Zandu is a Drule pilot who is captured by the S.S. Explorer crew. Commander Hawkins, in usual form, treats the pilot as a guest instead of a prisoner. However, this upsets Shannon, a member of the Voltron Force Sea Team, who has a brother being held prisoner by the Drules. Shannon, upon getting to know Zandu, realizes that Zandu, despite being on the side of the enemy, is only following orders and unaware of the evil nature of his masters. Zandu is allowed to return to his ship, but is shot down by a Drule commander, who believes it is a trick by the Humans.
- In the American version of Voltron, Zandu crash-lands on a planet and though badly wounded, apparently survives. As is the usual case, he dies in the original Japanese version.
