Looks can be deceiving because while you stare at Lucy’s naked body, you’ll probably be sliced in many tiny pieces because Lucy is one dangerous gal.

Lucy is a Diclonius, a new type of human species with psychokinetic abilities evolved through a genetic mutation. Due to their new abilities and, well, people do fear the powerful and unknown, they are at odds with the humans to the point that the Diclonius may eventually replace humans as the dominant species on Earth. There are countless experiments to replicate or control the Diclonius, but Lucy is, in fact, a naturally born Diclonius and scientists call her the queen of her species.

Unfortunately for the human race, Lucy is extremely violent and will kill any human on sight using her “invisible arms” called vectors. Vectors are extremely powerful that can destroy anything it touches and since they’re invisible and telekinetic in nature, they’re hard to dodge or even hold. Many fell victim to Lucy’s vectors and throughout the anime, she has killed almost a hundred people… in the most brutal way possible.

Normally vectors have an extremely limited range around a couple of meters, but the potency and range increase over time from 2 meters, to 5 meters, to long enough to engulf the entire world and has enough destructive force to crush the planet. Ouch. So with those overpowered vectors of hers, why is Lucy at number 10? Unfortunately, the anime adaptation toned her power down with a range of a few meters and kill count to less than a hundred. In the manga, you can’t escape her vectors and unlike the anime, Lucy has murdered thousands of people.

Nanoha is your typical grade school girl who happens to have extremely high magical power and ended up being one of the most stupidly powerful characters in the Nanoha universe. While you can argue that every main character is meant to be powerful, Nanoha takes a few steps higher because her character design and powers took inspirations from the popular mecha series Gundam.

The Nanoha series overall took inspirations not just from Gundam, but from various mecha anime from the 70s to the present. Nanoha, in particular, is inspired by the Gundam’s main protagonists Amuro Ray and Kira Yamato, both sharing the same color palette. Nanoha’s powers are also inspired by the Gundams of Amuro and Kira, as these mechs are considered one of the most powerful in their respective series.

If a character is inspired by skilled mech pilots and their powers are inspired by overpowered robots, it’s natural for the character to have the OP qualities as well. Plus, Nanoha has a tendency to shoot first, befriend later. So if you wanna be friends with Nanoha, expect a huge crater behind you.

Espers are special humans who emit AIM, also known as An Involuntary Movement, a phenomenon… that’s basically magic. AIM is just a silly acronym of magic. *ahem* Espers are special humans with the ability to use magic and espers are ranked into levels with level 5 being the most powerful. Misaka Mikoto is one of the 7 most powerful espers in Academy City and her power is electromagnetism.

Nicknamed Bug Zapper by Kamijou Touma, Mikoto is a living power generator with a staggering 1 billion voltage output. Imagine the free energy she can give to Academy City if she sticks her finger in a power socket for one week.

Mikoto is an Electromaster who can pretty much do anything with electricity and magnetism to the point of absurdity. She can shoot lightning bolts from her forehead (throwing bolts with your hands is so ancient mythology), incapacitate enemies by targeting organs with electricity, disrupt electronics, even hack them by altering the signal of the circuits, manipulate metal around her like turning them into shields, being able to stick to metallic walls, has telepathic immunity, spatial awareness… man, the list goes on. Oh, and she can fly because of science!

With a huge laundry list of powers, there is one move that trumps all — Mikoto’s signature move, the Railgun. Mikoto shoots metal projectiles at very high velocity by channeling her power through her arms and to the projectile of her choosing (mostly arcade tokens). The Railgun is so powerful it can destroy everything it hits, which is impressive considering the size of the projectiles used.

Claymore is a name coined by humans to describe pale female warriors who wield great swords called claymores and hunts demons that feast of human flesh called the Yoma. These demons are extremely powerful and only the Claymores, enhanced with Yoma blood, can defeat them.

The main protagonist of the series is Clare, a claymore who rose through the ranks through sheer will and determination. She started out very weak with ¼ Yoma blood compared to the other warriors with ½ Yoma blood, but after a series of events, countless battles, she quickly gained power and eventually she is powerful enough to stand toe-to-toe with Phantom Miria, a powerful claymore with inhuman speed and agility who defeated an entire generation of claymores (with a few exceptions).

Clare’s powers include enhanced speed, strength, agility, healing power, and is a master of a few powerful sword techniques like the Quicksword - channeling yoki energy to the arm and making it go berserk with a barrage of high-velocity swings, and the Windcutter - similar to the Quicksword but the slashes are more precise and normally doesn’t require yoki energy to use.

But Clare’s most powerful and the most dangerous move to use is her Awakened Limbs. By channeling yoki energy to her limbs, she can force transform her limbs into that of a yoma to deliver destructive blows at lightning speed.

Ryuuko is essentially a hot-blooded male hero in shounen anime with a skirt… and female features. What that implies is Ryuuko has the same perks like her overpowered male counterparts. Hot-blooded? Check! Reckless, but a resilient fighter? Check! Grows stronger as the series progresses? Check! Has a dark side, or hidden powerful trump card that no one predicted? Check! However, Ryuuko still stood out among her counterparts thanks to her character and assortment of powers.

Throughout the series, Ryuuko constantly fights the students of Honnouji Academy who wears special Life Fiber-infused uniforms called the Goku Uniforms. Life Fibers, depending on how much is sewn into the uniform, gives its wearer superhuman speed, agility, power, and give unique special moves depending on how they are custom-made. A three-star goku uniform, composed of 30% life fibers, can easily shake the foundations of the school and it can even obliterate it.

Thankfully, Ryuuko gets help with a lot of allies, but what makes her formidable against her enemies is, SPOILER ALERT, she's completely made of pure life fibers, making her one hell of a powerhouse.

Eucliwood, or Eu, looks like a goth loli who rarely speaks and while it may look silly for a necromancer to fully clad in armor, Eu intentionally burdens herself because she possess the power to alter fate just by saying it. Her magic is so powerful, Eu is even afraid of it, and after a lot of hardships, she left the Underworld, decided to go mute, and wears a special armor that suppresses her fate-altering power.

What makes her so powerful? Well, she can kill anyone just by saying “Die.” You could say Eu is part raiser of the dead and part Death Note. The only difference is Eu doesn’t need to figure out and write down the names of her victims.

Explaining Saber’s convoluted story, character relationships and power is going to be tough because everything about Fate/stay night is as confusing as the theory that the universe came into existence out of nothing. If you’re planning to delve deep into this lore-rich series, be prepared.

Saber is a Servant, and a servant is a heroic spirit or divine spirit summoned to fight along with their masters for the Holy Grail. Her powers vary from master to master (mana capacity, personality, etc.), so her powers are hard to scale.

Saber is very skilled with a sword, but her true strength is her enormous amount of magical power. With her magical power, Saber is extremely durable because she can repair her armor and coupled with healing ability, she can absorb a ton of damage. With an assortment of special moves like making her sword invisible to confuse her enemies, her most devastating move is perhaps her ability to call forth the last wishes of fallen warriors across time, focusing that energy into Excalibur to unleash a wave of energy that can destroy almost anything. And together with Avalon, a scabbard that gives her absolute defense, Saber was able to defeat Gilgamesh, the most powerful servant in the Fate universe.

Another character with fate-altering powers, Beatrice is one of the most, if not, the most powerful witch in the Umineko universe. Unlike Eu, who fears her powers and suppresses it, Beatrice carelessly uses her powers of life and death just to torment everyone and entertain herself. And what a way for her to entertain herself.

Beatrice can kill anyone and revive them at will but she isn’t the type who enjoys mindless bloodlust (well, most of the time). She uses her power to challenge Battler Ushiromiya, Beatrice’s formidable enemy, to solve a series of murders that’s happening on the isolated island of Rokkenjima. Beatrice kills the victims with magic and Battler has to solve the mysteries in a logical and plausible way. Sadly for Battler, Beatrice loves this game and repeats the murders as much as she wants.

Maybe Akemi just wanted to have a normal life and spend her school days with Madoka and her friends without worrying about fighting witches, being a magical girl, or seeing the world end. But sadly, the world of Puella Magi Madoka Magica isn’t as normal as she hoped. Given the power to travel back through time, Akemi tried many times to save Madoka from turning into a witch, and while Akemi did finally change her fate, the end result is equally heart-breaking — Madoka became a goddess and changed the laws of the universe so that she can save everyone, especially the witches, but at the same time, her existence as a human being has been erased.

Driven by despair and the desire to see Madoka, the witch Homura Akemi defied fate and transformed herself into something more than a witch — a being with equal power as a god. Akemi sealed Madoka’s power and rewrote the laws of the universe again, and changed everything back to the way she always wished — a world where Madoka exists as your average school girl.

Love can drive a person to the brink of insanity, and Akemi is not an exception. With her newfound goddess powers, Madoka, friends, the entire world is back to the way they were. Well, for the most part, Madoka still has her goddess powers and Akemi, also a goddess, is no longer the meek and shy girl she once was.

Haruhi is the founding member of the SOS Brigade with the purpose of finding strange phenomena and paranormal activities… really it’s just for finding aliens, time travelers, and espers, and conveniently, they’re right next to her. There’s a reason for that, because Haruhi has the power to change, destroy, and reshape reality.

What makes her dangerous is she’s completely unaware of her power to change the very fabric of spacetime, and has the ability to make something she desires simply just by wishing for it. To make matters worse, Haruhi is extremely moody, so the SOS Brigade will do whatever it takes to keep her entertained and happy. Otherwise, Haruhi can completely obliterate the universe or shape the universe into a dark and lifeless place if she experienced one bad moment.

Her powers include the ability to wish for anything, reshape the world, the ability to alter time, space, and rewrite the general rules of the universe. So with all that said, here’s a very helpful tip, a pro-tip, to anyone who dates a literal god: Don’t cheat on her. It’s for your own sake. And ours. And the universe’s.

While a majority of the OP guy characters prefer using raw power to get the job done, the ladies, well, the majority of them prefer using magic, or magic-infused weapons and ranged attacks. Some of the characters are so magically powerful, they even reach god-like status and change the universe at will or by emotion. This god-like quality is why Suzumiya Haruhi is number 1. She’s not capable of dismembering people like Lucy or has the fighting skills like Saber, but Haruhi holds the power to shape the universe to whatever she wants. She may make the universe a happy place filled with espers, aliens and talking cats, or turn it into a lifeless blob of space in an instant. Depending on her mood, of course.
