Our Cryptids Are More Mysterious: Unlike a lot of Pokémon that often have in-depth descriptions, these Pokémon are enigmas with scarce information and extremely rare sightings. The exceptions are Koraidon and Miraidon, who were originally known as Winged King and Iron Serpent respectively, before being given 'proper' names by Professor Sada/Turo. Only Known by Their Nickname: Unlike most Pokémon, the Paradox Pokémon's names are only descriptions of what they are rather than legitimate names. Odd Name Out: In contrast to native Pokémon, Paradox Pokémon don't have names in the typical manner for the franchise. Koraidon and Miraidon are exceptions, having mirrored stat spreads of each other instead. Numerological Motif: All Ancient Pokémon's base stats are odd numbers, all Future Pokémon's are even. Self explanatory with the future Pokemon given they’re cybernetic androids. No Biological Sex: They're officially genderless, though with more of an implication that their biology hasn't been properly researched, so like with Ultra Beasts, the Pokédex simply lacks the ability to determine their genders. Lurid Tales of Doom: The Pokédex descriptions for each of the Paradox mons in the opposite version are derived from paranormal magazines, and as such have rather wild theories about the Pokémon usually based on no actual evidence. And the future Paradox Pokémon, exclusive to Violet, have robotic versions of Hydreigon and Tyranitar, who are both exclusive to Scarlet. Irony: Despite the past Paradox Pokémon being exclusive to Scarlet, two are based on Misdreavus and Salamence, who are exclusive to Violet. Hair-Trigger Temper: Most Paradox Pokémon have the "attack on sight" temperament, and will charge the moment they see you. Fish out of Temporal Water: They were brought to the present from the ancient past (in Scarlet) or the distant future (in Violet) by a time machine. The following fight against the "Guardian of Paradise" Koraidon/Miraidon is somewhat scripted. Both will be sent out last, holding Booster Energy to activate their abilities without sunlight for the former or Electric Terrain for the latter. Final Boss: Roaring Moon for AI Sada in Scarlet, and Iron Valiant for AI Turo in Violet. Dub Name Change: Since they're only known by codenames, they join Type: Null as the only Pokémon with unique Spanish and Italian names. Iron Crown is part-Psychic instead of part-Fighting. Iron Leaves is part-Psychic instead of part-Fighting. Iron Valiant is Fairy/Fighting instead of either Psychic/Fairy or Psychic/Fighting. Iron Thorns is part-Electric instead of part-Dark. Iron Moth is part-Poison instead of part-Bug.
Iron Jugulis is part-Flying instead of part-Dragon.Iron Bundle is part-Water instead of part-Flying.Sandy Shocks is part-Ground instead of part-Steel.Roaring Moon is part-Dark instead of part-Flying.Slither Wing is part-Fighting instead of part-Fire.Brute Bonnet is part-Dark instead of part-Poison.Scream Tail is part-Psychic instead of part-Normal.Most of the Pokémon they are based on are dual-typed, and the Paradox Pokémon share exactly one type with their contemporary relatives, while substituting the other type for a different one. Discard and Draw: Both played straight and inverted.It doesn't help that the only other "lore" available for them consists of paranormal magazine articles which are explicitly noted to have all been made up by the authors of the articles, at most said authors being simply inspired by the descriptions of the creatures in the Scarlet/Violet Book. Just what time period they supposedly come from is likewise unknown, as only the Pokémon themselves can be brought from it, no fossils of the ancient ones are known, and no other observations are possible without becoming trapped in the past or future.
Said paradox is how it was most of them are described in the Scarlet/Violet Book as having existed in the Great Crater of Paldea long before Sada/Turo built their time machine (which was built specifically because there were no past/future Pokémon present), raising questions of just where they really come from and what power is causing them to appear. Ambiguous Situation: They're described in-story as Pokémon brought from the past and future, but their history carries a big paradox, suggesting that it might not be the actual past or future that they're being brought from, but the truth remains unclear.
