History YMMV / PokemonSuperMysteryDungeon

--> '''Carracosta''': Don't let your dreams just be dreams.

--> '''Cleffa''': I like shooting...

* DemonicSpiders: In previous installments of the Pokemon Mystery Dungeon series, Ditto would simply appear as mimics of other Pokemon when you encounter them in a dungeon, making them little different from standard encounters. Come ''Super Mystery Dungeon'', however, Ditto now appear to be [[ChestMonster perfectly normal items until picked up]], whereupon they transform into the unwary adventurer ''and confuse all of its teammates''. Your first encounter with them comes in a dungeon with a guest character who is at least twice your level. If you don't have a way of eliminating a copy of yourself quickly, chances are good that you'll be knocked out by your own teammates' wildly thrown attacks. The cherry on top? They can be [[ParanoiaFuel any item]], and there's no way to detect them beforehand, even with Emera that sense objects and enemies, or by attacking items first.

* NightmareFuel:
** [[spoiler:Dark Matter]] itself. The thing looks like something between a cross of the ''Persona 2'' Nyarlathotep and the Shadow Selves from ''Persona 4'', and it's in fact so strong that it can outright TURN EVERY LIVING POKEMON in the world to stone...including Mega Evolutions, normal Legendaries such as Entei, Latias and Moltres, Mythicals such as Deoxys and even '''THE VERY GOD OF THE POKEMON WORLD ITSELF ARCEUS.''' (!!) Nothing in any Pokemon game goes anywhere close to this ''thing''; It's almost like it's not even supposed to be here, lest be any Pokemon game.

* PlayerPunch: When your partner asks you if he/she can be annoying after the field trip into the School Forest, and you say yes (You can have perfectly valid reasons for saying so), their dialogue in response '''WILL''' make you feel like a complete jerk.

*** Around that same time you can also do a fairly easy mission for Whiscash that nets you Alakazam, Tyranitar and Charizard. While Charizard isn't over level 50 like the others it can be re-taught Heat wave to make it a powerful room clearer early in the game. And while it can be difficult a mission for Flygon can net you not only another powerful room clearer but also a level 64 Hydreigon with incredibly high stats and a solid movepool.

* ScrappyMechanic: The cooldown period that higher-level Pokemon sometimes go through after going on an expedition. This was implemented due to the fact that the player recruits many high-level Pokemon even in the early parts of the game, and seems to be aiming to keep the player from [[ComplacentGamingSyndrome settling on a single team and never trying any other Pokemon out]]. However, since the cooldown seems to occur at random, and even happens to Pokemon that you haven't taken on an expedition recently, the mechanic is utterly reviled, to the point where some players stop playing the story mode and stick to playing on Pelipper Island once they've recruited the team they want.

** Mystery Jungle, a solo dungeon that comes in the post-game, is even worse, especially for a water-type player. It's filled with Venomoth (who can power themselves up with Quiver Dance and then wipe you from a room away with Silver Wind), Ariados (who can use Bug Bite to eat your Reviver Seeds and Oran Berries) and Trubbish (who leave Toxic Spike traps laying around everywhere). Worst of all, however, are the Haunter and Gloom, who can hypnotize, paralyze, puppet, and flinch you. If you're unlucky, and run into a Haunter that just feels like spamming Hypnosis, or a Gloom that decides to keep you both Paralyzed and Poisoned at the same time, you can die literally without ever getting the chance to fight back.

It's filled with Venomoth (who can power themselves up with Quiver Dance and then wipe you from a room away with Silver Wind), Ariados (who can use Bug Bite to eat your Reviver Seeds and Oran Berries) and Trubbish (who leave Toxic Spike traps laying around everywhere).

* ThatOneLevel: The Submerged Cave contains several powerful Water types that can easily be DemonicSpiders (Barbaracle can use Shell Smash and Ancient Power to boost its stats to insane levels, Seadra loves to spam Hydro Pump, and [[LethalJokeCharacter Lumineon of all things]] can attack twice in rain with Swift Swim), with frequent Rain to make them even stronger. And it's even worse if you or your partner are Fire types...

** Many fans wished the other school children; Deerling, Pancham, Shelmet and Goomy had as much of a big role in the game as Espurr.

** Dark Matter itself. The thing looks like something between a cross of the ''Persona 2'' Nyarlathotep and the Shadow Selves from ''Persona 4'', and it's in fact so strong that it can outright TURN EVERY LIVING POKEMON in the world to stone...including Mega Evolutions, normal Legendaries such as Entei, Latias and Moltres, Mythicals such as Deoxys and even '''THE VERY GOD OF THE POKEMON WORLD ITSELF ARCEUS.''' (!!) Nothing in any Pokemon game goes anywhere close to this ''thing''; It's almost like it's not even supposed to be here, lest be any Pokemon game.

** The use of TakenForGranite as a child-friendly replacement for death has been around since ''Anime/PokemonTheFirstMovie'', and this is not the only Yveltal to use it, but it becomes particularly strained here. Once the plot adds [[spoiler:"[[FireAndBrimstoneHell the place you go to after you are turned to stone]]", [[LikeABadassOutOfHell the ability to fight your way out of being turned to stone]], and a mysterious place where [[DeaderThanDead if you are turned to stone, you are turned to stone forever]]]]...

* ItWasHisSled: Good God [[SubvertedTrope subverted]] to [[TearJerker heartbreaking effects]]. As anyone who played the other games in the series knows, the protagonist always has to return to his own world at the end of the game. The protagonist even [[LampshadeHanging lampshades the probability of this happening]] [[spoiler: after Dark Matter is defeated]]. However... [[spoiler: The protagonist ''isn't'' forcefully torn from the world this time. Instead, ''the partner'' is one who has to disappear into the light this time, being the reincarnation of Mew and thus needs to sacrafice themselves in order for him to return to his normal form. As many players will attest, being on the other side for a change is just as tear inducing as the normal endings.]]
** In itself, [[spoiler: the fact that the partner is the reincarnation of Mew]] has become well-known.

* EnsembleDarkhorse: If fanart is anything to go by, the Japanese seem to be enamored with Nuzleaf.

* CounterpartComparison: The FinalBoss, [[spoiler: Dark Matter]], tends to get a lot of comparisons to the FinalBoss of ''VideoGame/{{Undertale}}'''s neutral and good endings. Both are {{Eldritch Abomination}}s of incredible power who [[spoiler: more or less kill all the beings in their world and attempt to bring about TheEndOfTheWorldAsWeKnowIt because of feelings of malice]]. Similarly, they're both eventually "beaten" by [[spoiler: a character (the partner in SMD, the main character in ''VideoGame/{{Undertale}}'') accepting them, which leads to them to eventually making the right choice and saving everyone. They both are also far more sympathic than they appear on the surface.]]

** The Water Looplet. This equipment allows you to throw an item and have its effects hit multiple targets as it passes thru them. The obvious benefit of being able to disable multiple enemies with Sleep or Allure Seeds. This looplet also prevents enemies from catching the thrown items, making the various spike items a very useful and reliable source of typeless ranged damage. What's more, you can effectively double the value of beneficial items as well, including ''[[RareCandy stat boosters]]'', by having a 3rd character throw them at two other party memebers. As mentioned above, abusing the vitamins to stat grind will turn a pokemon into a unstoppable juggernaught, and doubling this tricks means ''doubling the potential game breakage''. And with proper planning, you can get this tresure as early as ''Chapter 12'', just in time for the [[DifficulySpike Entei arc]].

** Unlike the main series games, there is no 'Effort Value' mechanic in the Mystery Dungeon series. This means [[RareCandy vitamins, Life Seeds, and Sitrus Berries]] will keep boosting a stat well up to the 255 hardcap (500 for HP) instead of only boosting it ten times. These items are surprisingly common drops from treasure boxes dropped from enemies in late game dungeons. Additionally, the vitamins can be bought for a single Gold Bar in towns, and you will acquire a lot of Gold Bars over time as you open chests and as your expedition rank goes up. With enough stat pumping, you can easily turn your starters (or anyone really) into a mini-Arceus that can easily one shot everything the postgame throws at you as they futilely attempt to [[DeathByAThousandCuts love tap]] you.

** Unlike the main series games, stat boosting items can be used until a certain stat reaches its maximum cap instead of only boosting a stat ten times. All the stat boosting items can be gotten for one Gold Bar, and you get a lot of Gold Bars each time your expedition rank goes up. As a result, if you choose to focus on one stat, [[https://miiverse.nintendo.net/posts/AYMHAAACAAADVHk2YJ6eJw the stat growth can]] [[https://miiverse.nintendo.net/posts/AYMHAAACAAADVHk2y8qaXw get a tad bit crazy]].

* MagnificentBastard: Granted, they are a lot nicer than most examples, but both Ampharos [[spoiler: and ''Espurr'']] can play one wicked game of XanatosSpeedChess. It was mainly them managing to stay one step ahead of [[spoiler: Nuzleaf, who in himself is a pretty good contender for this trope]] that the main duo even had a chance of saving the world. Ampharos is also the one who [[spoiler: cooks up the plan to bring the partner back to life behind the protagonist back, since his genuine reaction was needed in order for it to work]], which it ''does''.

* [[spoiler: Instead of you leaving the Pokemon world back to the human world, your ''partner'' has to leave because they absorbed the Dark Matter in the final boss. Your player character in game is even mourning them, crying on their hands and knees throughout the credits.]]

** The aforementioned level 50 Salamence, if you fight it as early as you're able to. It's intented to be more in line of a PuzzleBoss, meant to be knocked out with Blast Seeds, but even then its sheer power and high HP makes things difficult (requiring around 4 Blast Seeds if you throw them, or 2 if you eat them, putting yourself in danger of being mauled by Salamence's attacks). Be prepared to waste a lot of Reviver Seeds.

* ThatOneBoss: The aforementioned level 50 Salamence, if you fight it as early as you're able to. Your attacks will barely do more than 10 damage, while all of its attacks will one-hit-KO you. Be prepared to waste a lot of Reviver Seeds.
