There is no good hero without a good villain. Even Though, the hero is what is known in an anime. However, Villains are a very important part of any anime.
Especially a ‘shounen’ one. The action scenes are what keep the anime alive. Let us review the 5 best anime villains of the anime world.
5. Isabella (The Promised Neverland)

Isabella worked as the caretaker of the Grace Field House. Although initially, she appeared as a loving and affectionate mother, her character was twisted in a lot of ways.
She was a cold-hearted person who was working in the human trafficking business. Bella took a fatal wound from a demon and was not able to recover. Eventually, she died.
4. Esdeath (Akame Ga Kill)

Esdeath was basically the Grim Reaper in a uniform, known as the black cat of the show.
Wherever she went, death would soon follow her in dozens, sometimes even in hundreds. She was definitely ruthless and powerful.
3. Shou Tucker (Fullmetal Alchemist)

Out of all the villains in the entire anime world, this guy was one of the worst. Shou was the most irresponsible and cruel dad.
The fact that he transmuted his own daughter was a cruel deed. Just imagine what kind of headspace one would be in to do what Tucker did.
But most of his deeds can leave you speechless.
2. Nagato (Naruto- Shipudden)

Naruto Shippuden’s Nagato was the villain returning favors for all the pain people put him through. That made him evil.
