Voltron is the name of two composite giant robots and the name of the anime series and comic book series about each of them. He first appeared on screens in the 1980s in Japan in the TV series Hyakujuu-ou Golion and Kikou Kantai Dairugger XV.
The American version merged the two into one: Voltron: Defender of the Universe. In it, the sequence of the episodes was changed and some scenes were cut. There are two almost independent seasons – “Lion Force Voltron” and “Vehicle Team Voltron”, roughly corresponding to the original series.
