I, Vegetto, Punch the Gods of Destruction and Kick the Omni-King

[System, but not a major focus + invincible + no heroine + original characters]

He unexpectedly transmigrates into Dragon Ball and becomes Vegito, the ultimate show-off. Bound to the Strongest Person Development System, he can keep growing stronger as long as he continues defeating opponents.

In this life, Vegito will shatter his original story’s record of zero defeats. He’ll take down anyone who stands in his way and become the strongest there is.

Vegito: “I’ll restore the glory of the ultimate show-off. It’s my duty!”

Frieza: “If I had another chance, I’d never pick a fight with Vegito.”

Vegeta: “Run! That’s the legendary Super Saiyan! No one can beat him!”

Beerus: “I’m sorry I couldn’t make Lord Vegito use his full strength!”

Super Saiyan 4 Gogeta: “I once thought I was the strongest in all dimensions. But after meeting Vegito, I realized I still have a long way to go.”
