Have the base stats of any Pokemon increased or decreased from a previous generation into a new generation?

Title should be self explanatory. If you had, say an Arceus, in Generation four and had 100 in each base stat (I know it didn’t, I’m using it as an example) and then its base stats got increased by 20 to 120 in generation five. I’m basically looking for any Pokemon that has done that. Or decreased, doesn’t have to be increased only.

Yes. The first instance of this, while not a direct change to the actual base stat values, occurred in Gen 2 with thesplit of the Special stat from Gen 1. The Special stat was replaced by Special Attack and Special Defence, so Gen 1 Pokemon effectively received brand new base stats. Each Pokemon’s old Special stat lives on through its SpA stat or its SpD stat.

Between Gen 5 and Gen 6, a variety of Pokemon experienced direct base stat changes. The list of these Pokemon,according to Serebii, can be found below:

Once again, between Gen 6 and Gen 7, base stat changes occurred. They are listed as follows (creditKaphotics):

Between Gen 7 and Gen 8, Aegislash’s base Defence and Special Defence were both reduced from 150 to140.
