History BadassBookworm / AnimeAndManga

* ''Anime/YuGiOh'': Seto Kaiba is one of the top two Duel Monsters duelists of all time, a master chess player, CEO of the world's most successful game company, and inventor of the Duel Disk system, among other high tech gaming gadgets. Oh, and he was also apparently trained well in Krav Maga, and can disarm someone with a card fling.

** [[ArcherArchetype Uryu Ishida]] is top of his school class and student body president yet one-shotted both a Shinigami captain and his Bankai with a single arrow at the age of ''15''. [[spoiler:In the final arc, [[KnightOfCerebus Yhwach]] is so concerned about the threat the now 17-year-old Uryuu presents that he [[KickedUpstairs kicks Uryuu upstairs]].]]

* ''Manga/FairyTail'': Lucy and Levi.

* ''Anime/BattleProgrammerShirase'': Don't mess with Akira Shirase. Yes, he does look like a textbook example of computer nerd, who haven't shaved, washed or got enough sleep in three or four days. He also can listen to a song and write a binary of mp3 of it out of his head. He can also hack your PC into going boom using nothing more than a cellphone with internet connection. Or hack and drop a sequence of decommissioned spy satellites on your head.

* ''Manga/BlackLagoon'': Rock is probably the most dangerous character in the whole series. Not only is does his business and schmoozing experience cause him to be the best negotiator of the Lagoon company he also [[spoiler:plans out the events of an arc before hand based on his limited knowledge of the characters involved.]].

* Manabu Yukimitsu from ''Manga/{{Eyeshield 21}}''. Scrawny and weak, the only thing that even lets him join the team is the fact that he's more of a {{Determinator}} than the character whose determination is a running gag. However, after finally being put into the game against Shinryuuji, he [[spoiler: manages to outsmart [[TheGift gifted]] JerkJock Agon Kongo and score a touchdown.]]

* ''Manga/{{Golgo 13}}'': In the 3rd episode, the titular hitman is in a sniper duel with two mercenaries using advanced rifles superior to his own M16, and modified with a unique electronic "super scope". Based on their firing patterns, he deduces that the scopes have a vulnerability in that they do not take shifts in gradient into account. He then calculates the gradient necessary for their shots to be inaccurate, and positions himself in an area of the battlefield with that gradient, easily blowing them away. Duke Togo - international assassin, and math nerd.

** Johan himself. A bona-fide genius- he once posed as a Law student, but legitimately got all A's, in between advising a tycoon on how to run his financial empire whilst the two discussed Latin- who happens to be a super-prolific SerialKiller, a man who amongst other things slaughters entire families off-screen. He has hardened criminals, mad scientists and Neo-Nazis all worshipping the ground he walks on, and the rest of the world p*ssing themselves in his presence because he just oozes evil. He is utterly fearless (even inviting) in the face of death and has been shot in the head [[spoiler: twice]] and survived. His hobby is walking the edges of skyrise rooftops and he is probably TheAntichrist. Not known for his fighting skill, but he's pretty familiar with guns and was bred to be an {{Ubermensch}}. He is also a ManipulativeBastard of the highest order and seems capable of talking civilization into destroying itself.

** He might be more of a GeniusBruiser, Ranma is definitely well rounded, heck he is probably the most well rounded in skills in the manga displaying knowledge in a large variety of fields (cooking, cleaning, repair work, sewing, horse riding, first aid, CPR, some knowledge on magic, designing (he makes his own disguises in the manga; can be seen sewing a costume before the battle with Mousse - pictured above), tea ceremony, proper manners (though he doesn't always use them), animals, constructed spirit wards (didn't screw them up in the manga only in the anime), dancing (went dancing on a date in the manga), wrote a play and went to see plays), etc.

* ''Anime/FateZero'':

* [[ExBigBad Akihiko Kayaba]] from ''LightNovel/SwordArtOnline''. He programmed all of SAO, and designed the hardware, by himself. Even after his death he created a program that revived the VRMMORPG genre in the aftermath of the Fairy Dance arc.

** ''Anime/YuGiOhGX'': Bastion Misawa is a genius science student who bases his deck around scientific formulas.
