About Empress Undergu
She is mentioned on the page of the jerkwad Skearhead:
Skearhead is a cold and threatening being who is hard to read. On the outside, he appears to be a loyal servant of Empress Undergu. However, on the inside, he is actually manipulative and heartless. He is willing to use his inferiors for his and the Empress' benefit. He only prefers completing his goals and only confronts in battle if the other party attacks him first. He thinks that power is everything, the key to winning, and should be used to destroy everything, and those without it are worthless. Skearhead will do whatever it takes to complete the goals of the Undergu Empire, including turning Minoton into a Ranborg against his will, trying to kill Battamonda for turning good, and abandoning his mission. Despite his cruelty, Skearhead cares for Empress Undergu. He served her father, Emperor Undergu, loyally and became her caretaker after his demise. However, Skearhead is cruel and aims to ensure that Undergu Energy reigns supreme. He backstabbed and killed Emperor Undergu, whom he influenced into battling the Kingdom of Sky Land, and then killed when he made peace with them. He even brainwashed Empress Undergu into believing that Princess Elleelain killed her father to ensure she resumed the fight.
