>>36557274>Idol singerYou seem to have confused Primarina for Brionne, the prevolution. Primarina is based on an opera singer- hence, the long hair and the dress, and the names "Sparkling Aria" and "Oceanic Operetta" for its moves.
That, and it's also not just a seal. It's a selkie- some sort of Irish fey creature that shapeshifts into a seal. Hence the Fairy typing. Specifically, it takes inspiration from Song of the Sea, hence the musical subtheme.
As for the "pre-assigned personality" thing... A, that's Brionne again, not Primarina, and B, it's doesn't really? All that's pre-assigned is that the seal, while it's a Brionne, hides its true personality behind a mask. It acts. Because it's a performer. Because it sings songs, because it's a selkie.
>>36557309Yes, because you literally don't have the capacity to have it not be able to breed with males.
That being said, if the Primarina were a living, breathing being instead of a mass of pixels and data, your attempts to "make it female" would indeed make it a tranny instead of a full female. Because you wouldn't be able to use your God powers to twist the hairs of fate/lines of code, and magically make it a female.
