Hmm...Romantically yes...but, well platonically.
I think it would probably be taboo, since my mind is actively blocking the horror of what somebody could do with a Ditto.
That came to my mind as well. It's the fact that their bodies are incompatible.
Well, I'm not saying "this" is absolutely necessary but..."that" would be normal to be desired...when someone is in love with somebody. But...I don't think this could happen (or lets say I wouldn't wanna know). It works different for Pokemon.
Since we're human we're supposed to feel this way for other human. So I think it's possible to love Pokemon...just don't like this.
Besides this, I think lovers have to be eqal, also they have to communicate properly. Think about it: You couldn't talk something over, you couldn't even talk about problems.
Not only because they can't speak (if you go with the anime it could be possible to learn after all---> Meowth )but because there is a huge difference between a normal human life in a human society and a Pokemon living in a Pokemon society (in the wild? ) What I mean is:
There are some human only problems, since their normal life just works differerently.
Sice the title of this thread mentiones Pikachu, take it as an example: Ash and it may be good friends but...would you call them eqal? Does he share every thought with it, does he talk about Problems, can he start some kind of real conversation (I know you can do without speech...but I mean does he try to communicatemore intensive with than just the usual guessing what it wants to express in a short moment)?
If such a realtionship should work the Piokemon would need to adapt to human lifestyle I think.Kinda like Meowth (come to think about it; he did it for love...to be more human).
I can't see a human adapting to Pokemon lifestyle.
I hope someone understands what I wanna express here..
