Theme Song

The Hero (From One Punch Man, English version) (I don't own the song)

One Punch!

3, 2, 1, killshot!

I'm here for fun. I'm number one
(What're you saying!? Frustration! No one can stop me!)
One punch, that's it. I always win
(Listen to me! Victory again!)
Power, get more power
Last minute limit counting 3, 2, 1

Hero! Don't wanna hear you calling out my name
I'm not here for fortune or fame
Hero! Instead, I'll fight knowing nobody knows my name
(Nobody knows who he is!)
My foes are closing in and covering the sky
But I won't turn my back tonight
Hero! I'll stay, until I taste the dirt of defeat someday

Unleash my fist. Hero!

3, 2, 1, fight back!

Press on prepared. Fight fair and square
(What's going on!? All of my foes are gone!)
Let justice last. No questions asked
(Give me the heart to cut through the dark and win!)
Power, get more power. Adrenaline is flowing through my brain!
(Power, get more power.)
With discipline and every hour that I've trained!

Hero! The tallest mountain started as a stone
I once was weak but now I've grown
Hero! I know the weakness within is my greatest foe!
Push on! The mortal man I used to be has died
There's gods inside my fist tonight
Hero! I'll stay until I taste the dirt of defeat someday

Unleash my fist. Hero!

Unbreakable, unyielding, draw the future in my mind
No matter what the cost - at any day or any time!
Hero day and night! Soaring proud and high!

Hero! Don't wanna here you calling out my name
I'm not here for fortune and fame
Hero! Instead, I'll fight knowing nobody knows my name
Push on! The mortal man I used to be has died
There's gods inside my fist tonight
Hero! I'll stay until I taste the dirt of defeat someday

Unleash my fist. Hero!
HERO! (Ah, ah, ah, ah, ah, ah! I'm gonna be the strongest hero!
