Deku the One For All Legend (Bnha multi crossover fanfic)

UA Sports Festival

    It was the day before the sports festival and all the UA students thought they should get some rest before the big event.
Izuku and Toshinori were sparring on Beerus's planet. They are both able to use 990,000 percent of their quirk. Izuku was built like base form Vegeta and a tiny bit taller than him too. Toshinori didn't look too different from before. Although, now when he uses One for All at the percentage he's able to he has yellow lightning crackling on him.
Izuku was very close to learning Ultra Instinct and both are also getting close to contacting the Saiyan God Yamoshi!
"We've both gotten pretty strong aye young Midoriya?" Toshinori said.
"Yeah! I wonder how powerful Yamoshi will make us!" Izuku said with excitement.
"Hard telling young Midoriya." Toshinori said.
"Alright you two. I think that's enough training as of right now. Izuku needs to rest before the Sports Festival and you need to be there as well Toshinori." Whis said.

Meanwhile at the Central park in Japan.
Lucas had decided to meet up with his friends back here after texting Izuku, Goten and Artih and to bring Trunks and Mina as well. Ochako and Eijiro were with Lucas seeing that they trained with him.
Izuku, Goten, Trunks, Artih and Mina all arrived at the park to see their friends Lucas, Eijiro and Ochako.
"Hey Deku! How was your tra-..." Ochako was cut off by seeing Izuku's shirt being tight around his new found muscles. Her eyes went wide and blood splurged out of her nose from the sight knocking her out.
"Uraraka! Are you okay!?" Izuku asked worried.
"Holy crap Izuku! What did Whis put you through!?" Lucas asked.
"Yeah Midobro! You're downright ripped!" Eijiro said.
"Kiri!" Mina shouted running up to Eijiro hugging him tightly.
"M-Mina! Are you okay?" Eijiro asked in a bit of concern blushing at Mina's embrace.
Artih walked up to Eijiro and whispered in his ear. "Don't you dare die!" "Why would I die?" Eijiro whispered back.
"Just. Dont." Artih said.
Izuku was trying to get Ochako to wake up from her fainting and nosebleed.
"Bomb Shelter, I think she's gonna be out for awhile. By the way, you have almost the same muscle mass as my Dad, and the power level from you is just unbelievable! What the hell did Whis PUT you through!? It had to of been rough!" Trunks asked.
"You don't want to know..." Izuku said shivering at the thought of what Whis put him through.
"So, what all did you guys do in training?" Trunks asked.
"Well, Whis told me that i'm close to unlocking Ultra Instinct. I'm also close to unlocking a new specific power." Izuku said.
"Apparently i'm dragonborn." Eijiro said.
"What did you do Mina?" Eijiro asked.
"Well... I learned how to go Super Saiyan..." Mina said.
"Yeah... she started learning way too quickly, right now I think she's my equal other than Lucas." Artih said.
"She is a Majin as well as a Saiyan, so of course she'd be a fast learner." Lucas said.
"Mina! You can go Super Saiyan!? That's so manly!!!" Eijiro said with starry eyes.
'If only you knew how Kiri.' Mina thought holding her tears back.
"Kiri... can I talk with you in private?" Mina asked.
"Um... sure Mina." Eijiro said. Mina and Eijiro walked off out of earshot from the others.
"What do you think they're gonna talk about?" Lucas asked.
"Lucas, I know I call you stupid but I know you're no where near stupid. YOU CAN LITERALLY READ THEIR MINDS!!!" Artih said backslapping Lucas.
"OW! Okay okay! Jeez!" Lucas said.
"Of course, don't read their minds, it might be something private. I think she's gonna confess to him." Artih said.
"Wait, Ashido likes Kirishima?" Izuku asked still holding onto a knocked out Ochako.
"Oh yeah! It was officially obvious when she first went Super Saiyan after I told her she was too weak to protect him at the USJ and could've died if you didn't save him." Artih said.
"Really? What did she look like?" Izuku asked in curiosity.
"She literally looked like a golden haired demon... it was scary... and she beat the absolute shit outta me. She thought she killed me and honestly, I thought she was going to as well." Artih said.
"Jeez! Just how powerful is she!?" Lucas asked.
"Very... I gave her an illusion potion and a punching dummy... she went Super Saiyan 2 and... I don't even want to talk about what I saw..." Artih said.
"What did she do!?" Izuku asked.
"She literally obliterated that dummy..." Artih said.
"Damn!" Lucas said.
"Aaaaaannnnndddd their kissing over there." Artih said.
"Welp I guess she confessed to the dragonborn." Lucas said.
"Did you really give him that celestial book based on one of your favorite video games?" Artih asked.
"Verin told me to." Lucas said pouting.
Unbeknownst by Izuku, Ochako woke up still in Izuku's arms bridal style. After she fully awoke she then realized the position she was in.
'OH MY GOD I'M IN IZUKU'S ARMS! HOW DID HE GET SO MUCH MUSCLE!? HIS SHIRT IS SO TIGHT AROUND HIM AAAAAAHHHHH!!!!' Ochako thought having her mind go one million miles per hour.
"Hey Izuku, Ochako's awake." Lucas said laughing.
"Oh! Uhhh, s-sorry Uraraka-san! I just saw you fall over and didn't want you to get hurt." Izuku said putting Ochako on her feet. Her face is heated up so much that steam came out of her ears.
"U-uh, i-it's okay D-Deku." Ochako said stuttering trying not to have another severe nosebleed.
'Well we got the ship queen and the dragon scaled knuckle head together, now we need to get muscle broccoli and the floaty sorceress together... great, now Mina is starting to rub off on me.' Artih thought.
"Anyway, Bomb Shelter! Let's see how much power you have now!" Goten said excitingly.
"Are you sure?" Izuku asked.
"Yeah! We want to see your full power!" Trunks said.
"Well okay... if you insist." Izuku said.
After that, Izuku floated in the air, his hair started flowing upwards and after that, grean lightning appeared and Izuku erupted in a green aura having his hair glow looking like a Legendary Super Saiyan with his eyes fully glowing green. They could've swore he was Broly's secret love child! (Although Broly sees Izuku as a brother. I saw the chance and took it).
Mina and Eijiro came back to the group to see Izuku showing off his power. All of them were in awe at the sight.
Izuku powered down and floated back to the ground.
"Holy shit!" Lucas said having a loss of words.
"And I thought Mina gotten powerful!" Artih said.
"I don't think Katsuki realizes who he's calling his rival." Goten said.
"I agree one hundred percent!" Trunks said.
"Alright, why don't we head home and rest up for the sports festival?" Mina said.
"Alright, well see you guys tomorrow!" Izuku said.
As everyone was saying their goodbyes they all left to go home.
