* It's possible to easily catch Necrozma with virtually any type of Pokéball when you find it in Mount Lanakilla after clearing Mina's trial — even a normal plain Pokéball. Meaning, at this point, Necrozma's catch rate is 255. While this seems anti-climatic to some players, think about it; it's already really weak when you found it, and even if you shared some strength to it through your Z-Ring, it's strong enough to fight, but it's too weak to fight back capture through a Pokéball. Necrozma's strength is not fully recovered, and in a way, Necrozma's injuries from your battle against it as Ultra Necrozma isn't completely healed. And with Necrozma's interest to the player's Z-Ring, Necrozma accepted capture either way so Necrozma could be healed in time.

* So Festival Plaza is actually a virtual-reality computer simulation, as we see when Sophocles restarts the system after Team Rainbow Rocket takes over. Okay. But what about all the things you can do in Festival Plaza that have real effects outside? It makes sense that trading Pokémon would be possible, as it's already well-established in the series that Pokémon can be stored and transported as data.[[note]]In-universe, I mean — in the real world they're always data, no question about that.[[/note]] Battling makes sense too, as battling never occurs in Festival Plaza except with online/facility rules, which happen to be exactly the limitations you'd expect a simulated battle to have.[[note]]As in, it doesn't actually affect anything outside the battle — Pokémon leave the battle with their HP and status exactly as it was before the battle, no experience is gained, Bag items are inaccessible, etc.[[/note]] What doesn't make sense is all the facilities, which ''do'' have those types of lasting effects. Things like the lottery/item shops can be HandWaved as just having the items you win/buy sent to you instead of literally obtaining them from the shops, like in real life. Dyeing your clothes, that you're either wearing or (presumably, since you can change at any store) carrying in your Bag, doesn't make much sense. Neither does letting your Pokémon exercise and gain actual [=EVs=], or gaining levels at the Rare Kitchen, etc. If a VR simulation really ''can'' do all those things in the Pokémon universe, there's a ''lot'' of untapped potential there.

* When you enter Ultra Ruin, Guzzlord's territory, talking to the one NPC, you learn that this alternate world was ravaged instead by a devastating power plant meltdown, and Guzzlord is simply cleaning up the mess humanity left it. One does have to wonder what kind of power source was being used to result in such a disaster that the people of that world even tried to [[MyGreatestFailure sweep that power plant's existence under the rug.]].
* Listen closely to the remix of Lysandre's theme. In the original, you can hear a gun cocking near the start, and there is wailing throughout the theme. In the Rainbow Rocket version, there's no gun cocking and no wailing... because ''this'' Lysandre has already used his weapon, and there's '''''no one left to wail'''''.

* It's possible to catch Necrozma with other types of Pokéballs when you found it in Mount Lanakilla after clearing Mina's trial, even a normal plain Pokéball. Meaning, at this point, Necrozma's catch rate is 255. While this seems anti-climatic to some players, think about it, it's already really weak when you found it and even if you shared some strength to it through your Z-Ring, it's strong enough to fight, but it's weak to fight back capture through a Pokéball. Necrozma's strength is not fully recovered and in a way, Necrozma's injuries from your battle against it as Ultra Necrozma isn't completely healed. And with Necrozma's interest to the player's Z-Ring, Necrozma accepted capture either way so Necrozma could be healed in time.

* Maxie and Archie can't use Primal Groudon/Kyogre when you battle them, not only because they come from the Gen 3 timeline (where Primal Reversion did not exist) but also because in those games, Maxie took the Blue Orb and Archie the Red Orb; the orb they took would not have triggered Primal Reversion for their respective legendary.
** Their legendaries also didn't have their signature moves (Precipice Blades for Groudon and Origin Pulse for Kyogre), further supporting the fact, as those moves didn't exist back in Gen 3.
** Archie has no idea how to deal with Primal Groudon if you use it against him. The non-Mega timeline lacked Primal Reversions, so he had no way of knowing them, let alone that Desolate Land, Primal Groudon's ability, makes it immune to Water-type moves.

** In relation to this, he is also perhaps the most stable and reasonable of the villain team leaders, not subject to the odd logic/fanaticism of Maxie/Archie, the nihilism of Lysandre/Cyrus, the madness of Ghetsis, and so on. He's a ambitious criminal and charismatic leader, but one who is also quite willing to cut his losses when things don't go well, rather than throw a fit, kill himself, etc.
* The sun is the brightest at day and the moon shines only at night. It fits the parallel of the Ultra Recon Squad's differing motivations in ''Ultra Sun'' and ''Ultra Moon'', with some symbolism in it. In ''Ultra Sun'' they want to stop Necrozma from taking Alola's light, like the sun that shines and provides energy to all. In ''Ultra Moon'', they want to make use of Necrozma's power to restore the light of their world. Like the moon shining in the dark.
** Additionally, day time is generally considered to be a time where Children are mostly active and the night is when children usually sleeps. Reflecting to how Dulse and Zossie, the younger duo of the Ultra Recon Squad, play a role in the main scenario of ''Ultra Sun'', but not in ''Ultra Moon''. The same applies vice versa with Phyco and Soliera who play a role in the story of ''Ultra Moon'', but not in ''Ultra Sun''.
* Why is Po Town full of Totem Stickers when it seems unlikely that Nanu, Acerola or any other Trial Captain/Kahuna would put them there? Because, as was mentioned when they first appeared on Melemele Island, Team Skull like finding and stealing Totem Stickers — but they don't throw them away, they put them in Po Town, maybe as trophies or to lure in trainers.

* Because most of the beginning dialogue of the game that foreshadows her Abusive Parents actions is exactly the same as in Sun and Moon, and then the reveal that she didn't treat them as badly as in Sun and Moon may come as an AssPull for some people because it leaves the question of why Lillie and Gladion were so angsty. But considering that the disappearance of Mohn came to the forefront of the main story, they now have other things to be angsty about besides their mother's parenting. Because realistically, seeing your sole parent become bad at parenting was enough, but because you lost your loved one to an Ultra Wormhole thus causing your sole parent's bad parenting, you got other things to be so angsty about.

* The Ruins of Conflict are the only ruins with no stone puzzle. Why? Well, Tapu Koko loves a fight, after all- therefore it made its ruins completely accessible so challengers can easily get to it.

* Lusamine accept the fact that Mohn completely lost his memory about his family and Aether Foundation, along with not pressing the issue further, might not only for his own good but hers also. If Mohn ever got aware about his wife's abusive behavior towards their children (however downplayed it is compared to the vanilla ''Sun'' and ''Moon'') after his disappearance and the grievance his children suffered because of it, he will almost certainly never forgive her, no matter whatever excuse she comes out with.

** Lysandre was even worse. [[TheEndOfTheWorldAsWeKnowIt He possibly destroyed his universe, leaving only Team Flare and himself as the survivors]]. Worst of all, unlike the other universes who have a chance of salvation, there are practically no life forms, humans, Pokémon, or plants, left in Lysandre's world apart from Team Flare, making him the only villain to come from a world with a hopeless DownerEnding. Heck, without a functioning ecosystem, even Team Flare likely won't last very long. Unless the weapon made them incapable of dying, [[WhoWantsToLiveForever which might be even worse]].

** It's also never said how long they were in the Ultra Universe, it's quite possible in their original worlds the population had enough time to recover. In Ghetsis's case, however, he didn't exactly get away scott free:

### His knowledge of other dimensions and his lust for power isn't a good mix. It's quite clear he was planning on upgrading to a dimensional conqueror [[TheManBehindTheMan "Man behind the Man"]] using Giovanni as a puppet. So even if he gets back to Unova power intact, he lives with the knowledge that there are other worlds he doesn't control, and that is sure to enrage him and possibly set up his future defeat.

** Albeit only one world is known to have lost its light (when Necrozma invaded Alola it was repelled, and at some point afterward it was imprisoned by the people of Ultra Megalopolis), and said world (Ultra Megalopolis) survived (apparently when Necrozma steals light, it doesn't literally steal all light and warmth, in the games light is spoken of often in a more metaphorical sense).

* Listen closely to the remix of Lysandre's theme. In the original, you can hear a gun cocking near the start, and there is wailing throughout the theme. In the Rainbow Rocket version, there's no gun cocking and no wailing... because ''this'' Lysandre has already used his weapon, and there's ''no one left to wail''.

** Yet at the same time, unlike Lusamine, the protagonist had the Ultra Recon Squad who are aware of Ultra Beast in general and would have likely warned the protagonist about them.

* So Festival Plaza is actually a virtual-reality computer simulation, as we see when Sophocles restarts the system after Team Rainbow Rocket takes over. Okay. But what about all the things you can do in Festival Plaza that have real effects outside? It makes sense that trading Pokémon would be possible, as it's already well-established the series that Pokémon can be stored and transported as data.[[note]]In-universe, I mean—in the real world they're always data, no question about that.[[/note]] Battling makes sense too, as battling never occurs in Festival Plaza except with online/facility rules, which happen to be exactly the limitations you'd expect a simulated battle to have.[[note]]As in, it doesn't actually affect anything outside the battle—Pokémon leave the battle with their HP and status exactly as it was before the battle, no experience is gained, Bag items are inaccessible, etc.[[/note]] What doesn't make sense is all the facilities, which ''do'' have those types of lasting effects. Things like the lottery/item shops can be HandWaved as just having the items you win/buy sent to you instead of literally obtaining them from the shops, like in real life. Dyeing your clothes, that you're either wearing or (presumably, since you can change at any store) carrying in your Bag, doesn't make much sense. Neither does letting your Pokémon exercise and gain actual EV's, or gaining levels at the Rare Kitchen, etc. If a VR simulation really ''can'' do all those things in the Pokémon universe, there's a ''lot'' of untapped potential there.

* A minor one. Mohn's outfit is a white shirt with an orange scarf tie in the original games, which gets changed to green in ''Ultra Sun and Ultra Moon''. Green, in heraldry, symbolizes hope. In the original games, Mohn's situation is left ambiguous to whether he'll see Lusamine and his family again, while in ''Ultra Sun and Ultra Moon'', in post-game, Mohn, despite still being an amnesiac, is able to reunite with his family with a hope that they'd meet again. After all that happened to them after Mohn disappeared into the ultra warp hole, [[EarnYourHappyEnding they're finding happiness again]].

* This game confirms that the place where Nihilego reside is called 'Ultra Deep Sea'. It's not a cave, it's a strange alien ''ocean'' where Nihilego are commonly found. Which explains why Lillie mentions that it's "hard to breathe" when you visit it in ''Sun and Moon''--it's full of some sort of oxygenated liquid that, while breathable, the pressure of the ocean and difficulty in trying to breathe liquid makes it an uncomfortable experience.

* This game introduces several new Bug-type Totem Pokemon — in fact, between both versions of Alola, the only Alolan Bug-type who is ''not'' a Totem is Golisopod, who would make a terrible Totem due to [[AntiClimaxBoss its "Emergency Exit" ability]]. Maybe ''that'' is why Guzma never made it as a Captain.

* In true Pokémon fashion, you get Zygarde post-game. But the game ''wants'' you to see it stirring, as there's a cutscene in the end credits of 50% Zygarde waking up in Resolution Cave. It also works because the player's next opponents are perhaps the most dangerous — Rainbow Rocket, who have the combined power to ruin the whole world. Of course Zygarde would be [[IncrediblyLamePun on guard]] for such an event happening.

It also works because the player's next opponents are perhaps the most dangerous - Rainbow Rocket, who have the combined power to ruin the whole world. Of course Zygarde would be [[IncrediblyLamePun on guard]] for such an event happening.
* So why do some of the villains seem so blase at being defeated? [[TheBadGuyWins They won in their timelines]]. So it's no real biggie - they can still go back to where they won.
** It's implied most of the villains "successes" ended with them ''dying'' (Maxie was inches away from falling into lava). Thus, this could in turn be a subtle FaceDeathWithDignity if they get sent right back to the point of their death.
* When Lusamine goes to confront Necrozma, she brings Guzma along with her. At first, it might seem like she's just using him as an excuse to go after Necrozma after the main character proves she's not strong enough to fight it by herself, but it's actually a pretty sound tactical move. If you're fighting a powerful psychic type, why not bring one of the best bug type trainers in Alola?

* While most trainers got a buff, if anything Team Skull got a ''nerf''. They're still worthless and are an annoyance at best. This is actually GameplayAndStoryIntegration - InUniverse nobody takes them seriously.

* At first glance, Giovanni being the leader of all the Villainous Team Leaders seems like a wag to Genwunners, but actually he would have the best capability to lead them all. Sure, in his game his plans were tame compared to the other bosses, but he is also the best leader overall. Archie and Maxie are leaders of known fanatic/terrorist group, Cyrus had to operate in the shadows, and Ghetsis and Lysandre were public faces, but had to hide the true intentions of their respective Teams. Giovanni not only lead a known criminal group for years, but also functioned as a Gym Leader, a respected individual in the Pokemon world and thus one under intense public scrutiny. Yet it seems NO ONE made the connection over the years that the leader of the Viridian Gym was also the head of Team Rocket. Giovanni is the only boss who can project a good public image AND lead a group participating in criminal activities.
** In relation to this he is also perhaps the most stable and reasonable of the villain team leaders, not subject to the odd logic/fanaticism of Maxie/Archie, the nihilism of Lysandre/Cyrus, the madness of Ghetsis and so on. He's a ambitious criminal and charismatic leader, but one who is also quite willing to cut his losses when things don't go well, rather than throw a fit, kill himself, etc.

Because, as was mentioned when they first appeared on Melemele Island, Team Skull like finding and stealing Totem Stickers- but they don't throw them away, they put them in Po Town, maybe as trophies or to lure in trainers.

* Lusamine's Pokemon collection and anger at her children still makes sense despite her personality shift- she's still devastated by Mohn's disappearance, so she hangs onto the Pokemon so they won't leave her. And she's angry at her children because losing one of her loved ones was enough- then both her children ran away.
* Because most of the beginning dialogue of the game that foreshadows her Abusive Parents actions is exactly the same as in Sun and Moon, and then the reveal that she didn't treat them as badly as in Sun and Moon may come as an AssPull for some people because it leaves the question of why Lillie and Gladion were so angsty. But considering that the disappearance of Mohn came to the forefront of the main story, they now have other things to be angsty about besides their mother's parenting. Because realistically, seeing your sole parent become bad at parenting was enough but because you lost your loved one to an Ultra Wormhole thus causing your sole parent's bad parenting, you got other things to be so angsty about.

** Not only that, but assuming that Ghetsis didn't get mindwiped, he now knows about the other regions with more powerful pokemon, Z-moves, and Mega Evolution. Team RR, as well as the player, have given him more footholds to maintain and gain even more power...

** Cyrus more or less failed. When you first fight him, he says that a massive shadow (most likely Giratina) consumed him while he was remaking the world, and it is established that he cannot use the full power necessary to remake the world with a captured Dialga or Palkia due to power limiters within poke balls (which is why he used the red chain).
** Archie's and Maxie's dialogue implies their plans also got them ultimately killed, and Lysandre's claim of being "swallowed by a bright light" might mean that his weapon didn't discriminate (There was really no reason given why it ''would''). His Pokémon still being alive also brings into question whether it even worked in the first place. No such luck for Ghetsis though.

** It's also never said how long they were in the Ultra Universe, it's quite possible in their original worlds the population had enough time to recover. In Ghetsis's case however he didn't exactly get away scott free:

### His knowledge of other dimensions and his lust for power isn't a good mix. It's quite clear he was planning on upgrading to a dimensional conqueror [[TheManBehindTheMan "Man behind the Man"]] using Giovanni as a puppet. So even if he gets back to Unova power intact, he lives with the knowledge that there are other worlds he doesn't control and that is sure to enrage him and possibly set up his future defeat.
### Lastly, his Pokémon are all fainted in addition to all the other Team leaders, so all it takes is for one Trainer to stop them once they return assuming they aren't teleported to safe territory.

* [[EldritchAbomination Necrozma]] was originally a Pokemon whose [[NiceJobBreakingItHero light was stolen by ancient people]]. Due to lacking the light, Necrozma is forced to hop from dimension to dimension, draining the light from it before going to another universe to drain. Meaning [[PersonOfMassDestruction Necrozma]] unwillingly caused [[OmnicidalManiac several]] [[MikeNelsonDestroyerOfWorlds mass-extinctions]], [[ApocalypseHow dooming civilizations]] and rendering universes into a [[TheEndOfTheWorldAsWeKnowIt Big]] [[DarkWorld Freeze]] type event. In other words, DarkFantasy and '''''CosmicHorrorStory'''''.
** Albeit only one world is known to have lost its light (when Necrozma invaded Alola it was repelled, and at some point afterward it was imprisoned by the people of Ultra Megalopolis), and said world (Ultra Megalopolis) survived (apparently when Necrozma steals light it doesn't literally steal all light and warmth, in the games light is spoken of often in a more metaphorical sense).

* Listen closely to the remix of Lysandre's theme. In the original, you can hear a gun cocking near the start, and there is wailing throughout the theme. In the Rainbow Rocket version, there's no gun cocking and no wailing... because ''this'' Lysandre has already used his weapon, and there's ''[[KillEmAll no one left to wail]]''.

* Every starter has an advantage against the game's ClimaxBoss. Ultra Necrozma is Psychic/Dragon type. Decidueye's Ghost type and Incineroar's Dark type beat Necrozma's Psychic type, while Primarina's Fairy type beats Necrozma's Dragon type.
** Ultra Necrozma's typing is also part of the "It All Comes Together" theme of the Seventh Gen, as both of its types are the types once considered overpowered and new types were introduced into the game to counter them. (Dark for Psychic and Fairy for Dragon)

* This game introduces several new Bug-type Totem Pokemon- in fact, between both versions of Alola, the only Alolan Bug-type who is ''not'' a Totem is Golisopod, who would make a terrible Totem due to [[AntiClimaxBoss its Emergency Exit ability]]. Maybe ''that'' is why Guzma never made it as a Captain.

** It's also never said how long they were in the Ultra Universe, it's quite possible in their original worlds the population had enough time to recover. In Ghetsis's case however he didn't exactly get away scott free. 1: his defeat by the protagonist gave him his original villainous breakdown which is sure to make him less in control once he returns back in his world which Colress speculates as a possibility. 2: his knowledge of other dimensions and his lust for power isn't a good mix. it's quite clear he was planning on upgrading to a dimensional conqueror Man behind the Man using Giovanni as a puppet. So even if he gets back to Unova power intact, he lives with the knowledge that there are other worlds he doesn't control and that is sure to enrage him and possibly set up his future defeat. 3 Lastly his pokemon are all fainted in addition to all the other Team leaders, so all it takes is for one Trainer to stop them once they return assuming they aren't teleported to safe territory.

* When you enter Ultra Ruin, Guzzlord's territory, there is a reason why it is so unsettling: It is a ruins of [[RuinsOfAModernAge Hau'oli City]] that was wrecked and gorged by [[EldritchAbomination Guzzlord]] whose [[BigEater extreme gluttony]] destroyed it. The man in the entrance of the Ultra Ruins talks about so many people leaving for another dimension. Implications? Guzzlord murdered so many people and Pokemon it turned this world into something out of ''VideoGame/SpecOpsTheLine'', only if [[TragicHero Captain Martin Walker]] and [[FallenHero Colonel Konrad]] were replaced with Pokemon.\\
Horrible as it sounds, this world is probably a parallel timeline where Lusamine succeeded in unleashing Ultra Beasts into the world, [[HoistByHisOwnPetard but probably didn't survive long enough to be recruited by Giovanni. There could be people who were unable to escape in time and forced to be trapped in this ruins. And let's not forget that Ultra Beasts and Guzzlord-ilk probably roaming around like violent animals and that the Pokemon League possibly used a nuclear weapon judging from its map. [[WhatDoYouMeanItsForKids You know, for kids!]]\\
Want to make it darker? It is possible that the other Ultra Space worlds are worlds where the Ultra Beasts roamed, originate and overrun with their ilk, destroying civilizations and killing ecosystems. It replaces with theirs judging by the AlienSky, AlienKudzu and AlienGeometries that are growing in their abodes.]]\\
Conclusion, the Pokemon World is a CosmicHorrorStory similar to ''Franchise/ShinMegamiTensei'' and Creator/HPLovecraft, only kiddiefied.
** For added Fridge Horror, We never [[NothingIsScarier truly see Guzzlord's native Ultra Space.]]
** A lot of this is almost immediately dispelled, however, by talking to the one NPC and learning that rather than an EldritchAbomination assault, this alternate world was ravaged instead by a devastating power plant meltdown. Guzzlord is simply cleaning up the mess humanity left it, though one does have to wonder what kind of power source was being used to result in such a disaster that the people of that world even tried to [[MyGreatestFailure sweep that power plant's existence under the rug.]].
* Minior's Meteor Form Pokédex entry in ''Ultra Sun'' states that "It lives in the ozone layer, where it becomes food for stronger Pokémon". As established in ''Omega Ruby and Alpha Sapphire'', Rayquaza likes to snake on meteors. So, either Rayquaza natural eat Minior, OR there's something else in the ozone layer. SM079 of the anime also showed Rayquaza near a meteor shower of Minior as well.
