History YMMV / MegamanX

** The term Reploid canonically stands for "Replica Android". While many assume this is in reference to them being replicas of X (and thus, X and Zero are technically not reploids), this is never actually stated, and according to other media such as "Rockman X The Novel: Irregulars Report" the term is meant to refer to their replication of human-level cognition, or "replicas of humans". This would also answer the question on whether or not X and Zero can technically be considered reploids.

** Because of his long hair, sleek body and odd-looking lights on his chest, many people unfamiliar with the series think Zero is a girl at first.

** Who is ''really'' to blame for the events of the ''X'' series? On one hand, people blame Dr. Light for even coming up with the idea of giving robots free will in the first place, citing that [[AIIsACrapshoot the results were predictable]], regardless of intentions. On the other hand, people put the blame on Dr. Cain for not taking ''nearly'' as many precautions when making the Reploids as Light did with X, [[JustThinkOfThePotential only looking at the results and not taking into consideration the consequences of not properly testing them]]. Despite all this, it wasn't until Sigma was infected by Dr. Wily's Maverick Virus that things truly took a turn for the worse, so maybe it's all Wily's fault? And ''that'' wouldn't have happened if Sigma wasn't so cocky in his original fight with Zero, so maybe it's Sigma's own fault? Another camp believes that while Light and Cain both had the best of intentions they either overlooked or underestimated certain variables that were completely beyond their ability to control ultimately resulting in a powder-keg primed to explode regardless of who, when, why, what, where, or how it was triggered.

[[TakeAThirdOption A third camp]] places blame on ''both'', saying that Light should have known not everyone would follow his safety standards and that Cain should have paid more attention to the amount of work Light put into X. It can be argued that neither are fully to blame - they both had their faults, but it wasn't until Sigma was infected by Dr. Wily's Maverick Virus that things went truly bad, so maybe it's all Wily's fault?

** Many fans believe that ''X'' series should've ended at ''X5'', as many key plot points (such as X and Zero's destiny to fight despite being best friends) were resolved there, and it leaves off in a perfect spot for the ''Zero'' series to begin. Inafune allegedly told the dev team to wrap the story up there, and even seemed to regret 'X6' to some extent. However, ''X6'' leaves the story nicely wrapped up as well, including Zero sealing himself away for the ''Zero'' series, so there are fans who argue that ''X6'' works as an even better finale. But since the series continued with ''X7'' and ''X8'', meaning there are also fans who refuse to see these sequels as canon either. Zero's ending in ''X6'' is changed to take place [[DistantFinale after the end of the series]], allowing those sequels to be made, but the debate won't stop even with that.

** Many fans believe that ''X'' series should've been put to rest at ''X5'', as many key plot points (such as X and Zero's destiny to defeat each other despite being best friends) were resolved there, and the plot picks up in the fitst ''Zero'' game. Inafune even indeed stated that the game has the "finality" feel to it. Others would be fine with seeing more ''X'' games to stick with the characters and expand on the plot points introduced in the later games. Of course, by this account, ''X5'' is still the end of the series, as each post-''X5'' game has a time period during the three years the epilogue states, while ''X6'' took place after Sigma's defeat in a few weeks of ''X5''. As an additional note, Zero's ending in ''X6'' is supposed to take place [[DistantFinale after the end of the series]], allowing sequels to be made. Of course, the debate won't stop even with that.

* GrowingTheBeard: Many believe that the ''X'' series did so with the jump to the UsefulNotes/PlayStation, which allowed both the gameplay and story to reach new heights that they never could have within the SNES' limitations.

** Sigma [[BackFromTheDead coming back from the dead]] and/or [[HijackedByGanon being revealed as the games real villain]] in almost [[OnceAnEpisode every game in the series]][[note]]Though in X5, this doesn't happen as Sigma is acting out a plan made with a partner who's implied to be Dr. Wily, and in X6 and X8 he technically wasn't the main villain, but was simply resurrected as a convenience by Gate and Lumine respectively, and he's completely absent from ''Command Mission''.[[/note]] is another infamous cliche that fans will never let the series live down.

** Any mission involving the use of the Ride Chasers. Ironically, ''X6'' doesn't have any of these levels, though most of the game's stages are {{Scrappy Level}}s enough. ''X8'' made up for it with ''two'' Ride Chaser stages, though.

** For the games that effectively ''kickstarted'' the idea of moral complexity and detailed character relationships in the ''Mega Man'' franchise, to the point that virtually [[VideoGame/MegaManZero everything story-focused]] [[VideoGame/MegaManZX in the franchise can be]] [[VideoGame/MegaManLegends pointed back at these games]] (primarily ''[[VideoGame/MegaManX4 X4]]'' and ''[[VideoGame/MegaManX5 X5]]''), newcomers are often staggered to realize that in spite of this, the games are incredibly [[ExcusePlot straightforward, to-the-point platformers]] that leaves entire characterizations, relationships, plot points and most of their more complex ideas [[AllInTheManual in supplementary materials]] at best or skim over them completely because they have to be short, digestible games completable in about an hour or two at worst, even ''[[VideoGame/MegaManXCommandMission Command Mission]]'', the sole RPG of the bunch, barely does anything with its own genre and chooses to be a straightforward adventure formatted like a linear ''Mega Man'' game instead. In effect, [[Franchise/MegaMan being part of a series not really known for having rich, complex stories]] keeps these games from exploring more of Mega Man and its lore.

* CreatorsPet: It's no secret that Keiji Inafune's favorite character is Zero. Inafune designed him hoping for him to be the new Mega Man, only to instead decide to pass X to Hayato Kaji. He wanted Zero to be playable as early as ''X1'', and he was the one who got Zero to come back in ''X2''. His comments in the ''Official Complete Works'' book also indicate he was very protective of who got to do Zero's illustrations, doing them himself up until ''X4''. Fans assume this is part of why he's such a SpotlightStealingSquad character for X in the series. Unfortunately, Inafune seemed to regret this and wanted to put X back into the spotlight with ''Maverick Hunter X'', only for that series to never get a sequel.
