Sincline

Sincline reprimands an officer by cutting him in two.

Sincline is the Golion counterpart of Lotor.

In comparison to his Voltron counterpart, Sincline is more murderous and unhinged, killing his own soldiers and servants for the slightest pratfall or imagined slight. Sincline seems to derive pleasure from death as he often grins or chuckles after he kills someone.

Behind Sincline's Princely facade lies a lecherous brute.

Sincline's obsession with Fala is explained because she resembles his mother, whom Emperor Daibazaal (the counterpart of King Zarkon in Voltron) had killed after Sincline was born because she begged him to spare the lives of civillians who had already surrendered.

Sincline was unaware of his mother due to Daibazaal and Honerva refusing to tell him about anything about her other then that she died during his birth, despite this he sometimes has dreams and images of her visage. In the second last episode, Honerva reveals the truth that his mother was from Altea, making Sincline Half Altean, he goes more insane and violently kills her.

He dies by the hand of Shou Shirogane in the finale of Beast King GoLion as a way to avenge his brother Takeshi in a suicidal tactic.

Trivia

• His age is given as 108 years in the 28th episode. This is either because of Galrans having a longer lifespan or Sincline extending his life with the flowers of Planet Amazon like his father is said to do.
  • Honerva seems to contradict this in "Golion's Desperate Battle" , as she claims that Daibazaal fathered Sincline on an Altean girl during the occupation of Altea, which would make him 16 at most (Galra's occupation of Altea started in 1984).
