Ben had flew towards the sound of the explosion, once he got to there he found a large fire. Acting fast he turned into Omni and blasted water towards the flames. Everyone had caught sight of him saying "woah who is that hero?" "Never seen him before" "he new or something?".
Ben had gotten confused, 'Hero? Does this world have super heroes?' He thought. Then saw a guy made from wood jump out of a burning building carrying tons of people. A man with a fire men's theme blasting water from his tap hands. And a giant woman stuck between two buildings.
"Hey you!" Ben heard he looked down to see a large and bulky man "who are you, you a hero?" He asked. Ben flew down and landed right next to him "yeah I am, but right now we need to stop this fire" he said. The large man nodded then a scream sounded, a boy with green hair had ran into the fray.
Omni turned his legs into XLR8's and ran towards him, when he was nearing he spotted a kid trapped in some sort of slime monster. The green haired boy had ran to save him, the blob tried to hit the kid. Only to be poked in the eye by the greenette's bookback and he began to dig the trapped kid out.
Ben had charged in and released a sonic scream which had managed to make the slime monster come off the kid. Ben then blasted the buildings that were on fire with Big Chill's frost breath to extinguish the fire. "Hurry get him out and run!" He said blasting. The monster this time, "ack!!! Oh yeah, let see how you like getting blasted!!" The slime creep said. The hand that had been covering the trapped kid's own had rose up and blasted an explosion towards Ben. The shapeshifter grew two more arms and turned them into Diamond head's and shield himself from the incoming blast.
"Okay well let's see how you like this!!" Omni had emitted a green gas and on contact the slime creature hardened and started to crack. "WHAT!?!?? WHAT ARE YOU DOING TO ME!!" It screamed as its body chipped away.
"Simple that gas I got you with turns any form of gooey material solid, right now you're starting to solidify and like mud crack apart loosing your moisture" Ben answered. He then grabbed the trapped kid's arm "okay kid, help me out here and pull your friend out" he said. The green haired boy gasped then nodded and both tried to pull him out.
"I'm still not giving up without a fight" the blob said pulling the boy into him more, the kid managed to get his mouth free and yelled trying to get out. "Come on, already!" Ben yelled, that when a large, tanned, blonde, smiling muscular man jumped in, he grabbed the kids' arms.
"Okay buddy, I saw your powers, on three I want you punch this thing with me. Got it!" He said Ben smirked then nodded, "DELAWARE!! SMAAAAAAASH!!!!" The blonde hero said. Ben turned his arm into a hybrid of Four arms, Rath, Atomix and Armadrillo's and punched the monster with an uppercut.
This had resulted in the creature getting blasted to bits and a large updraft was created. "Woah" Ben commented on the combined strength of him and this hero. "Woah do you see what I see?" A spectator asked, Ben looked around then felt a raindrops on his head.
He looked up to see a large swirling cloud in the sky, "wait did me and him change the weather with that updraft?" He asked. All the people then cheered on them, a few reporters rushed in to interview Ben as he turned to human. "Pardon sir but what is your name!?" "What is your quirk!?" "Do you personally know all might!?" They all asked.
Ben transformed again and released a green gas that seemed to calm them down. "Okay okay one at a time please" he said in gutrot's voice, "now can you please answer some of my questions and I'll answer yours. That fair?" He asked.
They nodded, "okay now first question, you" he said pointing to one reporter. "Okay what is your name" he asked, "well the name is currently Omni but my real name is Ben Tennyson" Omni answered. "Okay now you, real skirt", the reporter then asked "where are you from?" She asked.
"Ever heard of the multiverse theory? Basically the possibility of endless universes where one thing in the world happened differently and numerous possibilities that could've happened did happen in a different time line and created a parallel universe." Ben explained. That happened to be very complicated and confusing but they did get the gist of it. "Yeah well I'm from a different universe, and yes I am also a super hero. Now you over there with the bull horns".
"What is your quirk?" The horned reporter asked, "let me ask a question now, what in the world is a quirk, I do t think we had those in my old world" Ben stated. "A quirk is a special characteristic that someone gets. If your quirk is super powerful it gives you a special super power and you can become a hero".
"Oh then I think we do have people like that but a small amount of of people" Ben said, "and I don't have a quirk, my powers come from this" he pointed to the Omnitrix. "This device gives me the capability to shapeshifter into various alien species. But recently it only has one all powerful transformation, which I am using right now" Ben then turned back j to his human self.
"Wow, aliens" Ben then put up his hands and flew off, tired of answering questions. Right about now he landed on a street light, looking down he saw the green haired boy from earlier. "Hey buddy" he said jumping down, the kid turned to see him. "Oh yeah? Wait your that hero from earlier" he said, "yup names Ben Tennyson, and you" Ben said.
"Oh Izuku Midoriya, thanks for helping me save my friend Ka-chan back there" he said. "No prob, besides it's what heroes do, save people no matter what the cost" Ben said, "besides, you deserve some credit to, I saw you run into that. It takes guts". Then out of now where that bulky hero from earlier showed up again. "I AM HERE!!!" He announced, "Aaahh huh All Might, where did you come from?" Midoriya asked.
"How did you get rid of the reporters?" "Ha ha, I stand for justice, not sand bites, because I am All Might!" He then deflated coughing up blood. "Woah, hey are you okay?" Ben asked concerned when he saw the hero's other form.
Smaller, weaker, skinny and frowning "any way I'm here to thank you, and to discuss your question from earlier" All Might said. Ben cocked a brow, as it turned out Midoriya was the hero All Might's biggest fan. And he didn't have a quirk, and All Might also used to be like Midoriya. His quirk wasn't his, it had been passed down to him from another hero.
Then All Might explained that when Midoriya charged in to save his friend, it inspired the pro to act. Ben had felt respect for Izuku, no one would've done something that dangerous knowing the consequences.
And for the next few months Midoriya had been training, All Might had said that he was worthy of inheriting his quirk. Ben had helped him in more combat based training, while training his overall strength All Might had Midoriya clear and entire beach littered with garbage.
The reason Ben had helped Izuku with combat based training was because Midoriya showed promise in fighting but because he was gaining a potential lethal power. The shapeshifter decided to teach him useful alternative fighting moves. One being revonnah kai, the martial art of Rook's home world.
Ben picked up on one of his visits to Revonnah, along with his former Revohnnagander form named Cat fu. Little to say Izuku had little problems fighting, especially since now he can crush rocks with his new martial arts.
On the last day of training Ben was heading to the beach All Might had Midoriya working on. The blonde hero in question had arrived when he did, "hey All Might, I see you're here as usual" he said. All Might, in his weaker form, responded with "yeah, like every day since young Midoriya's training,
"So why are you here?" The hero asked the former hero, "just checking on him, speaking of which wasn't there more trash here?" Ben asked. Then out of nowhere they heard a loud battle cry, looking to the source they found Izuku standing on a large pile of garbage.
"Holy" All Might said, "God, he... he didn't" Ben said equally stunned. "Holy stinking SUPER CRAP!!" All Might said in complete amazement while in his hero form. "No freaking way!" Ben yelled, Izuku then fell off the pile and into All Mights arms.
"Kid, look" he said, "dude nice" Ben said, "hey guys did I do it!" He asked slightly waking up. "Did you do it, far from it, you even went out of the section of the beach I told you to clean. You've exceeded my expectations young Midoriya, YOU WENT BEYOND!!!!!" All Might yelled.
"Not to mention your training, I knew you were improving in your fighting but this is unreal. This is, incredible" Ben said.
Not only that but the resulting training had made Izuku physically stronger and appear so as well. "Well done young Midoriya" All Might said, Ben then smirked.
'Looks like he's gonna get his wish of becoming a hero after all' he thought? 'And I am so gonna be back in the job' he added.
