Natures
Every Pokémon is born with one of 25 natures and keeps it for good. Twenty of them raise one stat by 10% and lower another by the same amount, five do nothing. The choice comes down to one question: which stat does this Pokémon not use anyway.
A nature never changes HP. It is the only stat out of its reach, so no nature can make a Pokémon bulkier that way.
