Off the top of my head:
- Latios and Latias shiny color comes from adding green to red and blue.
- Trading between different language games in Gen. I was possible, but it would cause severe glitches and corruption.
- Similarly, you can trade pokemon holding mail in Gen. II between languages with slightly different character sets, which would also cause glitches.
- Gen. III featured fully functional international trading. However the japanese games' higher character limit would cut off names.
- Twineedle could poison steel types.
- Jolteon can learn Pin Missile.
- In Red & Blue, if you listen to the Jigglypuff singing in the Pewter Pokémon Center, the tune is the same as Jigglypuff's song in the anime.
- Flying is the only type that is not the primary type — or even the pure type — of any Pokémon (ignoring Arceus with the Sky Plate).
- Other than Flying, the Steel type has the fewest number of Pokémon with that as a pure type; the only pure Steel Pokémon are Mawile, Registeel, and Arceus with the Iron Plate.
Arceus is an anagram for Saucer
Did you know that in Yellow, you can make pikachu happy by giving it potions when it's at full hp?

Speaking of firered and leafgreen, Nintendo thought about changing green to blue in the international versions(as it was with the originals) even to the point of trademarking the name WaterBlue.
And because Arbok has no limbs, it's measured in length and can enter buildings. Snakewise.
In gen 1 bulbasaur had a double weakness to bug.
