Two unrelated anime series were amalgamated to meet U.S. syndication requirements for the 65 episode count. From Wikipedia: "Voltron was an adaptation of several Japanese anime television series from Toei Company. The original television series aired in syndication from September 10, 1984, to November 18, 1985. The first season of Voltron, featuring the "Lion Force Voltron", was adapted from the series Beast King GoLion. The second season, featuring the "Vehicle Team Voltron", was adapted from the unrelated series Armored Fleet Dairugger XV." From Leo AI: "Syndication Constraints: American broadcasters required a sufficient episode count to air a show daily for 13 weeks without repeats. Individual Japanese series often had fewer than 50 episodes, necessitating the stitching together of unrelated content to fill the quota. "
