Voltron is a giant mecha robot first featured in the 1980s animated television series Voltron: Defender of the Universe. There has since been a second series, made in the 1990s using CGI techniques. The 1980s Voltron series was based on two vaguely-related Japanese anime series GoLion and Dairugger XV (both originally produced by Toei Animation & Bandai, who also produced the popular Super Sentai series in Japan).
