Maihar'du was the Hupyrian servant of former Grand Nagus Zek. Maihar'du had taken a vow of silence and was only permitted to speak to the Nagus. He was very imposing and was not only a servant, but a bodyguard and food taster. He was also the flight controller to Zek's personal ship. (DS9: "Rules of Acquisition") He often provided Zek with his favorite drug, Hupyrian beetle snuff. (DS9: "The Nagus")
Maihar'du was played by Tiny Ron.
The only time Maihar'du spoke on screen was as a representation of a Prophet during Quark's visit to the wormhole in "Prophet Motive".
