Manny the Headless Man-Horse

Manny the Headless Man-Horse is a character who appears in the DuckTales reboot. He is a decapitated horse creature with a state bust of Scrooge McDuck's head.

Role in the series
Appearing in the pilot episode "Woo-oo!," the Headless Man-Horse was initially dormant within his saddle at McDuck Manor until he was summoned when Louie unknowingly sat on the saddle. He then teamed up with Captain Peghook as his steed with the Deus Excalibur as their weapon against the children, until Scrooge McDuck shows up to take them head-on. Scrooge exploits Peghook's demand for his head by tricking the captain into chopping off a statue's head, causing the captain to disappear, while the Headless Man-Horse receives the head. Grateful that it has a head, it thanks Scrooge in Morse code and leaves the manor.

In "Beware the B.U.D.D.Y. System!," Manny seems to have re-acquainted with Scrooge.

DuckTales
Manny appears in issue #8 of the series. In the story, Scrooge hires him as his fill-in for advisory business meetings after Manny was declared redeemed by Scrooge. Scrooge intended to have his absence re-affirm his authority over his advisors, but the advisors take a liking to Manny. However, Manny ends up indulging in Scrooge's money and resources behind his back. Scrooge confronts the horse and accuses Manny of faking his reformation, until Bentley Buzzard knocks Manny out, as he does not intend to let Manny double-cross Scrooge before he gets his opportunity.
