All Might:I AM HERE IN AN NORMAL POSITION"
Inko: and so am i in a totally normal position
as all the students were ecstatic of his arrival Izumi looked at everyone happy they loved her dad but when she looked at her brother she found that he didn't care whats so ever yet in his eyes it showed rage and then All Might"said today we will be doing pokemon battle training so prepare yourself but whats a pokemon master without her and his suit"then All Might pressed a button and walls opened revealing isles of cases filled with there suits "battle" said Katsumi with a smirk "training" replied Izumi as everyone got there suit they saw Izuku get his and wondered what it was then Izuku was walking towards the door but was stopped by Inko"Izuku I"but before she could finish Izuku walked and bumped into her shoulder then exited the room All Might was secretly snickering in joy he secretly set up the training so Izuku could get hurt by his opponent. No one had ever seen Izuku that way what relationship did he have with All Might and Noivern they all wondered as Izuku left the room completely silent and he stayed that way till everyone began to walk in the room when they saw All Might standing with his arms crossed and Noivern trying to talk to Izuku but young Ketchum ignored and walked to the wall and leaned on it "hey Ketchum you okay"asked Kirishima Izuku smiled at her and placed his hand on her head then ruffled it making her blush"i'm fine thanks for asking "he said everyone smiled knowing the kind boy is still there but then the class began.
All Might :young Yagi were is your suit
Izuku pissed:hey anyone know Izuku Yagi im Izuku Ketchum
Noivern looked in shock( but not for Izuku saying his not a yagi but for his new last name and you'll find out why later )then Izuku said"oh I forgot my suit okay then one sec"
Izuku came back and people stared in awe
Uraraka was pissed but Izuku didn't care after 10 minutes of discussing what were doing the teams were announced Izuku and his pokemon Greninja ended up with Uraraka and Sylveon against Dilila and her pokemon Jolteon and lilly and her pokemon decidueye .Izuku beat them alone since Uraraka tried defeating the team alone and lost in which he got stuck with all the work. Then it became the final match but it was Shoko vs Yagi and Bakugo Izuku couldn't just stand by and let that happen Izumi and Bakugo left to prepare.
Izuku:Im teaming up with Shoko
All Might:you are why
Izuku: because it isn't fair
Shoko:Ketchum me and Nine tails(alolan) can defeat them alone
Izuku:LIKE HELL i'm fighting with you thats it right Lycanroc
Lycanroc:Ly Lycanroc
Shoko and nine tails were blushing and looking down
Noivern:You already battled two on your own you should rest
Izuku: come one Shoko"Izuku grabbed her hand and began to walk away with their pokemon following
Inko:I am your mother don't you care what I saw.
Izuku: SERENA YVONNE IS MY MOTHER and besides if you fell of a bridge I still wouldn't call you that and the fact you were my birth mother makes me want to kill myself to be related to someone like you is a fate worse than hell.
Lycanroc:ly ly lycanroc hmph
Izuku: thats right partner
Izuku left leaving everyone in shock but Shoko was worried"Kethcum what did she mean by she is your mother and if you dont want to talk about it it's fine"she said Izuku looked back and said "don't worry I'll tell you someday"she smiled an real smile something she hadn't done in years Izuku was happy to see her smile .Once they arrived they prepared themeselves"Shoko I'll fight bakugo knowing her she is probably waiting to attack me you fight Yagi kay"Izuku explained she nodded and All Might said go the two charged into the arena and Bakugos Infernape charged at them screaming Izuku pushed Shoko out the way and told her to go against Izumi she nodded and went into the other arena "well Bakugo it's you and me"
Infernape charged at Lycanroc"INFERNAPE USE ACROBATICS"
izuku:LYCANROC USE COUNTER"
Lycanrco used counter and sent Infernape flying and slamming into the wall
Izuku took a sigh of relife then he and lycanroc saw a pillar of fire and a screaming Infernape and Katsumi"WELL KILL YOU USE EMBER AAAAAAAA"she shouted as Infernape did as told
the fire hit Izuku and Lycanroc exploding on impact and blowing everything up shaking the entire arena as the smoke cleared out Izuku could be seen infront of Lycanroc hugging it protecting it from the blast his entire back was covered in class 6 burns his back was still smouldering.
In the watch room
Inko:My baby
Kirishima:so manly
Momo:my god look at his back whats so femanly about that
Kirishima:well for one thing he protected his pokemon since they weren't ready for that attack and that was dangerous but he put his pokemon above himself now that is a trainer spirit.
Back in the arena
izuku fell down on his back smoking Lycanroc looked down"haha you see that is power you weakling "Katsumi said but then she got a look of terror when lycanroc looked at her in anger it's eyes were read and he looked ferocious
It ran to Infernape at blinding speed"infernape use"but before she could say anything
sending it into a wall then forefully using it's Z move it jumped in the air and used Continental crush
he destroyed the entire arena shocking everyone with his power and as the smoke vanished they could see Katsumi and her Infernape in the ground knocked out with their eyes at the back of their heads. Lycanroc went forward to hurt them more but it stopped feeling hands wrap around it it looked and saw Izuku"it's okay pal now help me to Shoko okay"Izuku said smiling Lycanroc nodded and licked Izuku then helped him walk to Shoko. Izuku Midway put Lycanrock back in his pokeball then brought out Greninja as soon as Izuku found her she was stuck in the ground with nine tails awake but not moving and when he looked closer they saw her burn marks around the two and they were in pain meaning Izumi and her pokemon Blaziken were the cause Izuku looked and saw his sister with Blaziken their arms were crossed "so then ready bro"she said as he smirked"always
Izumi:THEN LETS DO THIS BLAZIKEN
Izuku: GRENINJA
Greninja /Blaziken:GRENINJA /BLAZIKEN
the two ran at eachother and began fighting blaziken using kicks to attack and it's arms to defend ,and greninja getting the upper hand in both defense and offense kicking blaziken around and punching it in the gut sending it flying it back flipped and landed crouching
Izumi:BLAZIKEN USE BLAZE KICK
blaziken ran at Greninja using blaze kick to kick over and over again but greninja blocked all it's kicks
Izumi:now roundhouse kick him
izumi:and then high jump kick him
she shouted as Blaziken kicked greninja mid air sending it crashing down then as the dust dispersed
Izuku:GRENINJA USE QUICK ATTACK AND ARIEAL ACE
Greninja rans o fast it vanished and then reappeared over Blaziken axe kicking it's head slamming it into the ground
Izuku:now pick it up and toss it in the air then USE CUT
Blaziken began falling from the sky only to be hit with a water shuriken sending it slamming into the ground creating a massive commet .Blaziken walked out nearly collapsing and so did greninja the two thought of their trainers and got a massive boost of power
Greninja:'ever since i was born Izuku was there training me he never left i lost so many battle i was always so weak and when i would lose he stood there he looked at me and smiled why why why why did you smile master no farther i love you with all my heart and i refuse to lose i will win i will show you all the work you've put into me is not waisted

Timeskip
Izuku had woken up from his slip only to see Izumi looking outside
Timeskip again
Katsumi and Uraraka came walking in and then they stopped Katsumi pulled uraraka to the side behind the wall and looked in Uraraka wanted to scream in anger and so did Katsumi Izuku hand was at the back of Izumis neck and their foreheads were touching with their eyes closed "grow stronger Izumi and then when i see you've become the absoulte strongest you and your pokemon are capable off i'll use my strongest pokemon Charizard till then catch you later"Izuku said walking away not noticing the girls hiding .
