Sven, a Norwegian pilot, was the original second-in-command. He piloted the Blue Lion and wore a black uniform at the very beginning of the series. In Episode 6, he was badly injured during an attack by Haggar, and was sent away to the planet Ebb to be healed. He was killed in the Japanese version, with his younger brother appearing later in the series. Ebb was attacked and raided by Lotor's Forces and Sven was captured. The prison ship on which he was transferred accidentally crashed on Planet Doom where Sven went into hiding becoming a hermit within the caves. He eventually encountered Allura's cousin from the Planet Pollux, Princess Romelle, who had been sent to the slave mines after she rejected Lotor's advances. During Sven's time on Planet Doom he witnessed Zarkon and Lotor's cruelty to their slaves, which drove him to the point of madness. He recovered thanks to Romelle's emotional support and helped her escape Doom. Sven was later reassigned to the Planet Pollux with Romelle and her brother Prince Bandor. Sven eventually fell in love with Romelle, though he was reluctant to pursue his feelings because he felt he was unworthy of her.
