Commander Ladnok is Galra Commander in season fourth of Voltron: Legendary Defender. She transported Haggar to Naxzela, but when Haggar tried to destroy the planet and Lotor blocked it, Haggar ordered her to take her and the troops out.
In Blood Duel, she informs Haggar that Zarkon is at a prisoner exchange to retrieve Lotor.
Following Lotor's ascension as emperor, Ladnok does not submit to Lotor and battles Trugg for control of Warlord Ranveig's base, which houses a secret superweapon. Trugg's forces were able to touch down on the planet's surface and infiltrate the base, leaving Ladnok's fate unknown.
