The Myhr'an commander commanded the Myhr'an super battle cruiser and was the highest-ranking non-Myhr'an clone Myhr'an in the Myhr'an military. He was an autarch, ruling the Myhr'an as a self-imposed leader. His name could not be pronounced by humans, and his stature, at 2.3 meters, was taller than most Myhr'an.

He helped the M'Tar infiltrate and conquer the Myhr'an as he felt the then-military and then-government were not adequate steps to ensure progress and expansion for the Myhr'an. According to Helena Bourget, his actions -- allowing the M'Tar to slaughter his friends and family and billions of his people for the cause and thus diminishing the Myhr'an to nothing but a puppet race -- and their consequences drove him insane.

In 2372, aboard the Myhr'an super battle cruiser, he accompanied the Myhr'an clones escorting the Myhr'an planet killer. At Canaileus Prime, after a Starfleet away team from the USS Cantabrian shut down the transmission controlling the Myhr'an clones, essentially losing the battle, the Myhr'an commander piloted the Myhr'an super battle cruiser to a hasty retreat.

Later that same year, under the guise of a peace offer, he ordered the super battle cruiser to disable the Cantabrian and kidnap Cantabrian officers Captain Noah Wrightson, Elizabeth Singh, Benjamin Caldwell and Daniel Radke in a last-ditch attempt to appease the M'Tar. Helena Bourget, also aboard the super battle cruiser, freed the quartet, claiming to Radke the M'Tar no longer required the Myhr'an commander's service as he was insane and could no longer control the situation.

With the Cantabrian causing severe damage to the Myhr'an super battle cruiser, the Myhr'an commander attempted to kill Wrightson and Radke. As he attempted to kill the exhausted pair, the Cantabrian beamed them out as the Myhr'an super battle cruiser exploded, killing the Myhr'an commander in the process.
