(Alright i watch a video called what if deku was a evo and thought why not just add rex.few things about how rex power work in this what if

Quirk name:nanites

Quirk type:mutant

Description:the users of the quirk are born with tiny microscopic bio machines. They give them a high durability,weak healing factor,ability to control/repair technology,and in rex case build them.

Weakness:if the nanites are over used they will go into what know as a cooldown.where the users are quirkless until they have enough time to rest then the nanites start back up. The use can make the nanites over work pass cooldown but that cause nanites to explode. also with a few of the build can make the user vision blurry

Caesar and violet will be quirkless,rex get his power from his dad. Both his father and mother are both ceo of a powerful hero item support company. move to Japan when ceasar was born as japan has the lowest crime rate in the world

With that said enjoy the cringe)

Rex had always wanted to be a hero. This was due to the fact the number one hero all might saved him. When rex was seven from some villians that wanted to get money off of rex family.His family supported rex but also told him that he should think about join the family business. Think on how a parent supporting their kids in becoming actors.Rex never thought he could be a hero. Until the day everything changed.

Rex on this day was in his last year of middle school. He would be walking home from school with a friend. Two Villian would rob a store running out of it. The two of them were being chased by a hero. They saw rex and his friend. They ran up to them and grab them. Both point their guns at rex and his friend. "anyone come any closer and we will blow these kids heads off",said one of the villains. It was as if time had slow down for rex. He was seeing his friend in danger. The heros and cops being to worry to do anything. He was scared for his life. adrenaline starter to pumping threw his vines as he scream. Rex wish he was a lot stronger to escape"LET US GO NOW",said rex. His nanites reacted to all this. his hand glow with a blue panel line pattern making a pair of mechanical fist the smack hands. The villian holding rex lose his grip on rex. Rex turn to face him upper cutting knocking him out. The other villian points his gun at rex shotting at him. Rex blocks the bullets with the smack hand.The villian run out of bullet and throws the gun at rex then runs off. Thankfully the hero originally chasing the villian pair, Was able to catch him.Rex smack hands crumb down as he passes out due to shock.

Emergency responders show up as they take rex to the hospital.A few hours later rex wake up in a hospital bed. His parents both sitting next to him ,and Ceaser standing next to them. Both parents pull him into a tight hug."man what happend to me my head killing me ",said rex"well you were in a villian attack they said you made giant first and beat up the villian them pass out ",Rafael (rex father)explain.Ceasar look closer at rex " fascinating they do say quirk get stronger each generation so the stress must have activated this hiden ability in him",said ceasar"all that matter is that our little boy is safe", said Violet(rex mother)"im not a little boy mom",said rex with some annoyance in his voice.He look down on his hand making fist smiling. He now had hope that he can truly be a hero. A police officer show up to get some answers. Once that was done and rex seem to be able to walk. He would be discharged and able to go home.

Rex and his parents would all get to Their really nice house. Violet and Rafael told rex to rest up. He listen and went to his room,or so they think He wanted to learn more of what he could do,so he called up his ceaser.

Before rex said anything ceasar knew what he wanted."let me guess you want to know more on what you can do",said ceaser "how did you-",said rex before interrupted by Ceasar"know were brothers plus I want to know more as well come to my lab and we'll do some testing-" rex cut ceaser off and said "and training".Ceasar was taking a back by rex statement "what do you mean",ceaser question."ceasar you know I always wanted to be a hero this is my shot the ua entrance exam is six month away will you help me",said rex.Cesar sights"the thing I do for you little brother okay come to my lab and we'll start",said ceaser "yes thanks you",said rex with enthusiasm in his voice.Rex hangs up the phone. He runs out of his room and goes down stairs. He runs to the door. Putting his hand on the door,and being stop by his parents."woah where are you going", question rafael"im going to go hang out with Ceasar I'll be back by dinner time",said rex in response. Both of them sight in frustration."fine but please stay safe",violet said in a mix of frustration and care."i will dont worry",said rex as he left the house.
