Allen a teenage boy trained in A secret martial art wakes up in my hero academia as a saiyan now to learn to control his powers he must go to UA after being persuaded by Otohime watatsumi there he plans on training to become a hero using his knowledge of his martial arts.
Allen was returning home from his dojo after training in Raijin-ryu kenpo he was about to enter his house when a strange bolt of lightning hit him and he felt his body change.
Oh shit said the lightning god susanoo I killed a boy I must make up for this quickly I shall give him the body powers and abilities of a saiyan and I shall send him to my hero academia also so he doesn't become a freak he'll be fourteen when he's resurrected.
Allen woke to find himself staring at a woman with reddish orange hair
"Are you alright." She asked.
"Yeah I'm fine."I said waking up I found I was still wearing my kenpo gi but also I had a tail my hair was black instead of red my eyes were black instead of green and my body was more sculpted with muscles.
'No I'm not alright I'm a saiyan'
"Then I noticed who I was talking to the girl was Otohime watatsumi."
Well as long as you're alright she said suddenly a group of bad boys came over.
"Hey hot stufff why don't you ditch that loser and spend some time with us." Said the lead boy who was a big brutish boy.
"No thanks I'm not interested."said Otohimé
"Come on baby." said the boy
"look what I can do." he then created vibrations in his hand that when he threw his fist created a shockwave.
Then he turned to me and tried to punch me with said vibrating fist but I caught his arm and with using leverage through my hip I threw him to the ground.
He got up "you punk!" he came at me but I suddenly glowed with an aura and with my arms containing a burst of energy I struck him in the chests and knocked him into the wall using a sweeping right hook and a spinning elbow smash.
The boy spat blood from the power of my blows as I finished him off with double circle kick.
The other boys were about to attack when Otohime released an aura that made them piss their punker pants.
She turned to me and said "what's your name."
"Allen Tachibana." I said
"i'm otohime and i want to reward you so i'll give you a personal invitation to U.A Academy"
and so our story begins
