Summary

The medium of anime has brought with it everything fromwholesome slice-of-life showsto horrifying stories that will give viewers nightmares. However, the first thing many people think of when it comes to anime is bombastic action and clear morals, with heroes and villains fighting against each other in a bid to either save or destroy the world.

As a result, several hugeanime villain groupsare formed to torment the world throughout several anime, with many of them becoming iconic aspects of pop culture. Whenever a member of this group appears in their respective series, viewers can rest assured thatsomething serious is about to go down.

CERN in Steins;Gate

Updated Jul 23, 2025, by Huzaifa Haq:The most important thing in any story is conflict. The better the central conflict, the easier it is for the viewers to stay hooked to a show. The two parts of the conflict are the heroes and the villains. Heroes are good for viewers to relate to, but if the villain they’re facing isn’t compelling as well, they won’t be as engrossed in the story. The greatest story writers understand this concept and spend as much time crafting the perfect villain as they do making the hero, the world, and the plot. If the hero gets a band of helpers, why can’t villains team up as well? The more, the merrier, after all.

SERN is the main antagonistic organization that is found in theSteins;Gateuniverse. Based on a real company, CERN, the members of SERN take a more heavy-handed approach to science, attempting to eliminate and ruin the lives of the main characters throughout the show.

The most sinister part of this organization is the fact that they don’t let go, no matter what the main character tries.No amount of dimension hopping and time travelsaves him from the clutches of this faceless organization, and they always manage to find him in the end.

Traditionally, pirates are seen as the bad guys, andthe marines who go against these piratesare meant to be the good guys who uphold the law for the sake of the citizens. But the roles are somewhat reversed inOne Piece.

Lunarians in Land of the Lustrous

The marines, an organization created for world peace, fight against any and all pirates and create an authoritarian rule within Oda’s creation. Their heavy-handed tactics, corruption, and anti-freedom cause make them an easy enemy to root against when following the protagonists.

Land of the Lustrousis an anime built on mystery. It thrives on making the viewer question the nature of the world they’re watching, and the Lunarians are a perfect example of that.

Umbra Hands in Made in Abyss

These other-worldly creatures appear with a chime, attack, and attempt to kidnap the main characters, and leave just as mysteriously as they first come. Their alien features,indiscernible reasoning, and horrifying competencemake them absolutely terrifying.

Umbra Hands is an organization that shows up at the end of the first season ofMade in Abyssand represents the first big hurdle that the main character has to cross to get closer to her goal. The existence of this organization, the cause they were created for, and the method of their creation, all lend themselves to creating perhaps the most creepy organization in all of anime.

The Red Dragon Crime Syndicate from Cowboy Bebop

The charismatic leader of the group is incredibly powerful and is a major hurdle for the main character. Even after the main character goes past him,the consequence of crossing him remains with herthroughout her journey.

Spike was once an assassin with the Red Dragon Crime Syndicate along with Vicious and Julia, and the trio became friends during their action-packed adventures together. Julia was with Vicious at the time, but she and Spike developed feelings for each other before choosing to run away from this crime syndicate. The consequence of such an act was that they would be hounded by this ruthless underworldanime villain groupfor the rest of their lives.

During their escape, Spike assumes that Julia lost her life, and Vicious becomes his sworn nemesis. The duo clashes time and time again during the course of the series. The bombastic finale sees Vicious assume control of the Red Dragon Crime Syndicate, and Spike single-handedly takes on this criminal group before killing his nemesis. The injuries he incurred were severe, and he lost his life soon after.

It’s easy to laugh off the Frieza Force’s threat given the galaxy-level threats that Goku, Vegeta, and the rest of the Z Warriors have faced since their legendary adventure in Namek. However, doing so would be a huge disservice to one of the most tyrannical anime villain groups inDragon Ball Z.The Frieza Force conquered planets and oppressed them with their might for centuries.

The Frieza Force makes a return inDragon Ball Superand is just as intimidating as most people would assume. Gohan suffered the brunt of the revived emperor’s wrath before Goku and Vegeta appeared to save the day. The Z Warriors are augmented by the might of a new Super Saiyan transformation andmake quick work of Frieza, who fails to emerge victorious even after unlocking a new transformation.

Borutomay seem like an unnecessary way to continueNaruto’s narrative despite the latter ending on a satisfactory note. However, hardcore fans of the series who suffered through a slow and meandering start are being rewarded with some of the best battles and transformations in the series. A huge reason whyBorutohas become compelling is because of the introduction of Kara, an anime villain group with dastardly motivations to gather a ton of power by any means possible and attain godhood.

Aogiri Tree Members in Tokyo Ghoul

Unlike Akatsuki, Kara seems more cerebral in nature. They take both might and wits into consideration when admitting members into their group. However, the Inners are known for boasting supreme might as combatants and must not be underestimated by anyone seeking to hunt down and infiltrate this group, even if only one of these Inners has survived in the form of Code.

Ghouls can be monstrous if they don’t control their eating habits, but even the ravenous ones of the lot know to stay in the shadows and not draw unnecessary attention. However, Aogiri Tree scoffed at this notion, believing that ghouls were the dominant species and that regular humans should be culled for society to evolve.

The Powerful Forces of the Monster Association in One Punch Man

Suffice it to say, this organization inTokyo Ghoulwasfull of heinous individualsbeing directed by the One-Eyed King to cause untold death and destruction. If the CCG wasn’t there to save the day, then there’s no telling what would’ve happened if no one stood in Aogiri Tree’s way as the group turned their twisted goals into a grim reality.

It’s easy to ignore the threat of most monsters inOne-Punch Mangiven just how comically powerful Saitama is, but the series has done a great job of showing time and time again that regular heroes can find it pretty hard to take on monsters that trigger a Dragon or even God threat level, with S-Class heroes finding it challenging to take these monstrosities on.

The League of Villains in My Hero Academia

The Monster Association wasfull of powerful villainswho wreaked havoc and caused more to join their cause in the process. If it hadn’t been for Saitama’s overwhelming strength, no one could’ve survived the onslaught of a fully-powered and terrifying Monster Association.

My Hero Academiacontinues to be one of the mostpopular shonen animearound that fans can check out, with the series starting on a pretty high note when Quirkless Midoriya became the new inheritor of One for All. However, Japan has to weather the assault of several villains, with a heinous group known as the League of Villains forming early on.

Their attempts to convert Bakugo to their cause may have been unsuccessful, but this was just a taste of the power they wished to wield. In no time, they expanded their reach and numbers, turning into the Paranormal Liberation Front. The recent version of this group may be more threatening on a national scale, but there’s no denying the sheer dread that fans experienced whenever the smaller and intimate League of Villains took center stage and made their plans a reality.
