Name or share a pic example of what makes Russia so damn freaking scary (I already hav several thoughts in mind O-O)

U know what is tripping me out lately? Well, after reading a *AHEM!* something on Fanfiction based on Russian, I just can't stop fantasizing about him T-T It's creeping me out a bit too. For some reason, I'm attracted to his violent behavior. Badboy fetish? I really don't know o__o
So describe what scares you about Ivan and, as a bonus (If ur a Russia Fan)describe what u LOVE/ADORE about him.
