* EnsembleDarkHorse: '''Splash Woman.''' Mainly due to the fact she's the only female Robot Master.
** Jewel Man, Galaxy Man and Tornado Man are also surprisingly popular.
* SugarWiki/FunnyMoments:
--> [[OverlyLongGag "And this time! And this time! And this time!"]]
* GameBreaker: The Jewel Satellite, possibly the best shield weapon in the series. To explain, it stays up until dismissed or collides into a strong enemy. And it ''reflects shots back'', making Sniper Joes (who have MoreDakka now) a joke.
* StrawmanHasAPoint: Wily does raise some good points about the morality of scrapping sentient robots, even if it's just to get slave soldiers to smear the name of his rival.
* TheyChangedItNowItSucks: Mega Man's loss of his 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.
* TheUntwist: Don't act like you were surprised when it turns out Wily was behind everything. Especially if you read the achievements list.
