!!Original Games
* Groudon and Kyogre's [[http://www.youtube.com/watch?v=uwJViCjDkLA epic]] [[http://www.youtube.com/watch?v=IxbbJfpuNjA battle]] in ''Pokémon Emerald''. And more importantly, Rayquaza, [[spoiler:who flies to Sootopolis after you encounter it at the Sky Pillar. Once you arrive there and witness Groudon and Kyogre again, Rayquaza comes out, flies through the clouds, descends with a trail of green light cloaking it, and swoops down to Groudon and Kyogre. With one mighty roar, it sends them both away, and departs, returning the weather to normal.]] How intense is that?
** And the '''music''' (specifically, [[http://www.youtube.com/watch?v=rrdWwqlNwRM "Heavy Rain"]] and [[http://www.youtube.com/watch?v=KcLNMZPF2DA "Rayquaza's Descent!"]] accompany the scenes), which could be considered CrowningMusicOfAwesome in their own right.
* Earning [[http://bulbapedia.bulbagarden.net/wiki/Ornament#Awards the Gold Shield ornament]] after winning ''100'' straight battles in the Battle Tower definitely qualifies as one for the player and his/her Pokémon.
** Or managing to get the gold symbols in the Battle Frontier, especially with all [[TheComputerIsACheatingBastard the crap]] they put you through.

!!Omega Ruby and Alpha Sapphire
* In the original games, Groudon and Kyogre's special abilities automatically summoned permanent sun or rain to the battlefield. Unfortunately, a {{Nerf}} in Gen VI changed the abilities to just an automatic Sunny Day or Rain Dance, ending their effects after five turns. Then comes ''Omega Ruby'' and ''Alpha Sapphire'', and the introduction of Groudon and Kyogre's Primal forms, who have two new abilities: Desolate Land and Primordial Sea which, [[AwesomeMcCoolName besides sounding really badass]], came with a few new effects:
** Made the sun/rain permanent again as long as Primal Groudon or Primal Kyogre are present.
** Once one of the abilities is activated, the weather cannot be changed by a normal Rain Dance or Sunny Day.
** And most importantly, ''[[NoSell completely negates water]]'' (if Desolate Land is in effect) ''[[NoSell or fire]]'' (if Primordial Sea is in effect) ''type attacks used against Groudon or Kyogre''. Thought you could one-shot Primal Groudon with a [[KillItWithWater water type attack]] thanks to its [[ForMassiveDamage 4x weakness]]? '''[[SubvertedTrope NOPE]]'''.
** It gets better. Mega Rayquaza's ability, '''Delta Stream''', lessens its weaknesses as Delta Stream negates any super-effectiveness against Flying-types, thus taking its 4x weakness against Ice to only 2x and negating its Rock weakness altogether, making it much less easily taken out by Groudon or Kyogre.
* Mega Latias and Mega Latios can be ridden as mounts, allowing you to fly across nearly all of Hoenn, including to the mysterious clouds shown in the region's official art and the various small islands dotted around the region. For what purpose, exactly? To find every non-event legendary Pokémon that wasn't in the original Ruby and Sapphire or X and Y.
* In a meta-moment, for ''all the flack'' people gave Generation III, the [[http://www.siliconera.com/2014/09/20/fans-lining-pokemon-omega-ruby-alpha-sappire/ lines]] in Japan finally [[VindicatedByHistory put the case to rest]]: the fanbase ''loves'' Hoenn. These are just lines for ''pre-orders'' and they span from Sendai, Nagoya, Sapporo, Yokohama, Fukuoka, and Tokyo Bay. [[AwesomeMusic/{{Pokemon}} Let the trumpets sound.]]
* Wally's already badass by time you make it to Victory Road, but the remake highlights his major improvement; you fight him in a field of flowers at the end of Victory Road, he gets a slightly tweaked introduction for the fight and the [[https://www.youtube.com/watch?v=5-wYGBi_JyA Music]] is redone from the generic trainer battle music that was in the original fight.
** Starting with Lavaridge Gym, his name will always be on the gym statue before you even get there. Meaning he keeps beating the gyms before you do like ''[[VideoGame/PokemonRedAndBlue Blue]]''! Pretty awesome considering the last gym you saw him, he only had one level 17 Ralts. Even if excusing it on the player getting distracted by Aqua or Magma, the feat is still amazing.
** During Episode Delta, [[spoiler: his keystone gets stolen. His initial response isn't to break down but adamantly states his priority is to protect his family, lack of Mega Evolution be damned]].
** [[spoiler: His post-game team (after you beat a Chatellaine on a Super line) then takes it further. His team levels range from high seventies, with Gallade at 81. Furthermore, a large portion of them use sets actual competitors use. Wally could essentially pick a fight with the likes of ''Steven or Red''.]]
* The newly-revealed Delta Episode, which apparently involves [[spoiler:riding Rayquaza into space to fight off an asteroid, which is also Deoxys - and from the details revealed, there are links to the [[VideoGame/PokemonXAndY war in Kalos]] from 3,000 years ago.]] This is awesome for two reasons:
** Firstly, just re-read that description. [[spoiler:'''Riding Mega Rayquaza into SPACE!''']]
** Secondly, [[UrbanLegendOfZelda there used to be rumours]] that [[spoiler:it was possible to go into space to get Deoxys and Jirachi in the original games. [[AscendedFanon Game Freak took one of the most-parodied rumours in the entire franchise and ran with it]].]]
* [[https://www.youtube.com/watch?v=Eju1zieC5rM There's an animated trailer]] similar to the one released for VideoGame/PokemonBlackAndWhite2.
* The game's opening. [[MythologyGag It begins with the EXACT "Welcome to the World of Pokémon" sequence from the original GBA games]]... only for the camera to slowly pan out and reveal this to be an in-universe image on the player character's Pokénav... and then you get a sweeping view of the Hoenn countryside, complete with various Pokémon, as the moving truck travels to Littleroot. The best part though, is how the music transitions ''seamlessly'' from the original GBA tune to an orchestrated remix during the RevealShot.
* Previously in Contests, if you filled the audience's excitement meter, you'd simply get a large point bonus and be told that [[ExactlyWhatItSaysOnTheTin the crowd is really excited]]. Now? Your Pokémon does a LimitBreak style move, some of which look ''really'' {{Badass}}. And if your Pokémon can Mega Evolve, it gets even better.
* The buildup to the battle with the version legendary. Like the originals, the battle is within the Cave of Origin, however, when you get to the place where you fought the cover legendary originally, you have to ''ride the version legendary's back'' with the help of a suit created by the version's villain team and the orb of the opposing version. Then, when you get to the place where the energy for Primal Reversion is, you jump off and watch as the legendary undergoes Primal Reversion and towers over you as it challenges you.
* On a meta level, [[GameBreaker Mega Rayquaza]] is ''so'' powerful that Website/{{Smogon}} wound up ''[[UpToEleven banning it from the uber tier.]]'' They had to create a new tier known as "Anything Goes" just to hold this legendary beast.
** For reference, the Uber Tier wasn't even entirely real until then. It was basically "anything goes" given a name, for things that were too powerful for other tiers. Mega Rayquaza basically broke the Smogon tiers and topped ''that''.
* In the French translation of the game, upon challenging Brawly, he actually says (in French) "I discovered the secret of the true power by [[LetsPlay/TwitchPlaysPokemon staring at a Helix Fossil for days and days]]."
* The credits are really cool as well as a CrowningMomentOfHeartwarming, showing you not only moments throughout your adventure but also what Pokémon you were using at that time, even during some more obscure moments. Then [[TheStinger after the credits]] [[spoiler: you and May/Brendan arrive at the pond where you first battled and they challenge you to one final battle, this time showing that they finally were able to obtain a Mega Evolution]].
* Game Freak deciding to screw gender norms and have Brendan [[http://i.imgur.com/TZ4JUqc.png have a thing for plush Pokémon dolls]] (even if he is a bit embarassed by it) is a great reminder that not all boys are going to manly men and not all girls are going to be pink dresses. Emphasized further that ''Wally'' the one rival character from this game everyone had treated in the past as the [[NiceGuy sensitive guy]], ends up being far more {{Badass}} at the end than the {{Tsundere}} and a bit of dick rival, Brendan.
* Zinnia destroying the device for transporting the meteor to another dimension, saving the Pokémon world of the first five generations from a fate it could not have prevented.
