So...what do you think is the creepiest personally i find Belarus from hetalia f*cking creepy
I took this off the wiki

Russia is Belarus' older brother. Her love for him is obsessive and unrequited, though much to Russia's dismay. While Belarus wishes to marry Russia, he sees her as a younger siblings. She is shown to stalk after him, as well as stick by his side to intimidate others. It is also hinted in her and Ukraine's character song Carrots and Sticks that her sadism may even extend to her brother, as long as it keeps him with her. The Hetalia "desktop buddies" elaborated on Belarus' obsession for Russia further, with her stating her desire to get suggestive photos of her brother.
And
Though Lithuania has a crush on her, Belarus despises him and treats him harshly. When they were children, she broke his leg and strangled him. When Lithuania finally managed to arrange a date between the two, Belarus broke all of his fingers. It is implied that Belarus' hatred for him comes from the Lithuanian annexation of Belarus during the Grand Duchy of Lithuania era. Due to the annexation, Belarus was separated from Russia for a long time period. In the Halloween 2011 event, Belarus does not treat him with her usual cruelty. ok maybe that's just mean not creepy but still also she looks like a sweet little girl with a bloody knife thats already unnerving

Kyubey from Madoka Magica creeps me out to this day.  His expressionless face, innocent sounding voice, and complete lack of emotion(mainly empathy) mixed with the appearance of an adorable fictional animal franchise mascot just make me very uneasy.
