History Trivia / PokemonDiamondAndPearl

** The Generation IV games have a ???-type Arceus in their coding, with a slate blue coloration, to match the ???-type existing for the move Curse. There's no way to access the forme without hacking in a corresponding Plate, and it is longer present from ''[[VideoGame/PokemonBlackAndWhite Black and White]]'' onward due to the ???-type's removal.

** The starters' English names were to be Sproutle, Scorchimp, and Ploopil instead of Turtwig, Chimchar, and Piplup. Turtwig's category was also going to be the "Greenleaf Pokémon" instead of the Tiny Leaf Pokémon. At least one trailer for the Diamond and Pearl era of the anime was made with Turtwig's beta name.

** A beta sprite leak revealed most Pokémon had beta gender differences, most of which were later scrapped. Some of this follows real-life logic; like that most or all of the male horned Pokémon have bigger horns than the females, but some are a bit stranger, like many female Pokémon having smaller ears, which makes no sense as this type of sexual dimorphism has never occurred in real-life. The decision to scrap all of these may have to due with all these sprites needing to be animated, and there are plenty of differences that would have just made the females needlessly uglier or less desirable to players. Some specific examples:
*** Female Charizard bizarrely has only a single ugly horn on her head instead of two. This is believed to be a reference to [[DevelopmentGag early official art that portrayed Charizard with one horn]].

* ContentLeak: Thanks to early copies getting out into the wild, ''Brilliant Diamond and Shining Pearl'' leaked about two weeks before their intended release.

* ChristmasRushed: Early leaked copies of ''Brilliant Diamond and Shining Pearl'' revealed the base game lacked a proper introductory and ending movies, and had some of its post-game content (namely, Ramanas Park) inaccessible. Incidentally, it was announced soon after that these features [[https://www.nintendo.com/whatsnew/detail/2021/pokemon-brilliant-diamond-and-pokemon-shining-pearl-feature-update/ would be added later on via]] [[DownloadableContent a day-1 patch]].

** A leak in 2020 revealed that the beta designs for Giratina and Arceus, while most likely placeholders, still looked very different from their final counterparts, with Giratina being a six-legged chimera-like being with feathery wings/crest and a two-tentacled mouth - far more mammalian in appearance than the reptilian appearance of the final - and Arceus being a quadrupedal, amorphous, shadowy entity. Darkrai's beta design was also more humanoid and corporeal than the final version.

* ChristmasRushed: Early leaked copies of ''Brilliant Diamond and Shining Pearl'' revealed the base game lacked a proper introductory and ending movies, and had some of it's post-game content (namely, the Ramanas Park) inaccessible. Incidentally, it was announced right after that these feautures would be added later on via [[DownloadableContent a day-1 patch]].

* ContentLeak: Thanks to early copies getting out into the wild, ''Brilliant Diamond and Shining Pearl'' leaked about two weeks before their intended release. Nintendo obviously did not handle it well, to point of even ''bricking the main leaker's Nintendo Switch''.

* BTeamSequel: Not the original games, but the ''Brilliant Diamond and Shining Pearl'' remakes for the UsefulNotes/NintendoSwitch. They are being developed externally by a company called [=ICLA=], while Creator/GameFreak works on ''VideoGame/PokemonLegendsArceus''.

** [[https://tcrf.net/images/d/db/PokemonDiamondPearlPrototypeGymLeaders.png Beta sprites]] of the Sinnoh Gym Leaders have been discovered, showing that many of them lacked their signature accessories in the game's planning stages. Roark had brown hair instead of red and didn't wear glasses, Gardenia didn't have her black headband, Maylene's hair was shorter and she didn't have a nose bandage, Crasher Wake had a different mask that covered his face and resembled a Swampert's head, Byron's hair was smoother and less spiky, Candice had blue eyes instead of brown, and Volkner had brown eyes instead of blue.

* {{Jossed}}: For a while, Lucario was believed to be a Legendary or Mythical Pokémon, due to being the central character of a [[Anime/PokemonLucarioAndTheMysteryOfMew Pokémon film]] (a role back then only delegated to Legendaries or Mythicals). These games dismiss the theory.

* NamesTheSame: Pokemon Diamond is not to be confused with a bootleg version of ''VideoGame/{{Telefang}}''.

** Canalave and Snowpoint City were both intended for ''Pocket Monsters 2'' (as places known as New Type and North/Blue Forest respectively) but were cut. They're brought back here, slightly modified. As a [[DevelopmentGag nod to this]], the Canalave City music is a remix of the Gen II credits music.

* TrollingCreator: The developers programmed an NPC who will trade you a Haunter in exchange for a Medicham. It's common knowledge that Haunter evolves into Gengar upon being traded, and said Pokémon is a fan favourite both in terms of design and competitively. However, the Haunter that is given to you is holding an Everstone, an item that ''prevents it from evolving''. To rub salt in the wound, talking to the NPC afterwards causes her to giggle and confess she knew full-well that the player would feel disappointed.
