* AnticlimaxBoss: Ceadeus, to most. While its attacks are fairly damaging and difficult to dodge if you're close to it, especially without the Lagiacrus armor, you pretty much can't fail against it unless you faint three times. Upon hitting the seemingly narrow time limit of 30 minutes, it flees and you get some materials. You are then free to take the quest over and over until you've completely whittled down its health.
** Same can be said about Fatalis, Akantor and Ukanlos. Once you learn their patterns, they become ''a lot'' easier. They still hurt you a ton if you're not careful.
** The two kings of this trope are probably Lao Shan Lung and Yamatsukami, both of whom are even more predictable than the above. Lao doesn't even have a move that targets players on the ground, whilst virtually every one of Yama's attacks is clearly telegraphed and easily avoidable even if you have the reaction time of a dead cow.
** The Ivory Lagiacrus in Tri Ultimate is hyped up pretty heavily in game, [[spoiler: being the monster that eventually forced the Village Chief into retirement from his hunting career and all]], and is also the last fight before the credits sequence. In practice, however, it's a slightly stronger Lagiacrus who has roughly the same (or, in some occasions, less) health as most of the fights leading up to it, fights nearly entirely on land (generally considered to be easier than fighting them in water), and whose only real additional threats compared to the normal Lagaicrus are slightly wider hitboxes on its electric attacks and slightly increased damage.
** Barring monsters with dodgy hitboxes or unstable animations, any fight can be mastered due to each beast's well defined behavior. Unfortunately even in offline mode most players will ''have'' to run them until they become easy if they want to craft good equipment.
* CultClassic: A strange example because even though in Japan these games are easily considered a KillerApp and very popular, internationally, it is much less popular overall but the fandom of it still very much love the games. This is one of the main reasons that half of the games [[NoExportForYou are not released outside Japan]].
* EightPointEight: [[WebAnimation/ZeroPunctuation Yahtzee's review]] of ''Tri'' sparked an edit war on the ZP Dethroning Moment page and a Hiroshima's worth of backdraft across the internet.
** Things got worse when he talked about the game in his "Extra Punctuation" column the following week, in which he announced that he had stopped after the Great Jaggi fight. Said fight is occasionally considered by the community to be the unofficial end of ''the tutorial for Tri'', which certainly did not reflect well on him in their eyes.
* FanDumb: Need help taking a certain hunt? To most veterans you're the scourge of the earth and you don't deserve to play it. Some people also get ''very'' opinionated about certain weapon classes.
* GameBreaker: Hammers in Tri, attack twice then windup charge, then attack immediately after you go into charge mode; then repeat, you attack as fast as Sword and Shield.
** The Slime element introduced in ''Monster Hunter 3 Ultimate'', which throws the balance of the game out the window, making the other elements obsolete. The Kelbi Bow, with the Awaken skill which unlocks its Slime element, is becoming infamous because of this, thanks to its level 1 charge spreadshot (5 shots), allowing it to inflict the Slime element quickly and easily ForMassiveDamage. ''And that's before you apply bonuses from Bomber skill''. Granted, monsters will gradually increase their resistance against Slime elements (like any other status attacks), and farming Brachydios [[{{Understatement}} is not easy]], but Slime's utility is so huge that it pales other elements in comparison.
* GoddamnBats: Quite a few of them. "STUPID VESPOIDS!" and "STUPID BULLFANGOS!" is practically a catch phrase to some hunters.
** Maybe subjective, but just about EVERY non-boss (read: not the quest target) monster is a [[GoddamnBats god damned bat]]. Doubly so if you're using a long-range weapon, which tend to rarely be able to kill them in one hit - important when you've got a giant wyvern breathing fire down your pants.
** Tri adds Goddamned Rhenoplos to the mix. Basically they're a mashup of a Bullfango and an Apceros - they share the Bullfango's love for charging but knock you even further, and they have health about equivalent to an Apceros. Add in armored craniums that can deflect frontal attacks of even green sharpness and you've got one annoying enemy.
** For that matter, Tri also adds Bnahabras, souped up Vespoids. You have not known true annoyance until you've seen one sneak up behind you while you're fighting a wyvern, poke you ''once'', and leave you twitching on the ground, paralyzed.
* HellIsThatNoise: Some wyverns can produce utterly otherworldly roars, take Diablos, Khezu or Gigginox, for example.
** The Leviathan Nibelsnarf, despite its UnfortunateName, probably takes the cake. Its roar sound less like a roar and more like ''grating metal''. That it comes from a mouth that has MoreTeethThanTheOsmondFamily doesn't help.
* InternetBackdraft When news that ''Monster Hunter Tri'' was going to be a Wii-exclusive, the 360 and PS3 fans did not take it well.
** When fans found out that not only is the UpdatedRerelease of Tri exclusive to the Nintendo3DS, but the upcoming sequel as well, fans weren't amused.
** In a less {{Console Wars}}-based example, the fact that the 3DS version of ''Monster Hunter 3 Ultimate'' has no online multiplayer, being limited to local multiplayer, made some people bitter, especially considering that ''Monster Hunter 4'', which will be released on the 3DS too, will offer online multiplayer. The Wii U version of the game will allow online multiplayer, though.
* LesYay: The female owner of the item shop in Tri REALLY likes hunters, even if you choose to play as a female. At one point she will even crack a joke about accepting a lock of your hair for an expensive item.
* MemeticMutation:
** [[http://www.youtube.com/watch?v=nSq0GEqtnJI GOTCHA BITCH!]]
** Don't get hit! HIT IT UNTIL IT DIES!
** NIBELSNARF
** [[GIJoe G.I. 'Jho.]]
* NeedsMoreLove: This series might be a huge success in America like it is in Japan if more people [[NoExportForYou actually knew about it]].
* {{Squick}}: The most common reaction to Khezu and his cousin Gigginox. Even the Japanese title of Gigginox translates to "creepy".
* ThatOneBoss: Varies, but Tigrex for most. Very fast, massive range, massive damage. These all increase in Rage mode. Compared to other bosses leading up to it, Tigrex represents a massive spike in the difficulty. Portable 3rd gives us a Black Tigrex which is basically an even faster and stronger version of the original. Another frequent candidate is Rathalos, especially from Tri onward since he spends much more time flying ''just'' out of reach for most bladed weapons.
** Also in Unite, the Nargacuga. A souped-up Tigrex ''who can shoot tail spikes''. Or worse, a Tail Slam that can send you back to the camp in one hit.
*** Green Narga from P3rd is able to do said Tail Slam TWICE in a row. Its spikes will now paralyze you.
*** And 3 Ultimate gives us a rare species of Nargacuga, which can turn ''invisible'' during the fight, and its spikes are now poisonous ''and'' can shoot them ''anytime'' after it uses its tail for an attack.
** Also, [[DoesThisRemindYouOfAnything Khezu]]. It lulls you into a false sense of security with its slow movements and easily telegraphed attack patterns, but its got a metric fuckton of health, is ridiculously resistant to damage (don't bother trying to attack it unless your weapon's sharpness is in the green), and once you finally ''do'' get its health low, it busts out the most devastating [[TurnsRed enraged mode]] you've seen up to this point, utilizing a new lightning charge attack that can easily OneHitKO you and its attacks become ''much'' more quick and unpredictable. Made so much worse when fighting it near Snowy Mountain's ledges.
** [[TheComputerIsACheatingBastard Plesioth]]... [[HitboxDissonance How exactly can smashing me with your RIGHT hip hit me when I'm on your left? Or how can you hit me with your tail when it's ten feet in the air?]] Plesioth has managed to do both of these things and more.
** [[CowardlyLion White Monoblos]]. Not the normal one. The White one. Why? He has more health than his cousin, and he runs away every 5 freaking minutes. Also, he hides in the ground every 10 seconds, rendering him invincible unless you carry the maximum number of Sonic Bombs, which is 10. And it's not enough. Best thing? With the best Sharpness you could afford at first, the only part you could attack properly was his tail and his horn... ''[[MadeOfPlasticine both of which snap off after only a few hits.]]''
** Rajang. Has all the elements of speed and unpredictability of a Blangonga, the roar knocks you away, and it fires LIGHTNING BEAMS and THUNDER BALLS (both are actually non-elemental) from the mouth. Once it's enraged and becomes [[Manga/{{Dragonball}} Super-Saiyan]]... Well good luck not to be hit by its attacks or risk One-hit KO. Unite gives us a type of Rajang that is ALWAYS IN RAGE MODE, and another rage mode upon that (though actually slower). Worse, the best Thunder-element weapons (to deal with Tigrex, for example) can only be made with some Rajang materials...
*** If you're playing MH Frontier then god bless you won't meet [[http://www.youtube.com/watch?v=PN24STb8hEw a Rajang with red aura.]] [[http://www.youtube.com/watch?v=icwb279vbQc Suddenly the normal Rajang (or any other monster) looks pale in comparison.]] INSANE speed, hitbox and attack power that simply murders the whole party in no time. It's [[HarderThanHard so bad, so hard]] that during a period when an exclusive quest was available to those HR/SR 999 hunters hunting this particular beast (with every quest's data recorded officially), the overall success rate is ''5.8%''. No, not 58%. ''Out of 270,000+ tries''.
** The lesser mentioned One-Horned Diablos. It looks like any other Diablos, just slightly bigger and with a broken horn but it's actually a rank above what you're capable of fighting when you can first battle it, which means it hits ''a lot'' harder and has ''[[WhyWontYouDie a lot]]'' more hp and, of course, the game doesn't give you any kind of warning as to what you're in for. You also get the usual items and only a slightly higher reward for defeating it.
** Tri gives us [[DeathFromAbove Rathalos]] (which has been turned from a nonissue in Unite into a genuine ThatOneBoss thanks to a combination of newfound speed and maneuverability and harder access to weapons fit for fighting him) and [[LightningBruiser Barioth]], who is basically Nargacuga but stronger, and who exchanges the ability to shoot tail spikes for being able to ''[[BlowYouAway spit twisters at you]]''. Twisters that ''[[KillItWithIce freeze you solid]]''.
*** Rathalos and Barioth are especially frustrating because of the low availability of fire and dragon weapons early on. Rathalos goes down rather quickly with an upgraded Rusted Weapon with the Dragon element, which can be mined at a very low chance from the Volcano. Barioth is much easier to deal with with a good fire damage dealing weapon. The catch? Most fire-based weapons require Rathalos parts and upgrading a Rusted Weapon requires Frost Sacs from Barioth. Pick your poison.
** Chameleos. Probably the most ''irritating'' enemy in the series simply because it is ''invisible'' for maybe 90% of the time you fight it. It also tends to go back into stealth within 10 seconds of bringing it out of stealth and, all in all, a huge pain in a the ass.
** Go online and try to engage a high-rank Qurupeco. It can summon the Great Jaggi, or the Rathian. It can also summon ''[[NamesToRunAwayFromReallyFast Deviljho]]'', who is just as bad as he sounds. Many a Qurupeco quest has ended because it summoned G.I. Jho.
*** Just like Capcom to not know that everyone hates Deviljho, in 3 Ultimate we got a unique Deviljho roaming around in normal quests... And it's ''always in rage mode''. Want to run away from that? You HAVE to farm them because they contain a unique type of carve to make good stuff with. Have fun.
** Portable 3rd gives us a new monster: Zinogre, which looks easy in its normal state, until it starts to charge up 3 times... And it goes into Hyper Electrified mode. Basically speaking, it IS its rage mode which will not stop until you make it fall down, which means it can stay in this form much longer than others' rage mode. In this state its speed and power rockets to crazy levels, has attacks to make you more vulnerable to thunder-element attacks and fainting, and has a ridiculous hitbox for its attacks. Oh and the paralyzing trap you were using all along? It's IMMUNE to that in that state, and at other times the trap WILL help it to charge up. Also, it can go into rage mode... while already in this mode. Which makes it a [[UpToEleven Double Rage Mode]], something unique in the series.
*** 3 Ultimate gives us subspecies of Zinogre, which can rain down dragon-element thunderbolts while charging up, and is able to launch ''homing'' thunder balls at you. And they're fast.
** A new contender of ThatOneBoss arrives in 3 Ultimate: Brachydios, which also known as "the most powerful package monster" ''throughout the series'', fans and developers alike. Given that Tigrex was so feared even among veteran hunters, this should tell you something. It's very fast and agile, its punch (yes, it's arms are developed enough for this) will leave what amounts to green napalm on you, and if you don't roll for a while to rub it off, the slime will explode and do huge damage; said slime will also explode if you're being hit by Brachydios' attacks. And unlike its fellow wyverns, Brachydios actually uses a different moveset from others like Deviljho (despite being identified as the same wyvern family), it takes some time for even old hunters to avoid being hit, such as its jump attack which lead to deaths of many hunters. Once it goes berserk it'll start using wide-area explosions, doing attack combos along with its increased speed. Inexperienced hunters are actually adviced to ''run away'' instead of attacking it. Of course, beating it will allow you to create [[AwesomeYetPractical new weapons with a Slime element]], making other fights considerably easier, if only one can consistently beat this monster, that is.
* ThatOneAttack: Almost every monster has at least one, if not more. Some examples:
** Khezu: Roar during rage and either a thunder tackle or thunder ball shot. Roar will incapacitate you unless you defend or have High Earplugs. Either scenario inevitably results in a KO in solo.
*** The main problem with Khezu is that they are unique in having no eyes, so they can't technically see you and thus give you the "spotted" status, and you can only do panic dives (that render you invincible; which regular dodge rolls don't do) in this state. Dodging its attacks at the last second is a no-go as a result.
** Gravios: Roar and heat beam. Same as above. High and G-rank one-up this and give the Gravios' a ''sweeping'' heat beam.
** Plesioth: Hip-check. HUGE range, fast and with an [[HitboxDissonance absurd hit-box]] (as in, no part of the Plesioth can touch you and you will ''still'' get hit).
** Rathalos: High-dive claw attack. Comes almost out of nowhere to the inattentive player and is just as impossibly hard to dodge. Fortunately, a running dive can evade it (you need to see it aiming itself at you first, though, which is the big problem) or you can block it (yes, even with the Sword and Shield!). Failure means you will be poisoned and stunned - on top of the huge damage!
*** There is also a sudden fire attack it will do when it suddenly flaps its wings and shoots a burst of flame at you. There is absolutely no warning, blocking it is difficult and it inflicts Fireblight, which can be just as bad as poison.
** The Deviljho's breath attack (Inflicts huge damage and Dragonblight).
** Pearl Espinas: The Firestorm. It essentially flies up and nukes the battle area, spreading unblockable, ''poisonous'' flames around it. Get hit by that, and you have a few seconds before it sends out a shock wave clearing everything around it. And it's the main attack this thing uses. Made worse by the fact that making it flinch during the few second gap where it's preparing to jump is the only way to get a much-needed item from it.
** Nargacuga's Tail Slam. It's basically a close range, spammable [[OneHitKill One Hit kill]] that can be frustratingly hard to roll through and has a kinda iffy hitbox (you take full damage even if you touch the dust cloud it raises after the tail touches the ground). Granted, you can see it coming from a mile away (he roars very noticeably before doing it), but not even Evade+2 can bypass it.
** Qurupeco's monster calls. If you don't have dung bombs, this turns a one-on-one fight with a relatively easy monster into a two-on-one with anything from the relatively easy to manage Great Jaggi or Rhenoplos to the crap-your-pants scary Rathalos, Diablos or Deviljho. It can then boost their attack, defense and even heal them with other calls, as well as itself.
** Uragaan's mighty seismic chin can count if you aren't watchful. It will blow up any rocks thrown by its tail swing, meaning that if you didn't pay attention you have a chance of flying through the air right now, and it's actual damage and flinch radius are questionable until you've faced it enough. Note that the flinch radius will force you to put away your weapon, meaning that you have to draw it again and it just ruined any charge you had going.\\
\\
Also the roar, while not annoying, is followed directly by an attack in front, meaning that you need a certain skill or you have no way of avoiding it if you were in front.
** Brachydios's [[InASingleBound leap slam]], especially when enraged. It does a LOT of damage, is difficult to evade, has a wide area of effect when in rage mode, causes Slimeblight, and usually comes out of nowhere as the tell happens only a split second before it goes airborne. And sometimes it skips the tell and jumps without warning.
* ThatOneLevel: Lance Training Rajang for a Sword Saint Piercing.
* UnfortunateImplications: The black furred felynes are the only ones who are outright hostile and attempt to steal your stuff all the time, while the white furred felynes are pretty nice until someone smacks one. However, there's also friendly "black furred Felyne"/Melynx in villages and cities.\\
By the same logic, you could said that all light colored felynes are ready to snap and blow themselves along with you at the slightest provocation, even if you're not the ones who provoked them in the first place.
* {{Waggle}}: One of the more heavily criticized changes in ''Tri'', despite the inclusion of a more conventional control scheme.
* {{Woolseyism}}: The subspecies of a monster in the Japanese versions usually just has subspecies in its name, but the localizations add colors to their names in order to make them more unique.
