History YMMV / MapleStory

** [[MadScientist Gelimer]] of the Black Wings stands out among the non-commander antagonists as a testament to low the Black Wings are capable of going; while originally a possible WellIntentionedExtremist, he created a gas that would render whoever was exposed to it dead or a puppet of his to control, and fell down the slippery slope until he was recruited by Orchid. He proceeded to kidnap and robotize Xenon, an innocent child, and possibly Beryl, created at least one ManchurianAgent out of his human test experiments, and turns against Orchid by [[PoweredByAForsakenChild using her brother, Lotus, to pilot a warship that would drop the gas he created all over the Maple World.]] Gelimer's complete lack of empathy and desire for a world without human emotion is portrayed as chillingly humorless compared to the other antagonists in the game, and he's serious about completing his ambition, no matter how many people have to suffer for it.

* CompleteMonster: [[ChronicBackstabbingDisorder Magnus the Betrayer]] is the power-hungry, megalomanical antagonist of the Nova storylines. Exiled years ago for abusing his powers, he sided with the ArchEnemy of the Nova race and carried out an attack on Heliseum, killing many, including Cadena's family. His actions eventually required the previous Kaiser to step in, ending with him performing an unsuccessful HeroicSacrifice, Magnus then taking the Nova's capital as well as their champion and protector in one fell swoop. He's shown to absolutely revel in his actions, taking pride in being a mass murderer and double-crosser, joining two different forces wishing to destroy the world [[DragonWithAnAgenda only to gain abilities to cause more destruction in his path]]. Feared by the Nova, reviled by Kaiser and Angelic Buster, and hated by the Black Mage's commanders, Magnus never bothers showing any remorse or sympathy to whom he affects, and he enjoys every second of it.

* TierInducedScrappy: Jett has run of the mill stats (alongside a mechanic of ''re-configuring them randomly'' with a randomly dropped item), "okay" skills, absolutely ''piddling'' damage output (making her a worse DeathByAThousandCuts situation than ''Mercedes''), relies [[CriticalHitClass entirely on critical rate]], and is a GlassCannon, giving her the moniker of possibly the worst class in the game even after multiple re-balances. She briefly got a surge of activity after the Override update, though... because there was a [[GoodBadBugs bug]] that gave her a zero cool-down on a map-wide attack. Once it was patched, Jetts faded out of the game once again.

*** So is Luminous reliable or does his origins split form the Black Mage coupled with his corrupted state make him an extreme liability that could betray the others at any minute? In his fight with Phantom, rather then a simple defend and subdue tactic, he tries to cut the man's head right off.

* MemeticMutation: @@@@@@[[labelnote:Explanation]]Players who sell items will often raise their messages by padding their chat bubble with a lot of @'s (the widest possible character).[[/labelnote]]

** Intercontinental travel. First, you had to buy an expensive ticket. Then, you had to wait for a ship to arrive. Then, wait several more minutes to travel to its destination. Tickets were later made free, and the option to rent a plane (which is much faster than the ships) was added.

** For a while, there was a group of people who would insult you for not following a specific build. If you didn't roll perfect stats at creation and stuck with it, or invested in skills that they don't recommend, they called you a bad player. The stats bit has lessened since the game gives you "perfect" stats automatically upon creation and you can choose to let the game auto-distribute your stats now, but they're still out there.

* Pink Bean is this ''[[LethalJokeCharacter on purpose]]'' with immensely high damage percentages even on his starting skills, Pink Bean can decimate even major bosses that would require extremely high end gear for normal characters without much sweat.

* SuspiciouslySimilarSong: ''[[http://www.youtube.com/watch?v=wJO4ctKnPWA Battlefield]]'', the tune that plays in the Showa hideout sounds a lot like ''[[http://www.youtube.com/watch?v=JsvwYU9K504 Battle Without Honor Or Humanity]]'' from ''Film/KillBill''.

** Will in Zero's story is pitifully easy due to Zero's likely enormous damage range at that point and contributes to the NoEnding.

* AntiClimaxBoss: Players who completed the first two quests of the Madhouse Halloween Event - a dungeon with [[RandomNumberGod so much luck involved]] that Nexon had to install a patch halfway through to prevent bad luck from rendering a player unable to progress at all due to having no Batteries and entering a room without any - was probably expecting the BossBattle at the end to be a climatic fight unlike any the Maple World had ever seen. Unfortunately, [[spoiler:Sean]] is actually not much harder than [[KingMook Dr. Cosi]] was in terms of actual power, and really wouldn't have presented a challenge to a prepared player who had made it that far. (Possibly the whole point, seeing as [[spoiler:she]] had always attacked by ambush in the dark before, a face-to-face fight may have been an AchillesHeel.)

* EvilIsSexy: Hilla wears bare minimum clothing and Orchid is dressed in an evil black uniform that borders on being a fetish outfit. Carta The Sea Witch also shows this in spades, not being so much evil as apathetic and disinterested in humans to the point she doesn't care if they're in trouble. [[spoiler:Kyrin]] as well, as her motivations lean towards the selfish anti-hero end of things at times. And finally, let's not forget [[spoiler:Empress Cygnus]].

* CompleteMonster: Magnus the Betrayer is the power hungry, megalomanic antagonist of the Nova storylines. Exiled years ago for abusing his powers, he sided with the arch enemy of the Nova race and carried out an attack on Heliseum, killing many, including Cadena's family. His actions eventually required the previous Kaiser to step in, ending with him performing an unsuccessful HeroicSacrifice, Magnus then taking the Nova's capital as well as their champion and protector in one fell swoop. He's shown to absolutely revel in his actions, taking pride in being a mass murderer and double crosser, joining two different forces wishing to destroy the world only to gain abilities to cause more destruction in his path. Feared by the Nova, reviled by Kaiser and Angelic Buster, and hated by the Black Mage's commanders, Magnus never bothers showing any remorse or sympathy to who he affects, and he enjoys every second of it.

* ArcFatigue: The entire Temple of Time questline. It wouldn't be bad to go out and kill 333 monsters, only if it wasn't required to kill 333 of ''every'' monster in the temple to progress from map to map. You can bypass this with a teleport rock, but if you don't have any real life money to spend or aren't in an event period offering one, you're out of luck.
