"Total control ...I could make it jump out of the window, drown itself, throw itself down one of your throats. . ."
-- Fake Moody/Barty Crouch Jr. demonstrating the Imperius Curse on a spider (GF14)
One of the Unforgivable Curses, this spell causes the victim to be completely under the command of the caster, who can make the victim do anything the caster wishes. A victim of this spell is said to have been Imperiused.
References from the canon
- Imperio makes the victim feel as if their minds have been "wiped of all thought" and they are in a "blissful" dream state, as Harry felt when Voldemort put him under the curse several times in the Riddle graveyard. However, he was able to fight against it:
- "I will not, said a stronger voice, in the back of his head, I won't answer. . . .
Just answer no. . . .
I won't do it, I won't say it. ...
Just answer no. . . .
And these words burst from Harry's mouth; they echoed through the graveyard, and the dream state was lifted as suddenly as though cold water had been thrown over him... (GF34)
