* The fact that ''Dr. Light'' is singing ''I Want To Be The One To Watch You Die''.
* ''Beneath the Steel'', a metal track all about Bomb Man going straight-up MadBomber with his new emotions. The MetalScream of “Cue Explosion!” and “Robotic Emotion!” don’t help either.
* Air Man's MotiveRant near the end of ''The Annihilation Of Monsteropolis'', flipping from [[TranquilFury quietly furious]] at humanity rejecting him due to his bizarre appearance into full-on AxeCrazy fury in the blink of an eye:
-->Up in the sky, ten miles high\\
A man stands above the city he will destroy.\\
Built from airplane parts\\
His propeller spins as he thinks to himself:\\
''"'''[[TheDogBitesBack I will destroy these people.]]'''\\
[[LonersAreFreaks For if I can't walk among them]]\\
[[FinalSolution Then I will walk the world]] '''[[FinalSolution alone]]'''.\\
There will be a fire in the sky...\\
'''[[SuddenlyShouting AND YOUR DOOM WILL RAIN DOWN!]]'''\\
BUILT FROM PIECES OF SR-71s!\\
AND PLANES THAT CRASHED IN WORLD WAR TWO!\\
'''[[OmnicidalManiac THERE WILL BE A TOMBSTONE WITH THE PLANET EARTH ENGRAVED ON IT!]]'''"''
* ''Afraid of the Dark'' is about Shadow Man [[DeathOfPersonality consciously losing his former personality to darkness]] after Dr. Wily repairs and reprograms him... and he's terrified. At around 3 and a half minutes in, the darkness sings ''back'' to him.
* ''The Haystack Principle'' gets nightmarish when Needle Man starts singing about [[EvilMeScaresMe how much he loathes and fears his new body]], while another voice repeatedly confirms that this is who he is.
* The prelude to ''I'm Not the Breakman'', called simply ''The Red Song'', can be this without much context for it. It's a wordless audio track of Mega Man running to the site he'll meet the mysterious Break Man. And then he hears something in the distance, beyond the churning machinery. A song, sounding as if it's being played on a chime. A machine explodes as the blue hero's opponent teleports in, Break Man's systems powering up as a raging fire can be heard.
* Gamma, as seen in ''Gamma Unchained''. His first conclusion upon activation -- announced in an unnervingly deep and distorted mechanical voice befitting [[MechanicalAbomination such a behemoth]] -- is to kill everything that's not a machine because that's the only way to ensure peace. And that's not even getting to the [[JumpScare loud, horrible cry]] of "'''[[HellIsThatNoise GAAAAAAAAAAMMAAAAAAAAAAAAAAAAAAAAAAA!]]'''" as it happens.
-->'''All systems online.'''
-->'''g:\GAMMA>\sys/activation'''
-->'''g:\>[peacekeeping]/calculation…'''
-->'''[[FinalSolution g:\>…[solution\extermination] ]]'''
* The barely-suppressed rage in Gemini Man's voice at the end of his spoken narration in ''[=GeminEye=]'', which is shortly after [[AmbiguousSituation followed by a gunshot]].
-->But I looked to the stars and I swore:\\
''"If we were both taking the big sleep...\\
'''[[MutualKill I'd take the rat out myself!]]'''"''
* ''Out of Time'', a cover of the final level music for the first ''VideoGame/CastlevaniaI'', covers the very real threat of Dracula's revival, ending on a chilling delivery of the chorus line's final verse as the music halts.
-->Tonight, the lord of darkness ''shall. '''Rise.'''''
** The lines "There's something here" and "This can't be real" underscore how surreal and paranoia-inducing Castlevania can be, even for Simon Belmont.
* ''Cracked Skulls'' portrays Skull Man as an avatar of vengeance, able to feel the spirits of the Robot Masters Mega Man has destroyed urging him onward to kill Rock in return for killing them.
-->''"The reaper becomes grim''\\
''The daylight, it grows dim,''\\
''When bone cleaves steel."''
