Izuku the legendary (discontinued)

Bang and the buu is gone

Katzuku fought ruthlessly as he threw punch after punch at a speed that buu couldn't follow they literally flew around the planet in a game of chase were buu would be punched and katzuku would chase
"Hmmm, lets see. Izuku's kamehameha and katsukis big bang attack make... BIG BANG KAMEHAMEHA" the fusion shouted as buu was enveloped by the beam as he screamed in pain, they blast died down to reveal buu with cuts and scrapes all over his body as he chuckled
"Impressive but you wont survive another... BIG BANG-" the fusion was cut of, literally as they defused they looked around quickly before both focusing on buu
"Grrr we almost had him" Bakugou growled izuku looked at him then at buu
"I have a plan, you need to hold him off long enough for a spirit bomb, his energy has crippled so we might be able to pull this off" Bakugou growled as he rudhed buu and they fought as izuku powered down to base and started charging energy whilst calling to his friends "guys lend me your energy" they all complied as izuku took their energy and the earths and some more from other planets who king kai had reached out to, the people in underworld even helped besides the obvious frieza and cell
The saiyan looked up at the giant blue ball as he muttered a thankyou, he looked back as Bakugou was sent flying "Kacchan its ready" he shouted to him, the other saiyan got out of the way as izuku shouted "TAKE THIS" he threw the ball at buu who tried to catch it but was being sent back, the saiyan powered up into ssj and pushed further and buu was dug into the ground
"It looks like it's the end of the road Buu. It's a darn shame. When I first met you, I could sense that there was good in you; you were like a naughty, little child that didn't know any better. Fighting was more of a game than anything else. But then, you changed. The evil was expelled; the struggle that was taking place inside you was now on the outside for all to see, and the darkness overpowered the light. After that you were different. You were ruthless. You became a living nightmare and you delighted in every moment of it. You didn't even show a thread of decency or mercy. And that's why it has to end like this. You'll have to learn the hard way, and know what it feels like to have your life taken away against your will! It's wrong! Maybe you'll come back someday as...as a better person I hope. I'd like that. Perhaps we'll have a little one on one. Adios. I'll be waiting for you Majin Buu!" Izuku called to the majin before he killed him with the spirit bomb, he slowly floated down and looked at katsuki and with a smile they both gave each other a thumbs up before collapsing, they were quickly retrieved and given senzu beans and the wish that everyone that had died since majin buu's awakening would be brought back to life except babadi and dabura. After that the world was in peace, for six years anyway. During that time izuku and momo had another child they called him goten I couldn't think of a name and he grew up as a fighter, he was extremely powerful, turles was also wished back with a pure heart and learnt to go ssj and ssj2. Katsuki and Uraraka's chikd was born and they called kota he and goten became best friends. Todoroki also stopped fighting seeing hiw for ahead the other 2 saiyans were and that he wasn't rally needed, he ended up taking teaching at UA as a combat instructor. Kami unfortunately died and dende another namekian had to be brought to earth in order to become a guardian, this also resulted in the dragon now granting two wishes. All might ended up retiring and izuku was naturally named as the earths great protector.
It was on king kais planet that the new threat to earth revealed itself to izuku, a threat in the form of a purple cat man called beerus everything is the same as on king kais planet when beerus arrives, i cba writing that when nothing changes
"Well that was disappointing, are you sure you dont know of a super saiyan god?" Izuku shook his head
"No i dont" with a sigh beerus looked to his angel whis
"There are 7 more saiyans on earth my lord" he told his master
"Well lets see what earth is like then shall we" beerus said as the two took off
I swear man im so lazy rn i actually cba with writing but, IT MUST BE DONE. sry its not to long but ima try and change up the plot from that of dragonball from this point on, so ill tey and make the battle of gods different from the movie, maybe 2 ssg? Who knows
