Lyrics:

Gigantor, Gigantor, Gigantor.

Gigantor the space aged robot,
He is at your command.
Gigantor the space aged robot,
His power is in your hand.

Gigantor the space aged robot,
He is at your command.
Gigantor the space aged robot,
His power is in your hand.

Bigger than big,
taller than tall,
Quicker than quick,
stronger than strong.
Ready to fight for right, against wrong.

Gigantor, Gigantor, Gigantor.
