💪 Badass Anime Characters You Don't Want to Mess With, Period! 💪

List is in alphabetical order. Based on anime I've actually watched. It includes both heroes and villains. Each character is taken solely into context of their universe. Plus, very few come from "Overpowered Main Characters" anime since it is much more commonplace. If a deserving character is not on the list, then I probably have not seen the series, movie, special, or OVA. Created: Apr-10-2017

1		Accelerator Series: A Certain Magical Index What appears to be a Sadistic, Hot-Headed punk (or even villain), Accelerator turns out be just another scientific experiment in Academy City. He even shows that he has a good heart, which is good because his power is off the charts. He is the highest ranked 'Level 5' esper! He can control practically unlimited vectors (material/immaterial things having direction as well as magnitude).
2		All Might Series: My Hero Academia Despite his Sickly nature, he still maintains incredible strength, durability, speed, and an assortment of various abilities. If he's able to launch Genetically Engineered Monster's like Noumu, who has super strength, full regeneration, and shock absorption abilities, then you are certainly BADASS!
3		Alucard Series: Hellsing This version of Alucard is considered to be the most powerful or at least one of the most powerful Vampires across all anime lore.
4		Aoshi SHINOMORI Series: Rurouni Kenshin The combination of his Kodachi Nitō Ryū and Kempo fighting style give him excellent balance between defense and offense. If at full strength, he is very near or on par with Makoto Shishio.
5		Azusa AIZAWA Extra powerful slimes, Dragons, Demon Generals, and the Demon Lord are but mere child's play when it comes to how powerful Azusa is, and how she easily defeated them all.
6		Balalaika Series: Black Lagoon; Black Lagoon: Second Barrage OVA: Black Lagoon: Roberta's Blood Trail She has enough military field and tactical experience to start, fight, and likely win a war in any country.
7		Balsa Series: Seirei no Moribito She uses her spear with deadly precision and speed to defeat highly skilled opponents who can be equally fast and use smaller, lighter, and quicker weapons. She knows how to deliberately disable them without having to kill them. Plus, she can do hand-to-hand combat with great ability as well, if needed. That's how good she is.
8		Broly >>User Submitted<< Movie: Dragon Ball Z Movie 8: Broly - The Legendary Super Saiyan Without getting into the specifics of the Dragon Ball Universe (DBU), it takes the strength of Super Saiyajin (SSJ) Goku, who is arguably the strongest fighter in the DBZ time line, enhanced with the powers of SSJ Vegeta, SSJ Gohan, SSJ Trunks, and Piccolo in order to stand a chance against Legendary SSJ Broly. In DBU that is a vast amount of energy needed to defeat a single foe. Damn!
9		Cid KAGENOU
10		Claire STANFIELD Series: Baccano! Specials: Baccano! Specials He is an incredibly gifted assassin. He is in above peak human shape with Olympic level strength, speed, dexterity, and super human agility.
11		D Movies: Vampire Hunter D; Vampire Hunter D: Bloodlust The half-human, half-vampire dhampir has defeated opponents thousands of years old and extremely powerful. He definitely gets his power from his father's side.
12		Dracula Series: Castlevania This is a super powerful version of the most infamous Vampire in all of lore. To sum up his badass level, three capable badasses themselves (Alucard, Trevor, and Sypha) are not strong enough to defeat him, even when he is in a clearly weakened form! There is no way to officially measure it, but based on what he shows when not weakened, he probably is at about 25% strength when going up against them. Damn!
13		Escanor >>User Submitted<<
14		Eumiella DOLKNESS
15		Firo PROCHAINEZO Series: Baccano! A young Immortal who is not only a really nice kid, but also a smart and very skilled fighter both with a knife and without one. He's trusting to a fault sometimes, but he won't hesitate to kick someone's ass should they betray his trust.
16		Franken STEIN Series: Soul Eater One of the strongest characters throughout the entire series. His abilities and intelligence are practically without equal.
17		Gabimaru Series: Hell's Paradise: Jigokuraku The guy can survive practically anyone or anything that he is up against. Literally. If that is not enough, he has the ability to engulf his entire body in flames and incorporate them into his advanced-level Shinobi-ninjitsu techniques.
18		Gauron Series: Full Metal Panic! A tactically intelligent and very skilled Mecha Pilot with more lives than a cat.
19		Goblin Slayer Series: Goblin Slayer He knows how to effectively use whatever weapon he finds on a quest, including during battle. He knows how to use archaic magic scrolls. He knows how to strategically ambush a horde of 100+ goblins, who are known for their ability to ambush others. Even after taking a beating, he gets up and continues to fight and at a smart, high level. Finally, he is fearless and is not intimidated no matter the enemy or the odds.
20		Hajime SAITOU Series: Rurouni Kenshin Known as the 'Wolf of Mibu,' he is a top level swordsman who is hard to defeat with his special Gatotsu sword technique.
21		Ikki KUROGANE Series: Chivalry of a Failed Knight In the shows universe he has very little magic power, which gives him an 'F' grade in his school of magical knights. However, his combat prowess with his sword is above the 'A' students. He's in a class all of his own.
22		Ikta SOLORK Series: Alderamin on the Sky He can handle himself in a fight acceptably for a solider. However, is real badass nature comes from his mind. Solork is clearly of genius intellect as he out manouvers an army of 12,000 (compared to his 600) and out smarts a nearly equal strategist. He's practically fearless in both action and words, which does get him into a bit of trouble sometimes, but not to something that he doesn't resolve. A true Analytical badass among men.
23		Jin Series: Samurai Champloo Incredible with a sword, he is almost undefeatable. In a dojo setting, he probably is undefeatable.
24		Kagura TSUCHIMIYA Series: Ga-Rei -Zero- A naturally gifted excorcist at a very young age, she can sometimes let her feelings cloud her judgement. However, when her mind is clear and focused, she is not someone who should be messed with.
25		Kambei SHIMADA Series: Samurai 7 The wisest, oldest, and most battle tested of all the seven samurai, he can defeat most opponents with relative ease.
26		Kanade TACHIBANA Series: Angel Beats! Kanade Tachibana is without equal in the series. It takes the entire Afterlife Battle Front just to slow her down, not even defeat her! They've got guns, rocket launchers, long-ranged melee weapons, and more. Non of that is enough to defeat her! Damn!
27		Kaname KURAN Series: Vampire Knight; Vampire Knight Guilty All other vampires undeniably respect his power and 'pure blood' vampiric lineage. He hardly shows his abilities but when he does, watch out!
28		Kelvin
29		Kenshin HIMURA Series: Rurouni Kenshin Movie: Rurouni Kenshin Movie OVA: Rurouni Kenshin: Tsuiokuhenn Personal favorite character who is almost invincible with the use of his God-like sword style, Hiten Mitsurugi-ryuu.
30		Kirukiru AMOU Series: Armed Girl’s Machiavellism She is a practioner of Karate. However, this is not what makes her a tough opponent. That credit goes to her ability to harden her entire body as if it were steel. Doing so makes her hands like blades themselves. Her nearly impenetrable defense and deadly 'hand-blades' make her badass!
31		Koro-sensei Series: Assassination Classroom He merits being on this list for reasons including, but not limited to: His Mach 20 speed, can dodge rapid-fire gunfire from short range, and his extremely high intelligence.
32		Lucy Series: Elfen Lied A Diclonius of the utmost power. She can destroy at an alarming rate and without hesitation or compassion.
33		Maple Series: BOFURI: I Don’t Want to Get Hurt, so I’ll Max Out My Defense. She is the personification of ultimate defense! Her lack of video gaming experience is what created this monster of a character. Her very first online player event had me LMAO on just how awesome her vitality and defensive stats really are. The “game mechanics” created by the anime’s creators are unrealistic, but who cares; Maple is so innocent and fun to watch!
34		Medaka KUROKAMI Series: Medaka Box She's the One-Punch Man of her anime's universe. She's at the top of her school in everything that she so desires to be.
35		Mikoto MISAKA Series: A Certain Scientific Railgun As only one of seven 'Level 5' espers (ranked #3) in all of Academy City, it's hard not to see why. Whenever you think she's been bested by either another powerful esper or someone who has significantly studied her powers in order to counteract them, she ups her game with either an amazing ability or in just shear raw power. Her hard work, mental capacity and knowledge of her own 'personal reality' is what elevates her above the rest.
36		Mirei KUDOU Series: When Supernatural Battles Became Commonplace If you've seen the anime before, you might be wondering why she's on this list. Simply put, when you have the ability to completely steal all other Superpowers, including more than one at a time, then that makes you quite powerful and potentially dangerous.
37		Mitsukuni HANINOZUKA Series: Ouran High School Host Club His sweet, boy lolita nature is only a part of who he really is. He is a master Martial Artist who can defeat other well-known martial artists. The best part is...that's not the kind of person he wants to be. He's just a natural-born badass!
38		Momo Series: The Executioner and Her Way of Life She is Ruthless and extremely jealous. When those two characteristics are combined along with her getting enraged, what do you get!? She gathers so much ether that punches a dragon to death before blowing up half a castle. For an encore she uses the leftover magical power from the dragon to destroy a powerful barrier before kicking the ass out of an extremely tough angel-like magical creature. Lesson learned? Do not keep Momo from being with Menou, her mentor and the only person she cares about, period!
39		Natsuki MINAMIYA Series: Strike the Blood The Witch of the Void is responsible for maintaining the imprisonment of dozens of other magical criminals, while still being able to perform her daily responsibilites as an English Teacher. To further bolster her prowess, she strong enough to hold her own against Kojou, Yukina and Kiriha at the same time.
40		Punie TANAKA OVA: Dai Mahou Touge Even when she faces tough competition, she finds a way to defeat her opponents whrther with magic or in physical combat. She can go from cutsey to deadly almost instantly.
41		Revy Series: Black Lagoon; Black Lagoon: Second Barrage OVA: Black Lagoon: Roberta's Blood Trail She is an excellent shot with a variety of weapons, especially her two custom Cutlass specials. She has excellent endurance and is more agile than she may first appear to be.
42		Roberta Series: Black Lagoon: Second Barrage OVA: Black Lagoon: Roberta's Blood Trail She is like a machine when we first see her in action. She's good enough to slightly best Revy in a no holds barred fight in Black Lagoon: Second Barrage. In the OVA series she takes her abilities to even new levels...scary!
43		Rory MERCURY Series: GATE; GATE (2016) An over 900 year old Diety, Rory has the power, ability, and fearlessness to take on a flame dragon! Although not capable of defeating one, the fact that she can fight one and survive is a testament to how awesome she is. You don't want to mess with her!
44		Saber Series: Fate/stay night A naturally skilled fighter with her sword, her Noble Phantasm makes her God-like and undefeatable in the Fate/stay night series. Series: Fate/Kaleid Liner Prisma Illya A much different of character in this series, she has immense power and a unique ability unlike any other faced. Put her against the Berseker character and the battle would be nothing less than a draw for Saber in my opinion.
45		Sagiri YAMADA ASAEMON Series: Hell's Paradise: Jigokuraku If Gabimaru even respects her strength and fears her sword, then that says something from one who is as close to being unbeatable as they get. She is one of the few characters to be included on both this list and this list as well.
46		Sara Series: Samurai Champloo She could be considered the second best fighter in the series due to her exceptional hearing and mastery of her ranged melee weapon.
47		Sebastian MICHAELIS Series: Black Butler He is a powerful Demon who is centuries old, immortal, and can take down angels like there's no tomorrow, even when completely missing an arm. On top of all that, he's simply 'one hell of a butler' as well.
48		Seijuro HIKO Series: Rurouni Kenshin OVA: Rurouni Kenshin: Tsuiokuhenn Kenshin Himura's master who taught him Hiten Mitsurugi-ryū. He was stated by the creator of the Rurouni Kenshin universe to be powerful enough to defeat Kenshin's enemies easily, including Makoto Shishio. What little we see him actually fight in the series, it is clear that Hiko is very powerful indeed.
49		Sen YARIZUI Series: Ben-To When she's at 100% health, NO ONE can keep her from getting a half-priced ben-to box. NO ONE!
50		Shota AIZAWA Series: My Hero Academia He can neutralize any other hero or villain's abilities and is a very capable hand-to-hand combantant as well. Enough said.
