Early on they were either just some roughly elemental monster - Nidoking, Skarmory, Aggron.
Or built around one concept combined with an animal or otherwise animated - Blastoise, Fortress, Breloom.
Later on you got more composite designs.
Generally starting with Gen 4, Empoleon being a Water Penguin+Ice breaker+Napoleon, for example.
This became more and more a standard as it went forwards. By Gen 6 I think that at least in many cases it was now the default design system being used.
I think people don't like the composite designs as much because they're more complex and trend towards mixing in more human elements.
