** Giratina in ''Diamond and Pearl'' is a contrast to its immediate predecessor legendary Rayquaza. Both are the third members of their own group who act as its leader, but unlike the benevolent Rayquaza, Giratina is more malevolent and destructive. Whereas Giratina can take two forms (in ''Platinum'') including its Altered Forme and Origin Form through the Distortion World or giving it a Griseous Orb, Rayquaza (in ''Omega Ruby and Alpha Sapphire'') can only achieve its true form through Mega Evolution.

** The Pokémon of Myth trio (Dialga, Palkia and Giratina) heavily contrasts to the super-ancient Pokémon trio (Kyogre, Groudon and Rayquaza) from ''Ruby and Sapphire''. The super-ancient Pokémon represents the aspects of Earth including oceans, continents and the sky. The Pokémon of Myth, on the other hand, represents the aspects of universe and reality including time, space and anti-matter.

* ContrastingSequelAntagonist: Giratina in ''Legends: Arceus'' is this to Eternatus from ''Sword and Shield''. Both are [[DragonsAreDemonic ominous]]-[[{{Dracolich}} looking]] legendary dragons who are responsible for a phenomenon happening in their region (Dynamaxing for Eternatus, space-time distortions for Giratina), but while Eternatus was an alien [[AmbiguouslyEvil that didn't seem to be acting out of malice]], Giratina is of divine origin and part of a BigBadDuumvirate with Volo to get revenge on Arceus for punishing it.

** Although obscure now due to the content being DummiedOut, the [[https://tcrf.net/images/5/5c/PKMN_DPPT_Arceus_Flute.ogg Azure Flute]] and [[https://tcrf.net/images/8/8b/PKMN_DPPT_Arceus_Room.ogg Hall of Origin]] originally had unique themes, serving as variants of the intro and menu music of ''Pokémon Diamond and Pearl''.

* BreakoutCharacter: Despite being a Mythical whose original planned event was left DummiedOut, Arceus has gone down as one of the most popular and iconic Legendaries in the franchise due to its position of the TopGod in the lore, even getting [[VideoGame/PokemonLegendsArceus an entire game]] centred around it.

* OlympusMons: Manaphy is considered one, but Phione's status as a Legendary or Mythical Pokémon is subject to FlipFlopOfGod (though it's still banned from official tournaments and the like).

* {{Foil}}: Cresselia is a bringer of sweet dreams with a defensive playstyle, while Darkrai is a bringer of nightmares with an offensive playstyle. Cresselia has a set gender while Darkrai is genderless. Darkrai tends to be event-exclusive while Cresselia can be obtained without such methods. As of July 14th 2016, this also extends to their appearances in ''VideoGame/PokkenTournament'': Cresselia is an Assist Pokémon who can use Lunar Dance to help you out [[DeathOrGloryAttack once per round]] while Darkrai is a playable fighter. Darkrai’s NightmareFuel inducer with an offensive playstyle to Cresselia's SugarWiki/SweetDreamsFuel inducer with a defensive one. Oddly enough, Darkrai doesn't have a gender in the main games (in the anime and spin-offs it's a male) while Cresselia is [[OneGenderRace always female]]. Their signature move in ''Pokémon Legends: Arceus'' are also polar opposite of each other: Cresselia's Lunar Blessing heal herself and get rid of status condition while Darkrai's Dark Void inflict the Drowsy status and allow him to deal more damage by lowering the target’s defensive stats.

* ArtisticLicensePhysics: WordOfGod claims Giratina controls antimatter, but it somehow avoids being annihilated instantly upon entering the regular world. Ditto for Cyrus, Cynthia, and the PlayerCharacter in ''Platinum'' since they're presumably made of regular matter.

* CuteButCacophonic: Its Land Forme's cry is absolutely ear-grating.

* ArtisticLicensePhysics: WordOfGod certainly ''claims'' Giratina controls antimatter, but if that were true, it would be annihilated instantly upon entering the regular world. Ditto for [[spoiler: Cyrus, Cynthia, and the PlayerCharacter in ''Platinum'']] Plus, its abilities [[spoiler: and home dimension]] make it more fitting to be the embodiment of ''gravity'' instead.

* RockThemeNaming: The "Dia" in Dialga's name is derived from ''diamond'', while Palkia's contains ''paru'', the Japanese spelling of ''pearl''. Giratina's name appears to be a combination of ''girasol'' and ''platina'', referencing its red and gray color scheme.

* FinalBoss:
** Dialga serves as the final boss of ''Videogame/PokemonMysteryDungeonExplorers''.
** Origin Dialga or Origin Palkia serves as the final boss in ''VideoGame/PokemonLegendsArceus'' depending on if you choose to side with the Pearl Clan or Diamond Clan, respectively.

* FinalBoss: Arceus is the last boss of the CoOpMultiplayer story in ''[[VideoGame/PokemonRanger Pokémon Ranger: Guardian Signs]]''.

* TrueFinalBoss: It is the true final opponent of its namesake game ''VideoGame/PokemonLegendsArceus'', where you battle it at the end of the final Mission after catching every non-Mythical Pokémon in the game.

* AscendedExtra: After getting special treatment as a FakeUltimateMook in ''[[VideoGame/PokemonDiamondAndPearl Diamond and Pearl]]'', and receiving five alternate forms in ''Platinum'', Rotom was largely forgotten in terms of exposure in the following two generations. Come ''[[VideoGame/PokemonSunAndMoon Sun and Moon]]'', and its presence was drastically heightened by becoming a FairyCompanion for the player. ''[[VideoGame/PokemonSwordAndShield Sword and Shield]]'' followed suit by making Rotom-empowered devices commonplace for all trainers in the Galar region.

[[folder:Creation Trio: Dialga, Palkia, and Giratina]]

* DiscOneNuke: If you have an Event Arceus and trade it over in ''[[VideoGame/PokemonGoldAndSilver HeartGold and SoulSilver]], then visit the ruins, it will trigger the Sinjoh Ruins event where it will spawn Palkia, Dialgia, or Giratina, and they will have your Trainer ID and obey you without a fuss.

** One of the most powerful even among OlympusMons -- not surprising from a Pokémon that literally created the universe. Of course, you'll never see it in the Battle Tower, most official tournaments, or random Wi-Fi.
** In ''VideoGame/PokemonConquest'', you're forced to use it for the final battle with Nobunaga, so it gets a 70% link rate and awesome stats, Judgment hits all eight tiles around it and ignores type resistances, and its Omnipotent ability grants it various buffs including HP recovery every turn. If you lose, it'd pretty much have to be on purpose.

* SoProudOfYou: When you defeat them in their boss fight in ''Legends: Arceus'', Arceus praises your commitment and devotion to see the task it gave you to its end.

* NoBiologicalSex: {{Averted|Trope}}. Unlike most other Legendary Pokémon, it can be conventionally male or female. The only other Legendary to share this feature, Kubfu (and Urshifu, its evolution), is still predominantly male whereas Heatran has a 50/50 ratio.

* WorfHadTheFlu: Regigigas has its impressive stats cut in half thanks to Slow Start, representing itself as still recovering from a long hibernation. For that reason, it can be somewhat easy to take it down during those first five turns compared to when it finally gets itself prepared to use the full might of its capabilities.

* MinorMajorCharacter: It created ''the entire Pokémon universe'' and the beings that control time, space, the Distortion World, and spirit. And yet, thanks to being a Mythical Pokémon (and one that wasn't officially revealed until after its debut in the Sinnoh games), it's not even a blip on Team Galactic's radar (or, for that matter, anyone else's). It didn't get its own game centered around it until ''Pokémon Legends: Arceus'', over a decade after the release of ''Diamond'' and ''Pearl''. Even then it only appears at the very beginning and very ending of the story.

* PhysicalGod: One of the most powerful Pokémon is in a physical form that can be fought. In ''Film/PokemonDetectivePikachu'', the main characters arrive in the office of the (seemingly) HonestCorporateExecutive who owns the statutes of Palkia, Dialga, and Arceus which indicates someone or at least him knows who Arceus is while Pikachu makes a "[[HoldYourHippogriffs Sweet mother of Arceus]]" comment.

* TimeAbyss: [[OlympusMons Legendary and Mythical Pokémon]] tend to be this by default but Arceus stands out even amongst them. Its designations as "the Alpha Pokémon" and "the Original One" indicate its great age and it is heavily implied to be the creator of the Pokémon universe. Arceus is even older than time itself, as it is explicitly credited with creating Dialga, Palkia, and Giratina, with Dialga's Pokédex entry stating that time itself started to flow when it was born.
* TopGod: '''The''' undisputed most powerful entity in the Pokémon mythos. Other Legendries in the lore are the embodiments of concepts, but Arceus flat out created the universe.

* BlackSheep: Giratina counts, being the most chaotic of the trio.
