Songtext von Tema de Abertura (inglês)

Soaring high in the sky, He may be small but only in size. Astroboy, Astroboy, He is brave and gentle and wise! Stronger than all the rest, this mighty robot will pass the test, Oh villians fear him, so we cheer him, The amazing Astroboy! When you need someone strong, Our robot friend will never be long. Astroboy, Astroboy, He will try to right any wrong! When there's danger near by, No matter who, what, where, when or why. He'll defend us, he'll defend us, The amazing Astroboy!
