History YMMV / MegaMan9

* FanartAtFirstSight: Splash Woman's reveal really got artists going as, save for Roll, the OG series never had another female robot, let alone a female robot master before.

* SeinfeldIsUnfunny: In 2008, the idea of [[{{Retraux}} modern video games deliberately made to look and feel like much older games]] was very rare (outside of fan works) and difficult 2D platformers had largely fallen out of fashion in favor of newcomer-friendly 3D games (the closest you'd get to a mainstream [=2D=] platformer was ''VideoGame/NewSuperMarioBros1''), so Capcom doing both at once was a very bold move. Today, retro throwback games (be they platformers or just games that use pixelart) are a dime a dozen, especially in the indie sphere, making ''Mega Man 9'' and ''[[VideoGame/MegaMan10 10]]'' harder to appreciate (the fact that ''VideoGame/MegaMan11'' finally made the jump to 3D didn't help either).

* GameBreaker: [[GameBreaker/MegaMan Shares a page with the rest of the franchise.]]

** [[DirtyCop Fake Man]]'s weakness is chuckle-worthy. [[spoiler:It's the [[GemstoneAssault Jewel Satellite]]. [[DontExplainTheJoke You're]] [[FridgeBrilliance bribing him to stop]].]]

** Removing the quick weapon swap introduced in ''VideoGame/MegaMan7'' was reviled by fans. Another reversion from ''7'' and ''8'' was checkpointing for the Wily Fortress, meaning that you'll have to restart it all over if you need to restock at the store partway through (and ''9'''s fortress is ''very'' thin on E-Tanks).

* WhatCouldHaveBeen:
** Hornet Man was originally going to be a woman, though that concept would later be revived for the Archie Comics as Dr. Lalinde's Vesper Woman.
** A flying squirrel enemy that was the predecessor to the Morgun Mavericks from ''VideoGame/MegaManX2'' was originally going to debut.

* OlderThanTheyThink: This isn't the first time Dr. Wily has done a MonsterProtectionRacket, nor is it the first time he made a [[spoiler: robot copy of Dr. Light]]. He first tried both of those things in a 1994 manga series called ''Rockman: Yomigaeru Blues''. [[note]] His methods of said racket during Yomigaeru Blues and Mega Man 9 differ, though, in the manga itself he has the Wily Patrol, a squad of the Robot Masters from the first 3 games as well as Enker and Punk to bring the "evil robots" to justice, while in the game, he convinces Dr. Light's first set of Robot Masters that were made without his former colleague's help [[VillainHasAPoint that they still have purposes even after their expiry date]], before using them to frame Dr. Light for Wily's crimes. [[/note]]

* GameBreaker:
** The [[GemstoneAssault Jewel]] [[OrbitingParticleShield Satellite]] is widely seen as the best weapon in the game, the best shield weapon in the ''Classic'' series, and one of the best shield weapons in the entire franchise overall. The shield you deploy is capable of ''reflecting shots back'', making enemies that rely on MoreDakka such as Sniper Joes a complete joke. It also stays up until dismissed or until it collides into a strong enough enemy — while it does deal a paltry two points of damage, any enemy with two HP or lower is destroyed while the shield simply stays up. It even plays a nice role in ItemFarming, if used against certain enemies that shoot projectiles that leave pickups when destroyed. As with most shield weapons, its most notable weakness is its high cost (four units per usage, for a total of seven uses), but even that is a small price to pay.
** The [[LaserCutter Laser Trident]], while not to the level of the Jewel Satellite, is still a very powerful weapon in its own right. The bullets you shoot travel very fast, deal two points of damage and pierce through enemies unaffected. Essentially, it works similarly to the Charge Shot from the original games but without the need to charge and the ability to fire it twice instead of waiting, making it spammable and a significant upgrade to the nerfed Mega Buster. The icing on the cake? It consumes one unit per two shots, giving it reasonably high ammo.

** Mega Man's loss of the Charge Shot and Slide and their transfer to Proto Man. Many find that it makes his playstyle feel backwards and blander than it once was, while Proto Man isn't quite the right substitute because he takes double damage and knockback from everything.

* SequelDifficultySpike: A '''huge''' one, as while ''8'', the game preceding it, is seen as among the easier enteries, this game is considered to be on par with [[''VideoGame/MegaMan1'' the first game]], in other words, it competes with that game for being the most difficult of the classic series. * SurprisinglyImprovedSequel: While ''8'' is still seen as one of the weaker titles and knocked the ''Classic'' series out of commission for a long time, ''9'' resurrected its popularity and is still often held as one of the franchise's strongest entries.
