Awesomeness by Analysis in Fan Works.
Crossovers
- The Boys: Real Justice: Batman's greatest strength is his detective skills. By observing the microaggressions of Homelander and Victoria Neuman, he can determine the former's mental instability and that the latter is a plant of Vought.
- Child of the Storm:
- Chapter 70 of the first book has Albus Dumbledore casually analyse the casting styles of four HYDRA assassin wizards sent to kill him, defeat them with a couple of spells, then destroy their wands with another, without even giving them more than half his attention.
- The Winter Soldier's inner monologue is depicted as a computer-like piece of tactical analysis, interspersed with rare moments of humanity, which he uses to systematically discern and target his enemies' weaknesses, usually to lethal effect.
- This is part of the core of Strange's modus operandi - he figures out exactly what makes people tick, aided by his powers as a Seer, and then proceeds to use both sources of knowledge to play everyone like a harp (which, since he was a literally legendary bard as a hobby when he was known as Taliesin, means he's really good at it).
- In the Children of Time rewrite of "The Shakespeare Code," William Shakespeare is more awesome than ever, able to deduce quite a lot about Sherlock Holmes and Dr. John Watson.
- Avis in Code Geass: Ashikabi of the Amour
determines humanity's evolutionary history by feeling Lelouch's bone structure, even able to tell that Earth's creatures have an unusually high amount of calcium in their bones. - Equestria Girls: Friendship Souls happens quite often, but the most prominent examples:
- Rarity, who defeats Blueblood, a Captain of the Gotei 13, not through brute force but by carefully observing his movements and the workings of his Shikai in order to eventually neutralize him before he can activate his Bankai.
- Twilight naturally is able to do this thanks to her incredible intelligence working with the battle adrenaline allowing her to analyze and predict the most likely course of action they'll take.
- Fate Revelation Online:
- Shirou's Structural Analysis. He's so good at it that he manages to accidentally go into the system and discover how to make steel. Outside of his magecraft, Shirou's skill in analyzing his opponent's style allows him to custom-tailor weapons perfectly suited to them.
- Grimlock is exceptionally skilled with magecraft and can easily identify ways to improve or counter any spells he encounters. As a magus he has experience, and he can determine the weakness in a quest boss's bounded field as well as point out how his party could have killed it instantly with a curse.
- Izuku Midoriya in For Great Justice manages to figure out the secret identities of everyone in the Justice League by the time he meets them along with the rough location of the Batcave. Batman suspects the boy's probably calculated the locations of Themyscira and the Fortress of Solitude.
- In A Great Endeavor, Twilight ends up as an adviser to the Allied forces at Bastogne, initially treating the strategy "as a big logic puzzle".
- Jedi Master Sinube in The Havoc Side of the Force shows he was sent to speak with Harry Potter for exactly this reason. From a brief conversation, along with comments by others, he figures out pretty much the entirety of Harry's life story (at least on a general level) including that he's from the distant future and was himself a child of prophecy.
- In Hunters of Justice, Weiss is able to deduce that Bruce Wayne is Batman from hearing that Dick's last name is Grayson, meaning he is the Dick Grayson, adopted son of Bruce Wayne, then simply puzzling out the timeline between the adoption and Dick meeting Batman, as well as how, regardless of how much he acts like a Upper-Class Twit, Wayne would have noticed his son sneaking out to be a vigilante, meaning there would be no way for someone as young as Dick was at the time to meet Batman, train with him, and become Robin, without his father noticing unless Bruce Wayne was Batman.
- In iFight Crime With Victoriousnote :
- Freddie Benson has this as his main power, and it doubles as healing and triples as an Adaptive Ability. He uses this to diagnose the functions of his own ability and the abilities of his friends.
- Neville Papperman performs a similar task with his "fear-sense", but he does this by figuring out the person's vulnerabilities and concerns over their power and working out how it functions. He analyses their fear, which typically relates to their newfound power.
- In Imaginary Seas, both Chirons are capable of this. Lostbelt Chiron smugly points out the delay between Percy's swing and the lasers coming down from the sky, alternating his rate of fire to in an attempt to overcome Percy's defenses. Pan-Human Chiron runs the same calculations to counter Lostbelt Chiron's arrows and runs a Batman Gambit based on what he knows about himself and the gods of the Lostbelt to keep Artemis from simply nuking the island.
- Pretty much the Omega's main advantage in Left Beyond: the distributed AI are capable of generating excellent, although not perfect, probability spreads for the sysadmins' plans. Somewhat subverted in that the Omega are fighting God in-universe... and the dice out of the universe, in that God keeps getting ridiculously good rolls.
- The Last Seidr: Black Widow is able to deduce a large amount of shockingly accurate information about Harry Potter after simply watching security footage of him (namely the fact that he's an orphan, he's been abused, he generally doesn't trust authority figures, he's not unfamiliar with being in dangerous situations, he's very fond of Fawkes, etc).
- Lulu's Bizarre Rebellion: As in Jojo canon, Anubis has the power to memorize and counter any attack after it's used against him once. As Anubis Requiem, this also applies to any plan or technique known by anyone in the radius of Mao's mind reading geass.
- Maria Campbell of the Astral Clocktower: Katarina, of all people, demonstrates this when learning to fight with a scythe; Maria wants her to get used to more exotic weapons. As she's a proud farmer, she goes on a long rant about how a scythe is not designed to be a weapon, and if you have time to build a scythe for combat you may as well just pound the blade straight and turn it into a sword. Apparently traditional scythe combat involves a lot of inefficient slash attacks and trying to stab the opponent with the point. Katarina is especially offended by that last one, as she says that a scythe doesn't really have a sharpened point, it's just the part where you stop sharpening the blade. Then, using her knowledge of what a scythe was actually designed for, she demonstrates "advanced" scythe techniques mostly revolving around low, sweeping attacks using the full staff as leverage—in other words, as if she was harvesting wheat.
- In Mass Effect: Human Revolution, Adam has a Sherlock-like ability to read an opponent's fighting style and plan an elaborate counter. And just like Downey's rendition of Holmes, it falters when he can't read the foe or isn't given the time and space to plan.
- In The New Man: An Adam Smasher SI, Adam Smasher trains David Martinez this way. He takes the boy to watch him kill various assorted gangoons and then has him give an on-the-spot breakdown of how he fought them and why he made each tactical move he did.
- "The Not-So-Average Girl” gives Kim Pierce (a variation of Kim Possible) the power of enhanced survivability in Heroes. As described by Claude Raines, Kim’s power allows her to immediately take in her surroundings when she is in a dangerous situation and instinctively act to save herself, whether adjusting her position as she’s flying through the air after being thrown so she doesn’t hit a wall head-first or moving to jump on and then off a truck that was about to hit her. Kim’s ability also justifies her academic performance, as she learns various skills that will help her understand people or survive in dangerous situations, but it is noted that she isn’t good at home economics as she doesn’t need to know how to cook to survive (either she’s somewhere where she can buy food of some sort or she’s out in the wild and only needs to know what won’t poison her until she can get back to civilization).
- The Spectacular Spider-Man: Lost in Gotham: It takes Spider-Man all of five minutes to realize that he was sent to another dimension. All he needed was a local newspaper and a look at Gotham's skyline.
- to forget is unforgivable: As per canon, Izuku displays incredible analytical skills, and now that he's a vengeanceful cursed spirit, he is able to apply that knowledge.
- In My Shovel Tells A Secret, he is able to successfully analyse the cursed technique of the special grade curse Shigaraki brought with him, form an effective plan to defeat it without damaging anything or getting anyone hurt, and then merge Miruko and Edge-Shot's fighting styles to take it down.
- In The Curse Is Okay, But The New Guy Is On Thin Ice, he figures out how Principal Yaga's cursed corpses work within minutes, and later he is able to come up with different applications for Fushiguro's "Ten Shadows" technique.
- In Learning Curves, Izuku figures out how to hold off Ryoumen Sukuna for a full minute of sparing without injuring his vessel Yuji in the process, using a careful combination of lightning strikes, Pressure Points, and an analysis of how Reversed Cursed Techniques work to take the upper hand.
- The Totally Amazing Spider-Man: Sam is able to pick up on Spider-Man's spider-sense by noticing how he was able to shoot his web- or from her perspective, "fire his cable", without even looking where he was firing.
- Wonderful (Mazinja): Lisa has the ability to find out information about people or things. She only needed to observe a house-sized tank to discover its strong and weak points.
- In the Journeyverse story When Titans Clash, Jarod shows this as he is able to quickly determine the nature of his opponents as millennia-old immortals while defending himself from the same.
- In Ordinary Girl, with nothing but stray documents to go on, Jesse was able to figure out that Unless You — a novel being passed around amongst Bureau staff — is actually an Altered Item that is killing its readers and manages to get it away from Emily before it could take effect.
- Saito, due to his work as a military spy in Soldier of Zero is quite adept at figuring out both people and powers, though he sometimes makes mistakes due to differences between his world and Halkagenia. For example, in his world making a golem is one of the most difficult pieces of magic there is, but in Halkagenia it's fairly basic. On the other hand, he figures out Tabitha's life story from a minor story about her dueling Kirche once and looking at her habits. Such as Tabitha having to go with little to no food at times from the fact she's sixteen but short enough to be confused for a preteen (a sign of malnourishment).
- Fate/Gamers Only: One of Rikku's greatest strengths is her ability to assess the strengths and weaknesses of the enemy Servants. She credits it to playing lots of video games. It subsequently turns out her analytical skills are boosted by her magical enhancement.
- Lucius Malfoy in Dodging Prison and Stealing Witches is a retired duelist who can learn a great deal about someone from their casting and dueling techniques. After seeing Lord Slytherin duel once, he realizes the man fights exactly the same way Voldemort does. After the dueling tournament, he notes the same of Harry Potter, causing him to believe both are people who were taken over by one of Voldemort's horcruxes. He's wrong but literally the only other person to figure either out was Voldemort after spending months observing Harry.
- In a Harry Potter and the Methods of Rationality omake about what it would look like if it was about The Lord of the Rings, Frodo implied that even if Evil Could Not Comprehend Good intuitively, that won't keep Sauron from figuring it out this way.
- Sixes and Sevens: Sue Storm first ingratiates herself with Peggy and company when she sees the altered equations from Isodyne Labs and is able to not only determine the correct version but deduce a major part of Cassandra Romulus' plan (opening a wormhole to access more zero matter). She's later able to figure out how the radio typewriter looks just by looking over it for a moment, which highly impresses Jason Wilkes.
- The Adventures of Panthera Noire: Lila always had the habit of analyzing everything around her to better tailor her lies. While she doesn't pull her mass lies anymore, she strongly suspects Gabriel of being Hawk Moth purely by the timing of his akumatization and that he hasn't come out of his home since before Hawk Moth started akumatizing people.
- Feralnette AU: Adrien gets to see this in action when Nora is akumatized into Anansi again, as Marinette starts rambling about her biggest weaknesses—that beneath the akuma magic is a human mind that can't parse having multiple limbs, and whose body structure is weaker than it seems.
- A common sight in the For the Want of a Nail Series:
- The premise of Mastermind: Strategist for Hire involves Izuku putting his analytical skills to use making plans for other Villains, which leads to him rapidly becoming one of the most respected and feared Villains in Japan.
- During the USJ attack, Izuku rapidly works out that Shinsou has some form of brainwashing that is likely triggered by talking to him.
- Later on, whilst the League of Villains are planning an attack on a UA training camp, Izuku works out Dabi's true identity as Touya Todoroki, Shouto's brother, from his teal eyes, his Quirk and his hatred of Heroes, particularly Endeavor, to Dabi's shock.
- In Deku? I think he's some pro..., Izuku's skills at analysing Heroes and Villains initially get him mistaken for a retired Pro Hero with an intelligence/analysis Quirk by several underground Heroes. Their shock at them finding out he's a Quirkless teenager ends up growing when they learn he was using only the evidence they had sent him for analysis (meaning, among other things, he had provided a sufficiently in-depth analysis to catch a serial killer with only 15 seconds of video to work with).
- A later chapter has Izuku working out One For All's existence - by researching other Quirks that suddenly mutated to include Super-Strength, Izuku discovers a number of heroes who each suddenly gained super strength, and had either a mentor or apprentice who did likewise.
- Cheat Code: Support Strategist has Izuku attending UA's Support course, choosing the Intelligence and Analytics Track, with the intent of putting his analysis abilities to use helping other Heroes.
- Early on, Izuku passes the written portion of the Entrance Exam with flying colours, with Power Loader describing his portfolio as impressive.
- Iuzku showcases his investigative prowess early on in Shadows: The Horror Movie Heroes - driven by his curiosity regarding Shinsou's brainwashing, he manages to find out which school he went to and track down where he lives less than a day after meeting him.
- The premise of Mastermind: Strategist for Hire involves Izuku putting his analytical skills to use making plans for other Villains, which leads to him rapidly becoming one of the most respected and feared Villains in Japan.
- Hero Class Civil Warfare: Izuku, assigned to be the leader of the Villain Team in the game, turns in an entire booklet to their teacher before the exercise that, to their teacher's astonishment, describes everything that is about to happen in the game, every tactic Izuku suspects the other side may use, every backup plan for his backup plans, who each of his teammates should fight or flee from based on their abilities, fighting style, and psychology, and an intensive analysis of every single player in the game, along with their strengths, habits, and weaknesses. The booklet is titled "Stage Directions." Armed with this knowledge, Izuku proceeds to become the first Invincible Villain the exercise has ever had.
- Heroes Never Die: Izuku is even better than in canon since he's been trapped in time loops on a regular basis for his entire life and had to find ways to escape.Ashido: [thinking] He wrote out five different play-by-play scenarios in the time it took us to walk here? I'm glad he's on my side.
- Locked In Digital: Canon!Izuku is already shown to be a very skilled analyst, being able to quickly deduce strengths and weaknesses of quirks and fighting styles. Here, this skill has been further honed by his simulation run, to the point he can find minute details and come to accurate or near-accurate conclusions. For example, he immediately figured out that All Might has a Game-Breaking Injury on his torso that was received between 2 to 8 years ago, and pinpointed Yaoyorozou's self-esteem issues, both based on their body language.
- Looping Back to the Beginning:
- An Izuku who hasn't regained his memories yet manages to figure out Class 1-A's looping nature rather easily as soon as he notices something weird is going on (in one of the loops, it's because Katsuki actually thanked him for trying to save his life from the Sludge Villain). All Might was so impressed by his student's work that if he hadn't already chosen the kid to be his successor, he would've pushed him toward the police.
- Toga Himiko concludes that Shoto is a time traveler and that Izuku is a part of his group during the loop he spends with her and Dabi (with Izuku as a vigilante who happens to encounter the trio; it is immediately after this encounter that Himiko makes her conclusion).
- Despite not being part of the loops, the final chapter reveals that Principal Nedzu figures it out almost immediately and considers it so obvious that he forgets it's not so for other people.
- In Quirk: Sequencer, Nezu quickly figures out Izuku's lying about his Quirk by analyzing his Combination Attack and figuring out all the discrepancies between his previous uses of Plasma Cannon. This is all before he spots footage of Izuku creating a raven from the ink on his back. On a lesser scale, Izuku's classmates notice how odd it is that his Plasma Cannon usually has no noticeable recoil but other times he uses it to get a Recoil Boost. Izuku has to quickly make up an explanation to hide his other Quirks.
My Little Pony: Friendship Is Magic
- In By Royal Command, Trixie turns out to be an excellent profiler and personality reader, as part of her chosen occupation. When she receives an incredibly indecent letter without a readable signature and the claim of being written by a princess, Celestia asks her what she can determine about the author—Trixie determines that the writer is female, extremely educated, was socially undeveloped for most of her life and only lately started to develop interpersonal relationships outside of her immediate family, and has no sexual experience whatsoever. It doesn't take much work for Celestia to figure out who that is.
- A Moon and World Apart: In chapter 24, Twilight and Shining Armor teleport out of her apartment and into one of the other domes together. Seconds later, Sunset Shimmer teleports after them, having traced the initial teleport and followed it; when she explains this, Twilight is quite impressed.
- Androgyninja's A Drop of Poison: Sakura does her best to compensate for her limited resources by honing this skill, reading and teaching herself as much as she can about poisonous plants and animals long before she's able to start working with actual materials. She also uses this alongside her incredible chakra control to slowly and painstakingly teach herself how to use the Mokuton.
- Hinata's new technique in A Drop of Poison relies heavily on trigonometry to calculate how her chakrams will ricochet around an area, eventually building in dozens of the blades flying through the air as she catches and flings them around. While it has a bit of build-up time, once she gets going, it's near impossible to approach her due to all the razor-sharp metal flying around.
- I Am NOT Going Through Puberty Again!: The Third Hokage knows of the time travelers, and that Naruto was Hokage in the future (even if he got the number wrong). He deduced it by observing how they acted and the extent of their abilities.
- In Kitsune no Ken: Fist of the Fox, Shikamaru (who already has this going for him in the canon series), ably demonstrates this during his fight with Tenten in Sasuke's tournament; specifically, he deconstructs her constant pattern of attacking without defending while he takes every opportunity to grope her in order to prove his point.
- In the Self Insert story Vapors, most people think of Aiko as a Fragile Speedster with whip-based ninjutsu. But while she doesn't often flaunt it, Aiko is very good at this, as evidenced by her ability to recreate and improve the Hiraishin on her own, successfully plan to take out most of the Akatsuki, learn how to seal a biju in under a month, and direct Danzo's Root seal until she can remove it and reapply it with ease.
- Advice and Trust:
- In chapter 5, Rei notices that Shinji and Asuka smell of chlorine, ammonia, dust, and each other. Quickly she deduces that: they just had sex; they are together; they are keeping it a secret, and the reasons for the secrecy. And she guesses all that just by sniffing their scent!
- Later Shinji and Asuka realize their mothers are stuck inside their giant robots just by talking about their pasts and their experiences piloting Eva and comparing notes.
- This Bites!:
- Scratchman Apoo figured out Soundbite's transponder number by a slight noise he makes during SBS broadcasts which told him what model the transponder is, then calling shops in Loguetown to find out who sold it. During the Enies Lobby arc, he was able to figure out that Foxy is allied with Cross and then coordinate an attack with both them and the Kung Fu Pirates on 'Task Force Cerberus' before they can join the forces on Enies Lobby.
- Law determines Luffy isn't dead yet while fighting Lily Carnation because he can tell where each attack hit purely by sound and none are instantly fatal.
- Ash in Common Sense since he was Taught by Experience from his battles with Team Rocket. And after Pikachu demonstrated a knack for it too, he started training all of his Pokémon to do so when commanded to "analyze". This led to him beating Lt. Surge on his first try with Pikachu.
- Reggie in Pokéumans delivers a beatdown to the MSN Gang while analyzing their (appalling) tactics as he went and giving a "The Reason You Suck" Speech. Levels in badass were taken.
- In A History of Magic, Queen Himiko studied other Puella Magi to learn their skills and abilities.
- Akane and Shampoo show this in a later chapter of Desperately Seeking Ranma. It results in Akane screwing over some crooks before they can even start their heist.
- Tsukune in Here In My Arms demonstrates this trope to defeat Inner Moka.
- In Ruby and Nora, Pyrrha manages to figure out Mercury’s legs are prosthetics before she even uses her semblance on them.
- In Intrepid, Taylor triggered with this ability during combat situations. She can analyze and process information enough to predict where bullets will strike, how to block or deflect them, and just be a plain badass.
