Hogwarts: Full level unforgivable spell at the beginning

Dylan: "Voldemort, I just mastered the highest level of Unforgivable Curses. Please believe me, I am really a good kid. Just look at what I did in school!" Professor McGonagall: "You mean the one where you defeated an entire gathering of Death Eaters with a hundred dementors a second, and the one where you were able to hang out with a bunch of Dementors and control them at will?" Dylan: "No, I mean, there's not a single book in the library that I haven't read! I have full marks in all my courses, including magic! Even Voldemort was defeated by me using the Unforgivable Curses." Professor McGonagall: "Yes, that's right. That group of cultists even want to nominate you as the new Dark Lord!" Dylan: "Oh my god, professor, isn't this easy to solve? I can kill all these Death Eaters with an Avatar, and no one will want me to be the Dark Lord!"
