Opening Credits (English)

There you go, Astro Boy,
On your flight into space
Rocket high, through the sky
For adventures soon you will face!

Astro Boy bombs away,
On your mission today,
Here’s the countdown,
And the blastoff,
Everything is go Astro Boy!

Astro Boy, as you fly,
Strange new worlds you will spy,
Atom celled, jet propelled,
Fighting monsters high in the sky!

Astro Boy, there you go,
Will you find friend or foe?
Cosmic Ranger, laugh at danger,
Everything is go Astro Boy!

Crowds will cheer you, you’re a hero,
As you go, go, go Astro Boy!

Soaring high in the sky,
He may be small but only in size.
Astro Boy, Astro Boy,
He is brave and gentle and wise!

Stronger than all the rest,
This mighty robot will pass the test,
Oh villains fear him, so we cheer him,
The amazing Astro Boy!

When you need someone strong,
Our robot friend he’s there before long.
Astro Boy, Astro Boy,
He will try to right any wrong!

When there’s danger nearby,
No matter who, what, where, when, or why.
He will defend us, he’ll defend us,
The amazing Astro Boy!
