* AntiClimaxBoss: Borderline -- whereas his predecessor Sturm was horribly overpowered, Von Bolt from ''Advance Wars: Dual Strike'' is ''barely'' above average at best and up against a roster full of new overpowered [=COs=]. Not to mention that the maps you battle him on are rather... pathetic, to the point where the last mission should have been called ''Mean To The End'' instead. Intelligent Systems learned from this and made doubly sure Caulder/Stolos from ''Days of Ruin'' didn't fall into the same pit trap.
* AwesomeMusic: Has its own page [[AwesomeMusic/{{NintendoWars}} here.]]
* CompleteMonster:
** Caulder from ''Advance Wars: Days of Ruin'' appears to be just an amoral scientist at first, excited by the [[TheEndOfTheWorldAsWeKnowIt recent apocalypse]], since it finally lets him give his weapons some field testing to slake his curiosity. As the story continues, his "scientific curiosity" turns out to be genocidal sadism. He has invented a virus known as The Creeper, which makes flowers ''grow underneath your skin and burst through it, covering your body with roots, stems, and flowers'', all of which you can feel very painfully. The original virus wasn't good enough for him since it only infected the young, so he decided to upgrade it. Now it can kill everyone, even faster and more painfully than before. The photo they show you of one of the victims of this new strain of Creeper is horrid. It gets to the point where, when he tries to HannibalLecture the hero about how HumansAreBastards, the [[ShutUpHannibal hero throws it back in his face]], saying that it doesn't matter if he's right, becaue he's still a monster who needs to be destroyed. [[spoiler: Caulder even reveals that he literally isn't human, but a clone of an amoral scientist that fought back and killed his creator and the OTHER clones of said amoral scientist. "Do you know what it's like to watch yourself die? ...It is FASCINATING!"]]
** The same game also has Greyfield, a malicious SocialDarwinist who preaches about ruling through fear. His crimes include: [[spoiler:scaring [[ButtMonkey Davis]] to death, messing with your units the one time he is your "ally" out of spite for disputing his [[TheSocialDarwinist darwinism]], making your force do "active surveillance" for perhaps both sadistic reasons Lin mentions, murdering [[WorthyOpponent Forsythe]] before he could try being a SilentScapegoat, and [[WeHaveReserves nuking his own men]] to kill [[AFatherToHisMen Brenner]].]]
* ContestedSequel: Days of Ruin completely changed the setting and tone of the previous games, as well as how the CO powers work, causing quite a division. Many people [[{{Sequelphobic}} declared that it would be garbage, despite not knowing anything else about it]].
* DemonicSpiders: Anti-Tanks in ''Days of Ruin''[[note]]Doesn't help that their only real weakness after they're in position is infantry which get picked off by everything else.[[/note]], Pillboxes in the first ''Battalion Wars'', Fighters and Strato Destroyers in the ''Battalion Wars 2''.
* EnsembleDarkhorse: Lash is insanely popular among ''Advance Wars'' fans. Her trademark {{evil laugh}} and the events in ''Dual Strike'' might be a contributing factor.
* FandomBerserkButton: Here's a tip for being taken seriously in the Advance Wars communities: never ever suggest a sniper unit. Something about such a thing being impossible to balance right or something.
* GameBreaker:
** Infantry spam in particular. Though this trope was bound to happen anyway with CripplingOverspecialization.
** PurposefullyOverpowered: The two boss [=COs=] Sturm and Caluder (Von Bolt tries to be this, but isn't quite strong enough). Nell and Hachi probably count, too.
** Kanbei and Grit are often cited as being game breakers from their [=AW2=] incarnations onwards. Although, Grit has been considered lower after DS games.
** Colin also, although he doesn't fare too well against [=COs=] that get defensive boosts.
** Sensei is called broken old man, for a good reason.
** And if we were to toss the various Force Rank upgrades and potential tag team combinations from AWDS, we'd probably double the size of this page.
** Isabella, her CO Power is, literally, Will's and Gage's '''combined''' with no drawbacks. Plus an attack boost to every unit type. This basically dominates everything. She is, to say the least, frowned upon by competitive players.
*** The series now has [[GameBreaker/NintendoWars its own page]]. Go nuts.
* GoddamnedBats:
** The 'Mech Rush' tactic from ''Advance Wars'' is based on this trope. In particular, Sensei's CO Powers - spawning Infantry or Mechs on every city he owns - can quickly drive opponents insane.
** Colin, with his power to increase his funds by half every couple of turns on top of normal income and having cheaper units, can out Mech-Swamp even Sensei, and when partnered with Hachi or Sensei in Dual Strike, this is made even worse.
* LauncherOfAThousandShips: Eagle and Hawke.
* MoralEventHorizon: Waylon probably crossed it a long time beforehand, but [[spoiler:Waylon (on Greyfield's orders) murders Forsythe execution-style, in front of just about everybody, and keeps his smug-ass attitude rolling the whole time.]]
* NightmareFuel:
** [[spoiler:The Creeper]] in Days of Ruin. Lin, being how she is, makes it worse by theorizing whether [[spoiler:the infected feel the roots moving just beneath their skin.]]
** Knowing the [[CompleteMonster guy]] who created it, the answer is most likely yes.
** Speaking of that guy, how about the extreme close up of him that shows up midway through the final mission, with him sporting an ''incredibly'' disturbing SlasherSmile? Worse, the Sound Room randomly cycles through the game's CG artwork, meaning it could show up again there when you least expect it! It's practically a Screamer.
* ReplacementScrappy:
** Von Bolt, who replaced Sturm.
** Jake replacing Andy as the main character. While Andy wasn't exactly the most interesting character in the world, a lot of people would prefer him over Jake's JiveTurkey routine any day.
* StopHelpingMe: Olaf's snow powers can screw over allies as badly as they do enemies.
** He also EXERTS this personality several times, notably the T-Minus 15 mission in [=AW2=].
* ThatOneLevel
** Crystal Calamity in ''Dual Strike'', Their Finest Hour in ''Battalion Wars 2'', and Sunrise from ''Days of Ruin''.
** [[BrutalBonusLevel Bonus Mission 3]] in ''Battalion Wars''. Lots of heavy tanks under your command? Check. A LOT of enemy bombers? Check. Your tanks being [[EscortMission mission-critical]]? Check. [[OhCrap Not a single]] [[AntiAir AA unit]] [[OhCrap to save you?]] '''[[ThisIsGonnaSuck OH SHI--]]'''
** Sea Fortress and Sinking Feeling from ''Black Hole Rising''. Given Sea Fortress is a highly tactical mission with limited resources and an emphasis on unit placement and management, while Sinking Feeling is a highly strategic mission with a time limit and a very freeform (thus hard to {{Walkthrough}}) general strategy, it's easy to see where this comes from.
** "Waylon Flies Again" in ''Days of Ruin."
** Sunrise was the [[TheVeryDefinitelyFinalDungeon last mission]] in ''Days of Ruin'', where you finally face [[FinalBoss Caulder]]. It's supposed to be frustrating and difficult... and the fact that Caulder is arguably more broken than Sturm makes it even more fun.
** Greyfield Strikes from "Days of Ruin" can be very frustrating, depending on which units get sabotaged. Having landers and gunboats unusable in the first few turns will make the mission much harder and longer than it actually is.
** Waylon Flies Again from "Days of Ruin" has caused some players to give up the game entirely.
** Trial 7, known as Tatter River, looks like a modestly challenging trial map - 4 Commanders and plenty of Airports and Factories. But upon closer look, all of the headquarters are next to four Factories and are surrounded by rivers. Rivers can only be traversed by Infantry, Mechs, and Air Units - all of which extremely weak against Anti-Air unit attacks. Guess what the unit will be greeting you in large numbers when you try to capture a base in large numbers?
* TastesLikeDiabetes: Isabella's theme in ''Days of Ruin'', [[SoundtrackDissonance despite the]] DarkerAndEdgier setting. That doesn't mean the song isn't good. As it's a song from Advance Wars, it pretty much has to be [[CrowningMusicOfAwesome really good]].
** Sasha's theme from Dual Strike is very similar, though this time it doesn't clash with the setting.
* UnfortunateImplications - In the Japanese versions, the Orange Star army was originally called the "Red Star" army. You can see why they changed it for the international versions.
* {{Woolseyism}}:
** Most of the [=CO=] names in the English localizations.
** Particularly ''Days of Ruin/Dark Conflict'': Nearly every name (and themes), many missions, several units (sometimes contradicting the same unit name in earlier games) and the entirety of the script differ due to an independent European localization. The European version is closer to the original Japanese, for the better or worse.
