Smash Brothers Hero

Stow Your Fear

Izuku was a five year old boy walking home from elementary school, but his notebook, and hero journal were turned into toast by Katsuki Bakugo. A nightmare child and bully, little did Izuku know, he was about to be jumped by the demon child. When Katsuki was about to jump him a blue beam of light enveloped him. Bakugo was to scared to try anything and ran away with his lackeys. When Izuku realized he wasn't in his world he went wide eyed. He was actually a very confident kid, but it's easier to just get laughed at for being a weak and scared nerd. He got in a fighting position and waited. When he heard a slight sound he uppercutted the area it came from.

It took him a while to realize he had punched a plumber in red. The plumber stood up and rubbed his jaw while saying, "You've got one hell of a punch, I'll give you that." Izuku didn't stop, he was still ready to fight. He wasn't going to go down easily, when he heard singing he wanted to fall asleep, but he wouldn't let himself. He stayed in his fighting position and didn't seem the least bit drowsy. In fact what surprised everyone was how he punched the pink puff ball in the face after that and sent it flying. They heard him mumble, "I may be quirkless, and I don't care how strong yours are, but I'm not going without a fight." He stuck his ground, and even jumped at a giant purple dragon. He punched it three times before hopping on it's head and kicking an orange dragon in the face. He took a blue fire ball called a Hadoken to his body, and tackled a strong guy in an orange gi.

Once he had pinned the muscle guy he said, "Where am I, who are you, and when can I go home." That was when an entire cast of people came out of the shadows. Some notable ones were a gorilla and monkey, a fox, falcon, bear, fully armored person, turtle dragon hybrid and eight smaller turtle dragons in floating clown cars. Izuku just readied himself again and said, "I'm already pissed off because of school, so if any of you want to test me. Do your worst, I won't loose! I will prove I can do anything, even if I die trying, so come on!" A short guy with green boxing gloves came out of the crowd and said, "I like your style, show me what you can do." Izuku smirked and charged before side stepping a punch and kneed the guy in the stomach, the guy flew to the other side of the room and Izuku whispered, "Training pays off apparently." He seemed to have surprised the entire group and even the punching guy.

He heard a feminine voice say, "Now I know why he showed up, but I don't think he's a combatant." He heard another, more stern voice say, "You are right, but then why is he here?" A giant hand appeared out of thin air and answered the one person, "Simple, he's to be trained under you. I gave him the ability to learn some abilities exclusively given to characters. Bayonetta, for example, can teach him witch time." He assumed he knew which one she was because of the shocked expression, but another gruff voice had to question it, "Why train him? What do we have to gain?" The hand spoke again, "You get to save a universe, his is domed to fall, and superpowers exist there called quirks. He was born without power, or quirkless. That makes him the perfect candidate to train."

Izuku noticed an orc, he assumed, step in front of him and say, "If he can take a warlock punch, then he is worthy." Izuku sat there and looked him in the eyes. He charged up a purple fist, and to everyone's surprise, Izuku caught it. The orc laughed and said, "Names Ganon, you are truly a strong willed and powerful kid. You are worth my time." Izuku smirked and said, "You learn how to counter certain things when you're constantly attacked." Everyone was kind of confused, what did he mean constantly attacked? Izuku noticed and stated, "As the hand said, I have no power, in a world where power is all that matters. That means I was attacked for walking the same direction as someone else. Yet I never faltered, it pushed me to work harder than ever before. I never lost my hope that I would save others with a smile on my face. I've stared death in the eyes, and it's never fun." Two guys with whips perked up when Izuku said the death part.

The same plumber from before stepped forward and stared at Izuku before saying, "Okay, so you'll learn from each of us." Izuku didn't know it at that time, but he would be the strongest person in his world. All Might would be the equivalent of a birthday party for him. He couldn't even call any of these abilities quirks, he learned to control fire from Mario and Luigi. He learned how to float midair from Peach and Daisy. Learned how to sumo slam someone, and create bombs and many other technological devices from Bowser and the Koppalings. Wario couldn't teach him much, so he just sparred with him. Same situation with Rosalina, Dr. Mario and Piranha Plant. Yoshi taught him the flutter jump. Donkey Kong and Diddy help him improve his strength and mobility. King K. just tested Izuku's strength.

All the Links taught Izuku powerful sword techniques. Zelda taught him to use Dins Fire, and teleport. Ganon taught Izuku the flame choke, and warlock punch. Sheik just helped increase mobility and stamina. Samus taught him how to make better judgments under pressure, and about technology. Ridley and Dark Samus just tested Izuku more. He was no slouch in his mental studies either. Kirby, Dedede and Ice Climbers showed him how to use a hammer like theirs. Meta Knight used his agility and speed, along with sword fighting skills to train Izuku. Fox, Falco and Wolf taught him close combat and how to pilot a majority of things. Picachu, Pichu, Jigglypuff, Greninja, Incineroar and Pokémon Trainer taught him agility, speed, stealth, strength, tactics and skill. Mewtwo taught him his psychic powers, and Lucario taught him to control aura.

Snake taught more stealth. Ness and Lucas taught him their PSI and PK powers. Captain Falcon taught the Falcon Punch, and dive. The Fire Emblem characters taught him how to counter with a sword, and how to control fire to a certain point. Mr. Game & Watch showed him how to quickly switch between powers. Pit and Dark Pit taught him to use a bow and arrow, while Palutena showed him a reflector, and he could surprisingly do it. Sonic was all about super speed, and Izuku could keep up with him for about two minutes before going slightly below Sonic's speed. Olimar was just about learning how to dodge small projectiles. R.O.B was another sparing partner, and taught about robotics. Villager and Isabelle were about peaceful negotiations so that violence hopefully wouldn't be needed. Mega Man was more robotics, and Izuku made a great set of armor that was loose until the center was pressed. Then it would conform to the wearers body.

Wii Fit was all about stretching and endurance. Little Mac taught a bunch of boxing techniques and strengthened Izuku up. The Mii fighters were practice with dodging, swordsmanship, and reflecting attacks. PAC-MAN was all about unpredictability, and Shulk was more swordsmanship. Duck Hunt taught him about teamwork. Ryu and Ken taught some of there techniques, like Hadoken and Shoruken, and Cloud was another swordsman. Bayonetta taught him witch time which was very powerful in more situations than one. Inkling was mostly marksmanship training. Simon and Richter were all about using a whip. Joker was more marksmanship, and Hero was sword fighting and Izuku learned some magics. Banjo was teamwork, and Terry was more hand to hand combat.

By the time he had mastered every ability, it was time for the entrance exams. Fifteen years of training, and he was off to the entrance exams. Everyone was sad to see him go, but he promised to visit.

(This is a story I had really enjoyed the idea of, and had been meaning to write for a while. It's just getting started and things are going to get a lot more interesting. As for the harem.)
