Prince Imperial Sincline is the secondary antagonist of the anime series Beast King GoLion. He is the crown prince of Galra and a half-Altean. He is known as Prince Lotor in the English dub/re-edit, Voltron: Defender of the Universe. A dangerous and cunning adversary, his only weakness is the fact that he fell in love with Princess Fala (Allura), who somewhat resembles his mother whom his father, Emperor Daibazaal (Zarkon), killed after begging a favor to pardon the other prisoners but was refused. He plots to overthrow his own father and marry Princess Fala.
