* The Demon Hunter trailer. It starts out slow, as the hunter investigates the aftermath of a demonic raid, only to discover that someone survived. They find that the whole horde has followed the survivor - and that won't stop her. From there, we get to see the full glory of actual Demon Hunter Gameplay, a combination of sadistic weaponry mixed with acrobatic finesse, and a body count high enough to ''level up''. All climaxing with a BadassBoast that ''defines'' what a merciless killing machine they are.
-->Demon Hunter: I stand alone. And if they keep coming, '''I will never stop killing'''.
* The [[https://www.youtube.com/watch?v=EgbUSsblCSQ cinematic teaser trailer]] for ''Diablo III''. The final 45 seconds are backed up by SugarWiki/AwesomeMusic with a OneWomanWail while clips are shown of the [[LegionsOfHell Legions of the Burning Hells]], Tyrael destroying the Worldstone, a meteor coming down on the cathedral, all of the rapid-fire clips ending by showing Diablo himself standing amid a storm of flame, roaring at the camera.
* [[http://www.actiontrip.com/videos/diablo-iii-wrath-movie-7877 This video]] shows the CMOA of the Angels of Heaven fight the demons.
* The Diablo-possessed Leah utters a terrifying but epic line when he stands in front of the gates of the Silver City.
--> '''Leablo:''' Even in the heart of Heaven... Angels can still ''feel'' fear.
** While very brief, the entire battle between Diablo and Imperius. By far one of Blizzard's best cinematic battles to date.
** And then, after winning the above battle, Diablo proceeds to do what no demon in creation has ever been able to do in the entire history of the Eternal Conflict, and ''bring the [[ThePearlyGates Diamond Gates]] crashing down'' as [[HellInvadesHeaven he begins his invasion of Heaven itself]]. Nothing says "shit has just gotten '''real'''" quite like this.
* Tyrael fearlessly calling out [[TyrantTakesTheHelm Imperius]], the ''Archangel of Valor'', on being a coward during the former's trial for helping Sanctuary. Bonus points for hitting Imperius's BerserkButton in the process. Then he willingly strips himself of his angelhood to stand with the humans. Lots of supernatural beings like to argue HumansAreSpecial, but Tyrael puts his money where his mouth is.
--> '''Tyrael:''' All ''I'' am guilty of, Imperius, is bringing Justice! While you hide, [[OrcusOnHisThrone cowering behind your throne!]]
* While every ''Diablo'' game has your character becoming a hardcore DemonSlaying badass capable of [[OneManArmy singlehandedly laying waste to thousands of demons]] in a manner that would do [[{{Manga/Berserk}} Guts]], [[VideoGame/DevilMayCry Dante]] and the VideoGame/{{Doom}}guy seriously proud, taking back Heaven itself from Diablo and his demons is a SugarWiki/MomentOfAwesome in every definition of the term.
* One of the reasons why people think Belial is one of the best boss fights ever is the fact that once he's dropped down to a quarter of his hit points, he sheds his false form and assumes a ''humongous'' form with new attacks, giving the vibes of an epic battle. This is even better in the console version, where they suddenly ''change'' the camera POV and make it look like you're playing games with the camera POV like ''VideoGame/DevilMayCry'' or ''VideoGame/GodOfWar''. Shows how much Blizzard has improved in terms of console ports.
--> '''Belial:''' I cast off these petty illusions! Behold, the true vision of THE LORD OF HELL!
* Before the battle against Diablo, Imperius is once again threatening to kill you simply because you're there, you're a nephalem, he hates nephalems. In face of that kind of threat, coming from an Angel and the most badass one, you just stand there and reply without fear: [[BringIt "Wanna try it?"]] That's right, your character has grown so badass, they simply didn't give a fuck that they could be facing the mightiest angel, and if he keeps acting like a {{Jerkass}} for humanity no matter the reason, your character is just ready [[DidYouJustPunchOutCthulhu to sock him right on the helmet.]] But fighting Diablo comes first.
* Acquiring one of the really good skills for the first time. For example, one of the skills that the wizard gains is Disintegrate, an arcane ''laser'' that cuts through swathes of enemies like soft butter (in normal difficulty at least, and that ''is'' when you will first unlock it). A couple of levels later, the wizard acquires a rune that doubles the width of the beam and changes the damage type to Fire. So you now have ''two'' mystic death rays burning a path through everything in front of you.
* You get an achievement for creating one by [[DidYouJustPunchOutCthulhu punching Diablo]]. ''Literally''.
* While most of the awesome is reserved for the main cast in some fashion, the [[MauveShirt Mauve Shirts]] get their moments, too. By way of an example, consider Clyfton, one of the soldiers in Bastion's Keep who's part of one of the catapult crews during TheSiege. In his own words:
--> Clyfton: "...Everyone else has gone and died, but I'll be ''damned'' if I leave my post!"
** He then proceeds to work with you to raise the catapult, hurling vitriolic encouragement at you all the while. Consider that he's got the guts to do that while demons are breathing down both your necks, instead of panicking like most folks would do.
* Killing the Siegebreaker Assault Beast in Act III. How awesome it is? Returning to Bastion Keep allows you to listen to a banter in which two soldiers mention that it took ''Captain Haile and a hundred more men just to kill the last one''. OneManArmy indeed.
* During the final fight with Diablo, he loses patience and tries to get rid of you by sending to you to the Realm of Terror, a place where you can only get out by defeating his shadow. According to him, nobody has ever succeeded in doing that... and you ''still'' manage to do it. Cue Diablo entering a VillainousBreakdown for the first time in the entire franchise.
-->'''Diablo:''' NO! This wretched light must be ERADICATED!
** It's not just that. Diablo is the Lord of Terror, meaning he's supposed to be immune to fear. ''Supposed'' to be. By escaping from his Realm of Terror, ''you made Fear itself afraid of you''.
* Freeing Auriel in Act IV restores hope not just to the angels, but also to the people in Bastion's Keep. For you, it's just a trip back to sell, salvage or stash all the loot you have gathered; for the people in Bastion's Keep, you're doing the impossible: taking the heavens back from Diablo, and not just making it back alive, but also ''winning''.
** And every step after that, Diablo taunting you with how hopeless it is, and how your efforts are useless, and you match it with proving him wrong each time, up to and including kicking his misappropriated ass.
* The Crusader makes a joke to Ithereal, which turns into one for the Nephalem as a whole:
-->'''Itherael''': Because of (Uldyssian's) noble sacrifice, I saw the inherent potential of your kind. As such, I voted with Auriel to spare mankind from annihilation.
-->'''Crusader''': I'm grateful. I'll be sure to vote to spare the angels when the time comes.
-->'''Itherael''': You jest, but that day is not impossible.
* The Crusader just lays out an endless assortment of completely understated {{Badass Boast}}s:
-->'''Crusader''': The battle approaches. What says the Scroll of Fate?
-->'''Itherael''': Doom and darkness. These heavens ruined... The angelic Host broken. Diablo is victorious.
-->'''Crusader''': Ah. [[ScrewDestiny So the Scroll is wrong.]]
* ''The Templar Reckoning'', the sidequest for Kormac, in contrast to the other two follower quests, is made of awesome. It has you and Kormac facing down the Grand Maester of Kormac's Templar Order and making him and his Inquisitors answer for the horrible things they have done to every single person they have made a Templar and stopping his plan to make Templars out of every citizen of Westmarch and beyond, with everything that this entails.
* Well, remember how Adria ended up as a KarmaHoudini in the vanilla version, buggering off through a portal in Bastion's Keep after Diablo invades Heaven? Well you get your chance to make her pay, but the build up is even more awesome. Once you're told that you might need to meet Adria to inquire about Malthael's location, your character undergoes something of a RoaringRampageOfRevenge, everything from their mouth (the Demon Hunter's especially!) is about how they are going to kill Adria for what she did to Leah, and sounding REALLY murderous at that, to the point that your Horadrim ally was starting to worry that you'll succumb to vengeance and kill her immediately before even extracting information from her. By the time you reach Adria, however, you have already told your Horadrim ally to stand back, and no matter how Adria keeps taunting you about Diablo's possible return and Leah's death... you ''don't'' give in to rage, you just keep up your TranquilFury as you deliver a most righteous retribution to that witch. Oh, and that information? You already nabbed that before the battle even began.
-->'''Adria''': Diablo will come back! He will always find a way!
-->'''Nephalem''': Too bad he won't be there to save you![=/=]And yet you will die here!
* The beginning is also an awesome moment, basically showing that above all else, the Nephalems will fight for humanity's future... and then just to be sure, tells Adria that she pretty much revoked her rights to be protected by them.
-->'''Nephalem''': Humanity will shape their own fate to the future. But you won't be there to see it.
* Malthael's introduction as the new villain in ''Reaper of Souls'', he effortlessly takes out the Horadrim guarding the Black Soulstone and subdues Tyrael without taking a scratch. Then, he delivers this truly chilling BadassBoast:
--> '''Tyrael''': The Nephalem...will stop you.
--> '''Malthael''': ''No one can stop death.''
* Malthael gives Diablo's pre-fight BadassBoast a run for it's money with three deathly chilling words:
-->Death comes, nephalem.
* After inflicting a significant amount of damage to Malthael in ''Reaper of Souls'', he will remark that the Player can not win - but his voice is full of doubt and uncertainty. Your character is such a badass that even the Angel of Death starts to realize that he's probably not going to win the battle.
* Defeating Malthael in and of itself. The one who was regarded as the leader of Angels, and who even Imperius considers with a wide degree of respect. Add to it that he infuses himself with the power of the Prime Evil itself, the fact that you still manage to take him down is really quite incredible, a fact that Tyrael himself notes. Malthael's death animation is one for the Hero and the souls Malthael contains. His death is long, extensive and painful as his very being is torn apart from the inside in stages by the souls he absorbed but can no longer contain as they seek to release themselves. A fitting end to the horrors he brought upon the realms.
* Despite the Nephalem's efforts, Zoltun Kulle survived the latest attempt on his life, albeit as a ghost like before. He takes it in stride, and while he helps with the acquisition of Kanai's Cube, he snarks at his killer from start to finish and ever-after. Given what he went through before the game's story, he has every right to it.
* This conversation, spoken in reference to you:
--> '''Lorath:''' Doesn't our friend ever tire? I've [[{{Determinator}} hardly seen [him/her] rest since we've met]]. \\
'''Tyrael:''' Now you know why [[TheDreaded angels and demons fear the nephalem]], Lorath.
* Killing a Gelatinous Sire and all of the [[AsteroidsMonster offspring that they divide into]] and getting so much stuff out of them that you'll likely go from empty to full just trying to pick up everything they dropped. To say nothing of the many Legendaries they drop, resulting in a beautiful light show of orange and green.
