These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: The Megas
Alternate Character Interpretation: Not only are their own characterizations of the character this, but even within the songs themselves this can be applied. Is Flashman gay for Megaman, or just afraid of his power? Does Heatman want to burn the world For The Evulz or because he's insane (or because this is how he mourns)? Are people terrified of Air Man because of his monstrous appearance or because he's an insane robot built by a mad doctor with the intent to have him kill them?
Quick Man's song suggests he's trying to say Screw Destiny by killing Mega Man.
Does Roll reciprocate Magnet Man's feelings, simply trying to protect him from Mega Man, or does she want nothing to do with him?
Continue is basically a case of Alternate Song Interpretation, as while it's clear the song is about Mega Man, the fandom is still not sure who's supposed to be singing it to him. There are strong cases for Dr. Light and Roll, and even Dr. Wily and Proto Man.
Accidental Innuendo: Probably unintentional, but Woodman is the master of machines... and of the birds and the bees?
Well, seeing that he is Wood Man...
Ear Worm: The entire band qualifies; specially if you're a massive Mega Man fan.
Fandom Rivalry: There's a one with The Protomen, due to them both being Mega Man bands that involve lyrics (with absolutely nothing else in common). Jokingly brought up by the Protomen when their site was hacked, as they joked that it was the Megas fault.
Foe Yay: Blue Like You. Oh dear God where do we begin...
How about the chorus?
Hey Mega Man, join my side/And let me stop this moment in time/You'll be mine, forever.
However, it doesn't appear to be a random choice to give him the Foe Yay. He does seem to have a Freudian Excuse for this rather... Freudian goal:
What Mega Man and my brothers don't know / Is this flash is all for show ('cause inside) / there's nothing there, and there's nothing to me / I'm empty and I'm hollow!
This flashy suit and this flashy stage / I use only to hide (the fact that)/ I am lonely, and I need somebody / Like Mega Man, by my side!
Growing the Beard: The general consensus about the MM 3 album; Get Equipped was lighthearted but a bit formulaic, while the new album has deeper lyrics and different song styles and themes.
Ho Yay: Listen to Hell Has Frozen Over and try to say that it doesn't smack of a love declaration between Fireman and Iceman.
