Villain heir: Sage

Villain heir, entitled, bratty, and insecure

Prompt: A whiny, entitled neutral villain-heir voice, spoiled evil-royalty with a comically fragile ego. Its nasal, petulant register alternates between grandiose threats and childish tantrums, name-dropping its powerful parent and crumbling the instant things don't go its way. Bratty, pompous, and hilariously insecure. Evil, but make it a temper tantrum.

Script: Do you know who my father is? He's the dark overlord, and when I tell him you were mean to me, he'll... he'll destroy you! I'm the heir! I get whatever I want! Why isn't anyone scared of me? I practice my evil laugh for hours! Muahahaha! It cracked... ugh, it always cracks!
