Man-At-Arms is the primary title of Duncan, a fictional character in the Masters of the Universe franchise. He is a supporting character in both the Filmation and MYP versions of He-Man and the Masters of the Universe.
In the 1980s animated series
, Duncan is an inventor, soldier and Teela
's foster father, as well as mentor to Prince Adam
. The Sorceress of Castle Grayskull
asked Man-At-Arms to adopt Teela
because she felt that she could not raise her daughter and protect Castle Grayskull
at the same time, begging: "Please, take care of my daughter. She is all I have left." Man-At-Arms complied: "She will always be safe with me for as long as I live."
Man-At-Arms wears armor which is slightly different from that of the standard uniform of the royal guards. His mustache was not present on the original figure (which was also beefier and more menacing), having been added by Filmation to make him look older, wiser and more fatherly. Man-At-Arms has an understanding, fatherlike voice. He is often pestered by court jester Orko, as Orko's magic tricks often backfire directly at him. Duncan is also one of the three people who know He-Man's secret identity, as explained in the introductory sequence of the original cartoon.
The 2002 cartoon
portrays Duncan as a much more serious and darker character, with more of a connection to the Sorceress than was previously shown. As in the Filmation series, Man-At-Arms is Teela's adoptive father, but he is also depicted as an officer with the definite rank of General instead of the undefined, but still high-echelon
position he holds in the Filmation cartoon. Likewise, Man-At-Arms has a close mentor/student relationship with Adam in addition to aiding He-Man and leading the Masters. It is also revealed that he is the brother of Fisto
. In this series, Man-At-Arms was voiced by Gary Chalk, who also voiced He-Man in The New Adventures of He-Man
