The Barksian Modulator is an invention of Gyro Gearloose's that can alter a person's voice when swallowed. It is grey in appearance, with a silver panel and red, orange and green lights adorning it.


"The Shadow War!"

When Donald Duck's voice proves incomprehensible to his various allies in the battle against Magica De Spell, Gyro forces him to swallow the modulator. This provides Donald the ability to lead his family and allies in the attack on Magica and her shadow army.
