Izuku the legendary (discontinued)

Just a little training wouldnt hurt

Izuku had been dead for a year now, he watched over everyone and was even allowed to see the birth of his two children, and with a call via king kai's back the girl was called eri and the boy Gohan izuku likes food and gohan means rice alright, and its a good name, eri wasn't born with as much saiyan DNA as Gohan was and therefore would manifest a quirk, however Gohan was born with more saiyan than human cells and couldn't manifest a quirk author bs that saiyan cells can cancel out quirk development and stuff, deal with it kids. Even though Izuku was dead and technically didn't need sleep he would sleep anyway in order to keep his body used to it in case he is ever wished back, and right now he was asleep, and someone very important was coming
"HUH?! l-lord whis what are you doing here?" King kai stuttered out at the appearance of the angel whis
"Well, when lord beerus found out there was a saiyan child born with God ki he demanded i watch over him, it is a very rare occurrence you know about 1/10000000000000000000 chances. And he has quite a bit left to show" the voice was powerful and wise and clearly very respected
"More!?! How could this be?" The kai asked the knowledgeable angle
"Im not to sure actually, he was born the second we arrived on planet vegita and immediately drew from our power, his power level rose from an already high 2000 for a saiyan to about 14,000 and it rose slowly without any training at all" he recalled the events "now, to awaken that power" he walked over and looked down at the saiyan before lifting his staff and a blinding green light was emitted, but the result even shocked the angel "i didn't know he had this much" in perspective his power level tripled or about from 270,000,000,000 to 810,000,000,000 in base form, but power levels online aren't really to reliable so hes definitely much stronger now "Hmmm, teach him to tap into super saiyan and bring it to its limits, it will surely benefit him. I must go now, make sure hes extra strong okay" the angel said before leaving the planet
"Looks like we'll have to triple his training" the kai said deep in thought, he was cut of though when Izuku's eyes shot open and he looked around "I-Izuku are you ok?" The kai asked in concern, however he received no reply as the saiyan ran out of the building and to the edge of the planet, he charged some energy allowing himself to go into ssj2 and looked towards empty space
"KA...ME...HA....ME...HAAAAAA" he fired his kamehameha into space and looked at his hands, opening and closing them he looked around himself "what the hell?"he muttered as he turned to the kai "how'd i get so strong all of a sudden?" He asked but the kai only lied to him
"I dont know, thats why i ran to you. You had a massive energy spike" he looked to meet the saiyans determined gaze " Izuku, i want you to try and tap into the deepest part of super saiyan, doing so should let you fully utilise it" and with that said Izuku began to tap into ssj, for 4 months he expelled stamina into the super saiyan transformation and at the end, he got his results. The kai was just watching over earth as per Izuku's request when he realised Izuku's power growing, he was in ssj2 but it was getting larger and larger. He turned to see something that stunned him, the saiyan was letting out cries of almost agony as his hair began to grow out, electricity was flying around everywhere around him, he was breathing heavily, the transformation was so strong it was affecting a dead person
"Huh,huh i did it. I DID IT!" Izuku let out a shout in triumphant, if the kai was to say how much this amplified his normal power he would have to say about 400 times
"WOW, thats crazy strong kid" the kai told him "now that you've gotten this we'll train you to have better stamina, although that might be hard considering we're dead" but as he said that, the transformation cut out and Izuku was reverted to his base form "interesting, so your reverted to base instead of the previous transformation" he looked at the boy with interest
"So im guessing that was super saiyan 3, i can still feel it's affects on me, this is insane" he looked so excited but "theres no body to try it on" he said with the anime tears
"They'll be someone Izuku don't you worry" he said back to the boy. For the next three years Izuku trained, so hard that the kai had to rebuild his little planet about 7 times, the kai had used his power to make it so Izuku would carry on growing, therefore he wasn't 15 on any more, and with 4 years past he was 19 turning 20 soon
Time skip
"I dont have anything more i can teach you now Izuku, its best you go back to earth. Don't worry about keeping trouble away, your strong enough now, id say your the strongest mortal known" the kai told the boy
"Right, ill get Todoroki to use the dragonballs" he went over and placed his hand on the kais back "hey, hey Todoroki can you hear me?" He asked through the kai to receive an echoey reply
"I-Izukuis that you?" The saiyan asked his greatest rival and friend
"Yes its me, i need you to use the dragonballs to revive me, Ive learnt all i can so its best i come back now" he told his friend and when he received no reply he assumed that hed gone to do his task, he waited about an hour before feeling a tingly sensation, looking above his head he saw that his halo had gone. He was alive
"You'll have to run back down snake way Izuku, it will only take the rest of the afternoon with your current speed, there kami will meet you and take you back to earth" the kai said as he looked towards a gate
"Thank you king kai, you've been incredibly kind and helpful. I owe you greatly"he said with a bow
"No need for debt, just carry in protecting the earth and make my job easier ok. Now get going don't you wanna see your friends, i heard that bakugou guy had a kid with some Uraraka girl" he said receiving a giddy chuckle and a breeze as the saiyan took off " i can sense you, majin buu. But you wont win, Izuku will protect this universe, like with frieza and cell" he said as he looked on after the saiyan who was no longer in eye distance, however neither kai no saiyan knew what was happening on earth
