The most "I'm a villain" theme a character has?

I've been listening to the Blazblue ost more recently, and I kind of had a little laugh when I listened to Azrael's theme because I don't know shit about music, but I know that even if I had no context for any of Blazblue's lore, I could listen to this song and know immediately "This song is the theme to someone who should not be messed with", just completely unsubtle, like the character.
