Samuel Holt is a character featured in Voltron: Legendary Defender and the father of Matt and Katie Holt who went missing after being taken prisoner by the Galra Empire during the Galaxy Garrison's expedition to Kerberos.
Sam Holt was a scientist with Galaxy Garrison, who along with his son Matt embarked on a mission to Kerberos with Shiro serving as their pilot. He left his daughter Katie and his wife behind on Earth, only to be captured by a ship from the Galra Empire and sent to a work camp due to being unfit for gladiatorial combat. The disappearance of the Kerberos crew was publicly deemed an accident by Galaxy Garrison, but Katie refused to accept this and infiltrated the organization under the false identity of Pidge Gunderson to learn the truth. Sam and Matt were held for a time aboard Sendak's ship but were later moved to an unknown location; Pidge became determined to find them after becoming a Paladin of Voltron.
