Warlord Ranveig is a ruthless Galra Commander in season five of Voltron: Legendary Defender. Thanks to his awfulness, Zarkon sent him to the dangerous areas of the universe. Several groupings swore loyalty to him. And when Lotor killed Zarkon, he tried to plow his own power in Kral Zera. But when Haggar's puppet Commander Sendak fought against him, Sendak beat him out.
