* Just about anything Proto Man related, specifically when he deletes Magic Man, Quick Man, and Bubble Man each with one stab from his sword. Albeit Mega Man's the one who weakened them, but still.
* [=DesertMan=]'s scenario. When Sunayama's finished explaining his EvilPlan to Chaud, just as Chaud is about to hand his PET over to the villains... Lan spins around a corner, shouts "MEGAMAN, ATTACK!", and ''tosses his PET case'', [=MegaMan=] and all, right at Sunayama's head (as you can imagine, this doubles as a CrowningMomentOfFunny). In a series where almost all combat is virtual, this was very refreshing.
* In the fourth game, [=ShadeMan=], who's completely immune to [=MegaMan=]'s attacks, demands that he and Lan return the [=DarkChip=] they found. Out of options, [=MegaMan=] tosses him the chip... and then ''shoots it in midair'', destroying it. [=ShadeMan=] is not pleased. (Fortunately, [=MegaMan=] gets a way to damage him in the ensuing battle.)
* In the sixth game, [=MegaMan=] gets taken over by a giant Internet monster SealedEvilInACan, and you have to drag someone else' Navi (Heatman or Aquaman, depending on version) into Internet Hell to defeat him. As much as that ''could'' be a Moment, given that you just defeated the main character fused with a massive cybermonster while playing as either a baby with a fishbowl on his head or a manic zippo lighter, that's not the awesome. A few scenes later, [=MegaMan=] wakes up from his beating... and the Beast roars back to life. Lan and his dad are panicking. And then your substitute Navi ''[[GetAHoldOfYourselfMan Bright Slaps]]'' Rock back into control. Win.
** Actually, by that time (when you need to save him from that cult in the Undernet, not when [=MegaMan=] first absorbs Gregar/Falzar), I believe you already have the first three crosses(Aqua/Heat + Tengu/Slash + Tomahawk/Elec), so you can use any of those three. Saving [=MegaMan=] with Elecman has never felt so epic.
** And following the last prelim of the contest, you have access to ''all'' Link Navis. So, technically, you can send the GrimReaper into Hell to go save [=MegaMan=].
* Again in the fourth game, this troper considers the ending a crowning moment of awesome. [[spoiler:After defeating Duo.EXE, and with only an hour before a computer-controlled asteroid collides with the Earth, [=MegaMan=] tries to move the wheel controlling it, but it would not even budge. However, after the whole world starts to cheer for him, Lan goes Full Synchro with [=MegaMan=], and the wheel that wouldn't even budge now spins so hard that it's a surprise that it doesn't fly off its axis.]] With the music to go along with it, it was perfect.
* Let's be honest, Mega Man does something selflessly heroic and suicidally stupid at the drop of a hat to the point where it stops being awesome sometime around game 2. That said, the ending of [=BN3=] felt like they finally figured out how to do a proper Heroic Sacrifice with all the awesome due to such a moment. Even his resurrection after the credits is so well done as a [=CMOH=] that finally, FINALLY Mega has some Awesome in his pants. And then they hit us with [=BN4=]...
* Anyone forget Wily's [=CMOA=] at the end of [=MMBN5=]? He's an old man who walked into an EXPLODING VOLCANO, just to use a brilliant combination of the ResetButton and a BrightSlap to allow his own son a chance at redemption, and BOTH of them survived!
* From [=MMBN5=]: Team Colonel, Baryl {{Bright Slap}}s Lan/Netto out of a HeroicBSOD and tells him to quit whining and kick ass. He does that, ''and you get to control COLONEL HIMSELF!''
-->'''Colonel''': ''[[BadassBaritone Let's go, Lan Hikari!]]''%%
** Team Protoman gave us Protoman's exclusive unbridled awesome, and Enzan/Chaud took a punch from Lan and turned it into a RousingSpeech that basically said "take that aggression, and do something positive with it".
* [=MMBN3=]: The entire scenario where Lan and Mega Man are kicking viral ass to save Mamoru from dying was so ManlyTears inspiring that the whole scenario is a gigantic CMOA for the series in general!
* [=MMBN4=]: For those who say this game sucked, here's one moment of awesome no one can deny. Lan made some very questionable moral decisions throughtout the game, and Regal's attempts at a WhatTheHellHero speech at the end were destroyed by the simple fact Lan still gave a damn about humanity, and Regal didn't. The game's story was thin, but it was a barely disguised morality tale that proved that those who ultimately see the good in humanity and are willing to fight for it are the best hope our race has of survival....literally.
** Bonus points for being the impetus that gave Lan, Yuichirou, AND Wily the chance to ultimately prove that point by the end of [=MMBN5=].
* [=MMBN6=]: Joe Mach's awesome [[spoiler:HeelFaceTurn]], courtesy of beating the piss out of [[spoiler:his former World 3 allies]] because his conscience couldn't stand the thought of those assholes hurting a child.
* Back to [=BN5=], there's the Brain Navi of both games beating the living shit out of [[spoiler:the impostors of himself and [=MegaMan=].]] Cool when [=SearchMan=] does it in ''[=ProtoMan=]'', but more awesome in ''Colonel'', considering the fact that your Brain here is ''[[TookALevelInBadass NumberMan.]]''
* The very end of the series. [[spoiler:[=MegaMan=] has been taken over by the Cybeast. Lan can't do anything to save him. The Megabeast then warps over to Iris and Colonel, weak from fighting the opposite Cybeast. The two unite to form the original Colonel with the emotion that became Iris. Colonel then rushes at the Megabeast, '''''tears the Cybeast soul out of his body in a single strike''''' and then performs a HeroicSacrifice to destroy it once and for all.]]
* The games themselves usually highlight moments of awesome by setting them to a rendition of each game's main theme. Special credit, however, goes to the Gamecube spinoff ''Network Transmission'': this game doesn't use its own main theme for heroic moments, they use ''[[MegaManNTWarrior Kaze wo Tsukinukete]]''[[note]]Break Through the Wind[[/note]]. It's awesome charging towards the Final Boss with the triumphant refrain of the anime theme carrying you forward.
* Also, from Network Transmission, if you avert doing NotQuiteTheRightThing, you get to take the Professor out with style. [[spoiler: While the Professor taunts Lan and Mega about how defeating the Life Virus R didn't ultimately stop him, his mockery dies in his throat when he realizes the Officials are ''on his doorstep''. Turns out, Zero owed them a favor for sealing the virus he was generating, and used the leftover viruses infecting the Professor's own computer to sniff him out]].
-->'''[[spoiler: Zero]]''': ''[[IronicEcho Is that despair I see?]]''
* Beating [[BonusBoss Bass.EXE]]. Always.
* The fight against [=Serenade.EXE=] is also awesome. That [=MegaMan=] gets crowned ''[[AsskickingEqualsAuthority King of the Undernet]]'' for winning is the cherry on top.
* The Bonus game content for both the third and fifth games are each minor story arcs unto themselves, each culminating with a FinalBattle against a BonusBoss with some of the heaviest SuperWeight in the entire plot. As tough as it is to get there, the payoff is entirely worth it.
