Think about the way Etemon came back. As explained on this blog, "after being thrown into Digimonís equivalent of Glitch City and merging with what appears to be a canon Missingno, not only did Etemon come back, but he came back better".
The first time Agumon and Gabumon digivolve to Mega.
Angewomon V.S. Lady Devimon.
Also doubles as a Moment of Funny
The first time Patamon digivolves to Angemon
Heck, anytime the kids' digimon digivolve.
Joe, starting when he moves to protect the group and proves that he's not the klutzy coward he can come across as:
Climbing a mountain to get the lay of the land, and then jumping off a cliff to try and get the Black Gear out of the flying Unimon. He gets thrown off in mid-air.
After being kicked around, cowed and pretty much enslaved at a restaurant, he jumps off a roof onto an evil Digimon to save TK. TK escapes, but Joe ends up being squeezed like a tube of toothpaste. Regardless, he tells Matt to defeat Digitamamon instead and not worry about him. It's this act of selflessness that causes Matt to realize the Power of Friendship and gets his Crest to glow.
After promising TK's mother that he'd take care of him, they get thrown off Ikkakumon and are all drowning in Tokyo Bay. Joe manages to dive down, drag TK above the surface, and get him onto something that floats. This tires him out and he would have drowned if his own Crest didn't glow.
Finally, this is a pretty small one, but Joe makes sure that everyone else gets across Death Course trapeze to safety, pushing Izzy away just as Piedmon walks up and turns him into a key chain. Izzy (and Tentomon) don't get away, but everyone else does!
The Japanese crest 'Seijitsu' doesn't have a direct English translation, but incorporates traits such as honesty, sincerity, reliability, and faithfulness. Digimon Adventure tends to treat it more in the reliability sense. In Digimon Adventure 02 when Iori (Cody) receives the corresponding digimental, he struggles with needing to break his honesty to tell a lie in order to be reliable and save his friends.
The awesomeness of Tai. After unsuccessfully forcing Agumon to evolve into an Ultimate, abandoning Sora due to his fear, having a Heroic BSOD, he finally grows a pair when things seem the most hopeless, has Agumon transform into a proper Ultimate level and kick the ass of Etemon, who has constantly been one step ahead of them the whole damn arc!
That entire episode is pure win. Starting with Ikkakumon's bombardment of the pyramid, the three-on-one fight between Ikkakumon, Togemon, and Garurumon against Etemon, Tai sticking it to both Etemon and Datamon, Etemon getting trapped under the electric fence by Birdramon, and of course the finale where Etemon gets fused with his Dark Network, starts consuming the entire desert around him, and then MetalGreymon kicks his ass.
And Tai's return to the Digital World: he manages to bring the entire team back together, making him The Messiah.
How T.K. single-handedly tricked Puppetmon, sabatoged his voodoo dolls that he was using against everyone, AND escaped all on his own. Oh yeah...and did we forget to mention T.K. is about an 8-9 year old kid...AWESOME!
Kari, Kari, Kari. Just Tai's baby sister and an adorable, Ill, Affirmative Action Girl, right? Well, say that when she, at all of eight years old, walks up towards WaruMonzaemon, ostensibly offering herself up as his first kill, but striding up there, looking for all the world like a queen.
Her first CMOA was when she, knowing exactly what would happen to her, gave herself up to Myotismon. She knew that no one would blame her if she ran and hid, but instead, she just walked up to Phantomon. "It's me you want." She was 8 years old, and willing to die to save her friends.
Kari gets so many awesome points in general for just freaking surviving the Digital World. That she returns on Digimon Adventure 02, all grown up and ready to do it all over again, can give one very happy feelings. She's all grown up.
Undoubtedly, the most awesome thing Mimi, whose motto is pretty much Everything's Better with Princesses, ever did was when the Garbemon threw their poop attack, and instead of running like everyone else did, she caught it in her hand and threw it back at them. Granted, she was wearing gloves and in the early stages of a Heroic BSOD, but damn if it wasn't cool. Took A Level In Bad Ass? You bet!
It was later made note of in season 2, not that anyone would know, cuz it was in Japanese. Even in the dub.
Wasn't it Sukamon and Chuumon they referenced in 02? Megaton Punch, bitch.
Who could forget the first Angewomon/Lady Devimon fight? Everything from cute li'l Hikari uttering "[Lady Devimon] looks like a witch" and cheering her on in the ennsuing catfight (pun not intended) to Tai and Izzy providing the exact commentary that came to everyone's mind. To wit, "I know I shouldn't be watching this but I can't turn away!"
LadyDevimon: You broke it!
MegaKabuterimon: Awww...send me the bill.
Gatomon/Angewomon gets one when she first digivolves to the Ultimate level, in a bout of Unstoppable Rage after Myotismon kills Wizardmon.
Arguably, all the Ultimates get one for their debut appearances.
How has Vamdemon/Myotismon's first appearance before the Chosen not been mentioned? The flying carriage, trailing darkness with him, the coffin skydive! This troper thinks that is the only villain entrance they have honestly never forgotten.
MagnaAngemon: After Piedmon had whupped on him and all the other Digimon — Mega or otherwise — Angemon Took a Level in Badass and changed to this Ultimate form and handed Piedmon his ass. He follows this up by sucking Piedmon into the Gate of Destiny.
He also saved two of the kids just in time from falling to their doom.
It can be argued that MagnaAngemon won so easily because he is an angel, and the natural enemy of the Dark Master Piedmon, but still.
Angemon's (Champion-level) first appearance was pretty awesome too. The thing that sort of got me interested in following the show, in fact.
Another thing from the final fight with Piedmon that counts is Mimi leading a Gondor Calls for Aid against Piedmon's army of Vilemon. She may have had trouble getting to the fight, but she sure made her entrance count big time.
The beatdown all the chosen Digimon hand to Piedmon afterwards also counts.
Including Myotismon who, at the moment in question, defeats Greymon almost immediately.
Said moment was particularly awesome due to how Dangerously Genre Savvy Myotismon proved to be about the techniques and surroundings of the battle. The two digimon are fighting near a river, Metal Greymon fires a Giga Blaster (which are missles), Myotismon counterattacks with Crimson Lightning (which is a red energy whip) and knocks the missles into the river, ending the fight completely unharmed! Damn.
Wizardmon. The guy is a walking Crowning Moment of Awesome. He was basically loyal to Gatomon all along, helping her when he suspected her of being a partner. He willingly went against Myotismon, declaring "How could I betray you when I was never on your side to begin with!" (a line this troper has never forgotten and has even used on occasion), and surviving two fatal attacks. When he attacks Myotismon from behind after the first attempt, Myotismon actually shows fear when he sees his assailant, something to even Angewomon couldn't achieve. His eventual Heroic Sacrifice paved the way for Gatomon's Moment.
After Gatomon realizes who she is, she stands up to and fights Myotismon.
Gatomon: If you believe in yourself, then dreams are real, and to make my dreams come true, I only have to do one thing: defeat you!
Heck, everything before Myotismon and company invading Tokyo counts, even the little details. Why? Because seven children, the oldest ones barely into adolescence, if that( the oldest was 12, and T.K, was 8!), completely vanished into a foreign realm where almost every enemy Digimon could have killed them. They didn't have previous information or past Chosens to aid them like the 02 clan did, their only source of protection was their inexperienced partners, and they had neither an easily-accessible way of returning home (until Izzy cracked the card code) nor a way of contacting their significant others to let them know they were alright. And despite all of their near-death experiences (including petrification and being swallowed by a whale), they all survived. You try to find seven random people in the Chosens' age range in your town that would be brave enough to duplicate that feat. Against their will. When Izzy said they were pioneers, you better believe he was right.
WarGreymon vs. Machinedramon. He immediately warp-digivolves, slices through the bad guy, and depowers back to the In-Training form of Koromon. After a few seconds of Machinedramon taunting him about how ineffective his attack was, Koromon reveals that he actually sliced him up pretty bad. Bye, Machinedramon.
On that note WarGreymon vs Metal Seadramon, he goes into rage mode when Whamon gets shot in the head becomes a tornado, deflecting the counter-attack and drilling straight through the inside out.
The immediate follow-up to Agumon and Gabumon's first time warp-evolving was a fantastic moment like this. The first thing they do is show off just how powerful they are as WarGreymon and MetalGarurumon by laying spectacularly into the previously unflinching VenomVamdemon and actually budging him, never mind knocking him over and freezing him; even if it didn't deal much damage in the long-term, it was truly an awesome sight and a fantastic way to introduce the true magnitude of the Ultimate level. What topped it off was the camera treatment of MetalGarurumon's first Macross Missile Massacre - quickly panning over all his missile ports loading and unfurling, then rapidly zooming out from the top as it all fired... yesssss.
How about Omegamon/Omnimon's first appearance in Digimon: The Movie? Beaten and broken, Wargreymon and Metalgarurumon get power from kids all around the world, and they digivolve together to form Omnimon, a huge badass White Knight with Grey Sword and Garuru Cannon. Omnimon then proceeds to casually destroy thousands of copies of the Mega-level Digimon Diaboromon (actually, probably over a million, as Izzy notes), just one of which was giving his previous forms massive difficulty. It was badass and perhaps the best introduction for any Digimon ever.
Say it with me now: "TRANSCENDENT SWORD!"
The dub does a really good job with the music in that scene alone. The moment it kicks in, you know awesome is about to ensue. The sub, on the other hand, is no less epic as it provides Ominous Latin Chanting during this whole sequence, and delivers the Curb-Stomp Battle in almost utter slience (aside from a few lines from characters and sound effects), making Omegamon's appearance looks much alike divine retribution.
Magnamon and Rapidmon's appearance near the end of the film.
During the fight against Diaboramon, Wargreymon's Dramon Slayers are torn off. So what does he do? CLOCK Diaboramon right in the jaw! No fancy attacks necessary, just a straight up punch to the face. Wargreymon is just that badass.
The AWESOME of any of the Digimon films, especially Bokura no War Game ("Our War Game", a reference to, well, WarGames). In addition to having a fairly obscene budget, it was animated by a person who studied under Hayao Miyazaki at one time, so that's why the animation should look familliar. At one point, Diablomon decides to launch a highly advanced nuclear missile, and, when Koushirou finds out, he realizes it could blow up anywhere in the world, in nine minutes. A DIGIMON movie has a movie plot about stopping NUCLEAR WAR. All the while, the whole world is reaching out to the heroes via e-mail. It is awesome beyond words.
The sheer AWESOMENESS when Greymon wrestles against the Parrotmon.
Bokura no War Game. Omegamon/Omnimon. That is all.
Who can forget the moment that created Omnimon? Children from all over the world helped to do so with their words of support, also making this a Crowning Moment of Heartwarming.
The entire Omnimon segment in both the dub and the sub.
Omnimon announcing his name in the dub is a moment alone.
Having watched both versions, this troper thinks the sub version must be mentioned since it worked quite differently to the dub, but nothing less epic: After the whole beatdown shown above, the next minute is still the chase between Omegamon and Diablomon but this time around, the background music is replaced by clock's beeps only, showing how pressurized the situation is.
Another thing that makes Bokura no War Game is so awesome is when you realise that it was major foreshadowing. How so? Well remember that the movie is in fact Canon (having been mentioned in series by two of the characters), and that during it, kids from all over the world were watching, including the protaganists of 02. Anyone remember what the requirements for becoming a digidestined in 01 and 02 were? It was by seeing a digimon. Now if the children watching had in fact amounted to, oh say, 50 million, you suddenly realise where they all came from during the final episode of 02. Chekhov's Gun indeed!
The whole movie is a Crowning Movie Of Awesome - there is a good reason why Encyclopedia Dramatica thinks of this movie as the best anime movie of them all
Well, of course. On top of stopping nuclear war, they save the freaking internet! That fact alone is reason for any self-respecting geek to watch it.
Greymon's first appearance in the movie, first Parrotmon NoSells Agumon's attacks and destroys the bridge above him, Tai and Kari (i mentioned they were there right?) and they get covered in rubble, phone's and lights around them go haywire, dust clears to reveal a Kaiju sized Greymon. Cue epic fight.
Greymon: I'm Greymon now.
Tai: You can be whoever you want, big guy.
That moment in the dub where, after waiting the whole time to hear it, Greymon finally goes into action and the dub theme plays full-blast.
He never gets enough love for it, but Piximon proves himself the single most badass character in the series by rescuing the kids from the assembled Dark Masters, then single-handedly holding them off, buying time for the children to escape. He knows he's going to die, but hell if that's going to stop him. Just to emphasize: that little pink Digimon took on four of the baddest Digimon around, all of which were a higher level than him - and all of whom gave the heroes trouble, even when they were at their best and fighting just one - and stalled them long enough for the kids to escape. Unfortunate that we never got to see the actual fight.
Probably because he actually lasted all of 5 seconds.
Gomamon & Sora's argument in episode 52, whilst ultimately leading to Piedmon capturing both of them, is for both of them. Why? Sora's telling Gomamon to go with TK & Kari so that he doesn't get hurt since he can't digivolve out of his Rookie form without the captured Joe, and Gomamon refuses to leave Sora for the opposite reason, as Garudamon has already been captured.
On top of that, when Piedmon catches up to them, gloating about how he wants a full-set of DigiDestined keychains, Gomamon throws himself at Piedmon & snatches Matt from him. Little dude's got guts.
In Episode 43, Mimi makes four graves for the four Digimon that have died for them. She breaks down, saying she's had enough. Tai snaps her out of it, getting angry and saying, "This is war, Mimi! Sometimes people we like get hurt. So deal with it!" He's really demonstrating courage there, even if Matt thinks he was in fault.
Warp Digivolutions from the Digimon AdventurePlayStation Portable game, finally. Although Agumon and Gabumon's Warp Digivolutions are great to witness as well, the inclusion of the Warp Digivolutions for Biyomon, Tentomon, Palmon, Gomamon, Patamon, and Gatomonnote all of who Digivolve into WarGreymon, MetalGarurumon, Hououmon/Phoenixmon, HerculesKabuterimon, Rosemon, Vikemon, Seraphimon, and Ophanimon, respectively are quite terrific sights to behold. The sequences are even better when one takes in account that some of the fandom has known about the aforementioned Digimon's Mega forms for years, yet only WarGreymon and MetalGarurumon received anime animations of their Digivolution sequences in Digimon Adventure.
