This thread strongly focuses on Pure Evil Villains who are surprisingly attractive, even if looks can kill at often times. And yet, we just appreciate them solely based on both their appearances alone.
Now, I must also note that we all have our opinions regarding these types of villains and the Dark Ones (or admins/moderators) can enforce this if things were to get out of hand. And yes, there's also non-PE villains to appreciate, but this blog is strongly focused on the Pure Evil ones as they stand out from other, regular villains.
Galia (from Parallel Paradise): Even from all the reprehensible actions she committed, you can't help but just gander at her amazing looks, especially with her innocent (yet facade) nature in her jester costume. Furthermore, she is a prime example of a femme fatale yet still be quite an attractive woman, assuming she doesn't shift into her monstrous form, or as a bloodthirsty witch. If looks could kill, at least there won't be any regrets afterwards.
Herrscher of the Void (from Honkai Impact 3rd): A perfect example of a villain whose crimes are so atrocious and is yet widely popular based on her killer yet beautiful looks, especially if she's gotten a huge praise by others in the Honkai Impact 3rd franchise despite her massive body count to show. Hate her or love her, she's basically a deadly yet wonderful sight to behold.
Dio Brando (from JoJo's Bizarre Adventure): To me, he's essentially a chick magnet beyond his long list of crimes, especially with those jacked-up muscles to go for that makes regular bodybuilders jealous. And he is also equally famous for his quote "ZA WARUDO!", especially in terms of memes (JoJo's Bizarre Adventure is famous for their variety of memes, not just Dio). All in all, he's quite the looker, even if he's out for blood.
There you have it. Sometimes, even Pure Evil villains can be quite attractive amid atrocities committed by them. Do you have any Pure Evil villains from various franchises you find surprisingly attractive?
