Voltron is a shape-changing 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). The anime was dubbed and connected together by North American television production and distribution company World Events Productions. The series was not a straight dub, however, as much of the violence of the original Japanese series was removed.
