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 (both originally produced by Toei Animation & Bandai, who also produced the popular Super Sentai series in Japan).

Voltron is an announced live-action film based on the Voltron franchise. A script has been written by Justin Marks, but no studio or director have been attached.
