Most of the Ace Combat games turn you into this during the course of the story. It is quite awesome to hear other pilots on the radio shit their pants when they learn you've entered the battlefield.
Most notably in the fifth game of the series; the protagonists become so feared by the enemy they are given the nickname "Razgriz" (after a mythical demon with a penchant for leaving death and destruction in his wake) and the mere mention of them is enough to cripple morale.
Terrified Yuktobanian Soldier: Help us! It's the Razgriz!
This is how the Karma Meter works in Medieval: Total War, with a Chivalry-Dread axis. Generals earn Dread points by fighting dishonorably, executing prisoners of war, or exterminating the populations of captured cities. On the strategic map such characters will reduce a settlement's growth and tax income, but increase public order. On the battlefield Dreaded generals reduce the morale of opposing forces, and a sufficiently infamous general can cause entire armies to rout simply by charging. These characters often pick up appellations such as "the Tyrant," "the Wrathful," or "the Merciless."
Joel is The Dreaded throughout much of The Last of Us whether it's in the Boston Quarantine Zone, Pittsburgh, or Utah. In the Boston QZ he is feared as a dangerous smuggler with plenty of connections, in Pittsburgh he is simply the 'Man in the Truck' who mercilessly slaughtered patrol after patrol leaving no survivors, and among the Cannibals he is known as the crazy college man. This gets to the point where the cannibals are actively running away from him in a fight. Ellie also earns the status of The Dreaded among the Cannibals for her bloody escape from the college and the Roaring Rampage of Revenge she goes on in their town later on.
Someone in Fable or its sequel who is both famous and evil will cause non-combatants to run at the sight of you. Particularly if you start attacking, or if you've just been for a bit of town-burning previously. You'll never be totally feared though, some brave (and foolish) soul will summon up the courage to call you out on your crimes, and the guards will always do their best even when its a lost cause.
By the midway point of Far Cry 3, Jason has gone from being a kid at the wrong place and wrong time to making pirates soil themselves at the mere mention of Snow White.
In Far Cry: Instincts, the XBox360 version of the original game, for a while you become the monster movie monster, the creature lurking in the dark that messily kills people one by one.
Giygas of EarthBound is a physical manifestation of people's fear.
Dot Hack GU: Haseo, the hero, is nicknamed "The Terror of Death". Most Player Killers he runs into throughout the game will invariably be terrified at the sight of him, and even some random normal players will react in fear upon passing him in the streets. It doesn't help that he styles his usual look after The Grim Reaper and wields a massive Sinister Scythe as his weapon of choice.
Joker: Now, don't worry, boys. I'm sure there's no truth to the rumors that Batman drinks human blood.
In Arkham Origins Batman lays out a measured exposition of all the hired assassins' backgrounds and strengths to Alfred, calmly explaining their histories, until he realizes that Bane is one of them, at which point he only says "Bane... here in Gotham?"
Similarly, in Armored Core games, the player starts out as a relatively unknown rookie, before quickly working himself up in the ladder and becoming a renowned and feared pilot, usually to the point where the local The Chessmaster decides they are too dangerous to leave alone and tries to eliminate them, usually by ambushing them with multiple high ranking AC pilots.
The phrase "It's Lu Bu!" strikes fear into even the mightiest player! And every other general on the field... "Do not pursue Lu Bu" indeed.
Lu Bu's erstwhile subordinate Zhang Liao gets this reputation among the forces of Wu, where his appearance causes the armies of Wu to flee in terror at He Fei.
Shu's Guan Yu is so feared that it takes a combined strategy between Wu and Wei specifically to kill him.
Final Fantasy VI: Emperor Gestahl's around? No problemo. General Leo? He's a cool guy. Kefka's here!? Oh, Crap!. It gets more pronounced as the game goes on, too.
In Final Fantasy VII, Sephiroth is spoken of with a combination of hate, reverence, and fear; the suggestion of his presence is enough to cue an Oh, Crap! from the heroic characters, especially Cloud, who knows him best.
Final Fantasy X: Sin is dreaded all around Spira. It's huge, insanely powerful and solely bent on causing destruction wherever it goes. It's also near-indestructible, as most people believe that only a summoner's Final Aeon can kill it; and even then, it always comes back, eventually.
in Warframe, the Grustrag Three are so intimidating for their sheer power and efficiency in capturing Tenno that the Lotus will immediately abort the mission you're on and demand you get to extraction ASAP before they are able to lay their hands on you.
The Tenno themselves, during the days of the Orokin, when they were viewed as terrifying myths. Their actual deployment was a sign that the Sentients had pushed the Orokin past the Godzilla Threshold.
The title character can become this, depending on player actions. If her body count increases rapidly, then both Tasen and Komato logs reveal many of their soldiers to be pants-wettingly terrified of the implacable "human anomaly" that's been tearing a bloody swath through everything they throw at her. Even if Iji's on a Pacifist Run she still scares the hell out of everyone on the field, partially because she's somehow able to make her way through a warzone without killing anything, and partially because she's collected so much ammunition that they're worried she'll become a miniature black hole.
Annihilators are so feared by the Tasen that one Tasen Soldier writes in a logbook that if they ever face one in battle, they're just going to lie back and hope for a quick death. And even by those standards Iosa The Invincible is regarded as such a terrifying death machine that after Iji kills her several Komato logbooks say that they're glad she's gone.
The Master Chief is referred to as "the Demon" by the Covenant. You get that kind of reputation after massacring thousands of Covenant troops and utterly destroying Halo, a sacred and seemingly indestructible installation built by their gods.
The other Spartans are also referred to as "Demons".
The Halo 2 Anniversary terminals reveal that Thel 'Vadam was this to the UNSC before becoming the Arbiter, as he was the Covenant's greatest commander.
The Primordial/Captive/Precursor/Gravemind introduced in The Forerunner Saga; it's not really a publicly known figure, but to those who do know what it is, the revelation that it's loose inspires shock and fear.
Pyramid Head is this to the other monsters in Silent Hill 2. It's so bad that if James equips PH's Great Knife, turns off his flashlight and drags it along, the signature scraping sound will cause enemies to flee.
Luca Blight from Suikoden II, a genuinely terrifying combination of Ax-Crazy and One-Man Army. To the point that even his own kingdom fears him and hardened warriors such as Viktor and Flik, who in the previous game faced down an Eldritch Abomination, don't even consider battling him unless they have an entire army on their side.
Assassin's Creed I: Altaïr is implied to be viewed this way in general, but it's definitely shown how much he freaks some of his targets out the further you progress into the game, to the point where one of them is so paranoid that he brutally slaughters a defenceless, elderly scholar simply because the man is dressed in white.
Ezio's reputation as this is Played for Laughs with Duccio de Luca, who is on the receiving end of a beat-down from Ezio in II and Brotherhood, due to cheating on his sister in the former and a foolish attempt to get even in the latter. By the time of Revelations, when he realises that Ezio is standing behind him when he's flirting with Sofia, he simply screams and runs in terror.
Edward Kenway in Assassin's Creed IV: Black Flag is so scary that even Blackbeard won't cross him and tells others that they would be wise to do the same. Of course it's revealed it's just Abstergo manipulating events to sell Edward's memories as a cheesy pirate movie.
Assassin's Creed: Rogue: Shay Patrick Cormac is this... for the Assassins. As a former member of The Brotherhood he knows every tactic and dirty trick in the book, and can get the surprise on every assassin he comes across. You would think that an organization of highly trained killing machines would not be concerned about one person interfering with their plans, let alone be afraid of anyone. Yet in less than six years Shay manages to near single-handedly tear apart their firmly established criminal empire, and wipe out every major assassin in the Colonial branch of the Brotherhood, all while shrugging off or foiling all of their attempts to kill him. Even an Assassin like Charles Dorian can recognize him on sight.
Samara, as well as all asari justicars, are famous for their relentless pursuit of justice and their brutal methods in doling it out. When Samara appears on Illium in pursuit of a particular criminal, the police force finds itself on edge, worried that she'd very easily turn on them if they tried to detain her.
Shepard themselves comes off as this to the Reapers. By the end of the second game, the Reapers are forced to admit that Shepard is actually a hindrance to their plans, the first and only time they ever admit such a thing ("Shepard. You have become an annoyance."), and in the third game every Reaper has top-priority "Kill On Sight" orders for Shepard personally, even turning their guns away from fleets in orbit, to kill this one human. In the LeviathanDLC, the Leviathans state that Shepard is the first thing in history (a history stretching back over a billion years, mind you) that the Reapers have ever feared. In the Twitter feed tie-in for Mass Effect 3, while the Reapers have dismissed all opposition with a tone of casual indifference, during their invasion of Earth a priority is issued for confirmation that "Hostile Target Shepard" is dead. When none comes, the Reapers actually get worried about the possibility that s/he's still alive.
This extends to a lesser (though still major) opponent: Cerberus. When Shepard arrives at the Alliance base on Mars during the prologue and finds that Cerberus has arrived and taken it over, the first reaction of the Cerberus troops when Shepard opens fire is essentially "Holy shit! It's Shepard!!" Worth noting is that these Cerberus troops are indoctrinated and partially turned into Husks - they're physically unable to feel fear, and they still panic when Shepard arrives.
Played for Laughs in the Citadel DLC, for a good part of the Normandy crew, when they all rush to the archives to find who is behind the attempted assassinations on Shepard. The CAT6 mercs are terrified of facing the entire team.
CAT6 merc: I think that turian they've got is Archangel! How the hell are we supposed to kill him?! Garrus: *BANG* You're not. —- CAT6 merc: But they've got a krogan! Why don't we have a krogan? Wrex: Wouldn't want to be you, princesses! HAHAHA! —- CAT6 merc: Shit! That's a Prothean over there! Javik: And that's a future corpse over there!
The third game gives us Kalros, the "Mother of All Thresher Maws". While that might be an exaggeration, it's still one of the most powerful creatures in the universe. As Garrus puts it, when the krogan name a Thresher Maw, you know you're in trouble, because that means they don't think it can be killed. It kills a Reaper in single combat.
Everyone from senior Jedi to Mandalorians to Sith are intimidated by the name Revan. When your party hits the Star Forge, Malak panics and sends out every war droid and cannon fodder troops he can muster - not to defeat you, Revan, but just to slow you down while he prepares for a one on one saber brawl.
Likewise, many a flashpoint party in Star Wars: The Old Republic was torn between cheering and panic when they heard the words "Statement: Hello, Meatbags!" Yes, HK-47 is 300 years old. Yes, the droid will still kick your shebs. Imperial players also had this reaction to having to put Revan himself down like a rabid dog after Revan went insane and started planning genocide against anyone with a trace of Sith species ancestry.
Tol Braga: He's more than darkness; he is... a void...
The Aptly-named Dread Masters are the personification of this trope. Six powerful Sith whose combined strength can drive whole fleets mad. They have no compunction to use their powers to terrorize both Friend and Foe. In a way, they even fear themselves; they can only fully control their powers because they had to use the Force to create a sort of Hive Mind, so that they can share the effects of their powers equally between each other. After one of them dies, the Sanity Slippage starts going into full effect.
The Sith Warrior often gets this reaction from others due to the fact that you're more or less treated as a force of nature by your targets. A Light-sided Warrior can occasionally use their reputation to terrify their enemies into submission or retreat rather than killing them.
In Yggdra Unison, most people who are not Bronquian or didn't serve alongside Gulcasa at some point are scared shitless of him—and this reaction is fairly well-deserved. Being Unison, this is Played for Laughs—most notably in how Pamela tries to turn tail and run every time they meet, even when she's the one invading his land.
Hawke in Dragon Age II, to a lesser degree, as the enemies are usually smaller groups that Hawke slaughters before they have a chance to shit themselves, but the Arishok certainly fears Hawke enough that the first move of his attempted conquest of Kirkwall is trying to neutralise him/her. An odd example too, since in Qunari culture fear and respect often go hand in hand.
In the third act, Meredith's dialogue implies that she knows that Merrill and Anders are illegal Mages. Because of their friendship with Hawke however, she states that the only thing protecting them from the Templars is because she knows doing so, would end up bring a wrathful Hawke down upon her head.
In the ending, if sided with the mages, Hawke's Death Glare manages to make Knight-captain Cullen literally jump back, allowing Hawke and Co to casually leave the scene, despite being surrounded by Templars.
The Horsemen of the Apocalypse scare everyone. Heaven, Hell, and even their own superiors fear and respect their terrible power. The entire plot of the game takes place because nobody wants to cross all four of the Horsemen. In-game when Mooks encounter War their reaction is basically a Mass "Oh, Crap!" while they desperately charge you.
Both subverted and played straight in Darksiders II: many NPCs state the only reason they are not running away in fear of being on the same planet as Death is that 95% of his power is sealed.
Bowser of Super Mario Bros. scares everyone in the Mushroom Kingdom who isn't named Mario, Luigi, or Peach. In Super Mario RPG Bowser's presence in the party actually frightens away his former Mooks who have defected to Smithy. Yes, his mooks fear him more than they fear the living weapons factory from beyond the stars. It should be noted that Bowser is always portrayed as a Benevolent Boss, and his mooks are still scared of him.
By the time of Half-Life 2, the feats of GordonFreeman in the first game have been told and retold to such an extent that most of the planet is either in awe of him or intensely fears him, to the point where a mere glimpse of him in City 17 is enough to put the Combine on high alert.
Alma is generally considered to be the most terrifying thing in the game, both in and out of universe. The mere possibility of her being released and what this would mean results in total pants-browning terror to Armacham's personnel, to the point that Genevieve Aristide is willing to effectively detonate a nuclear-scale explosive in the middle of a major city to stop her. Eventually, the Point Man does the same. It doesn't even slow her down.
In the third game, there's The Creep. How bad is he? Alma is afraid of him. ALMA. For a good reason, too. It is the personification of the worst traits of her father, Harlan Wade. It turns out that the only way to stop it is for the Point Man and Fettel to actually destroy their own horrific memories of Harlan Wade when they were children so they can face the Creep and kill it.
By the later parts of the games, the Point Man, Fettel, and Michael Beckett become these to the ATC troops and even the Replica. They know that they can't stop these superpowered soldiers, and that fact scares the piss out of them. In the third game, the Phase Commanders have to order their troops to fight on pain of dismemberment to keep them shooting at Fettel and the Point Man.
Play right and get the right perk(s), and your character can become this for any one (or more) of the warring factions. The easiest group to do this with is the Powder Gangers when you attain the Vilified Status, when one of them refers to you their personal "GrimFuckingReaper."
Joshua Graham was this for the NCR and is now this for the Legion, who speak of him as a vengeful spirit (they're not completely wrong). NCR snipers made no less than 5 attempts on his life, all of which failed despite all of them managing to shoot him and after his failure to take Hoover Dam Caesar had him covered in Pitch, set alight and thrown into the Grand Canyon. Even that wasn't enough to put him down.
Graham's successor Legate Lanius is equally feared as "The Monster of the East", with the Lonesome Road DLC stating that his greatest weapon isn't his skill in combat (though it is indeed formidable), but his carefully cultivated reputation as a mythological figure feared by both his enemies and his own men.
Father Elijah, by virtue of being bat shit insane and the greatest mind the Brotherhood of Steel has ever seen. When he got to Big Mountain he managed to hijack two of the think tank professors (two of the greatest minds of the 21st century in robot jars) and is regarded as their most dangerous criminal. Christine Royce, charged with hunting him down, is more than a little wary of him and tries to keep as much distance between them when trying to kill him. It doesn't work out.
The Think Tank in Old World Blues are not only talked up as terrifying opponents by Dr. Mobius, they are so dreaded that they even scare Ulysses, the Big Bad of all four DLC. In one log, he states that it would take a hundred Elijahs to challenge them. They've got cheat codes, and if you manage to bypass the Pacification Field, they're not actually that tough.
Randall Dean Clark of Honest Hearts was an old Pre-War soldier who became a Crazy Survivalist after entering Zion National Park. He was eventually joined by some Spanish-speaking refugees, and he began secretly providing them aid and supplies. When an expedition from Vault 22 butchered the refugees, Clark began a one-man guerilla war against the expedition. After methodically wiping out two-thirds of the hundred-strong group with traps, explosives and his trusty custom rifle over the course of almost a year, the survivors began to attribute the deaths to an evil spirit which haunted the canyon, and fled in terror, but not before leaving thisApocalyptic Log. Randall eventually took under his wing a group of children whose ancestors would go on to become The Sorrows tribe.
The Institute is widely feared, and suspected of producing synthetic replicas of people and inserting them into settlements to spy on others. The paranoia it sows into the towns of the Commonwealth is so great that close brothers will shoot each other based on the mere suspicion that their brother has been replaced.
Institute Coursers are elite synthetic men whose main job is to assassinate people and recapture escaped synths, in a devilish blend of Terminators and Agents. The first one you encounter will be found wiping out an entire building full of Gunners, their commander panicking over the intercom as they desperately try to stop him. When you reach the Courser itself, you'll find that no, Gameplay and Story Segregation does not apply - if you don't have decent gear and the proper level, you're in for a really tough fight.
Nobody goes near Boston Common for fear of Swan, a hulking Super Mutant Behemoth who sleeps in the lake and wears a swan boat as armour. The area is littered with warning signs and the skeletons of those who failed to heed them. There's even a Railroad sign plastered up that's usually reserved for areas infested with Institute synths. Companions in your company will make nervous comments as you approach. Raiders chasing you will stop their pursuit if you enter, sometimes commenting that they'll let Swan deal with you.
Mannimarco, the King of Worms, is a powerful Lich/Necromancer who has terrorized Tamriel since well before the time the main series of games takes place. He is perhaps second only to some of the more more malevolentDaedric Princes in terms of the dread he inspires as, due to his mastery of The Dark Arts, he can not only kill you, but torture you for eternity with the pain of undeath. He serves as a major villain in Daggerfall and Oblivion, and is The Dragon in The Elder Scrolls Online.
The Dragonborn in Skyrim is one to the Dragons, being a mortal who has all of their powers and the ability to devour their souls. Listen carefully during your first fight with onenote He says, "Dovahkiin? No!" and you can hear it realize who it's dealing with. Considering they cannot be permanently killed by any other "mortal" (and take half-damage from anything that isn't you), it's pretty justified. The soundtrack during Dragon-fights is even titled "The One They Fear".
The CEO/Mob Boss "Drake" in the SNES Shadowrun title. Much of his mystique comes from no one seeing his face. In what will come as a surprise to no one who's played the tabletop game, he's actually a dragon; in a cyberpunk future, their trademark Money Fetish manifests itself by becoming captains of industry.
Downplayed with Valvatorez. He is actually a very nice fellow to be around. Justified in the fact that he REALLY IS powerful enough to warrant that reputation. Infinitely more so in his Tyrant state.
Sepulchure in Artix Entertainment games fits this trope really well. In fact, anyone who isn't the hero or any of his/her allies or even King Alteon himself, or doesn't affilate with the Shadowscythe in any way is afraid of him. Even some of the Pactagonal Knights are scared shitless of him and his flying dracolich fortress of Shadowfall.
Diablo himself; appropriate, given that he's the Lord of Terror.
In Diablo III the Nephalem becomes this for enemy forces. You find a journal from a cultist who is dreading his current assignment of being part of the scout party looking for you. By the end of Reaper of Souls, even Tyrael is a little terrified of you, as you have amassed great power but as a mortal you could potentially turn corrupt and doom all of humanity. Considering that you almost decided that killing Adria out of Revenge Before Reason was worth compromising intel on Malthael's whereabaouts, he's not wrong.
BioShock has Frank Fontaine, the Bronx mobster and smuggler who ran Rapture's underworld and Plasmid market. Among those who knew him, his reputation for ruthlessness was such that half of the city are "still jumping at his shadow" nearly two years after his death has been widely publicized. At one point, the player comes across an audio diary on the electrocuted corpse of a thug who was interrogated for information on Fontaine by Andrew Ryan's men. His response is "Fontaine can do double!" One of his employees Dr. Suchong, however, remarks that although Fontaine "is scary son-of-a-bitch" and has styled himself into the Boogeyman of Rapture, he prefers his employment over that of the "cheap son-of-a-bitch" Ryan. This is in part because he reasons earlier that, underneath all the "flim-flam and humbug", Fontaine is just another con-man. Fontaine's main advantage is that he's in a city of artists and intellectuals, not hardened killers.
Tales of Zestiria and Tales of Berseria have whoever has the Lord of Calamity title, the Big Bad of Zestiria being one and the protagonist of Berseria gaining that title over time; in fact she is the one that the term originates from. A Lord of Calamity is an incredibly powerful hellion/daemon that brings powerful malevolence wherever they go, with the Big Bad of Zestiria showing it off by instantly turning two entire armies into hellions on his first appearance alone; he also is such a Hopeless Boss Fightyou don't even get the chance to fight him with The Hero instantly knocked back and De Powered by one blow. Velvet doesn't quite do that, but she racks up quite the death toll and is responsible for a lot of places being overrun by daemons one way or another thanks to her quest for Revenge and the lengths she's willing to go to succeed at it. Not to mention she kills their "heroic" Shepherd at the end, along with a bunch of other powerful exorcists.
The Spy fulfills this role amongst the enemy team. A lot of the meta-game is about identifying, finding, and killing enemy Spies before they can cause chaos. A common complaint in game? "Man, I hate good spies!"
And then it loops back around due to Spies generally being terrified by Pyros, who are the natural counter to Spies and the usual lot who check for them behind their team's lines. Even fully-cloaked Spies give Pyros a wide berth, as even a split-second puff of flame from a trigger-fingered Pyro who thinks they saw something can make your death a certain thing. "Meet the Pyro" reveals that, in canon, the fear of the Pyro extends to everyone - including his own teammates. He sees a Sugar Bowl where he dances around, sprays rainbows and bubbles around and gives giant lollipops to fat cherubs. His enemies (what the cherubs really are) see a faceless monster who burns anyone he runs into and chops up the survivors with his axe.
Heavy: I fear no man. But that... thing... it scares me. Scout: No, I- I ain't talking about that freak, alright? *beat* He's not here, is she? (panicking now) How do I get this f**kng thing off!? Spy: One shudders to imagine what inhuman thoughts lie behind that mask, what dreams of chronic and sustained cruelty...
Gameplay wise, being in the vicinity of the ghost on the Harvest Halloween event map is enough to make even the most hardened of mercenary scream and lose all will to fight. The Headless Horseless Horsemann also has a similar effect.
Interceptors are this in E.Y.E.: Divine Cybermancy. Though easily destroyed with anti-tank weapons, their tendency to sneak up on players and their extremely powerful battle cannons (enough to kill most unshielded characters instantly) have given many players a well-justified paranoia in any areas they can spawn in.
There are several in RuneScape, but the crown has to go to Nex, whose mere presence terrified the gods enough to make them temporarily band together to seal it away.
This can be invoked by having your levels be high enough - underleveled enemies will flee from you on the map (until they hit a wall at least, at which point you can get a pre-emptive attack if you want).
Lucas gradually becomes regarded as this In-Universe by the villainous Pigmasks. The only one in their ranks to actually impede him was their Commander, the Masked Man; once Lucas overcomes this threat, all of the Pigmasks there to witness it run like hell.
Upon realising that the Ultimate Chimera is the last of the experiments from the Chimera Labs that had not yet been recaptured, a horrible silence falls around the Pigmasks who knew that they'd now have to try to contain it. The player is told several times NOT to engage it if they see it, and for good reason.
Wilhelm is stated to have been able to defeat the Vault Hunters of the first game, with Angel often fearing his intervention. When you finally encounter him, Roland immediately tells you to retreat. Despite this, he's an Anticlimax Boss that goes down easily. There's a reason for this: Jack wanted the Vault Hunters to defeat Wilhelm so they would loot the body, take the unusual power core that he was carrying, and link it to Sanctuary's shield genetators so that he could shut them down. In Borderlands: The Pre-Sequel!, in which Wilhelm is one of the playable characters, his backstory is that he was one of the greatest mercenaries of the galaxy and is a semi-legendary figure to those who recognize him.
Dishonored gives us Corvo Attano, the player by the end of the game. Given that the entire game is his Roaring Rampage of Revenge, this is rather unsurprising. Depending on how you play, the Final Boss may end up killing himself out of sheer fear of what Corvo will do to him. Similarly, Corvo's Evil Counterpart and master assassin Daud is also feared as the "Knife of Dunwall".
Nyarlathotep, the Crawling Chaos has this effect on pretty much anyone around him in Persona 2 whenever he steps out of the shadows with party members noting that their personas are getting frightened. Even the poker-faced Baofu's blood turns to ice when this guy steps forward.
The Reaper in Persona 3. Five words ("Be careful! I sense Death!") are enough to make both the party and the player collectively soil themselves.
Agent Forty-Seven of Hitman fame. If you hire him, you're always buying death - to be delivered swiftly upon your enemy with no evidence left behind. Other killers from the International Contract Agency are Properly Paranoid of 47, which shows best in the few levels of Absolutionwhere they are actively hunting him.
In Hitman (2016), you go after a target who knows your career and appearance. If you show yourself to him in your trademark suit, he dies of a heart attack.
Prince of Persia: Warrior Within: The Dahaka is this to everyone in its path including the player. It cannot be reasoned with, it cannot be stopped, it is terrifying and it will kill you.
Iris Heart in Hyperdimension Neptunia Victory. Everyone - allies included - learns that you only take Plutia lightly once. The mere threat of her activating Super Mode is enough to make major villains rethink a confrontation, lest they require additional months of therapy.
Samus Aran becomes this to the Space Pirates during Metroid Prime trilogy. The pirates start panicking when they see Samus effortlessly storm their bases and defenses and they basically go Oh, Crap! in Echoes when they discover that Samus and her dark copy, Dark Samus, are running around at the same time, killing them. All three of the Prime games have Apocalyptic Logs, and in the ones written by the Space Pirates, she's the apocalypse.
The SA-X serves this role in Metroid: Fusion, and with good reason - for 95% of the game, your only defence against it is hiding and/or running away when it is near. If it spots you, pray that you're able to dodge its attacks or you'll wind up staring at the game over screen very quickly. At the same time, the X realize that the real Samus is such a threat to them that around the midpoint of the game they attempt to blow up the space colony, sacrificing the SA-X in the process, just to kill her.
Medivh from Warcraft. Whether it's because he was possessed by the most powerful Mad God in the setting or because of his own considerable magical power and knowledge (the very reason the Mad God was so eager to possess him), even other powerful beings would give him a wide berth. Gul'dan, Kil'jaeden, and Deathwing all feared Medivh. The only reason Anduin Lothar and his companions were able to kill Medivh was because Medivh had already exhausted most of his power fighting his mother Aegwynn. Decades after his supposed demise Medivh is still considered one of the worst threats to ever appear on Azeroth. When he came back to life to try and make up for some of the damage he had done previously, he had to conceal his identity so people he needed to work with wouldn't run screaming from his presence.
Trevor Phillips in Grand Theft Auto V is one of the most feared characters in the entire franchise, and almost certainly the most feared protagonist. Everyone who knows him, even his friends, speak about him in cautionary tones. Even his former best friend, Michael Townley/DeSanta, is terrified of him and describes him as "Hell walking on Earth."
Tomb Raider (2013): Lara Croft herself becomes this when she gets Tired of Running from the Solarii goons and decides to fight back. Over time, Enemy Chatter both in and out of combat reveals that the mercs are actually scared shitless of her and hope they don't run in to her. They don't even know her name, but they start uniformly referring to her as "The Outsider". Not an outsider. The Outsider.
Ghetsis has become this by the time of Pokemon Black And White 2, when the world at large is aware of who he is, what he's done and what he's willing to do in his quest for power.
The fish-like Pokémon, Wishiwashi, introduced in Pokémon Sun and Moon is described as this towards both humans and other Pokémon. While the individual creature is very weak and tiny, its ability to summon hundreds of other Wishiwashi to create its School Form earned it the title "The Devil of the Sea" among the Alolan people. According to its Pokédex entry, even a Gyarados would flee for its life at the sight of the School Form. There's also Bewear, who is actually rather nice itself, but is a Cuddle Bug who Does Not Know His Own Strength and has killed several trainers through accidental spine-snapping. Warning signs about Bewears in the area are plentiful in Alola.
Before both Ghetsis and Wishiwashi was the nigh-unstoppable, Mewtwo. Oh, Crap! is certainly justified here, for this beast of a Pokémon gave even the great Red a harsh time. It is one of the few Pokémon capable of fluent speech, that and boasting intelligence superior to humans. In the games it's catch-rate is ridiculously low, for it yields only to the most determined of players.
Shu Shirakawa of Super Robot Wars fame has not only achieved this in-game, but has also achieved this on a meta-level with veterans of the game. Whenever he shows up, something bad is going to get worse. And this is before we mention NeoGranzon.
In City of Heroes player characters, both hero and villain, became this over time to enemies, at least reflected in the dialogue. More than a few enemies in missions would declare such statements as "I didn't sign on to fight *character*!" That said, it was also fairly easy for players to make this with their power choices - Dark Armor had a power that generated an aura that caused enemies caught in it to quake in fear, and anyone could get the Presence power pool, which capped off with the power "Invoke Panic". In the early days, enemies hit with Fear would immediately turn tail and run, further reinforcing this image. A high level player could wander into one of the random groups of low-level enemies (outside a mission) and would be ignored due to a game mechanic preventing low-level NPCs from pointlessly killing themselves by attacking players they had no hope of defeating, even en masse. If any one of the enemies was hit by some kind of power, however, the entire group would immediately flee.
Monster Hunter 3 Ultimate has the Deviljho, an Extreme Omnivore monster who starts appearing in High-Rank quests. The Guild Sweetheart warns you the first time you see it in a Moga quest, and in the "Everyone so Big-Big!" video, the hunter, Felyne, Melynx and Cha-Cha at the end all run for their lives as a Deviljho spots them, complete with the series' signature Scare Chord.
In Drakengard 3, Zero is openly feared by the mooks who face her, all of whom generally cower in fear and scream for their mothers as she cuts her way through them.
God of War Series: Kratos is portrayed as being feared by nearly all of Greece, in part due to the various atrocities he committed while serving Ares. In the first game, several people are more scared of him than of the various monsters and beasts, with one person even flat-out telling Kratos to his face that he would rather die than be saved by him. Pandora even says outright in III that everyone who knows about Kratos is scared of him, to which Kratos simply remarks that "there are reasons for that."
[PROTOTYPE 2]: Alex Mercer has become this as of this game, and for good reason considering he's the cause of the Blacklight outbreak. In the game's beginning, Red Crown's reaction upon learning that Alex is in the Red Zone is a very panicked "Oh, shit!"
In Dark Souls I, most enemies are described as powerful, but beatable. The one exception is the Bonus Boss, the Black Dragon Kalameet. He is described as the sole remaining Everlasting Dragon, having survived the war that exterminated his species, and is so vicious that "even mighty Anor Londo dared not provoke his ire". Anor Londo is also known as the "City of the Gods" and was the civilization largely responsible for mass-slaughtering the Everlasting Dragons in the first place. And they are terrified of Kalameet.
Aforementioned vampire, Flandre Scarlet, is feared by main characters, her fellow Scarlet Mansion Cast Herd, even her own sister, who confined her to the mansion's basement in an attempt to protect everything from her. She has power to utterly annihilate anything unfortunate enough to be targeted be her, at one point casually vaporizing a meteor shower, and while she bears no malice to anyone she has poor impulse control.
Oni were exiled from Gensokyo some time ago for causing too much trouble and since largely disappeared, which is good since they're all have immense Super Strength and are absurdly resilient even by youkai standards, and they have a tendency to pick fights with everyone. The return of Suika Ibuki caused much consternation despite her being largely friendly, and it is to everyone's relief that Yuugi Hoshiguma has deigned to stay in Former Hell, given she's rumored to be able to collapse buildings with just her footsteps.
Even more than the oni, there's the satori species whose defining trait is to compulsivelyread mindsout loud. This trait even makes them unwanted among the exiles of Former Hell and made one of them isolate herself in a huge palace in order to escape all prejudice and drove her sister to give herself a Poke in the Third Eye simply because all the fear and hatred of her became too much for her to bear.
In Jurassic Park: The Game, the mysterious predators that harass Nima at the beginning, later revealed to be Troodon, are feared by most other carnivores. During Episode One, Dilophosaurus run away when they hear its cries, and during Episode Two, flocks of Compsognathus flee from them in the Visitor Centre. Even the Velociraptors, the most feared dinosaurs in the broader franchise, won't go anywhere near their nests.
Springtrap, the new animatronic from the third game manages to be this even to the other animatronics.
League of Legends: Every character originating from the Void is one of these, but Rek'Sai is feared even by her fellow void creatures to such an extent that Vel'Koz and even Cho'Gath want nothing to do with her.
Seeing a large enemy army unit, shown as 3 men in a group, approaching your counties on the map, especially if you don't have a castle up yet, and/or your main army is too far to intercept them.
In battles, if the enemy takes up a very good defensive position where their archers can unleash their arrows on your forces while protected by their own forces. Expect to take massive losses if you don't have your own archers.
If the enemy has a large group of crossbowmen. Though they fire much slower than archers, and have a much shorter range, any hit from one of their bolts is guaranteed to make you lose 1 person per shot, even pikemen.
In Undertale there is none other than YOU, if you choose to kill every monster in your path. Eventually you start hitting "empty" Random Encounters and find that all the puzzles have been completed for you by all the monsters that are fleeing in sheer terror of the thing that is sweeping through and slaughtering everything it encounters. Even the final boss Asgore is scared and tries (very unsuccessfully) to talk his way out of a fight.
In the Genocide run, it's Sans. Anybody who has caused enough destruction to invoke his wrath learns to fear him. Flowey states in a post-Neutral conversation that Sans is the only thing that has kept him from reaching Asgore on his No Mercy runs, and he's had to reset multiple times to avoid him; the only time Flowey gets the better of him is in the True Pacifist run by catching him and everyone else off-guard. The Fallen Child, despite being an immoral, emotionless murderer, will express concern only when they have to fight Sans.
In Mark of the Ninja, this isn't just an attribute, it's a primary tactic. When you start, a load of gunmen are invading your clan's hideout, massacring everyone. Levels later, after cutting hundreds of guards to bits, not being scared of you is a bragging right. Not to mention, should any non-elite guard find one of his coworkers hanging by a chain from the ceiling, he will flip. Nix the chain if you're using a certain outfit.
Many players will hesitate to challenge a locked and loaded KV2, even if the KV2 player is a complete dunce, because it's still possible for even a complete dunce to score a direct hit with that 152mm howitzer and launch its unfortunate victim into the next county.
The British FV215b (183). It has more than a few mobility problems, and a Fixed Forward-Facing Weapon that's hindered by that, but if you're ever in front of this thing, no matter what you're driving, you're getting evaporated. Clever players are known to use its Instant Death Wedge to clear out whole squads, as most players will bail out immediately if they're at risk of being in its crosshairs. It's quite appropriately nicknamed the Death Star.
In World of Warships, being on certain maps with a island choke points that obstruct line of sight and restrict movement and knowing that one of the stealthy Japanese destroyers is out there and hasn't been located sends battleship players into a cold sweat with the worry that every time they round an island they could be sailing into a swarm of torpedoes.
The Wither Storm. Not only is everyone afraid of it, even hostile mobs flee from it. Endermen are the only things that aren't afraid of it.
Witches. Even Ivor's afraid of them.
The Doomguy in DOOM has this reputation. He earned it through being a nigh unstoppable force rampaging through hell, killing even the strongest demons in the realm, and was only stopped by being entombed. When he's freed at the start of the game, you can see why. You can find quite a few bits of demonic artwork that portray "the Doom Marine" as an unstoppable evil, as well as UAC reports indicating the demons were freaking out and fighting with more ferocity than ever before seen when the UAC started getting close to recovering the sarcophagus containing Doomguy. His list of titles given by the legions of Hell (who call their realm Doom) include The Doom Slayer, Hell Walker, The Unchained Predator, and The Scourge of Hell.
Star Control: The Dnyarri used to be a race-wide example. Back then, they were a race of toad-like aliens with so much psychic power just one of them could enslave an entire planet, and they always did. They took over an entire race coalition after taking over the aliens that made first contact, and the race that wiped them out at last (by cutting the PSI link through excruciating species-wide pain) has more or less gone insane with fear and usually isolates, or even wipes out other races in an effort never to be enslaved again. Everyone else "just" speaks of them like they were the Devil himself, an embodiment of evil. This fear can be brought back once you find out another race revived one of the Dnyarri, and you can practically see the aforementioned race crapping its nonexistant pants once they find out about just the one Dnyarri.
While the Killers can all count in Dead by Daylight, the Trapper has a skill based entirely on his sheer presence causing fear. This translates to making all survivors within a radius around the Trapper have more Skill Shots when doing anything, increasing the likelihood that they'll screw up.
Usually, the Player Character in the Baldur's Gate series is subject to Dude, Where's My Respect? attitudes and attacks from mooks who are clearly Too Dumb to Live. This changes by Throne of Bhaal, especially in the fight with Sendai. As you're defeating her minions, you're treated to several cutscences where Sendai berates her advisors for not effectively dealing with you. When she finds out who exactly is trashing her base, she immediately freaks out and racks her brain to find any way to stop you.
Fallen London: The Seekers of the Name are by no means an organization, nothing joins them beyond a terrible quest and all the consequences and drawbacks it brings. But everyone, from the lowliest urchin in the streets to the very Masters of the Bazaar, is unnerved by them. And they are right to do so; to the urchin, and most Londoners, Seekers are volatile, prone to extreme acts of self-destruction that they nonetheless survive, perfectly willing to destroy you and everyone you love just for another scrap of knowledge and entirely capable of devouring you if their self-control falters. To the Masters, they are those who carry out Mr Eaten's will, an agenda of terrible vengeance for betraying him so long ago. They know far too much, and their success would ruin them forever. A reckoning will not be postponed indefinitely, not while they are around to make it happen.
The Ace Attorney series gives us Manfred von Karma. The most feared prosecutor in the series who has went forty years without losing a case (until Phoenix defeats him). Manfred is well known for his intimating behavior managing to even get the Judge to obey his every command. Even Edgeworth at the time knows that Manfred is someone not to be trifled with.
We also have Damon Gant from the first game as well. Given his position as the head of the police department, no one dares to speak against him. Not even Chief Prosecutor Lana Skye dared to speak ill of him and even done whatever he said.
Shelly de Killer from the second game (and Investigations 2) is this to a number of people that know of him. He is a professional assassin that knows how to get the job done. Also, you do not want to piss him off and destroy his trust. He will hunt you down until you are dead. The last two known people to hire him did this and were pretty much screwed (and they were both Big Bads!).
Bruto Cadaverini, The Don of a major mafia family. His name is not to be uttered casually, and if he makes you owe him something, you will commit to it, as an otherwise-fearless Loan Shark thug learned the hard way when he got into an accident with Cadaverini's daughter Viola, causing said thug to owe one million dollars to cover her head surgery and work to make that money happen, even if murdering someone else is involved.
Phoenix himself is an odd case, in that he's technically feared but always treated with zero respect in court itself despite his record and the fact he's won against highly respected prosecutors and ended countless winning streaks. Thing is, that's actively part of the reputation, when one combines the infamy for bluffing and struggling with the "Turnabout Terror" reputation he has. Everyone that isn't feeling overconfident (which is many of them) knows that Phoenix's modus operandi is to flounder around helplessly 95% of the time, and suddenly latching on to a single thing and trashing the prosecution's entire case in a matter of minutes before anyone else can do anything, and even if it seems completely certain the Defense's lost. Everyone gets caught up in that initial 95% of relentlessly mocking him, but everyone knows he'll still win.
Then there's EVA-01. If players get Shinji booted off the field, EVA-01 will turn on it's berserk mode, slamming targeted allies not once, but twice in a row with its Second Attack.
Injustice 2: just like in the comics, Brainiac is one of the most dangerous villains in the universe, one that Superman and Supergirl both fear, with Supergirl witnessing the destruction of Krypton by Brainiac firsthand and Superman believing there's no way he can even be defeated.
The Legend of Zelda: Breath of the Wild has the Guardians and Lynels. The Guardians are notorious for their role in destroying the Kingdom of Hyrule a century ago, and NPCs universally flee in terror from them even if they are the types who would stand their ground against other monsters. Lynels are described by the Hyrule Compendium as the most vicious of all the monsters roaming Hyrule, and one Zora character even tasks Link with taking a picture of one living on top of a mountain to discourage people from diving from its summit (and she herself screams when you show her the picture). Even Prince Sidon, a boisterous Warrior Prince who once took down a Giant Octorok and is cheerily eager to help Link fight against Divine Beast Vah Ruta, has an Oh, Crap! moment upon realizing that Link will have to sneak past that same Lynel to gather Shock Arrows for the fight against Vah Ruta.
In The Legend of Heroes: Trails of Cold Steel II, as far as Calvard is concerned, the Ashen Chevalier is their greatest threat. Anytime he enters the battlefield, they retreat right away after the pilot one-shots both their planes in one attack. And the identity of that individual is Rean, who is also not happy about the entire "national hero" job thing.
Johnny Gat of the Saints Row franchise. He may be The Lancer/The Dragon to The Boss, but it's widely known he's more feared and avoided. Such a fear-inducing badass he is, that Big Bad of Saints Row Iv, Zinyak, abducts him a full game in advance because even he feared Gat would be trouble.
Brigador includes the concept as a game mechanic. More dreaded mercenaries get more money, because their employers are willing to shell out more cash for them than for nobodies, but they also face heavier opposition because their enemies are willing to pull out the stops to kill them.
Middle-earth: Shadow of Mordor and its sequel Middle-earth: Shadow of War have the protagonist Talion. By the end of the first game, orcs are talking about him like he's the boogeyman, and you can see why — he slaughters enemy armies singlehandedly, he can effortlessly brainwash orcs to his side, and killing him only slows him down. This gets to the point where one possible trait for enemy captains is "Fear of the Gravewalker", which makes them shit their pants and run screaming in the other direction in reaction to your mere presence.
Nocturne: Rebirth deconstructs this with Hypnosis and Reviel, who are both known for mass murder. Hypnosis is the more infamous of the two, but only because there are tales of a hero defeating him, making him paradoxically feared and a Butt-Monkey. On the other hand, Reviel is less infamous because no hero has ever defeated him and because there are no survivors to recognize his face. As a result, people eventually forgot about Reviel despite his greater threat level, allowing him to blend into human society easily.
Treasure Planet: Battle at Procyon: The appropriately named 'Dreadnought', the Dreadnought is the largest Ironclad and is the most technologically advanced and powerful ship in the game, the Dreadnought's armour is so thick, lighter projectiles will almost always bounch off harmlessly and even heavier projectiles have their damage reduced, the Dreadnought is also one of the most heavily armed ships in the game. The manual states that almost nothing is known about the Dreadnought as no ship has ever survived a close encounter with one. The fact that they tend to have names like 'Terror', 'Devastation' and 'Obliteration' doesn't help either.
