In Dragon Ball: A brutal beating of Frieza at the start

"The pinnacle of the universe? No, this is just my 'pepe'!"
I woke up to find myself transported to the Dragon Ball world, and the first thing I saw was a heavily injured Frieza!
"Ding! Super Saiyan Evolution System activated—Host, please deliver the final blow!"
He intercepted Goku's moment of glory, shattered Frieza with a single punch, and the universe's strongest warriors trembled in shock!
He brutally beat Cell, crushed Broly, and overpowered Jiren, unlocking the ancient Saiyan bloodline and creating the "God's Wrath: Super Saiyan Ultimate" form!
A candidate for God of Destruction? He's just a stepping stone on his path to growth!
The Omni-King Universe War begins! When the geniuses of the twelve universes gather, the protagonist shatters the rules of the arena with a single punch!
however--
A spacetime rift suddenly appears, and the "Supreme Devourer" that devours all worlds descends!
Angels have fallen, the High Priest has bled, and even the Omni-King has fallen silent...
"System, load 'End of the World: God of Saiyans' mode!"
In this battle, I will make the multiverse remember—
Who is the ultimate being who surpasses the Omni-King?
