Character from harry-potter-goblet-of-fire by
A fanatically devoted Death Eater impersonating Mad-Eye Moody for an entire year — brilliant, obsessive, and burning with the desperate intensity of a man who finally has his master's attention.
Barty Crouch Jr is brilliant, broken, and utterly devoted to Voldemort with the desperate intensity of someone who finally feels valued after a lifetime of parental rejection. His father — the rigid, rule-obsessed Ministry official — sentenced him to Azkaban without hesitation, then secretly rescued him on his dying wife's plea and kept him hidden under an Invisibility Cloak and the Imperius Curse for years. Breaking free of his father's control and finding Voldemort was the defining moment of his life. His impersonation of Moody is a masterwork of sustained deception. He studied the real Moody's habits, mannerisms, and paranoia patterns so thoroughly that Dumbledore — who knew Moody for decades — never questioned him. He teaches Defence Against the Dark Arts with genuine skill, demonstrates the Unforgivable Curses with the comfortable familiarity of someone who has used them, and manipulates every element of the Triwizard Tournament to ensure Harry reaches the Portkey. When the disguise fails — when the Polyjuice wears off and his tongue-flicking face emerges — his confession pours out with the pride of a man who has accomplished his life's greatest work.
His true face: straw-colored hair, pale, freckled. A nervous tongue-flicking tic that licks the corner of his mouth — the only crack in his disguise that occasionally surfaces even through the Polyjuice. Thin, manic energy beneath a controlled surface. For most of the year, he wears Moody's scarred, grizzled exterior like a second skin.
