The ocean was its usual serene self which was how Izuku enjoyed it, like he was right now. It was currently the summer of his second year at UA and boy things had been amped up by the aftermath of the Flooding War as the heroes called it due to Japan becoming flooded, so here he was enjoying the calm blue waters when he saw something drifting by him.
"That's new" he said as he swam over to the object, which was much larger then he originally thought. He was flabbergasted as someone had made a metallic moving island. "Okay when did they do this?" he asked before he had to move out of the way of large metal island before he saw something being dumped into the ocean, frowning he examined it revealing it to be some kind of robot. "And now they're dumping in the water, can't have that now" he said before speeding over to the island, he had to avoid what appeared to be an engine of some kind, so he grabbed onto a nearby fin and looked around to see if he can find an access point, upon finding one he swam over to it and entered it.
Once he was out of the water he looked around and noticed it looked like a standard city or town. Suddenly a human looking robot landed in front of him. Izuku smiled before punching straight through it and flung it into another one
"Alert new meta detected" another said as several more crowded around Izuku who just cracked his knuckles and jumped at one of them crushing it before turning to another one and kicking it to pieces
"Hey buddy, duck" a voice said making duck before a robot crashed into several more "STRIKE!" she cheered
"Who is she?' Izuku said before destroying the last one, he turned to the girl before catching her fist "What did I do?"
"I don't know who you are, or why your here but you aren't getting away" she said before Izuku threw he, once he got a good look at her, he noticed she was wearing what looked like a white midriff top with the Superman shield, blue skirt a red cape that went down to her hip, knee length high heeled boots and a pair of white gloves
"And you are?" he asked
"I'm Supergirl" she said flying back before heading towards Izuku, who just held his hands out as they connected with Supergirl's shoulders pushing them back and bit; making her hit the ground "right asshole" she said floating in the air before shooting at Izuku, who rolled under her, grabbed her cape pulling her to the ground
"Come on then" Izuku said smirking as he leapt at Supergirl, surprised by the attack rolled out of the way and got back on her feet and charged at the quarter Atlantean ready to punch him as he was ready to punch her
"WHOA!" a voice said catching their fists "First take it easy, secondly what is going on here?" the voice asked making the two look up and seeing Wonder Girl standing there holding there fist
"Cassie, this guy just showed up" Kara said stepping back
"Who, Izuku?" Cassie asked
"Hey Cass" Izuku said
"What are you doing here, wait is that ink on your arm" Cassie said seeing the tattoo sleeve that went down to his elbow which looked like fish scales
"Oh yeah, it was Artur's idea, it kinds of matches his" Izuku said blushing
"It matches your dad's as well right" Cassie said
"Yeah" Izuku said
"Back to the original question, what are you doing here Izuku?" Cassie asked
"Something was thrown into the ocean after this island passed me while I was floating in the water" Izuku said
"Oh yeah you went back to Atlantis for break didn't you" Cassie said
"So what is going on here?" Izuku asked
"This is I-Island, a manmade island where ten thousand scientists live and work, most of them conducting research in relation to quirks so they can make better support equipment. It provides the scientists a safe location to collaborate and work on their research" Cassie explained further
"But who built it?" Izuku asked "And why did they think it was a good idea to move"
"It's what makes it a safe location, duh; can't kidnap anyone if the thing is always moving" Kara said
"Tell that to Atlantis" Izuku said
"Oh crap, we're in Atlantean waters aren't we?" Cassie groaned
"Close to it" Izuku said before a boom tube opened and Cyborg walked out
"Everything okay?" Cyborg asked
"Just fine" Kara said
"Izuku, I didn't think you would be here" Cyborg said
"Well someone dumped a robot into Atlantean waters and I came to investigate" Izuku said making Cassie glare at Kara
"What?" the blonde Kryptonian said
"Anyway, since you're here I'll give you a pass" Cyborg said as he scanned Izuku's face before he produced a holographic identification card and handed it to Izuku That will give you all access to the island just in case you're needed. But since you're not rostered on go and have fun" Cyborg said
"seriously?" Kara asked
"What about Nightwing?" Cassie asked
"He gave his okay when he learned that Izuku was here" Cyborg smirked. "Now I have to check on someone"
"Who?" the teenagers asked
"I'm Melissa Shield, nice to meet you" the person the group went to see said smiling
"Same here, I'm Cyborg these are Wonder Girl, Supergirl and Aqua-Knight"
"Aqua Knight as in the hero student who ended the war?" Melissa asked "It's amazing to finally meet you" she said
"Nice to meet you too" Izuku said
"And I can't forget you two as well" Melissa said hugging both of them
"Hey Mel" Cassie said smiling
"Hello" Kara said
"She's the daughter of David Shield, who was the support technician of All-Might when he was studying in America" Cyborg said "So how is that coming along?"
"Very well, my father and I have nearly finished it" Melissa said
"What?" Kara asked
"A secret project commissioned by Wayne Enterprises" Cyborg said
"Wait Wayne?" Cassie asked
"Yeah" Melissa said
"But why, unless he's still continuing that" Kara said
"But it didn't work" Cassie said
"No, he was stopped, but here on I-Island" Kara said frowning
"He still continued, what else has Wayne Enterprises here" Cassie said
"Anyway, I need to catch up with Nightwing, maybe you should show Aqua Knight around the island" Cyborg said
"Sure" Kara said as she was now uneasy at what was happening
In the ocean Aquaman was floating there watching as I-Island passed
"That thing has been here for the past five days, what is it?" Aquaman asked as Mera was with him
"A floating manmade island where scientists do research" Mera said
"I see" Aquaman said "still something's not right"
"What do you mean?" Mera asked
"Call it a gut feeling, and right now I bet Izuku is somewhere on there right now" he growled
"Shall I go see?" Mera asked
"No, I'm going back and then check in with the league to see if they know anything about this" Aquaman said
"Yes Arthur" Mera said
"This is incredible" Izuku said "Hard to imagine this is a manmade island"
"I know, being here has allowed us to think of things no one ever has" Melissa said as they saw a giant hero stomping past "We also have all the facilities of a large city"
"Such as an amusement park?" Kara asked
"Scientists get bored same as us, plus I'm pretty sure there are teenagers here" Cassie laughed
"Oh we should check out the pavilion over there" Melissa said
"Could be fun" Kara said. Once inside the four teenagers were awed by the different types of technology
"Oh wow, this is the Beagle, the first air to underwater vehicle" Melissa said
"Impressive" Cassie said
"Then this is a helmet which allows you to see various sensors" Melissa said
"Is that my hair from the back?" Kara asked looking at her hair in the helmet
"Not bad huh?" Melissa asked as they explored before Cassie stopped "Every item here was made to help heroes around the world with their work"
"You go to school here don't you?" Kara asked as the trio stopped in front of a giant mech
"Yeah, while I'm a third year here I still have a lot to do" Melissa said
"Including making a duplicate of a suit of power armour belonging to one of our enemies?" Cassie asked
"What do you mean?" Melissa asked
"I mean that" Cassie said showing a black power suit making Izuku shocked and angered, so he turned on Melissa and glared on her
"What is that?" Izuku asked
"An armoured dive suit" Melissa said
"Where did you find it?" Izuku asked
"It washed up on sure, why?" Melissa asked
"Because its identical to the one worn by a terrorist who calls himself Black Manta" Cassie said
"Black Manta, this is his suit" Melissa panicked
"Wow you think it looks like his" Mei said
"Yeah we do" Cassie said "MEI!" she exclaimed in surprise upon seeing the energetic inventor behind her
"What are you doing here?" Izuku asked surprised
"Oh that's easy I'm working on some new babies, though I'm quite surprised that you think this on is Black Manta's suit" Mei said looking at the suit "I call it the Sea Shadow armour"
"Sea Shadow?" Kara asked
"Yeah, The Sea Shadow Armour is the generation is underwater combat ability with activate camouflage, Sonar mapping, built in heating for freezing climate and an oxygen supply that can last up to twelve hours" Mei explained
"And who sponsored this?" Cassie asked
"Oh It was made by Hatsume Engineer who works with the Yaoyorozu Conglomerate" Mei said
"Wait Yaoyorozu, you mean?" Izuku asked before turning around and seeing his girlfriend there
"Hello Izuku" Momo said shyly
"Momo" Izuku said
"Someone want to fill in me?" Kara asked
Meanwhile over the ocean a helicopter was making its way to I-Island
"Are we sure it's there?" a man asked
"It is sir, I've asked one of the lead scientists on the project and he has confirmed its there" his secretary said adjusting her glasses so the man could see himself briefly
"Excellent" the man said smirking
"But there is also a presence of a Justice League team" the secretary said
"Oh well we planned for that didn't we?" he asked as his helicopter landed on I-Island.
