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

Training with Goku, Vegeta, and the Z fighters

The next day arrived and Izuku quickly jumped up out of bed and got dressed as Inko got breakfast ready to get ready for the day.
"Izuku! Calm down! You'll jump out of your skin with all that excitement!" Inko said handing her Son his breakfast.
"Sorry Mom. I'm just so excited! I'm slowly moving up the ranks to becoming a hero like All Might!" Izuku said excited.
"Yes Izuku I know! I'm so proud of you! You haven't given up your dream and proven to All Might that you ARE a hero!" Inko said.
As they ate breakfast, Izuku started to look like a chipmunk.
"Izuku, honey, I know you're excited but please, take smaller bites! You're gonna choke!" Inko said.
Izuku swallowed all his food and said "Sorry Mom."

After they ate breakfast, Izuku brushed his teeth and started to run for the door.
"Izuku!" His Mother yelled.
"Yeah Mom?" Izuku asked.
"I'm so proud of you! Please be careful!" Inko said smiling with tears in her eyes.
"Thank you Mom, and I will. I love you." Izuku said hugging her Mom.
"I love you too Izuku." Inko said hugging her Son back.
"I gotta go now, Goku is probably waiting for me right now." Izuku said.
"Okay, bye Izuku! Come back safe!" Inko said.
"I will Mom!" Izuku said as he ran out the door and out the apartment complex.

As Izuku went on his way to Dagobah beach, he sprinted using his ki and One for All and got there in an instant. He saw Goku waiting for him meditating on his flying nimbus.
"Oh! Hi Izuku! Since your not able to fly yet we'll be taking the nimbus. Of course, nimbus will only let those with a pure heart to ride him. Tell you what, I myself will fly and let you ride nimbus if he lets you on. Whaddya say?" Goku says.
"Oh, okay, I guess I can try to get on nimbus." Izuku said.
"Alright! Let's see if nimbus likes you!" Goku said picking him up and setting him on top of the flying nimbus. Izuku expected to fall through the nimbus, but to his surprise, he was standing solidly ontop of nimbus!
"Looks like you have a pure heart Izuku! Don't worry, nimbus won't let you fall." Goku said.
"Now, if you just follow me, there's a few people I want you to meet before we head over to the time chamber." Goku said.
"Really! Who are they?" Izuku said.
"My Son Goten, and his best friend Trunks. Ever since you made that heroic act four months ago, Goten and Trunks started to actually admire you!" Goku said.
This was the first time he heard someone actually ADMIRE him! Not just anyone though, it was the Son of who All Might claimed to be the strongest martial artist in the universe! He was not used to hearing this.

As they arrive at capsule corp, Goku walks in with Izuku behind him.
"Hey Bulma! I brought a visitor!" Goku shouted.
"Goku! You know how much my husband hates random visi-" Bulma was cut off by the sight of Izuku and let out a gasp of excitement.
"Oh! Oh my goodness! Trunks! Goten! Get in here!" Bulma shouts.
"What is it Mom! Me and Goten are playing super he- OH MY GOD! IT'S BOMB SHELTER!!!" Trunks shouts. To this Goten shot down the stairs at what seemed like the speed of light.
"OH MY GOD! IT'S BOMB SHELTER! IT'S REALLY HIM IN CAPSULE CORP IN THE FLESH!!!" Goten shouts as both him and Trunks fly up to his face shooting him with a million questions a second.
"BOYS! Boys! No need to get up in Izuku's personal space! Let the kid breath!" Bulma said.
"Awww but Mom! I want to know what it was like working with All Might! I mean even All Might praised him after he rescued that girl from that scary clown!" Trunks said.
"Well, I mean, you two already have what it takes to become incredible heroes! What are your quirks?" Izuku asked.
"Oh! We don't have quirks, we're just like you! We use ki control instead seeing that we're both Saiyans!" Trunks said.
"Yeah! We're gonna heroes like you one day Bomb Shelter!" Goten said.
Izuku was NOT used to such appraisal, he was bullied all his life and was called useless because he was quirkless. Not much by anyone else seeing that he keeps getting stronger, and more on the lines of just Katsuki bullying him trying to keep Izuku beneath him. He could only imagine how mad he would be after he goes back to school after the weekend.
"By the way, Goten, Trunks, i'm gonna take Izuku over here to train him with his new quirk that he got from All Might himself!" Goku said.
"YOU GOT YOUR QUIRK FROM ALL MIGHT!?!?" Both boys say in unison.
"Yep! With enough ki control he'll be even stronger than Krillin, maybe Piccolo!"
"Wow! That's so cool!" Goten said.
"Well, we better get going. Don't want to keep the others waiting!" Goku said.
"Alright, by Goku! By Bomb Shelter! Hey Goten! Let's spar outside!" Trunks said.
"Okay!" Goten said.
Goku used instant transmission to teleport Izuku to the time chamber. Izuku was surprised to see that Goku could teleport.
"Hey guys!" Goku said waving to Vegeta, Broly, Gohan, Piccolo, Krillin, Tien, Yamcha, Whis, Beerus, and Majin Buu.
"Well if it isn't the man, the myth, the legend, and the ninth holder of One for All!" Krillin said.
"How many know about One for All? I was told not to tell anyone!" Izuku said.
"Oh, just us, plus Goku's youngest son and Vegeta's only son." Tien said.
"Of course, all the Saiyans know about the quirk One for All seeing where it came from." Vegeta said.
"Wait, where did it come from?" Izuku asked a bit confused.
"I'll tell you later, we're gonna train you till you have the strength of a Saiyan! Got that!?" Vegeta shouts.
"Hey whoa! Vegeta let's not get crazy! I mean, not doubting Izuku here, but Earthlings have limits!" Gohan protests.
"With the quirk he holds, he doesn't need to worry about limits!" Vegeta says.
'He's like Kachan but actually believes in me.' Izuku thought to himself.
"That's the first time I heard Vegeta actually have faith in an Earthling to have the strength of a Saiyan!" Said Whis.
"Now then, put these on and meet us in the Chamber when your ready!" Vegeta says handing Izuku Saiyan armor that looks exactly like his.
