cyclops and Jean's relationship is going to be a big part of this story, and it also would've been in the X-men/Titans one too, so I felt that would've just been redundant. So, here it is, the first bit of the Marvel/My Hero Academia crossover, let me know what you think.

Xavier School for the Gifted: Danger Room, seven years ago

"Excellent Scott," Professor Xavier's voice announced from the room's control booth, "your control of your optic blasts has improved greatly." In between blasts, the young man replied, "Thank you, sir." Scott Summers was running an individual training test after his teammates, the other X-men, had already run theirs. The course was simply to test his accuracy and reflexes with his optic blasts, and he had done well so far, until the final round, where at least fifteen holographic enemies formed at once, coming from all sides. "Professor," he exclaimed, "I don't think I can take all of them!"

"Try, Scott.", Xavier said, reassuringly.

"Yes sir.", Scott replied, still nervous. He attempted to blast each enemy individually, but had no time, and a few grabbed him from behind. He tried throwing them off, but one in front punched him in the gut, knocking the wind out of him, and as he tried reaching for the button on his visor, another pulled his hand away, and, beginning to panic, he shouted, "Professor!"

"Danger Room, cease program!", Xavier's voice boomed. The enemies disappeared, and Scott fell to the floor in a heap. Within a few seconds he managed to stand back up, and his teacher called out, "Meet me outside the changing room." The young mutant coughed out a response, "Right away, sir.", and made his way to the changing room, switching from his yellow and blue uniform to his civilian clothing, and switching out his visor for his casual glasses. He then walked through the automatic door to find the Professor waiting for him, and the two made their way to the elevator leading to the main school. As they moved through the hallways, Scott spoke up, "I'm sorry, professor, I should've handled that better."

"It's alright Scott, you along with the other X-men are still learning, and I understand how you feel about the power of your eyes. In time, you will be able to push past those fears and truly master your power."

"I'll keep trying sir."

"I know you will, I also believe we may need to add an alternate way for you to activate the visor, so you won't always have to reach the buttons on it. In the meantime, there's someone I'd like you to meet, a new student is arriving today, in fact, I sense her thought patterns at the front door now." They entered the front room as the door opened, and Scott's mouth dropped slightly as a beautiful red-haired girl about his age walked in. "Hello Jean.", Xavier said to her. "Scott Summers, this is Jean Grey, your new classmate. Jean, this is Scott." She gave a kind smile and said, "Hello professor, nice to meet you, Scott." The young man felt his heart begin to beat faster, and he replied, "H-hi, uh, Jean." The professor then added, "My apologies, Jean, but I can't give you a tour of the school at the moment, I have some work to look over, but I'm sure Scott can show you around."

Almost in a trance, the young man replied, "W-what? Oh, uh, of course I can!"

"Excellent, I'll leave you to it then. Jean already knows about the X-men, so feel free to show her any part of the mansion.", he turned to Jean and added, "You can leave your things at the door, I'll have one of the other students take them to your room." With that, he left for his office.

"Well, uh, right this way.", Scott began nervously, and the two started to walk down the hallway to the right. Jean then commented, "So, what's up with the shades indoors?"

"Huh? Oh, you mean these!", he touched the sides of his glasses and continued, "Well, they have to do with my mutation, you see, I shoot these energy beams out of my eyes, but I can't turn them off, and this red stuff, ruby quartz, it's the only thing that can stop them." Her expression saddened a little and she replied, "Oh, I'm sorry, I didn't…"

"Hey, don't worry, it is what it is. So, what's your power?" Her face brightened again, and she answered, "Oh, well I can move things with my mind, see?" She moved her hand up and concentrated on a vase sitting on a table, which began to hover for a few moments before she put it back down. "I can't hold it for very long, but the professor says he can teach me to do a lot more."

"Yep, after a while here you'll be moving way more than little stuff like that. Speaking of which, wanna start the tour with the cool stuff?"

With a smile Jean replied, "Absolutely." Scott walked over to a blank space on the wall and pressed a hidden button which caused the panel to slide to the side, revealing the hidden elevator which they took down to the lower levels. "Woah…" Jean said in wonder as they entered the steel halls of the underground complex. Scott smiled and said, "This isn't even the best part." He guided Jean into the control booth for the Danger Room and explained, "This is our training room, it can create any kind of scenario we program it to."

"No way." The red haired girl replied.

"Seriously. Check this out: Danger Room, continue program." With that, the enemies the young man had been fighting earlier reappeared, and he grinned at Jean's look of amazement. She asked, "They're holograms?"

"Yep." Scott rubbed his gut and added, "Solid ones though, it's like fighting the real thing, but there are failsafes in the system that keep them from… uh… killing us." Jean's look of surprise turned to shock, and she asked, "Kill? What are you guys training for exactly?"

"The professor told you about the X-men, right?"

"Well, yeah, he said it was something I could join if I wanted to, but the main reason I'm here is to just learn better control of my power."

"Well, the way the professor put it, is that there are some mutants in this world that misuse their power, and there's gonna need to be people who can protect… well, non-mutant people from them. That's what the X-men are for."

"So you're his soldiers?"

"The way he put it is he wants us to be superheroes, like the Fantastic Four, we've even got costumes like theirs."

"Costumes?"

"Yeah, c'mon, I'll show you." They entered the changing room and he showed her the display cases for the yellow and blue uniforms, and she asked, "So do you have names? Like the Human Torch or the Thing?"

"Yeah, the others have picked theirs, Beast, Angel, and Iceman."

"What about you?"

Scott rubbed the back of his neck awkwardly and answered, "I uh, I haven't come up with one yet. Well, the others have for me, but I don't really like it."

"What is it?"

"…Cyclops. 'Cause, y'see the visor on that suit?", he pointed to the one in the middle, "That's mine. They call me Cyclops because of the single lens, it slides up and down so I can control when the blasts fire."

"Why don't you like it?"

"Well, I mean, I think it's kinda demeaning. The word cyclops makes me think of a big, dumb, ugly monster, y'know."

The red haired girl giggled and replied, "You really need to loosen up, you're so uptight."

"What?"

"Does the guy named Beast think his name is demeaning?"

"Well… uh… no, actually."

"Well, don't feel bad about yours. I think Cyclops is a cool name."

Scott felt his chest heat up a bit and he replied, "You… do?"

"Mhm."

The young man smiled and replied, "Well, maybe I could reconsider it." The girl giggled again and said, "We'll work on you loosening up. So, how about the rest of that tour?"

Much changed over the years since that first meeting, more heroes began to emerge, some forming the team known as the Avengers, while others worked alone. The X-men themselves changed, new members joined, and some came and went. One thing remained consistent though, Scott Summers and Jean Grey's love for each other, a love that helped Jean survive losing herself to the control of an entity known as the Phoenix Force.

Present Day

Cyclops entered the operating booth of the Danger Room and looked through the glass to see Wolverine, Storm, and Nightcrawler standing at the ready. He spoke into the control panel's microphone, "Sorry I'm late people." Wolverine responded, "The boy scout's actually late, never thought I'd see the day." Storm added, "It is quite odd of you, Scott, usually you're the first here." Scott answered, "I know, but we were running another check to make sure none of the Phoenix survived within Jean. I know it's been over a year and we've run the tests hundreds of times, but we can't be too careful, especially with the baby on the way. Anyway, without further ado let's get this session… started…" His sentence trailed off as he suddenly noticed a black mist-like substance in the shape of a circle appear behind the X-men, and he said, "Storm, are you doing that?"

"Doing what?"

"Behind you!"

The X-men turned to look at the black circle, and Storm responded in alarm, "No, this is not me!" Nightcrawler added, "Is the Danger Room malfunctioning?" Cyclops answered, "I'm not seeing anything to indicate that on the control panel. I don't know what that thing is!" Wolverine then popped his claws and spoke in a serious tone, "I don't like the feelin' I'm gettin' off that thing…"

Then a figure appeared out of the circle and it disappeared behind him, it was a young man around the age of fifteen with spikey blond hair. His outfit was not out of place among the X-men, he wore a sleeveless black shirt that had an orange X across the chest, baggy black pants, black boots, and large grenade shaped gauntlets on either arm. He also had some sort of a mask that covered his eyes and trailed off in the shape of explosions to either side of his head. There was complete, deafening silence as the young man stared at the other occupants of the room, his expression showing as much confusion as theirs, until that expression became anger as he growled, "What the hell is this?" Wolverine returned, "Exactly what we're wonderin', bub, who are you?" The new arrival gritted his teeth and darted his eyes around the room, then he suddenly aimed his hands at the floor in front of the X-men, and small explosions fired from his palms, knocking them off balance and launching him into the air. He then placed both hands behind himself and fired off more explosions from them, propelling himself across the room and to the exit door, which he blasted open, then took off through the opening.

He didn't make it far however, as the exit lead directly into the control booth where Cyclops was at the ready. "Hold it.", the team leader said, readying himself to squeeze the button in the thumb of his glove that would open the lens of his visor. The boy didn't respond and instead fired a blast at Cyclops, who, in a blinding motion, rolled out of the way, steadied himself, and released an optic blast directly into his opponent's chest, knocking him back into the wall and onto the floor. The boy stood back up with a look in his eyes that Scott noticed was similar to Wolverine's when in a berserker rage, but before either of them could do anything, a strong gust of wind lifted the intruder off his feet, and in a puff of smoke Nightcrawler appeared before him to deliver a knockout punch. Cyclops looked down the hall to see Storm gesturing for the winds to die down, and Wolverine, who was making his way up the hall, said, "That kid don't smell right."

"Any ideas what this is all about?", Scott asked him.

"Not a damn clue, I just know somethin' ain't right about him."

"No kidding. Come on, let's get him in a containment cell before he comes to."
