While there's something to be said for a sympathetic anime villain, sometimes you just want to see the good guys go up against a truly black-hearted bad guy. Whether it's the joy of watching them finally get what's coming to them or the excitement that comes with seeing what malicious depths they'll sink to next, these characters can be a ton of fun.
The most evil anime villains include villains from shonen hits like Naruto, Bleach, and Dragon Ball Z, but they also appear in shorter series like Banana Fish, Hellsing, and Made In Abyss. While these villains have different motives and are guilty of different crimes, one thing they all share is an utter disregard for the needs and safety of anyone other than themselves, and a willingness to use others to further their nefarious ends?
Which ones do you love to hate the most?
While Shou Tucker is a strong contender for "most evil anime character," in terms of sheer body count, the award has to go to Father. Father is a homunculus who tricked the city of Xerxes into creating the conditions needed for him to acquire godlike powers, wiping out nearly the entire civilization in the process.
Later, he tries to do a similar thing again, this time with the help of his homunculus children, so that he can become a so-called "perfect being." He sees those around him - even his own children - as expendable tools to help him achieve that end, and has no sense of guilt or remorse for any of the lives he's taken.
You thought that this list would feature the infamous villain Dio Brando, and you were right, because here's Dio! This all-powerful vampire begins the series by trying to ruin his adoptive brother's life by doing everything from framing him for crimes to burning his dog alive. As the series progresses, his power, cruelty, and ambition only increase.
One example of his terrible behavior involves promising a woman that he won't eliminate her child, then technically keeping that promise by turning her into a vampire and making her do the deed instead. In fact, Dio is so cruel that one of the only examples of him showing empathy is when he takes his father's life - the reason may have been partially because of how poorly his father treated Dio's mother, rather than solely because of his evil nature. That's not much.
You can't talk about anime villains with hearts of pure coal without talking about Frieza. Frieza is in the business of buying and selling planets, and he couldn't care less about the fates of those planets' inhabitants. In fact, he's the person responsible for blowing up Planet Vegeta, effectively committing genocide against an entire species, for the sole reason that he was worried that their Super Saiyan powers might eventually pose a threat to his power-grabbing schemes.
Never once does he display a shred of remorse for his actions - instead, he gleefully mocks the survivors of his crimes.
Sōsuke Aizen is one of the most notorious villains in the world of anime, and part of that is because of his dark, evil heart. When he first appears, he seems to a be a loyal member of Soul Society, but he soon reveals that he's been plotting to overthrow it for a long time. He uses a combination of murder and manipulation in order to further his plans and ultimately has no loyalty to anything but his own quest for power.
