5 fun facts about Paradox Pokemon
1) Reverse Version-exclusives

One interesting fact about certain types of Paradoxes in the franchise is in regards to how they were distributed between games. Version-exclusive Pokemon that received Paradox variants like Tyranitar and Salamence appear in games opposite of their futuristic or prehistoric counterparts.
This gives trainers some kind of a way to obtain critters that they may have otherwise missed out on. This was most likely intentional on Game Freak's behalf for this very reason. The only exception to this rule is Paradoxes based on Legendary Trios like Iron Crown or Raging Bolt.
2) Odd size differences

One of the patterns shared between creatures and their variants is in regards to their sizes. Those that came from the past are larger than their modern-day counterparts, while those that arrived in Paldea from the future are much smaller than their modern relatives.
While not too important to the gameplay, outside of helping to remember damage calculation for moves like Low Kick and Grass Knot, this is just a fun pattern that not many players would normally pay attention to. It does make sense considering the primal Paradoxes are much bulkier, while the futuristic robotic Paradoxes are more sleek and compact.
3) Koraidon and Miraidon are Paradoxes

Much like Necrozma, Solgaleo, and Lunala and Ultra Beasts, Koraidon and Miraidon are Paradox Pokemon, as well as Legendaries. These creatures also have amazing synergy with the Paradoxes from their respective versions as well, with their signature abilities activating those of the other Paradoxes.
These two Legendary Pokemon are past and future versions of Cyclizar, a new creature introduced in the ninth generation. Trainers can be seen riding this monster in various cities around the Paldea region, and Cyclizar even had a strong start in the competitive scene when the games first released.
4) Pulseman reference

Pulseman was a franchise created by Ken Sugimori before he went on to create Pokemon. This franchise featured a half-human, half-AI hero named Pulseman, who was created when a human scientist bound his DNA with an AI program core to make the first C-Life AI that can exist outside of a computer.
Some fans have noticed a potential reference to this series made in the recent Scarlet and Violet titles. References to Pulseman have been seen various times in the franchise's history, so seeing one is not out of place. In Iron Jugulis' Scarlet Pokedex entry, it is said that Iron Jugulis came to be after a Hydreigon fell in love with an AI, much like Pulseman's origins.
5) Lore with Evolutionary Stones

Flutter Mane, Sandy Shocks, and Scream Tail are three Paradox creatures based on Pokemon that are not fully evolved. This is a detail that stuck out to many players when these Paradoxes first debuted. However, these creatures have a similar trait among each other: they all require stones to evolve.
Misdreavus and Jigglypuff have always required stones, but Game Freak recently made Magnezone much more accessible by only requiring players giving their Magneton a Thunder Stone to evolve into Magnezone. Since these creatures are from the ancient past, this could mean that Evolutionary Stones did not exist for whatever reason.
