Conception
One the differences to Prince Lotor in compared to his 1984 counterpart is that he didn't have an obsessive love towards Princess Allura. His affection for her is treated as genuine, which is confirmed by series staff writers. According to the Voltron writer Lauren Montgomery, the reason why Lotor became evil was his tragic upbringing where he was abandoned by his parents, Lotor had to survive on his own, even if it means tricking others to get what he wanted. Montgomery further stated that had Lotor raised by in a better background, Lotor would likely have grown into a much better person. Prince Lotor's life is multiplied by Quintessence, allowing him to live for 10,000 years, due to being already conceived by the time his mother, Honerva, entered the rift on Daibazaal.
Reception
The character has been praised for being a nuanced character.
