Basically if you played final fantasy xv then imagine that battle for Shiva but the rest are the other final fantasy battles.
Izuku's P.O.V. 10yrs later
I had just completed training all that was left for me to do was to take a leap of faith. When I took the leap I felt free I felt brave I felt as if I could do anything then I landed in the water. 'Thank god aunt Shiva and aunt Siren taught me how to swim' I thought.
"Well done Izuku you have been doing well in your training but here is a workout schedule so you don't over work yourself for when you get into U.A." my dad said he then added "come on let's go get some ice-cream" with a smile on his face while looking at me.
"Ok dad" I said while showing a smile of my own I thought it was a little funny when they all muttered to bright.
We made it to the ice-cream store and we bought our favourite flavours for me I had mint chocolate chip but my dad had raspberry ripple. We headed through the park and I saw my sister with other people bullying a girl with a frog like quirk.
I handed my dad my ice-cream and speared the spiky ash blonde haired boy. I then knocked out a boy who was perving on both my sister and the frog girl. Then a blonde haired boy with a black lightning streak in it asked "who the fuck are you to ruin our fun loser?" "IZUKU?" My sister yelled.
This caused her friends and the injured girl to freeze up. I sprouted my wings and allowed my horns and eyes to show. "Look that girl *points to the injured girl on the floor* is under my protection so LEAVE HER ALONE!!" I semi-yelled at them.
"What happened to you we were worr-" I cut her off "don't lie to me you left me a four year old boy to walk for three hours all the way home on my own" I said with each word dripping venom that scared her.
"I will never forgive you" I said then I broke blonde boy's jaw with a quick punch. "You don't deserve to be a hero so leave and give up on that dream" I told her she just ran home crying with her conscious friends following which were a boy and two girls the boy much like one of the girls had both red and white hair while the other girl had spiky ash blonde just like the boy I speared.
"It's ok your safe now" I said as I turned back. Just then All Might showed up. "What happened here I was told that there was a villain in the area?" He said. "That's not true sir" my dad said as he then explained to All Might what had happened and explained what the culprits looked like as well as give him the adresses I summoned my aunt siren and asked for her help to patch up the frog girl to which she agreed.
"Izuku right?" All Might asked me to which I just nodded yes "meet me at this address tomorrow along with your new friend here we have something to discuss" he said my dad of course was allowed. Then All Might left.
"Right let's go take you home" I said. "I can't" she said this now peaked our interest "what do you mean?" I asked. "I was kicked out because my quirk is a frog mutation quirk. "AWESOME" I yelled. "Hey dad she's coming with us ok good" I said in a mix of joy and excitement.
