Initially produced as a joint venture between World Events Productions and Toei Animation, the original television series aired in syndication from September 10, 1984 to November 18, 1985 as "Voltron: Defender of the Universe".
Voltron is one of the best known and popular Super Robots around the world and many versions of the characters have been produced all around the globe.
The Lion Voltron robot toy was also widely released as Lionbot which was essentially a Hong Kong produced bootleg version of the toy, identical to the Godaikin version.
Toynami is the current license-holder and Trendmasters had the license in the mid-to-late '90s.
