Lotor

Lotor was born as the only son of Galra Emperor Zarkon and his wife, the then Altean Alchemist Empress Honerva. When Lotor was conceieved, his parents rejoiced that the empire would have an heir. While Honerva was still in her early pregnancy stage, she and her husband decided on names with Zarkon suggesting "Koltor", the name of a Galra conqueror though Honerva wished to name her son "Lotarius" after an Altean explorer, struggling to choose which name to decide on, the two combined their choices and named their son, Lotor.

After years of being exposed to a major amount of Quintessence, Honerva fell gravely ill and in a final attempt to save their son's life, Honerva and Zarkon entered the Rift which seemingly killed them. After some time, the two returned though corrupted by the Quintessence. Despite his parents now corrupted, Lotor was born in good shape and healthy, though Honerva, now amnesic, refused to acknowledge her son as her own kin and Zarkon coldly commanded the doctor to take his crying, infant son away.

Once Lotor became slightly older, a Galra named Dayak assumed the role of Governess for many of Lotor's young years. As his sessions with the Governess went on, Lotor would be presented to his father for progress updates, during which, the young Galra would ask Zarkon where his mother was, still cold and distance, Zarkon would always tell his son that his mother was gone. Eventually, Lotor began forming a bond with Kova, a cat that once belonged to his mother.

Then old enough to act as a Galra commander, Lotor was given a mission which involved him taking over a planet to harvest its Quintessence. Unlike his father, Lotor believed that working alongside its inhabitants would be much healthier and efficient for both sides, after Zarkon and Haggar arrived to foresee the progress, Zarkon became furious at the idea of his son wanting to ally himself with another species, Honerva, now known by Haggar, stunned the young prince and after waking up, Lotor watched as the planet had already been destroyed and drained with no survivors, furious by what he saw, Lotor yelled at Zarkon and as a result, his father banished him from the Galra Empire.

After being banished, Lotor went around the universe and eventually met four hybrids who had Galran blood in them, Acxa, Zethrid, Ezor and Narti, who was blind, during his exile, Lotor and his new generals, started an Altean Colony which seemingly acted as a safe haven for Alteans.

After his father was critically injured by Voltron, Lotor was brought back to the empire to assume his role as heir to the throne. To prove he was worthy of taking over, Lotor was ordered to fight within a ring in front of an audience where Lotor challenged Throk, a Galra who looked down on Lotor for how he fought, despite winning his fight and having the opportunity to kill Throk, Lotor spared him and instead offered his opponent a chance to stand beside him whilst making a speech to his citizens on how backstabbing got their race nowhere and because of that, he himself would change it. After walking away from the fight, Lotor, now out of earshot of Throk, commanded his generals to leave the opponent on a desserted planet after they asked him what to do about him.
