Several, given [[ForegoneConclusion all the Robot Masters die]], but there's some special mentions:
* ''The Quick and The Blue'': The entire song is basically Quick Man trying to come to terms with [[YouCantFightFate his eventual death]].
* ''Programmed to Fight'': Though [[EpilepticTrees ambiguous]], it appears Crash Man commits suicide with his last ounce of will so that Mega Man can retrieve his weapon.
* ''Promise of Redemption'': Bubble Man's entire life was a joke, and he wanted to give his ridiculous existence some sort of meaning and respect by avenging the murder of his brothers. But we all know his death will be just as meaningless as his life.
* ''Everything'' about Proto Man; his song ''I'm Not The Break Man'' is about his depression from being rejected by Light in favor of Mega Man. "I had a name, my father called me Blues," Light tearing his heart out to put it in Mega Man, and "I'm not broken; I'm not the break man". In the end, even ''Melody From The Past'' as he begins to accept his situation and forgive his family is heartbreaking. ''All the way through''.
-->''There is a song I hear, a melody from the past./When I woke for the first time, when I slept for the last./You are the one, the hero who will stand./Do not blame Father, he is only a man.''
* ''The Message From Dr Light'', where Light is lamenting how he has to continuously watch his "son" go out to stop Wily, knowing this is his fault at least in part.
* ''History Repeating'', both parts, where Mega Man laments his role in constantly having to stop Wily--complete with a somber take on the ''Mega Man 3'' title theme.
* ''Continue'', which describes how despite all of his talk about wanting to just do it one last time, Mega Man will always keep fighting and always knew that the war will never really end.
* One verse in ''Gamma Unchained'' has Wily describe what happened with Proto Man-
-->''I thought that I could bring the dead back/Broken shell, rusted red with age/I gave him power, a new heart/It filled too quickly with his rage.''
** In addition, Wily regretting the dark path things have taken, but finding himself unable to give up. The war has gone on so long, and so much has been lost, that he has to make the end justify the means. And so he unleashes Gamma.
---> ''Forgive me for what I have done/I've never felt the need to confess/This war has gone on much longer/than any of us would have guessed./I've heard the names that they call me/some sting, some can't help but ring true/I have to live with what I've done/Find the strength to continue''
---> ''Tell me why I'm the one that they fear/And for ''him'' they cheer.''
* It seems like Air Man's entire reason for being evil is because his power causes him to continually push everyone else away, forcing him to live a bleakly lonely existence. He seals it with the line "If I can't walk among them, then I will walk the world alone." If someone could just give him a hug...
---> ''Do you know what it's like to be built this way? With only the power to push others away?''
** And if one reads the vengeance motivated lines of other songs like Wood Man and Heat Man as pertaining to the other Robot Masters, Air Man's loneliness may be more self-inflicted than anything.
* ''Fly On a Dog'', with Mega Man lamenting that even with Rush at his side, he feels utterly alone and betrayed by his father.
--> ''How dare he call me son? I'm clearly a weapon, a loaded gun.''
** The song as a whole can be one big Tearjerker. Much of the chorus is about all the amazing and impressive things Rush can do, but the song ends with what Mega Man considers to be the most important thing, a shoulder to cry on with Rush.
-->''Shoulder to cry on a dog.''
* In ''I Want To Be The One To Watch You Die'', Dr. Light has decided to end the war with Wily once and for all, but the fact that he has to order Mega Man to do it really hurts him.
--> ''Son. For one who wants so much to be human, I fear you only see the worst of us. How many more lives must end before he meets his? Put a stop to this. ''End him.'' They will forgive you... but I wonder... Am I right to ask this of you?''
* Dr. Wily's entire personality - the way he knows that people call him a villain and Dr. Light a hero, but he legitimately doesn't understand why.
-->'''Gamma Unchained''': Tell me why I'm the one they fear, when for ''him'' they cheer?
-->'''Look What You've Done''': I only ask that you see what I see. This is the answer, why won't you ''believe''?
** Also in ''Look What You've Done'', where Wily seems to imply that he doesn't want Light to be hurt or even vilified: he simply wants his old friend to realize that Wily's ideals were right.
-->'''Look What You've Done''': ''I hope history is kind to us all/I know they'll blame me for the fall/I wish there was a better way out/But there's no better way out.''
** Wily's desperation eventually causes events to spiral entirely out of his control. By the end of ''History Repeating: Blue'', it's not clear that he has any control over either Gamma (''What good is power when you're out of control?''), Proto Man (''I gave him power, a new heart / It filled too quickly with his rage''), or even himself (''I know that I am no longer the same''). Combine that with his belief that he's actually the hero, and his frustration with the fact that he's been unable to convince literally anyone else of that fact, and it's hard not to feel a little bit sorry for the guy, even if everything is ultimately his fault.
* Flash Man's last words in "Blue Like You" are pretty heartbreaking:
-->''This moment will last forever/One last moment together!''
* Needle Man. He's forced to be locked away far underground so that he doesn't harm anybody, and wants to take back all the damage he's accidentally caused. He's so lonely and miserable that part of the reason he's happy about Mega Man coming to fight him is it means that for a short while he won't be alone, with [[SuicideByCop another reason]] making itself apparent by the last line.
-->''I'm not a bad guy/I'm just designed that way!/No matter what I try/I can't help but hurt those close to me/And I can't see a way out this time''
* ''Afraid of the Dark'' is about Shadow Man consciously losing his former personality to darkness after Dr. Wily repairs and reprograms him--and he's terrified.
-->''The me that used to be here/Has gone away, but I can't say where/I fear I may have killed him/I'm so scared''
* ''[=GeminiEye=]'' ends with both personalities realizing they'll never see the sunrise again. And likewise, the entire ending monologue from one twin, as they slowly become aware that they're both about to die-
-->''The clues had led us to a dead end. How dead? We would soon see. There was a sound as the door locked behind us. We were trapped... ...and the Gemineye seemed anything but surprised. The night was seeming to stretch on forever, and for us, it would. This was the end. And now, the gloves were off. The truth was out. The hired gun was on his way, and we were both as good as dead.'' (Slowly getting angrier) ''But I looked to the stars and swore- [[MutualKill if we were both taking the big sleep, I'd take the rat out myself!]]'' (Gunshot)
* ''Harder than Steel'' follows Hard Man as a retired boxing champ in the style of an 80's film training montage as he gets back into shape to fight Mega Man. We get to hear how much his fans loves him and believe he'll win like in his old championship days, only for him to lose in the end. In his last moments, he can hear the crowd cheer on him still.
-->''You're going down/It's the final swing/As the lights go out the crowd begins to sing:/"Harder than Steel!"''
* ''Bloody Tears'' off the Belmonts EP, based on the song of the same name, tells the tale of Simon's fight against the darkness of Dracula... though since the song appeared in the sequel, Simon's Quest, it details the effects Dracula's curse upon Simon is having, and that even if he does kill Dracula again, he's on borrowed time thanks to the toll the quest is having on him.
-->''"And now, the quest consumes his heart. A marked man slowly torn apart. In this eight accursed years, he's been drowning in his tears."''
* ''Wicked Child'' off the Skulls EP covers Dracula's anguish and hatred after not only his wife Lisa is burned at the stake, but his son Alucard seems to be determined to protect her murderers. But all the same, he feels even ''more'' distraught at the idea of having to kill him to enact his vengeance.
