In addition to being one of the best villain groups, they are also one of the most iconic with their members Jesse, James, and Meowth chasing after the protagonist, Ash, for the majority of the series. While their plans are often foiled and this might give us the impression that the organization as a whole is weak, it is the exact opposite.

Throughout the series, we see them grow from a small group of weak villains to a commendable organization that is able to stand toe-to-toe against powerful heroes. With several tragic yet strong members such as Dabi, Twice, Himiko, and Kurogiri and several Nomus while being led by the twisted minds of Tomura and AFO who are capable of defeating hundreds of heroes in a few moments, the League of Villains was able to stand the test of time while defeating competitors such as the Shie Hassaikai and even merge with the Meta Liberation Army Later which put their forces in the hundreds of thousands.

Despite being created by Father, they all have their own motivations and unique personalities which is what makes them great characters in addition to being an amazing villain organization.

Hunter x Hunter has no shortage of amazing villains, going from the eccentric Hisoka to the powerful Meruem. Even among these, the Phantom Troupe is able to distinguish itself as a group of extremely strong and memorable individuals who commit evil deeds. Despite only being the main antagonists for the relatively short Yorknew City Arc, they were able to win audiences over with their uniquely written characters and creative powers. With their leader, Chrollo Lucifer, there are a total of 13 members in the Phantom Troupe. Since most of the members originate from the same place, Meteor City, they have one of the best dynamics among anime groups despite being villains engaged in murder and thievery. All of the members are some of the strongest Nen Users in the anime who unite and work together equally under Chrollo’s instructions.
1. Akatsuki – Naruto
The greatest and most well-known villain organization in anime is without a doubt the Akatsuki. Formed by Yahiko during the third ninja war, the original goal of the group was to strive towards bringing an end to the violence and working towards world peace. However, through several tragedies, the group took a darker turn where they shifted to a more violent approach through which they would acquire all the tailed beasts and wage war against the world. As the main antagonist group in Naruto which existed outside the system of hidden villages, it was an extremely powerful group with several members who were feared far and wide such as Itachi, Obito, Pain, Orochimaru, and many more. With unique relationships between the members of the groups and the impact they have on the world of Naruto, we believe that they have earned their spot at the top of this list.
