Verse 1:
I'm the One Punch Man, you can call me Saitama
I pack a punch so strong, it'll give you head trauma
I've fought monsters, villains, and heroes alike
They all fall down with just one strike

I'm the strongest man, don't need a plan
I train hard, that's how I became so grand
100 push-ups, 100 squats, 100 sit-ups a day
Plus a 10-kilometer run, no time for play
I did this for a year, to become the best
Now my punches are like bullets, they pass the test

Chorus:
Overpowered, I'm the one punch man
My strength is unmatched, I've got the upper hand
I'll go for the finisher, Serious (Serious)
No one can stop me, I'm just too fierce
My strength is unmatched, my punches are supreme
Tap you once and you'll see what I mean

Verse 2:
My enemies fear me, they can't withstand
The power of my fist, it's like a command
I take them down with just one hit
No need for a combo, that's just a myth
My training may seem simple, but it's effective
I'm living proof, my strength is reflective
My serious punch is my ace in the hole
It's so strong, it'll make your body fold
My consecutive normal punches, they'll do the trick
They're quick and deadly, you won't even hear a click

Chorus:
Overpowered, I'm the one punch man
My strength is unmatched, I've got the upper hand
I'll go for the finisher, Serious (Serious)
No one can stop me, I'm just too fierce
My strength is unmatched, my punches are supreme
Tap you once and you'll see what I mean

Verse 3:
I've defeated monsters, villains, and beasts
None have been able to stand against me
But I'm getting restless, I need something new
A worthy opponent, who can give me a clue
To what it's like to be truly challenged
To fight tooth and nail, to be unbalanced
I'm looking for that one fight I might lose
To feel the rush of adrenaline, to light the fuse
