Commander Samuel Holt is an officer of the Galaxy Garrison and the father of Pidge who went missing after being taken prisoner by the Unnamed Galra Commander of the Galra Empire during the Galaxy Garrison's expedition to Kerberos. Pidge has been searching for him and her brother Matt ever since.

After being captured, he was separated from his crew and sent to a work camp with prisoners deemed too weak to fight. His scientific expertise granted him placement in a prison overseen by Lotor, who reveals his location to Team Voltron. Samuel is taken by Acxa, Zethrid, and Ezor before his children can retrieve him and is used by Zarkon in an attempt to capture Lotor and the Voltron Lions. The attempt fails, and Samuel is rescued and returns to Earth.


Sam Holt is a middle-aged man of modest build. He has somewhat thin eyebrows, a notably long jawline, and keeps his hair cropped short. Prior to his capture, he was clean shaven and kept an almost immaculately clean cut appearance.

During his imprisonment by the Galra Empire, his hair grew out long as well as developing a notably large beard as well.

Following his rescue by Team Voltron, Sam once more trimmed his hair, but kept his beard, albeit groomed and closely cut.


Overall, Same can be seen as a jovial, well-meaning explorer - the consummate science nerd with an endless thirst for knowledge and adventure. An exceptionally kind man, Sam is known to be very close with his crew mates, as he described them to his daughter as being like family.
