>>56858455Primarina is a mermaid, that is, it lost its sea lion anatomy when it evolved, remember that Pokemon are monsters first and foremost. Sea lions have hind limbs turned into fins and have a small tail, whereas Primarina lost its hind fins and formed a giant tail like Sirenians or Delphinidae, just look at the length of its body, this to resemble medieval sirens or Greek Nereids.
As for Gardevoir, it's GF's choice, but I like the idea that her hair becomes keratinized like the plates of a pangolin, forming a natural helmet (Sirknight)
